A New Species

 We describe a new species of snake of the genus Cylindrophis Wagler, 1828 from Boano Island, northern Maluku         Province, Indonesia. Cylindrophis osheai sp. nov. differs from all congeners by a combination of the following eidonomic characters: (1) 19 dorsal scale rows at midbody; (2) 224−226 ventral scales; (3) 8−9 subcaudal scales; (4) 25−28 dark ventral blotches, aligned to form a broad, wavy stripe along most of the body; (5) a dark ventral pattern that is completely separated from the dark dorsal coloration; (6) an almost completely dark ventral surface on the tail; (7) a dark bar running from the eye through the 3rd and 4th supralabials to the mouth; and (8) a dark, double-diamond-shaped ventral blotch in the area immediately posterior to the genials. Eidonomic species separation from other Cylindrophis species is supported by differences in cranial osteology, as elucidated by micro-computed tomography images. Diagnostic features of the cranium include (1) well-developed postorbitofrontals that project laterally beyond the maxilla in dorsal view, creating a characteristic, horn-like appearance; (2) a broad parietal with a bulbous middle section; (3) 10–12 maxillary teeth; (4) nine        palatine teeth; (5) 7–9 teeth on the pterygoid; and (6) 11–13 teeth on the dentary. We also provide notes on the taxonomic history of Cylindrophis melanotus Wagler, 1828 and an identification key to the Moluccan species of the genus.

A New Species

AbstractLargocephalosaurus polycarpon Cheng et al. 2012a was erected after the study of the skull and some parts of a skeleton and considered to be an eosauropterygian. Here we describe a new species of the genus, Largocephalosaurus qianensis, based on three specimens. The new species provides many anatomical details which were described only briefly or not at all in the type species, and clearly indicates that Largocephalosaurus is a saurosphargid. It differs from the type species mainly in having three premaxillary teeth, a very short retroarticular process, a large pineal foramen, two sacral vertebrae, and elongated small granular osteoderms mixed with some large ones along the lateral most side of the body. With additional information from the new species, we revise the diagnosis and the phylogenetic relationships of Largocephalosaurus and clarify a set of diagnostic features for the Saurosphargidae Li et al. 2011. Largocephalosaurus is characterized primarily by an oval supratemporal fenestra, an elongate dorsal ‘rib-basket’, a narrow and elongate transverse process of the dorsal vertebrae, and the lack of a complete dorsal carapace of osteoderms. The Saurosphargidae is distinct mainly in having a retracted external naris, a jugal–squamosal contact, a large supratemporal extensively contacting the quadrate shaft, a leaf-like tooth crown with convex labial surface and concave lingual surface, a closed dorsal ‘rib-basket’, many dorsal osteoderms, a large boomerang-like or atypical T-shaped interclavicle. Current evidence suggests that the Saurosphargidae is the sister-group of the Sauropterygia and that Largocephalosaurus is the sister-group of the Saurosphargis–Sinosaurosphargis clade within the family.

A New Species

To date the genus Diploplastron comprised only one species of ophryoscolecid ciliate, Diploplastron affine, which is characterized by having two retractable ciliary zones in the anterior end of the body, two slender and juxtaposed skeletal plates on the right side, a rod shape macronucleus, and two contractile vacuoles. During study on the characterization of rumen ciliate community composition in Brazilian domestic sheep, we observed ciliates with atypical morphology but with diagnostic features of genus Diploplastron. This study describes Diploplastron dehorityi, a new species of ophryoscolecid ciliate, that differs from D. affine, primarily, in the morphology of skeletal plates, morphology of nuclear apparatus and body shape. In addition to the similarities between the new species and congener species, D. dehorityi has some morphological similarities to species of genus Eremoplastron.

A New Species

A half a century ago, R. T. Leiper described a new species belonging to the genus Fasciola from specimens which he collected from hippopotami at the Murchison Falls, on the Victoria Nile in Uganda, in the summer of 1907. This species, Fasciola nyanzae, was found in the bile ducts of the liver, and in most instances the specimens were somewhat macerated owing to the length of time that had elapsed before the animal could be recovered from the water. Nevertheless, the characteristic shape of these liver flukes and the restriction of the branched testes to the anterior third of the body made it possible to recognise them as being different from all other species of the genus known at that time.

Abstract The Cambrian radiation represents a key time period in the history of life. Here, we add to the mounting evidence accumulating on the nature of deuterostomes from this time period through description of a new species of stalked deuterostome, Herpetogaster haiyanensis nov. sp., from the lower Cambrian (series 2, stage 3) Chengjiang biota of China. This represents the first occurrence of the genus in Gondwana, the first juvenile specimen, and the oldest specimens to date. Herpetogaster haiyanensis nov. sp. differs from H. collinsi Caron et al. (2010) in having a stolon that is separated into an outer and inner layer, the segmentation of the body and in the shape and number of branches of the tentacles. The new species reiterates earlier suggestions of deuterostome affinities of the genus―it appears closely related to Phlogites and then successively more distantly related to Cotyledon and Eldonia―and may have fed on hyolithids.

A New Species

The genus Thamnodynastes is the most diverse within the tribe Tachymenini, with an extensive and complex taxonomic history. The brief descriptions and lack of robust diagnostic characters are the main sources for identification errors and for the difficulty to assess the diversity estimates of the genus. The Thamnodynastes pallidus group was briefly designated to encompass the most arboreal species of the genus, with thinner bodies and longer tails: T. pallidus, T. longicaudus, T. sertanejo, and a fourth undescribed species. After its designation, no other paper addressed this group and its morphological variation, especially for the hemipenis, is still undetermined. After the analysis of all species of Thamnodynastes we were able to corroborate the distinctiveness of the T. pallidus group and to accurately diagnose its fourth species from the western portion of the Amazonia lowlands. The new species is distinguishable from all congeners, except T. sertanejo, by the absence of ventral longitudinal stripes, 17/17/11 dorsal scale rows, and dorsal dark brown blotches on the anterior third of the body. The new species is distinguished from T. sertanejo by the higher number of subcaudals, lower number of ventrals, and smaller body and head sizes. We also provide additional diagnostic features for the Thamnodynastes pallidus group, including new data on hemipenial variation. Finally, we briefly discuss the defensive behavior and morphological characters associated with arboreality in members of the T. pallidus species group.

Pseudotachinus bilobus Yin and Li, new species, is described from the border of Guizhou and Guangxi, southern China, with habitus and diagnostic features illustrated. The new species is distinct, and can be readily separated from all other congeners by the complete lack of microsculpture on the dorsal surface of the body, strongly transverse elytra, and unique forms of male and female sternites VIII. In addition, P. assingi Schülke is recorded from a new locality in Yunnan. The latest identification key and distributional map of Pseudotachinus are modified to include the new data.

A New Species

A new species of Nesolinoceras Ashmead from the Dominican Republic is described and illustrated. A key to the species and a revised and expanded distribution map is presented. This is the third species recognized for the genus, and the first one confirmed to occur in high altitude (1100 m). When compared with the previously known species, a number of unique and shared features emerged, supporting a redefinition of the genus beyond that of Santos (2016): (1) the known inter-specific variability of 48% of the examined characters increased considerably, confirming their diagnostic value at the species-level, and (2) the stability of six features support them as additionally diagnostic for the genus: 22–23 flagellomeres; mesoscutum subcircular, as long as wide; scuto-scutellar carina absent, axillary trough shallow, indistinct on scutellum; subalar ridge wide, somewhat ovoid, not keeled; crossvein 1cu-a arising basad of vein 1M+Cu by about 0.3 its length; and vein 2-M only slightly longer than vein 3-M. Furthermore, two important measurements for the diagnosis of Nesolinoceras now have new, expanded ranges: areolet 1.8–2.6 as long as pterostigma width, and areolet 0.7–1.0 as long as wide. The new taxon is readily recognizable by having the body mostly brown, fully infuscated wings, and the longest ovipositor of the species, among other diagnostic features. A new geographic record and in situ photo are also provided for N. laluzbrillante Santos.

Brachysomus (Hippomias) tannourinensis sp. nov. is described from Lebanon, compared with similar Brachysomus species, and its main diagnostic features are figured. The new species was discovered at the ancient cedar forest of Tannourine as the first known representative of the genus Brachysomus in Lebanon. It is easily recognizable by the body vestiture consisting of two types of scales, the prolonged shape of the  rostrum, and the parallel-sided penis.

Abstract—A new species of Eugenia from the Atlantic forest of Brazil is described and illustrated. Eugenia flavicarpa is restricted to the Floresta de Tabuleiro (lowland forests) of Espírito Santo state and is nested in Eugenia subg. Pseudeugenia. Considering all other species of the subgenus that occur in forest vegetation types of the Atlantic forest phytogeographic domain, Eugenia flavicarpa can be distinguished mainly by the combination of smooth leaves with indumentum on both surfaces, with two marginal veins, usually ramiflorous inflorescences, pedicels 4.5‐9.7 mm long, flower buds 3.5‐4 mm in diameter, and by the calyx lobes that are 2‐3 mm long with rounded to obtuse apices. Morphological analyses were performed to explore the significance of quantitative diagnostic features between the new species and the closely related species, Eugenia farneyi. Notes on the habitat, distribution, phenology, and conservation status of Eugenia flavicarpa are provided, as well as a key for all species of Eugenia subg. Pseudeugenia from forest vegetation of the Atlantic forest phytogeographic domain.
