The fifth species in the genus Lepidodens was reported from Wuyanling National Natural Reserve.Lepidodens taishunensis Lin,Wu&Pan sp.nov.is the second new species of this genus recorded from Zhejiang Province.This new species could be discriminated from others species in this genus by colour pattern,labial chaetae E and R ciliated,dorsal Abd.Ⅰ–Ⅲand centrodorsal Abd.Ⅳwith 2/4/7/8 macrochaetae.A detailed comparison among the five Lepidodens species,dorsal body chaetotaxy of larvae and key to species of the genus were provided.

A new species,Lepidodens huadingensis Guo&Pan sp.nov.,was collected from Zhejiang Province.This is the most northern record of a species in this genus.This new species is identified by a narrow longitudinal stripe on lateral side from head to thoracic segment Ⅲ,a labial chaetal formula of M_(1)M_(2)R(R_(2))EL_(1)L_(2),dorsal abdominal segments Ⅰ-Ⅲ with 3/6/7 mac,and two smooth chaetae on posterior face of ventral tube.A detailed comparison among four recorded species,a key to species of this genus were provided.
Highly diversified colorations among springtails (Collembola) have been widely used for species diagnosis, but their phylogenetic significance is poorly known. We addressed this issue in the largest Entomobryinae genus Entomobrya, which possesses variable color patterns among species. The relationships within the genus and to other genera have also rarely been studied. Based on material mainly from China, we have conducted a multilocus phylogeny and topology tests with likelihood and Bayesian algorithms, and accordingly demonstrated the non-monophyly of Chinese Entomobrya. The division of five clades, including Entomobrya and several related genera, coincided well with five types of colorations, respectively. Further analyses of divergence time and historical biogeography revealed that Chinese Entomobrya originated mainly from Palearctic (northern and western) China in the Paleocene and Eocene. This study highlights the great phylo? genetic values as well as taxonomic uses of coloration in Chinese Entomobrya. Multiple phylogenetic and biogeographic origins of Entomobrya imply its complicated relationships with both scaled and unsealed genera of Entomobryinae.
A new species with four macrochaetae in the ＂eyebrow＂ of the anterior dorsal abdominal segment Ⅳ （Abd.Ⅳ）, Homidia quadriseta Pan sp. nov. is described fi＇om Zhejiang Province, eastern China. It can be discriminated from other recorded species in this genus by entire Abd. Ⅲ and posterior half Abd. IV darkly pigmented, 1 macrochaetae on medial Abd. Ⅲ, 2＋2 macrochaetae in ＂eyebrow＂ on anterior Abd. Ⅳ and 3 macrochaetae on posterior central Abd. Ⅳ, clypens with 12 chaetae, and fewer dental spines （7-8） on basal internal denes and with most spines slightly ciliated. Also, the chaetotaxy of the first instar of this new species is provided here.
A new blind species of the genus Sinella Brook, Sinella bui sp. nov., is described from Gutian Mountain, Zhejiang Province, China. It is characterized by eyes absent, labial chaeta R ciliate, 4＋4 central and 6＋6 lateral macrochaetae on the fourth abdominal segment. It is most similar to Sinella christianseni Ma Chen but differs from the latter in ciliate labial chaeta R, pointed tenent hairs, and abdominal chaetotaxy.
A new species, Homidia xianjuensis sp. nov. from eastern China, was described. It can be identified by head dark including ventral side, except ＂Y＂-shape unpigmented patch on dorsal central head, one interrupted stripe on each sub-lateral thorax to abdominal segment I, chaetotaxy of labium and abdominal segment I and IV–V. Illustrations of the second instar larvae of this new species were also provided.
A blind new species of springtail, Coecobrya islandica Shi ＆ Pan sp. nov., is described from Dongtou Island. It is identified by eyes absent, ＂smooth＂ chaetae present on manubrium and absent on inner tibiotarsus, labial ehaetae MREL1L2 smooth, spiny mic X and X4 present, clypeal chaetae, sens on Abd. II-IV and dorsal chaetotaxy ofTh. II-Abd. V, and is most similar to Coecobrya brevis Xu et al., 2012. Illustrations and detailed differences between similar species are provided here.
Homidia triangulimacula sp. nov. is described from Tiantong National Forest Park, Zhejiang Province. It can be easily discriminated from other species of Homidia by triangular dark patch on dorsal central mesothorax, labial chaeta M replicated and labial basal and posterior labial chaetae expanded, 6＋6 macrochaetae on posterior abdominal segment IV, and middle S-chaeta posterior to macrochaeta m3 on abdominal segment V. A detailed morphological character comparison and a key to species with chaetae expanded on labium or posterior labium in Homidia are provided here.
In this paper, an eyed new species of genus Sinella is described. It is identified by 2＋2 ommatidia transverse arranged, dorsal body（except Abd. Ⅴ-Ⅵ ） scattered with brown spots, mac a2 present on Abd. Ⅱ, 3 mac on central and 5 on lateral of Abd. Ⅳ. Illustrations and detailed differences between 2＋2 ommatidia transverse arranged species are provided.
Anew species Homidiapseudosinensis sp. nov. from southeast China is described. This new species can be easily identified by posterior Th. II with a roughly M-shaped transverse band, labial setae and chaetotaxy of Abd. IV. Illustrations and a key to species of this genus from Fujian Province are provided.
