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.

Two new palaemonid shrimps (Crustacea: Decapoda) from the Australian North West Shelf

Two palaemonid shrimps, from about 80 and 50 m on the Australian North West Shelf, are described and illustrated. A new genus, Carinopontonia, is designated for the single incomplete specimen of C. paucipes sp. nov. The new genus is most closely related to the genus Dasycaris Kemp, 1922. A single specimen of a second shrimp can be referred to Apopontonia Bruce, 1977, but to neither of the known species, and it is now described as A. tridentata sp. nov.     

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     

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.

The West Palaearctic species of Fidiobia Ashmead, 1894 (Hymenoptera: Platygastroidea)

One new genus Songmachilis and six new species in family Machilidae are described from China: Songmachilis xinxiangensis gen. sp. nov., Coreamachilis songi sp. nov., Pedetontinus jiuzhaiensis sp. nov., Pedetontinus maijiensis sp. nov., Pedetontinus taishanensis sp. nov. and. Pedetontinus wudangensis sp. nov. A key to all Chinese species of Pedetontinus is given. We also examined the relationships among Chinese machilids based on partial sequences of mitochondrial cytochrome c oxidase subunit I (COI). The molecular study further supported the species status of the six new taxa.     

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

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.     

New taxa of the family Trochometridiidae (Acari: Heterostigmata) associated with insects from Iran

A new genus and two new species of mites of the family Trochometridiidae (Acari: Heterostigmata) are described from Iran: Neotrochometridium sensillum Hajiqanbar and Khaustov gen. nov., sp. nov. associated with two carabid beetles and Trochometridium iranicum Hajiqanbar and Khaustov sp. nov. associated with a halictid bee. We also present the first report of two previously described species. These findings provide the first record of the family Trochometridiidae from Iran. The chaetotaxy of tarsus I of the family is discussed and a key to world genera and species is provided.     

Description of a new Tetranychus (Acarina,Prostigmata: Tetranychidae) pest of Musa from French Guiana

A new species of tetranychid mite, genus Tetranychus Dufour, 1832, is described and illustrated herein from neotropical area. Tetranychus musae sp. nov. (Acari, Prostigmata: Tetranychidae) differs from other species in the genus by the combination between the arrangement of leg setae on females tarsus I and the shape of the aedeagus. Tarsus I bears one tactile setae proximal to proximal duplex setae and three tactiles in line or almost in line with proximal duplex setae. The aedeagus knob consists of an acute posterior projection bent ventrally and a larger anterior rounded projection directed anterodorsally. T. musae specimens were collected in French Guiana where they appeared to be a pest of Musa sp. A key to adults of neotropical species of the genus Tetranychus feeding on banana is provided.     

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.

Plantes Cryptogames de France. Par I. B. H. I. Desmazières. Fasc. XVII. Lille, 1836

Summary

A new genus and species of pilargid polychaete, Litocorsa stremma, is described from silty grounds on the west coast of Scotland. Its relationship to other pilargid genera is discussed. Notes on two other pilargid species and a revised key to the genera of the Pilargidae are given.     

A new pontoniine shrimp (Crustacea: Decapoda: Palaemonidae) from the Ryukyu Islands,Japan

An unusual new genus and species of pontoniine shrimp, Nippontonia minirostris gen. nov., sp. nov., from a sponge host from the Ryukyu Is., Japan, is described and illustrated. The new genus appears not to be closely related to any of the previously described genera. The genus is particularly remarkable for the morphology of the fixed finger of the minor second pereiopod, which is without parallel in the Palaemonidae.     

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.
