Diagnosis.

Head with no projection on vertex, leg-pair 7 with a long subfalcate mesal process and a broader triangular one on coxa. Gonopods diverging from the base. Each gonopod with two short, clavate, uniformly setose prefemoroidal processes (pf1 and pf2); reduced coxal processes: (a) an anterior lobe-like projection and (b) a generally reduced thin, hyaline subfalcate or cone-shaped process not reaching telopodite’s mid-length. Telopodite (T) with a stout stem forming an angular projection at ~ 1/3 to mid-length, distal part twisting and sharply narrowing, tapering towards its apex. Telopodite distally twisted, with one ( A. unidigitis) or more ( A. tridigitis) spine-like or tooth-like processes. Differs from Paracortina and Scotopetalum by the diverging stems of telopodite and from the genus Crassipetalum gen. nov. by the much smaller prefemoroidal process/es and a subfalcate coxal process (b) never surpassing the telopodite.
