 Scinax onca
Ferrão, Moravec, de Fraga, de Almeida, Kaefer & Lima, 2017 

A new tree frog species of the genus Scinax from the interfluve between the Purus and Madeira rivers, Brazilian Amazonia, is described and illustrated. The new species is diagnosed by medium body size, snout truncate in dorsal view, ulnar and tarsal tubercles absent, nuptial pads poorly developed, skin on dorsum shagreen, dorsum light brown with dark brown spots and markings, white groin with black spots, anterior and posterior surfaces of thighs black, and iris bright orange. The advertisement call consists of a single short note, with 16−18 pulses and dominant frequency at 1572−1594 Hz. Tadpoles are characterized by body ovoid in dorsal view and triangular in lateral view, tail higher than body, oral disc located anteroventrally and laterally emarginated, dorsum of body uniformly grey-brown with dark brown eye-snout stripe in preservative, fins translucent with small to large irregular diffuse dark brown spots.

Scinax onca sp. n.

Diagnosis: A medium-sized species of Scinax characterized by the following combination of characters: (1) SVL 31.3−34.5 mm (n = 13) in males and 35.5−40.4 mm (n = 4) in females; (2) snout truncate in dorsal view, bluntly rounded in lateral view; (3) tarsal tubercles absent; (4) tubercles on lower jaw and knee absent; (5) skin on dorsum shagreen; (6) dentigerous processes of vomers triangular; (7) in life, ground colour of dorsum light brown with dark brown spots and markings; dorsolateral stripes or X-shaped blotch on dorsum absent; flanks light brown with or without dark brown spots; axillar region and groin white with black irregular spots; anterior and posterior surfaces of thighs black (usually bordered by an irregular white streak); webbing between toes black; belly white to yellow, with round dark brown spots; iris bright orange; (8) advertisement call consisting of a single pulsed note; note duration 102−121 ms; 16−18 pulses/note; dominant frequency 1572−1594 Hz; (9) tadpoles with body triangular in lateral view; labial tooth row formula 2(2)/3(1); labial arm absent.

Etymology: The specific name onca refers to the Brazilian common name for the jaguar Pantera onca (Linnaeus, 1758) due the blotchy colour pattern of the new species. Furthermore, the specific name is a reference to frequent encounters of P. onca during the fieldwork in the PMI. The name is used as a noun in apposition.

Distribution and ecology: Scinax onca sp. n. is an exclusive forest dweller, known from two small areas located in the middle section of the PMI (State of Amazonas, Brazil), and two small areas lying in southern part of PMI, close to municipality of Porto Velho (Rondônia, Brazil). The maximum straight distance between the localities is around 500 km (Fig. 1). The middle PMI is covered by tropical lowland rainforest characterized by closed canopy with emergent trees whereas the southern part has a more open lowland rainforest formation with frequent palm trees.

The new species is an explosive breeder. All specimens were encountered after (or during) heavy rains when aggregated at middle-sized or large temporary forest ponds. The ponds were not connected to streams. The males were calling from shrubs growing in or next to the water. Calling males adopted both horizontal and vertical positions on leaves and shrub trunks ca. 50–200 cm above the ground. Other tree frogs found in sympatry with S. onca sp. n. included Dendropsophus leucophyllatus (Beireis, 1783), D. marmoratus (Laurenti, 1768), D. minutus (Peters, 1872), D. parviceps (Boulenger, 1882), D. rhodopeplus (Boulenger, 1882), D. sarayacuensis (Shreve, 1935), Phyllomedusa vaillantii Boulenger, 1882, and Scinax sp. 7 (sensu Ferrão et al. 2016).

[Herpetology • 2017] Hemidactylus kangerensis • A New Large Species of Gecko of the Genus Hemidactylus Oken, 1817 (Sauria: Gekkonidae) from the Eastern Ghats, India

Hemidactylus kangerensis
Mirza, Bhosale & Patil, 2017

A new large species of gecko superficially resembling Hemidactylus maculatus Duméril & Bibron and its allied large Hemidactylus is described from Eastern Ghats. The new species, Hemidactylus kangerensis sp. nov. can be easily distinguished from members of the H. maculatus complex based on the number of femoral pores, i.e. 18–21 on each side, separated medially by 4 non-pored scales. A phylogenetic analysis based on partial sequence of mitochondrial gene cytochrome b shows that the gecko is a member of the “H. prashadi” clade and is sister to H. maculatus, from which it differs in an uncorrected pairwise sequence divergence of 10%. The discovery of a new large gecko from Eastern Ghats advocates the need for biodiversity assessment across the neglected Eastern Ghats.

[PaleoOrnithology • 2017] Junornis houi • Flight Aerodynamics in Enantiornithines: Information from A New Chinese Early Cretaceous Bird

Junornis houi 
Liu, Chiappe, Serrano, Habib, Zhang and Meng, 2017


We describe an exquisitely preserved new avian fossil (BMNHC-PH-919) from the Lower Cretaceous Yixian Formation of eastern Inner Mongolia, China. Although morphologically similar to Cathayornithidae and other small-sized enantiornithines from China’s Jehol Biota, many morphological features indicate that it represents a new species, here named Junornis houi. The new fossil displays most of its plumage including a pair of elongated, rachis-dominated tail feathers similarly present in a variety of other enantiornithines. BMNHC-PH-919 represents the first record of a Jehol enantiornithine from Inner Mongolia, thus extending the known distribution of these birds into the eastern portion of this region. Furthermore, its well-preserved skeleton and wing outline provide insight into the aerodynamic performance of enantiornithines, suggesting that these birds had evolved bounding flight—a flight mode common to passeriforms and other small living birds—as early as 125 million years ago.

Junornis houi gen. et sp. nov.

Fig 1. Slab (BMNHC-PH 919a) (A) and counterslab (BMNHC-PH 919b) (B) of Junornis houi.

Holotype: A nearly complete and articulated skeleton (BMNHC-PH 919; Beijing Museum of Natural History) contained in two slabs (a, b). While the skeleton is preserved as voids of the bony elements, it is surrounded by feather impressions defining the surface of its wings and body outline (Fig 1).

Horizon and locality: Yixian Formation, Early Cretaceous (~ 126±4 mya); Liutiaogou Village, Daming Town, Ningchen County, Inner Mongolia Autonomous Region, China.

Etymology: The generic name Jun is derived from a Chinese character () meaning beautiful; ornis is Greek for bird. The species name, houi honors Dr. Hou Lianhai and his important contributions to Chinese paleornithology.

Diagnosis: A small Cathayornis-like bird distinguishable from other similar enantiornithines by the following combination of characters: rounded craniolateral corner of sternum (more angular in Cathayornis yandica and Houornis caudatus); distinct trough excavating ventral surface of mediocranial portion of sternum; triangular process at base of sternal lateral trabecula (absent in H. caudatus and E. walkeri); sternal lateral trabecula broad (much wider than in C. yandica, E. walkeri, and H. caudatus) and laterally deflected (straight in C. yandica and E. walkeri); sternal intermediate trabecula nearly level with mid-shaft of lateral trabecula (significantly shorter in C. yandica, H. caudatus and E. walkeri); sternal xiphoid process level with lateral trabeculae (trabeculae project further caudal in H. cautus and C. yandica); costal processes of last two penultimate synsacral vertebrae three times wider than same process of last synsacral vertebra; and very broad pelvis.

The discovery of Junornis houi, the first published record of a Jehol enantiornithine from Inner Mongolia Autonomous Region, extends the geographic distribution of these early birds into the eastern portion of this region. The well-preserved wings and overall plumage of BMNHC-PH 919 adds significant information to the poor evidence of wing shape in Enantiornithes. Multiple regressions of skeletal elements and remiges allow estimation of key aerodynamic parameters (aspect ratio and wing loading) for this new enantiornithine. The small size, low aspect ratio, and low wing loading of BMNHC-PH 919 indicate that Junornis houi and other similar enantiornithines could have used bounding as their typical flight mode, especially at high speeds. The general morphology of BMNHC-PH 919 thus supports previous interpretations indicating that most avian flight modes have very ancient origins; bounding flight might have evolved among enantiornithines more than 125 million years ago.

[Herpetology • 2017] Phylogenetic Taxonomy of Hemiphyllodactylus Bleeker, 1860 (Squamata: Gekkonidae) with Descriptions of Three New Species from Myanmar

Hemiphyllodactylus montawaensis 
Grismer, Wood, Thura, Zin, Quah, Murdoch, Grismer, Li, Kyaw & Ngwe, 2017

A phylogenetic taxonomy of the gekkonid genus Hemiphyllodactylus based on molecular, morphological, and ecological data recovered 28 species, including three new species from the upland regions of the Shan Plateau in eastern Myanmar. Hemiphyllodactylus linnwayensis sp. nov. is a forest-adapted species that may also be a human commensal and H. montawaensis sp. nov. and H. tonywhitteni sp. nov. are karst forest-adapted species. The discovery of three new species from montane regions in eastern Myanmar extends the distribution of a larger monophyletic group of Hemiphyllodactylus westward to the eastern edge of the Ayeyrawady Basin through a series of semi-contiguous, parallel mountain ranges originating in western China and northern Thailand. The discovery of the karst forest-adapted H. montawaensis sp. nov. and H. tonywhitteni sp. nov. further emphasizes the unrealized herpetological diversity endemic to karst ecosystems and the need for increased field work throughout such habitats in South-East Asia.

[Herpetology • 2017] Splitting and Lumping: An Integrative Taxonomic Assessment of Malagasy Chameleons in the Calumma guibei complex results in the New Species C. gehringi sp. nov.

Calumma gehringi
Prötzel, Vences, Scherz, Vieites & Glaw, 2017

  Vertebrate Zoology. 67(2)

Calumma guibei (Hillenius, 1959) is a high-altitude chameleon species from the Tsaratanana massif in north Madagascar. Since its description was based on a juvenile holotype, its taxonomic identity is uncertain and little is known about its morphology. A recent molecular study discovered several deep mitochondrial clades in the Tsaratanana region assigned to C. guibei and C. linotum (Müller, 1924). In this paper we study the taxonomy of these clades and clarify the identity of C. guibei. Using an integrative taxonomic approach including pholidosis, morphological measurements, osteology, and molecular genetics we redescribe C. guibei and describe the new species C. gehringi sp. nov. which comprises two deep mitochondrial lineages. In terms of external morphology the new species differs from C. guibei by an elevated rostral crest, the shape of the notch between the occipital lobes (slightly connected vs. completely separated), presence of a dorsal and caudal crest in males (vs. absence), and a longer rostral appendage in the females. Additionally, we analysed skull and hemipenis morphology using micro-X-ray computed tomography (micro-CT) scans and discovered further differences in skull osteology, including a large frontoparietal fenestra, and separated prefrontal fontanelle and naris in C. guibei. Furthermore, we provide a comparison of micro-CT scans with traditional radiographs of the skull. The hemipenes have ornaments of two pairs of long pointed cornucula gemina (new term), two pairs of dentulous rotulae, and a pair of three-lobed rotulae, and are similar in both species, but significantly different from other species in the C. nasutum group. Geographically, C. guibei has been recorded reliably from the higher elevations of the Tsaratanana Massif above 1580 m a.s.l., whereas C. gehringi sp. nov. is found at mid-altitude (730-1540 m a.s.l.) in Tsaratanana and the surrounding area.

Calumma gehringi sp. nov.  

Diagnosis. Calumma gehringi sp. nov. is a member of the phenetic C. nasutum group (Prötzel et al., 2016), because of the presence of a soft, dermal, unpaired rostral appendage, absence of gular or ventral crest and heterogeneous scalation at the lower arm, consisting mostly of tubercles of large diameter (0.4–0.9 mm). Within the genus it is a small-sized, grey to greenish chameleon (SVL 44.7 – 55.5 mm, TL 92.6–123.6 mm) that is characterized by a large rostral appendage of green or blue colour in males and yellow in females when unstressed, occipital lobes that are clearly notched but usually still slightly connected, distinctly elevated rostral crest, absence of axillary pits, presence of a dorsal crest in males, and a unique skull morphology. .....

Available names. Apart from C. guibei there is no other valid species or synonym in the Calumma nasutum group with deeply notched occipital lobes.

Etymology. We dedicate the new species to Philip Sebastian Gehring. His comprehensive molecular phylogenetic study on the Calumma nasutum group was the basis for the description of the new species, and will be instrumental to the resolution of the rest of this complex. The species epithet ‘gehringi’ is a patronym in the Latin genitive form.

[Paleontology • 2017] Avicranium renestoi • A Bird-like Skull in A Triassic Diapsid Reptile Increases Heterogeneity of the Morphological and Phylogenetic Radiation of Diapsida

  Avicranium renestoi Pritchard & Nesbitt, 2017

Illustration: Matt Celeskey‏ @clepsydrops 


The Triassic Period saw the first appearance of numerous amniote lineages (e.g. Lepidosauria, Archosauria, Mammalia) that defined Mesozoic ecosystems following the end Permian Mass Extinction, as well as the first major morphological diversification of crown-group reptiles. Unfortunately, much of our understanding of this event comes from the record of large-bodied reptiles (total body length > 1 m). Here we present a new species of drepanosaurid (small-bodied, chameleon-like diapsids) from the Upper Triassic Chinle Formation of New Mexico. Using reconstructions of micro-computed tomography data, we reveal the three-dimensional skull osteology of this clade for the first time. The skull presents many archaic anatomical traits unknown in Triassic crown-group reptiles (e.g. absence of bony support for the external ear), whereas other traits (e.g. toothless rostrum, anteriorly directed orbits, inflated endocranium) resemble derived avian theropods. A phylogenetic analysis of Permo-Triassic diapsids supports the hypothesis that drepanosaurs are an archaic lineage that originated in the Permian, far removed from crown-group Reptilia. The phylogenetic position of drepanosaurids indicates the presence of archaic Permian clades among Triassic small reptile assemblages and that morphological convergence produced a remarkably bird-like skull nearly 100 Myr before one is known to have emerged in Theropoda.

[Herpetology • 2017] Hypogeophis pti • A New Species of Small and Highly Abbreviated Caecilian (Gymnophiona: Indotyphlidae) from the Seychelles Island of Praslin, and A Recharacterization of Hypogeophis brevis

 Hypogeophis pti 
Maddock, Wilkinson, Nussbaum & Gower, 2017


A new species of indotyphlid caecilian amphibian, Hypogeophis pti sp. nov., is described based on a series of specimens from the Seychelles island of Praslin. The type series was collected in 2013 and 2014, and a referred specimen previously identified as H. brevis Boulenger, 1911 was collected from an unspecified Seychelles locality in 1957. The new species most closely resembles the Seychelles endemic Hypogeophis brevis in being short (maximum known total length in life ca. 120 mm) and long snouted, but differs by having a less anteriorly positioned tentacular aperture and fewer primary annuli and vertebrae. In having only 67–69 vertebrae, H. pti sp. nov. is the most abbreviated extant species of caecilian reported to date.

Hypogeophis pti sp. nov.

Etymology. The specific epithet is in reference to the very small size of the species, one of the smallest of known caecilians. ‘Pti’ is a typical spelling in Seychellois Creole of the French petit/petite (small, in English). For nomenclatural purposes the specific epithet is considered to be a noun in apposition.

[Botany • 2017] Etlingera hamiguitanensis • A New Ginger Species (Zingiberaceae; Alpinieae) from Davao Oriental, Philippines

Etlingera hamiguitanensis  Naive


Etlingera hamiguitanensis Naive, belonging to family Zingiberaceae, is described and illustrated from the Philippines as a new species. Although similar to Etlingera philippinensis, the new species is clearly distinguished by having a shorter and heart-shaped labellum. It is also allied to E. penicillata, however, the new species clearly distinguished by having red sterile bracts.

KEY WORDS: Alpinioideae, Etlingera, Mindanao, Mount Hamiguitan, New species, Philippines.

Etlingera hamiguitanensis Naive, sp. nov.

Diagnosis: Etlingera hamiguitanensis is most similar to Etlingera philippinensis (Ridl.) R.M. Smith, but differs in the shape of the leaf (narrowly elliptic to narrowly obovate vs. broadly lanceolate), ligule (entire oblong, hyaline, reddish transluscent vs. entire triangular–oblong, papery, green) and in pubescent leaves abaxially (vs. glabrous). It also differs by having a shorter and bilobed labellum (vs. longer and entire) and by its 2–3 m tall leafy shoots (vs. 6–7 cm tall). It is also allied to Etlingera penicillata (K.Schum) A.D. Poulsen, but differs significantly in having a pubescent leaf abaxially, a much smaller leaf (30–46 × 5–9 cm vs. 67–74 × 12–14 cm), reddish, ovate to obovate sterile bracts (vs. spatulate, cream), hyaline, reddish, notched ligule (vs. entire, green ligule), inflorescence with larger, one to four flowers (vs. inflorescence with smaller, single flower) and a longer labellum (5.5–5.7 cm long vs. 3.6 to 4.2 cm long).

Distribution: La Union, San Isidro, Davao Oriental. So far, only observed and documented from southern Philippines on Mount Hamiguitan Range Wildlife Sanctuary.

Ecology: Etlingera hamiguitanensis grows as a terrestrial herb on slopes, in shady localities with closed canopy in the buffer zone of Mount Hamiguitan Range Wildlife Sanctuary at elevations of approximately 400– 600 m above sea level. The locality was known for its unique flora because of its ultramafic soil and the species was found in an area which are dominated by different fern species and is near the stream with humid environment.

Etymology: This new species was named after Mount Hamiguitan Range Wildlife Sanctuary, where the collection was made.

[Botany • 2017] Begonia fulgurata • A New Species (sect. Diploclinium, Begoniaceae) from Chiang Mai, northern Thailand

Begonia fulgurata C.-I Peng, C.W.Lin & Phutthai

Begonia fulgurata, a new species from northern Thailand, is here described and illustrated. Begonia fulgurata resembles B. integrifolia, a widespread species in Southeast Asia, in having tubers, erect stem with hairy leaves and a periodically dormant habit. However, the new species is sharply distinct in its lamina densely hirsute (vs sparsely puberulous) and with maroon patches and silvery white veins (vs uniformly green or with white spots); inflorescence densely clothed with glandular hairs (vs glabrous or puberulous); staminate flowers with 2, rarely 3 (vs 4) tepals; staminate and pistillate tepals glandular hairy (vs glabrous). As a deciduous species with basal tubers, together with an erect stem, ovate to broadly ovate leaves, 3-locular ovary, it may be mistaken as a dwarf plant of B. grandis, one of the most widely distributed species in China and the type species of sect. Diploclinium. However, B. fulgurata differs in its leaf upper side with fine silvery (vs green) veins; inflorescence densely glandular hairy (vs glabrous), staminate tepals 2 or rarely 3 (vs 4) and pistillate tepals 5 (vs 3), and ovary glandular hairy (vs glabrous).

Keywords: Chiang Mai; endemic; new species; taxonomy

Currently 54 species of Begonia are recognized in Thailand (Phutthai & Hughes 2016). Many are tuberous and periodically dormant during the dry season, such as some members in sect. DiplociniumParvibegoniaReichenheimiaHeeringia and Monophyllon. All of these species have axile placentae and many were discovered recently, e.g., Doorenbos et al. (1998), Phutthai & Sridith (2010), Phutthai et al. (2014), Phutthai & Hughes (2016). Here we report the discovery of a handsome new species, B. fulgurata, from northern Thailand with partial parietal placentation, which resemble some Begonia sect. Coelocentrum, a relatively large group now of over 70 species (Chung et al. 2014, Peng et al. 2014, 2015a, b) occurring on karst limestone in southern China and northern Vietnam. Members of sect. Coelocentrum are evergreen, stemless rhizomatous, and produce axillary inflorescences and unequally winged fruits. The new species, however, does not fit in sect. Coelocentrum because of its tuberous habit, periodically dormant and erect stems and apical inflorescence and subequal wings. Its overall appearance appears to be allied to sect. Diploclinium. We provide a detailed morphological description, a line drawing and a colour plate to aid in identification of this new species.

Begonia fulgurata C.-I Peng, C.W. Lin & Phutthai, sp. nov.

 Type. Thailand, Chiang Mai Province, Doi Lohn (Lahn), west side, ..., Huay Gayo Subdistrict, Mae Awn District. Sterile specimen collected on 23 Oct. 2005, ....Type specimens pressed from plants brought back for cultivation in the experimental greenhouse of Academia Sinica, 26 Aug. 2008 (holo HAST; iso BKF).

Etymology. The specific epithet fulgurata is derived from the fine, silvery-white venation on the leaf upper surface, which resembles lightning.

[Entomology • 2017] Lusius malfoyi • A New Species of Lusius (Hymenoptera: Ichneumonidae) from New Zealand

Lusius malfoyi
 Saunders & Ward, 2017

Lusius malfoyi n. sp. (Hymenoptera: Ichneumonidae) is described. It is an endemic New Zealand species and the first species of the genus to be described from the Australasian region.

KEYWORDS: Biodiversity, conservation, species description, taxonomy

Figure 1. Lateral habitus. Scale bar = 2 mm.

Lusius malfoyi Saunders and Ward, sp. nov.

Etymology. Noun in the genitive case. This species is named after Lucius Malfoy, a character in J. K. Rowling’s Harry Potter stories, for two reasons. First, the study of parasitoid wasps can be described as an enjoyable and ‘magical’ experience. Second, the fictional namesake and his family have a sinister reputation in the Harry Potter stories. However, in the end their reputations are salvaged. This parallels the way in which many people view ‘wasps’ in a fearful way, even though only a small proportion of wasp species cause damage or harm. We hope that a more nuanced understanding of wasps can be achieved through educating people about their diversity, ecology and behaviour. 

Distribution. Lusius malfoyi is widespread on the New Zealand mainland (North Island and South Island) but has not been collected from offshore islands.

[Gastropoda • 2017] Revision of the Alycaeidae of China, Laos and Vietnam (Gastropoda: Cyclophoroidea) I: The Genera Dicharax and Metalycaeus

in Páll-Gergely, Hunyadi,  Sáng, Naggs & Asami, 2017. Revision of the Alycaeidae of China, Laos and Vietnam (Gastropoda: Cyclophoroidea) I. ....



This is the first part of the revision of the Alycaeidae of China, Laos and Vietnam. Here we revise the species hitherto classified in Chamalycaeus Möllendorff, 1897 (genera Dicharax and Metalycaeus in this study). We show that no Chamalycaeus live in the region, and the alycaeid species of the investigated region can be classified into five genera: Alycaeus Baird, 1850, Dicharax Kobelt & Möllendorff, 1900, Dioryx Benson, 1859, Metalycaeus Pilsbry, 1900 and Pincerna Preston, 1907. We propose Dioryx dautzenbergi Páll-Gergely nom. nov. as a replacement name for Alycaeus (Dioryxmajor Bavay & Dautzenberg, 1900, non Alycæus (Dioryxgranum var. major Godwin-Austen, 1893Alycaeus anceyi Mabille, 1887A. eydouxi Venmans, 1956A. mouhoti L. Pfeiffer, 1862, A. rolfbrandti Maassen, 2006 and A. vanbuensis Bavay & Dautzenberg, 1900 are retained in AlycaeusAlycaeus costulosa Bavay & Dautzenberg, 1912 and A. maolanensis Luo, Zhang & Zhuo 2009 were transferred to Pincerna. We examined newly collected specimens and the type specimens of all species with the exception of the following: A. elevatus Heude, 1886A. expansus Heude, 1890Aneglectus Heude, 1885, Chamalycaeus libonensis Chen, Li & Luo 2003C. panshiensis Chen, 1989, C. tangmaiensis Chen & Zhang, 2001, C. zayuensis Zhang, Chen & Zhou, 2008Fifteen new species are described as follows: Dicharax (?) abdoui Páll-Gergely, n. sp.Dicharax (?) alticola Páll-Gergely & Hunyadi n. sp.Dicharax (?) ellipticus Páll-Gergely n. sp.Dicharax (?) immaculatus Páll-Gergely n. sp., Dicharax bison  Páll-Gergely & Hunyadi n. sp.Dicharax draco  Páll-Gergely & Hunyadi n. sp.Dicharax imitator  Páll-Gergely & Hunyadi n. sp.Dicharax microcostatus Páll-Gergely n. sp., Dicharax micropolitus  Páll-Gergely & Hunyadi n. sp.Dicharax robustus  Páll-Gergely & Hunyadi n. sp.Metalycaeus (?) awalycaeoides  Páll-Gergely & Hunyadi n. sp.Metalycaeus (?) ibex  Páll-Gergely & Hunyadi n. sp.Metalycaeus laosensis Páll-Gergely n. sp., Metalycaeus oharai  Páll-Gergely & Hunyadi n. sp.Metalycaeus (?) okuboi Páll-Gergely & Hunyadi n. sp. A total of twelve names are synonymised with valid species. In this revision we payed special attention to conchological characters hitherto neglected, such as the fine sculpture of the embryonic whorls and the fine structure of the microtunnels along the breathing tube. We described the radula and penis morphology of five Dicharax species.
