A new species of Dicranocentrus Schott from Hainan (China) with a key to the Chinese species of the genus (Collembola, Entomobryidae).

ABSTRACT: A new species, Dicranocentrus hainanicus Ren & Zhang, sp. n., is described from Hainan Province, China. Complete tergal chaetotaxy including microchaetae is illustrated and discussed. It is characterized by having the dental spines arranged in 2-3 rows, two inner teeth on unguis, 5, 2, 2 central macrochaetae on Abd. I-III, two inner S-chaetae on Abd. V displaced anteriorly, and the additional microchaetae associated with the S-chaeta acc.p6 on Th. II-Abd. II. It is most similar to D. chenae Ma, Chen & Soto-Adames but differs from the latter in the number and arrangement of dental spines and the absence of macrochaeta Pa1 on dorsal head. A key to the Chinese species of the genus is provided.

Two new species of Coecobrya (Collembola, Entomobryidae) from China, with an updated key to the Chinese species of the genus.

Project description:Two new Coecobrya species, which were newly collected in 2014, are described from China. Coecobryasanmingensis sp. n. from southeast China (Fujian) is the fourth 1+1 eyed species in the genus; it can be distinguished from other three species by the ciliate chaetae X and X2-4 on the ventral side of head, the abundant chaetae on the trochanteral organ, a large outer tooth on the unguiculus, the absence of smooth manubrial chaetae, and the dorsal chaetotaxy. Coecobryaqinae sp. n. from southwest China (Yunnan) is characterized by paddle-like S-chaetae of Ant. III organ, ciliate chaetae X, X2 and X4 posterior to labium, medial macrochaetae on the mesothorax, and 5+5 central and 2+2 lateral macrochaetae on the fourth abdominal segment. An updated key to the Chinese species of Coecobrya is given.

Two new species of Sinella from Guangdong Province, China (Collembola: Entomobryidae).

Project description:Two new blind species of Sinella are described from Guangdong Province, China. Sinella colubra sp. n. possesses minute smooth postlabial chaetae, long mucronal spine, and 4+4(5) lateral mac on Abd. IV, and can be distinguished from two closely related species by the postlabial chaetae and the dorsal macrochaetotaxy. Sinella zhangi sp. n. is also described and can be diagnosed by having minute labial chaeta r and postlabial chaetae X and X4, 5+5 mac on Abd. I, 4+4 central mac on Abd. II, and 4+4 central and 5+5 lateral mac on Abd. IV.

New blind species and new records of Sinella from Nanjing, China (Collembola, Entomobryidae).

Project description:Two new blind species of Sinella are described from Nanjing, China. Sinella quinseta sp. n. from Purple Mountain possesses unique 5+5 central macrochaetae on Abd. II, and can be distinguished from other species of the genus by the postlabial chaetae and the dorsal chaetotaxy. Sinella qixiaensis sp. n. from Qixia Mountain is characterized by the paddle-like S-chaetae of Ant. III organ and the smooth straight chaetae on the manubrium and base of dens; it differs from two closely related species by the smooth manubrial chaetae, the labial chaetae, the Ant. III organ, and the macrochaetae on Abd. II. Sinella fuyanensis Chen & Christiansen and Sinella quinocula Chen & Christiansen were also newly recorded from Nanjing.

A new species of Dicranocentrus (Collembola, Entomobryidae) from China with comments on the systematic position of the genus.

Project description:Dicranocentrus liuae sp. n. is described from the northern subtropical region of China. The new species is most similar to D. wangi Ma & Chen, 2007, but differs from it in the relatively shorter Ant. V, the 1+1 central macrochaetae on Abd. III, the number of chaetae on tenaculum, and the absence of dental spines. The systematic position of Dicranocentrus is also discussed. Present evidence, particularly S-chaetotaxy, indicates that the genus is closer to Heteromurus than to the unscaled species of Orchesella and Orchesellides.

Two new ant species of the genus Leptogenys (Hymenoptera, Formicidae) from Hainan, China, with a key to the known Chinese species.

Project description:Two new species of ponerine ants from Hainan Province, China, Leptogenyshainanensissp. nov. and L.zhouisp. nov., are delineated and depicted based on the worker caste. Leptogenyshainanensissp. nov. belongs to the L.leleji species group, with mandibles elongate, slender and curved, lacking a distinct masticatory margin. On the other hand, L.zhouisp. nov. belongs to the L.crassicornis species group, distinguished by its square head, smooth body, mandibles with a dentate masticatory margin, and short antennae. A key to workers for the known species of Leptogenys in China are provided and a map is provided for the newly described species.

New species of Homidia (Collembola, Entomobryidae) from eastern China with description of the first instar larvae.

Project description:Morphology of the first instar larvae of Collembola has considerably taxonomical and phylogenetic significance. We describe the first instar larvae for the first time in Homidia. External morphology of first instar larvae and adults of Homidia jordanai sp. n. is described based on observations under light and scanning electron microscopes. Most organs of adults bear considerably more setae than the first instar larvae; in addition, first instar larval Homidia lack labial seta R, seta on tenaculum, mucronal spine, and dental spines. The new species is characterized by weakly pigmented body, long antennae subequal to body in length, 1+1 inner macrochaetae on Abd. III, few inner macrochaetae on posterior Abd. IV, and spiny and short seta pi on dental base. Differences between new species and other two similar ones, taxonomical significance of the first instar larvae and the position of Homidia are also discussed.
