This genus was first described by Edward Meyrick in 1885 as a replacement name for the genus Thyone.[4][3] Meyrick gave more detail in 1886 as well as in 1892.[5][6] This genus was reinterpreted by John S. Dugdale in 1971.[7][3] Dugdale stated that the species within this genus
are distinguished from other genera by their possession of a rudimentary calcar (often a pair of contiguous hairy knobs), of a smooth, unscobinate saccular appendage, a deflexed, strongly sclerotised, sharp aedeagus apex in the ♂, and in the ♀ by the ductus bursae being not longer than wide, and containing the internally prolonged and fused ostiolar lamellae. The corpus bursae is reflexed dorsad of the ductus bursae. As in Helastia species, the ductus seminalis arises on the corpus bursae by the corpus/ductus bursae junction.[7]
Face with tuft or hardly projecting scales. Palpi moderate, porrected, rough-scaled. Antennae in ♂ bipectinated, apex simple. Thorax glabrous beneath. Posterior tibiae with all spurs present. Fore wings with areole simple. Hind wings with 8 anastomosing with cell from near base to beyond middle.[6]
Distribution
