Male genitalia: Tegumen weak, higher than broad, top obtuse.
Uncus absent. Tuba analis moderate, developed, supported by a
transverse band (subscaphium). Valva characteristic, triangular,
outer angle produced, with a long pencil of bristles (Spc2), with a
strong triangular blade at its foot, a large patch of bristles in disc
(Spci) ; cucullus thinly bristled, sacculus narrow, complete. Aedeagus
