A new Chinese species, Crossodonthina choui, from Hunan Province is described. The new species can be separated from all known species by having a unique mandible and s-setae formula. The mandible consists of 5 branches and 3 basal teeth (one tooth is finger-like). The s-setae formula of the new species is 2+ms, 2/1, l, 1,2,1.展开更多
