A Review of the Genus Homidia (Collembola, Entomobryidae) in China Informed by COI DNA Barcoding, with the Description of Three New Species

The genus Homidia contains 84 species of which 60 have been reported from China. The sequence of COI for ten Homidia species are provided and a neighbour-joining tree is presented. Three new species of Homidia are described from Chongqing Municipality, China. Homidia wuxiensis sp. nov. is characterised by its colour pattern and chaetotaxy of Abd. IV; Homidia pseudochroma sp. nov. by some expanded post-labial chaetae and chaetotaxy of dorsal head and Abd. II–IV and Homidia yangi sp. nov. by its colour pattern. Based on similarities in COI sequences and morphology, we designate Homidia linhaiensis (Shi, Pan & Qi), as a junior synonym of Homidia tiantaiensis (Chen & Li).
