Two new species of the genus Paracyatholaimus Micoletzky (Nematoda: Cyatholaimidae) from the Yellow Sea

Two new free-living marine nematode species of Paracyatholaimus Micoletzky, 1923 Paracyatholaimus qingdaoensis sp. nov. and Paracyatholaimus huanghaiensis sp. nov. from the Yellow Sea, China are described. Paracyatholaimus qingdaoensis sp. nov. is characterized by cylindrical body with conical tail; spicules reverse S-shaped, distally pointed; gubernaculum plate, with two cusps at distal end, parallel to the spicules; 10 thick setose precloacal supplements in a 5 + 5 arrangement, anterior group of five supplements located at a protuberance. Paracyatholaimus huanghaiensis sp. nov. is characterized by a cylindrical body with conic-cylindrical tail; slender spicules curved, distally pointed; gubernaculum handle-shaped, expanding distally to a plate, with some sawteeth at distal end; three papillose precloacal supplements, each papilla protruding conically with cuticularized narrow ducts. A key for identification of species of Paracyatholaimus is proposed. http://www.zoobank.org/urn:lsid:zoobank.org:pub:0A8E40E5-AE7A-47DA-B755-61E1D088C1E9     

Two new species of the genus Sinella Brook, 1882 (Collembola: Entomobryidae) from East China

Two new species, Sinella hexaseta sp. nov. and Sinella pauciseta sp. nov., collected from East China, Anhui and Zhejiang provinces, respectively, were described. Both are easily discriminated from each other and all known Sinella species by their unique dorsocentral chaetotaxic patterns on Abd. IV. In S. pauciseta sp. nov., postlabial setae H_1–4 are ciliate, which are smooth in all other known species of the genus.     

A new species of the genus Zhangixalus (Amphibia: Rhacophoridae) from Vietnam

ABSTRACT

A new rhacophorid species is described from Vietnam on the basis of nine specimens collected in Quan Ba District, Ha Giang Province, northeastern Vietnam. The new species is morphologically similar to Zhangixalus pinglongensis, Z. dorsoviridis, and Z. nigropunctatus, however, it differs from the latter by having the flank cream with large black blotches on axilla and groin. The genetic distance between the new species and Zhangixalus pinglongensis, Z. dorsoviridis and Z. nigropunctatus is >3.57% (16S mtDNA gene fragment). Zhangixalus jodiae sp. nov. can be distinguished from all other species of Zhangixalus and other small rhacophorid species from Southeast Asia by a combination of the following characters: size small (SVL 36.1–39.8 mm in males); head as long as wide; vomerine teeth present; dorsal surface of head and body green without spots; axilla cream with large black blotches, groin and front-rear parts of the thigh, ventral surface of tibia black with orange blotches; lower jaw region greyish, chest and belly cream.

Three new species and one new record of the genus Doryphoribius Pilato, 1969 (Tardigrada: Eutardigrada: Hypsibiidae) from the Great Smoky Mountains National Park (Tennessee,USA)

Box jellyfishes (Cnidaria: Cubozoa) have a profound impact on human activities because of their highly potent venoms that may lead to severe envenomations in humans. Cubozoa is one of the smallest classes within Cnidaria with only some 50 described species in seven families. The literature on Cubozoa is scattered and oftentimes difficult to access. In particular, comprehensive treatments of Cubozoa that present a comparative overview of the group are either non-existent or largely outdated. Here we provide a synopsis of the carybdeid Cubozoa (Carybdeida) including an illustrated key to the families and genera of this order. Of particular interest is the family Carukiidae, which contains the species that was originally attributed with causing a severe envenomation syndrome called Irukandji syndrome. One new species of Carukiidae, Malo filipina sp. nov., is described, Morbakka virulenta is redescribed and a neotype is designated, and an unidentified species of Morbakka is recorded from the Philippines.     

A taxonomic review of the genus Nippoptilia (Lepidoptera: Pterophoridae) from Korea,with description of a new species

In the present study, we review the genus Nippoptilia of Korea. In total, four species are recognized, including a new species, Nippoptilia distigmata sp. nov., and two new records, Nippoptilia cinctipedalis (Walker) and N. issikii Yano, for Korea. All the available information, such as distributional ranges and biology of each taxon, is provided. The keys to the genus Nippoptilia in Korea are provided, along with illustrations of external and genitalic characteristics.     

A new genus and species of terrestrial isopod from Malaysia (Crustacea,Oniscidea, Platyarthridae)

A new terrestrial isopod, Cephaloniscus sociabilis gen. nov., sp. nov., from Fraser Hill in central Malaysia, is described and illustrated. The new genus belongs to the family Platyarthridae and is distinguished from other members of the family by the characteristic structure of the cephalon. The specimens were collected from the nest of the termite Hospitalitermes sp. (near medioflavus Holmgren) together with the ant Centromyrmex hamulatus (Karavaiev).     

A new genus and two new species of Parastenocarididae (Copepoda: Harpacticoida) from southeastern India

Indocaris gen. nov. with two new species, Indocaris imbricata sp. nov. and Indocaris inopinata sp. nov., and also for the already known Indocaris tirupatiensis (Ranga Reddy 2011a) comb. nov. – all from the groundwaters in peninsular India. The highly diagnostic synapomorphy of the new genus is a composite character associated with the male leg 4 basis: five or six prominent, imbricate, enlarged, petal-like spinules, arranged as a semi-whorl at the insertion of the endopod and increasing in size from internal to external. Another distinctive feature of the same appendage is that its one-segmented endopod is dilated or bulbous in the proximal half, produced distally into an incurved spiniform or horn-like structure about as long as the corresponding first exopodal segment, and ornamented with three or four fine spinules on the subproximal outer margin. The three species also share a unique constellation of other salient morphologic features, which along with the phylogenetic position of Indocaris gen. nov. within the family Parastenocarididae are discussed. Indocaris gen. nov. has closest phylogenetic affinity with the Neotropical Remaneicari Jakobi, 1972. A short note on the ecology and biogeography of the parastenocaridid species of the Indian subcontinent is provided besides a key for their identification.     

A new species of the genus Liopeltis Fitzinger, 1843 from Vietnam (Squamata: Colubridae)

ABSTRACT

A new species of Liopeltis from central Vietnam is described based on morphological and molecular differences. Liopeltis pallidonuchalis sp. nov. is distinguished from its congeners by a combination of the following characters: one single (or missing) loreal; one single nasal shield; dorsal scales in 15–15-15 rows, all smooth; 1 preocular, 2 postoculars and 1 + 2 temporals; 7 supralabials, of which 3^rd and 4^th in contact with the eye; 8 infralabials; nasal contacting internasal; prefrontal touching or separated from supralabials; ventral scales 126–138; subcaudal scales 67–73, paired; relative tail length about 0.274–0.301; an uniform bronze body colouration; a thin postocular stripe extending from eye to end of the neck becoming indistinct posteriorly. The new species differs from the morphologically closest species Liopeltis frenata by the lower number of ventrals and subcaudals, by characteristic colouration and significant divergence in cytochrome b mtDNA gene sequences (p = 15.3–15.6%). The new species is currently known from northen and central parts of the Annamite (Truong Son) Mountains, central Vietnam, and was recorded from montane evergreen tropical forests of Kon Tum–Gia Lai Plateau (Gia Lai and Thua Thien–Hue provinces, Da Nang City) at elevations of 950–1010 m asl to karst tropical forests in Quang Binh Province in the north at elevation 150 asl. We suggest the new species should be considered as Vulnerable (VU) following the IUCN’s Red List categories. An updated taxonomic key to the Liopeltis species is provided.     

A new species of Friesea (Collembola: Neanuridae) from the Antarctic Continent

A new species of Friesea was found in East Antarctica and is described here as Friesea eureka sp. nov. This is the first new collembolan species to be described from the Antarctic continent in 30 years, even though ice-free areas have been intensively surveyed over that time. It brings to five the number of described species of the genus Friesea known from the Antarctic continent and Peninsula, so is the most speciose genus of Collembola in the region. However, one of these, F. grisea Schäffer, comprises a number of cryptic species of different molecular lineages. The new species is distinguished by having 4 + 4 ocelli plus 1 + 1 hardly visible, a very reduced furca, up to four or five faintly clavate tenent hairs, four anal spines and four spinose chaetae in adult. The restricted distribution of the species emphasises the importance of protecting ice-free areas on the continent as they often contain at least one locally endemic faunal species

New species and rediagnosis of Coecobrya (Collembola: Entomobryidae), with a key to the species of the genus

The history of Coecobrya is traced and the genus is redefined. Two new species are described and one known species is redescribed in this paper: Coecobrya lanna sp. nov., Coecobrya tukmeas sp. nov. and Coecobrya aokii (Yoshii, 1995 Yoshii, R. 1995. Notes on Collembola of Vanuatu. Acta Zool Asiae-Orient., 3: 43–50.  [Google Scholar]). Additional details are provided for three other species Coecobrya guanophila Deharveng, 1990 Deharveng, L. 1990. Fauna of Thai caves. II. New Entomobryioidea Collembola from Chiang Dao cave, Thailand. Occas Papers Bernice P Bishop Mus., 30: 279–287.  [Google Scholar], Coecobrya similis Deharveng, 1990 Deharveng, L. 1990. Fauna of Thai caves. II. New Entomobryioidea Collembola from Chiang Dao cave, Thailand. Occas Papers Bernice P Bishop Mus., 30: 279–287.  [Google Scholar] and Coecobrya tenebricosa (Folsom, 1902). Complete S-chaetotaxy of the dorsal tergites is illustrated for the first time in the genus. Sinella ciliata Denis, 1932 is synonymized with C. tenebricosa. A key to the world species of Coecobrya is given.     

A new shield-bug species Piezodorus grossi (Het.: Pentatomidae) from the Australasian region previously confused with P. hybneri (Gmelin)

Material previously identified as Piezodorus hybneri (Gmelin) from the Australasian region is here described as a new species, P. grossi sp. nov. The two species can be distinguished on the basis of the aedeagus in the male and spermathecal proximal duct in the female.     

First record of the genus Koreanurina Najt and Weiner (Collembola: Neanuridae: Pseudachorutinae) from China,with description of two new species from Changbai mountain

The genus Koreanurina Najt and Weiner, 1992 is recorded for the first time from China. It is redefined and its similarity with the subfamily Caputanurininae is stressed. Two species are described from Changbai Mountain in North-East China: Koreanurina weinerae sp. nov. and K. alba sp. nov. The first species differs from the other species of the genus, mostly by its post-antennal organ located on the lateral edge of head (versus dorsolaterally), its central plate on head wider and the presence of only 1 + 1 chaetae on Th I (versus 2–3 + 2–3). K. alba sp. nov. differs from the other species of the genus mostly by the absence of body pigment, and the presence of only 1 + 1 chaetae posteriorly to the furcal rest (versus 2 + 2).

A new and enigmatic representative of Leucocythere Kaufmann, 1892 from the Eastern Cape Province (South Africa) (Crustacea,Ostracoda)

Leucocythere helenae sp. nov. is described from a small, semi-permanent dam near Grahamstown (RSA). It belongs to Leucocythere s.s., but is at the same time characterized by a number of aberrant features, especially the shape and size of the large copulatory process on the hemipenis and the relatively short setae on the P(3) of the male. A cladistic analysis is conducted and it appears that within Leucocythere, the African species have the most plesiomorphic character states. The discovery of L. helenae sp. nov. in South Africa furthermore falsifies previous hypotheses on the age and origin of the Leucocytherini in general and Leucocythere s.s. in particular. It should now be accepted that the latter genus is not of Pleistocene age, but much older, although the lack of fossil material prevents more exact dating. Also, when the cladogram is studied in conjunction with the present day distribution map of Leucocythere, the concept of a Palaearctic origin of this genus must be rejected. The most plausible hypothesis to date on the origin of this group appears to be a generalized distribution of a leucocytherid ancestor over Europe, Asia and Africa (at least), with subsequent speciation through vicariance.     

Two new species of Pogonognathellus (Collembola: Tomoceridae) from China,with a discussion of East Asian species

Thirteen species of the genus Pogonognathellus Paclt, 1944 Paclt, J. 1944. Nomina nova in Collembola. Entomol Listy, 7: 92 [Google Scholar] have been reported worldwide, two from East Asia. Two new species of the genus from Jilin Province, northeast China are described here. Pogonognathellus heterochros sp. nov. is characterized by its unique body colour. Pogonognathellus mai sp. nov. is most similar to Pogonognathellus beckeri (Börner, 1909) but differs from it mainly in maxilla and tenaculum. A key to the East Asian species is provided, and the confusion among these species is discussed. http://www.zoobank.org/urn:lsid:zoobank.org:pub:902CD044-0A58-4CCF-A1B1-449C9DE10938     

A new pontoniine shrimp genus (Crustacea: Decapoda) from the Yemen,with a note on other species

An unusual new genus and species of coral inhabiting pontoniine shrimp from the Yemen is described and illustrated. The new shrimp is remarkable for its very small size and the unique form of its telson. Three other pontoniine shrimps are also reported from the Yemen for the first time, raising the number of such shrimp species known from southern Arabia to 18.     

A new species of Kurixalus (Anura: Rhacophoridae) from northern Vietnam with comments on the biogeography of the genus

ABSTRACT

We describe a new species of rhacophorid frogs from Nghe An Province in northern Vietnam based on morphological and molecular evidences. Morphologically, Kurixalus gracilloides sp. nov. is distinguished from its congeners by a combination of the following diagnostic characters: body size small (snout–vent length 27.9–31.2 mm in males); head width subequal to head length; snout rounded with no dermal projection; canthus rostralis distinct, curved; vomerine teeth present; single internal vocal sac; iris golden-brown; small nuptial pad in finger I; dorsal surfaces golden-brown with a saddle-shaped dark marking; large dark spots on ventral surfaces absent; dermal fringes along outer edge of limbs; conical dermal appendage at the heel; skin on dorsum rough; skin on throat and chest granular; finger webbing rudimentary and toe webbing moderately developed, webbing formula I 2–2½ II 1½–3 III 1¾–3½ IV 3–1½ V. The new species is separated from all other congeners by uncorrected genetic distances ranging from 5.4% to 12.7% based on mitochondrial 16S rRNA gene. Phylogenetic analyses of mtDNA suggest that the new species is nested within a clade of Taiwanese and Yunnan Kurixalus with strong support values. The new species is currently known only from secondary bamboo forest in Pu Mat National Park, northern Vietnam, at elevations of 150 m asl. We suggest the new species should be considered as Near Threatened (NT) following the IUCN’s Red List categories.

A new genus with three new species of copepods from the family Diaixidae (Crustacea: Calanoida), and a redefinition of the family

Plankton samples taken in the Gulf of Carpentaria, Australia, yielded material of a new genus containing 3 new species: Anawekia spinosa gen. nov. et sp. nov., A. robusta sp. nov. and A. bilobata sp. nov., which are described herein. The family Diaixidae now contains 12 described species in 2 genera, 9 being in the genus Diaixis. It is noted that 3 of the Diaixis species (including the type species) share some features which are not shared with the remaining 6 species, and that these latter species should probably be placed into a third genus. An amplified redefinition of the family is given.     

Two new free-living nematode species of Setosabatieria (Comesomatidea) from the East China Sea and the Chukchi Sea

Two new free-living marine nematode species of the genus Setosabatieria from the sandy intertidal zone of Xiamen, in the East China Sea and a shallow water area in the Chukchi Sea, Arctic Ocean are described and illustrated. Setosabatieria longiapophysis sp. nov. is characterized by four longitudinal files with 7–9 cervical setae per file, 15–16 minute papillate precloacal supplements and relatively long straight apophyses of gubernaculum. Setosabatieria major sp. nov. is identified by its relatively large body of 2701–3144 µm, the number (10–11) of cervical setae per file, 26–28 minute papillate precloacal supplements and spicules with a central septum at both the proximal and distal end. A pictorial identification key to all known species of Setosabatieria is provided.
