); pygofer appendage slightly curved, not exceeding caudal margin of lobe in lateral view. Subgenital plate in lateral view curved gradually caudodorsad apically, expanded apically; group A with 4 moderately long setae; group B with 21 short microsetae, group C arranged in two rows of macrosetae, from medial margin to apical margin of inner side, group D irregular, with most setae short except near apex (
