One new species of the genus Homidia(Collembola:Entomobryidae) from Zhejiang Province,with a description of the second instar larvae

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.

The most northern distribution record of the genus Lepidodens (Collembola:Entomobryidae) with description of a new species from Zhejiang Province

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.

Description of a new species and the first instar larvae of Homidia(Collembola:Entomobryidae) from Taizhou,Zhejiang Province

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.

Molecular phylogeny of Entomobrya (Collembola: Entomobryidae) from China: Color pattern groups and multiple origins

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.
