Cheumatopsyche lepida species group

Species of this group frequently have forewing patterns that can be used for separating many of the species. The genitalia morphology of the species in the group follows the ancestral Cheumatopsyche plan. An exception is the characteristically trilobed segment X with long and upcurving ventroapical lobe. Segment IX bears only seldom the apomorphic ventrocaudal spiny lobe. Segment X is trilobed. The unsetose mesocaudal lobe is well developed, triangular, rounded or quadrangular. If this unsetose mesocaudal lobe shortened just into a convex margin a transient state occurs making the species easily misidentified as belonging to the C. dubitans species group having bilobed segment X. A pair of setose ventroapical lobes produced into a long process being straight, mesally or laterally curving in dorsal aspect; and curving dorsally in lateral aspect, encircling the wide and deep dorsal and lateral interlobular gaps in dorsal and lateral aspects while dominating the termination of segment X. A wart-like, lateral, setose area, the vestigium of preanal appendages, is usually located distad from the centre of segment X. The species group range covers the Oriental, West Palearctic, East Palearctic and Afrotropical biogeographic regions ( Oláh et al. 2008).
