The M. floccosa species-group

Diagnosis. The male genitalia of the species-group are characterised by the relatively short, laterally flattened and medially dilated uncus, and the costa lacking an elongate and slender distal process typical of the M. humilis species-group. Instead of the latter, in most species of the group, the costa is distally dilated and bears a ventrally directed apical process in certain taxa. Only in M. floccosa the costa is gradually distally tapered and dorsally fused with the valvula. The female genitalia of the species-group display no diagnostic differences from the M. humilis and the M. zinchenkoi species-groups.

Note. Most species of the group were illustrated and diagnosed by Volynkin & Huang (2022).
