Iris 1:51; Aurivillius, 1898 : 300 ; 1923 : 361. Type- species : Megalopalpus simplex Rober, by original designation. M. simplex was described as coming from Borneo, very probably the result of an error in labelling, for, as far as I know, it has never been found again in the Oriental Region, whilst it is common in Africa from the Gold Coast, Liberia, Nigeria, Cameroon, Gaboon and Congo to Uganda. Head small ; eyes smooth ; palpi very long, even longer than in the Indo-Malayan genera Miletus and Allotinus, ascending, laterally compressed, clothed with short, adpressed hairs, third segment slightly longer than the second ; antennae slender, less than half as long as the costa, club fusiform, very slightly swollen ; thorax slender ; abdomen long, protruding far beyond the anal angle ; $ fore leg with tibia slightly shorter than the femur, tarsus very long, unsegmented, pubescent and with a single claw ; mid and hind legs with tibiae slightly shorter than femora, first tarsal segment very long ; no terminal claws In the shape of the hind wings the sexes show a marked difference. The outer margin in the $ has a slight angle at the end of vein 5, which in the $ is much more prominent. Wing venation (Text-fig. 273) : fore wing with 11 veins, vein 9 being absent ; hind wing with a short precostal vein which arises from vein 8 near its base. Male genitalia (Text-fig. 90) : uncus composed of two enormous triangular lobes with sharp pointed apices, fused at their base to the tegumen and separated by a very deep groove ; subunci fairly robust, regularly curved and tapering to the apex ; tegumen well developed with
