Platocoelotes Wang, 2002

Platocoelotes Wang, 2002: 119 (type species, by original designation, Coelotes impletus Peng and Wang, 1997 from China; Wang, 2003: 561, Figs. 75, 78; Xu and Li, 2008: 86; Liu and Li, 2008: 49 )

Diagnosis: Males of Platocoelotes are similar to that of Femoracoelotes , Leptocoelotes and Spiricoelotes in lacking median apophysis, but can be distinguished from Femoracoelotes by lacking femoral apophysis, and from Leptocoelotes and Spiricoelotes by the presence of conductor dorsal apophysis. Males of Platocoelotes can also be distinguished from any other Coelotinae genera by the presence of ventral conductor apophysis ( Figs 1B–C , 2B–C , 3B–D , 4C–D ). Females can be distinguished by a combination of the following characters: epigynal teeth absent, epigynal hood distinct, atrium shallow and broad ( Figs 1F , 3F , 4F ; Figs 1E , 2D , 3E , 4D in Liu & Li 2008; Figs 6, 8, 15, 21 in Xu & Li 2008).

Distribution: Central and southwest China (Guangxi, Guizhou, Hubei, Hunan, Sichuan).
