Abstract
The genus Allonychiurus Yoshii, 1995 is briefly introduced and a new Chinese species, Allonychiurus megasomus sp. nov., from Jiangsu Province, is described. The new species is diagnosed as having 32/133/33343 dorsal pso, 11/000/ 01110 ventral pso, 0/000/10000 ventral parapseudocelli (psx), 2/012/22222 dorsal sensilla, PAO consisting of 18–22 compound vesicles, Abd. IV with median setae a 0 and p 0 , Abd. V with m 0 , tibiotarsus with 11 setae in the distal whorl, unguiculus without basal lamella and ventral tube with 8+8 setae. It is easily separated from other known species in the genus by the combination of above characters. The status of the species in the genus is discussed.References
