7. Cheumatopsyche ampanga species group

Members of this group all have a bilobed segment X with long apicoventral setal lobes ( Fig. 7). The group is close to the C. lepida species group, and the species in the group are separated from those in the C. lepida species group by the different shape of segment X and the reduced setaless mesocaudal lobe. The species in the C. ampanga species group are also similar to species in the C. dubitans species group, but they have very slen- der or even thread-like harpagones. The genitalia of the genus are otherwise unmodified in this group. Segment X is bilobed; the setaless mesocaudal lobe is often reduced or forms convex apical and mesal margins; the setose apicoventral lobes are produced into long processes, either straight or mesad curving in dorsal view, and straight or dorsad curving in lateral view, encircling the wide and deep dorsal and lateral interlobular gaps, and dominating the apex of segment X; the pair of wart-like lateral setose areas are usually located centrally or distally on segment X. The group is diverse on Madagascar, and there are 3 species recorded from the Afrotropical mainland ( C. lobata Marlier from Congo, C. unicalcarata Mey from Kenya, and C. ekona , new species from Cameroon) as well as one species from the Oriental region ( C. spinosa Schmid from China). These four species were originally placed in the C. dubitans species group but are now placed in the C. ampanga species group.
