A New Species

A new snake species of the genus Hebius is described on the basis of three specimens from Hunan Province, China. The new species can be distinguished from its congeners by a significant genetic divergence of 6.1%–12.9% of the mitochondrial cytb gene and a combination of the following morphological characters: (1) tail long, approximately 25% of the total length; (2) dorsal scale rows 19-19-17, vertebral scales enlarged, smooth, 2nd–10th rows distinctly keeled; (3) anterior temporals 2, preocular 1, postoculars 3; (4) ventrals 160–164; (5) internasals narrowed anteriorly; (6) a pair of occipital spots and a pale postparietal streak; (7) a pale brown or beige dorsolateral stripe on the 4th–6th scale rows; (8) ventral scales brick-red at their outer border, with a row of well-defined dark blotches; (9) maxillary teeth 21, gradually enlarged, followed by 2 moderately enlarged posterior teeth, without diastema; (10) nostrils lateral.

A new species of the Gekko japonicus group is described from Khammouane Province, central Laos, based on morphological characters and molecular data. Morphologically, Gekko nadenensis sp. nov. is differentiated from the remaining congeners by a combination of the following characters: size moderate (SVL 61.0–77.1 mm); nares bordered with rostral; internasals absent; postmentals enlarged; interorbital scales between anterior corners of the eyes 28–30; dorsal tubercles absent; ventral scales between mental and cloacal slit 175–185; midbody scale rows 123–140; ventral scale rows 38–40; subdigital lamellae on first toes 13–15, on fourth toes 14–16; finger and toe webbing present at base; tubercles on dorsal surface of fore and hind limbs absent; precloacal pores six (3+3 or 5+1) in a discontinuous row in males, absent in the female; postcloacal tubercles 1 or 2; tubercles absent on dorsal surface of tail base; subcaudals distinctly enlarged; dorsal surface of body with greyish brown blotches. Molecular analyses demonstrated the new species is closely related to G. bonkowskii and G. thakhekensis, but separated from them by approximately 7% in genetic divergence as shown by a fragment of the mitochondrial ND2 gene.

A New Species

Two species of Bush Vipers, genus Atheris Cope, 1862, have been reported for the continental island of Bioko, Gulf of Guinea – Atheris squamigera and a putatively undescribed species, morphologically similar to Atheris chlorechis. The latter was only known from one specimen collected in the early 1900s and its taxonomic identity has never been fully resolved. Based on recently collected specimens of Atheris from Bioko Island, we reviewed all the available data and specimens through detailed morphological comparisons against all known species of the genus. Our results confirm that Atheris squamigera is present in Bioko Island, and that the second taxon is a new species, which we describe here as Atheris hetfieldi sp. nov. The newly described species presents a series of morphological characters that clearly differentiate it from all of its congeners. The description of this new species is the first of a new snake species from Bioko in more than 100 years and this species is the only snake currently recognized as endemic to the island.

A new gall wasp species, Plagiotrochus hepingensis sp. n. is described from Hunan Province, China that forms integral galls on the central vein on the abaxial leaf blade surface of Quercus (Cyclobalanopsis) glauca (Fagaceae). The morphological characters of the new species are described and photographed and data on the diagnosis, distribution, and biology are given. Additionally, a specific region of the COI gene was amplified using the primers HCO-2198 and LCO-1490 and compared for both the new species and Plagiotrochus masudai Ide, Wachi & Abe.

A New Species

A new species of Pareas is described from Yunnan Province, China, based on morphological comparisons and molecular data. Genetically, the new species is most closely related to the recently-described Pareas geminatus, for which we present new topotypic findings. The genetic divergence (uncorrected p-distance) of the cytb gene between the new species and congeners ranged from 6.14% to 24.68%. Morphologically, the new species can be distinguished from P. geminatus and all other congeners. Our work brings the total number of species within the genus Pareas to 22.

A New Species

We describe a new species of Megophryidae frog, Megophrys shunhuangensis sp. nov., from Hunan Province, Southern China. It can be distinguished from other known species in the subgenus Panophrys by morphological characters, bioacoustic data and a molecular divergence in the mitochondrial 16S rRNA gene similar to that found among other species of Panophrys. M. shunhuangensis sp. nov. is characterized by a relatively small body size, with adult females measuring 37.6 mm and adult males measuring 30.3–33.6 mm in snout to vent length; maxillary teeth present, vomerine teeth absent; tongue smooth, not notched behind; hindlimb slender, heels overlapping, tibio-tarsal articulation reaches forward between the nasal and tip of snout. Molecular phylogenetic analyses also show that M. sp. 6 from (Mao’er Shan, China) from Chen et al. (2017) and M. sp. 24 (Anjiangping and Mao’er Shan, China) from Liu et al. (2018) may be the same species as M. shunhuangensis sp. nov., we consequently speculate that the new species also distributed in Anjiangping and Mao’er Shan, China. At present, the genus Megophrys contains 85 species of which 48 species are distributed in China, and 30 belong to the subgenus Panophrys.

A New Species

Abstract—Justicia rubrobracteata, a new species from northeastern Brazil, is described and illustrated. The new species is morphologically similar to J. aequilabris due to its shrubby habit, and terminal and axillary spicate inflorescences with red flowers. However, J. rubrobracteata is differentiated mainly by the shape and color of its bracts and bracteoles as well as an orangish macula in the corolla, and a torulose capsule. In addition, J. rubrobracteata is only known from northeastern Brazil, from the states of Paraíba and Rio Grande do Norte, while J. aequilabris is widely distributed in Bolivia, Brazil, and Paraguay. A table with the main morphological characters of both species is included, as well as photographs, a key to species of Justicia for the states of Paraíba and Rio Grande do Norte in northeastern Brazil, a distribution map of both species, and conservation data for the new species.

Unusual Finding

A new species of Pogonophora obtained from one station at a depth of 25 m from near the Dikson Island in the Kara Sea is described. Galathealinum karaense sp. nov. is one of the largest pogonophorans, the first known representative of the rare genus Galathealinum Kirkegaard, 1956 in the Eurasian part of the Arctic Ocean and a highly unusual finding for the desalted shallow of the Yenisey Gulf. Several characters occurring in the new species are rare or unique among the congeners: under-developed, hardly discernible frills on the tube segments, extremely thin felted fibres in the external layer of the tube, and very faintly separated papillae in the anterior part of the trunk. Morphological characters useful in distinguishing species within the genus Galathealinum are defined and summarised in a table. Diagnosis of the genus Galathealinum is emended and supplemented by new characters. Additionally, three taxonomic keys are provided to the species of Galathealinum and to the known species of the Arctic pogonophorans using either animals or their empty tubes only, with the brief zoogeographical information on each Arctic species.

Two braconid genera from the subfamily Alysiinae, Lodbrokia Hedqvist, 1962 and Asyntactus Marshall, 1898, are recorded in the fauna of Russia and in the Asian continent for the first time. A new species Lodbrokia uralica sp. nov. is described from the Urals, and a key to species of this genus is provided. Redescriptions of the female and male of Asyntactus rhogaleus Marshall, 1898 with information about the level of variability of its morphological characters are given. Asyntactus sigalphoides Marshall, 1898 is synonymised with A. rhogaleus Marshall, 1898 (syn. nov.).

Scrophularia dianatnejadii Ranjbar & Rahchamani, a new species from Tehran Province in northern Iran, is described and illustrated. It is closely related to S. amplexicaulis Benth. and shares with it some diagnostic morphological characters such as habit, plant indument, phyllotaxy, and corolla shape and color. Both species are placed in Scrophularia L. sect. Mimulopsis Boiss. Macro- and micromorphological characters of the two are examined and compared. Pollen morphology of these species is investigated using SEM. Detailed descriptions, illustrations, distribution maps, and conservation status of both species are provided.
