Apoprogones hesperistis

A. hesperistis has strongly clubbed or hooked antennae, like a butterfly, giving it a skipper-like appearance (Shields and Dvorak, 1979), hence the species name. The hindwing is not tailed, unlike Sematurinae which have the veins "M2" and "M3" in the hindwing bearing tails (Minet and Scoble, 1999). The adult male moth has a pair of hair-pencils at the base of the abdomen. On the head (in contrast to Sematurinae) the ocelli are absent and the compound eyes are not hairy; the wing venation differs between subfamilies and the forewing "M1" vein is "free" as opposed to sharing a "stalk" with vein "R1" in Sematurinae (Minet and Scoble, 1999). These and other structural differences have been enough for some authors to consider the African and American groups distinct at family level.
