Notes

Among the species with all tibiae much thickened in that sex, males can be distinguished by having the palpus entirely pale yellow and fore tarsus entirely dark brown to black. The form of the surstylus and cercus ( Figs 43, 44 View Figures 43, 44 ) is very different from that of related species. Females differ from those of all other species of the genus in their entirely dark fore tibia and tarsus, and from those of some related species in the entirely pale palpus (clean, non-greasy specimens).
