GENERA OF AFRICAN LYCAENIDAE 63 



Genus ERESINA Aurivillius 



Eresina Aurivillius, 1898, Rhopalocer a A ethiopica : 282 ; 1920 : 341. Type-species : Durbania 



corynetes Smith & Kirby, by original designation. 



Eyes smooth ; palpi long, extending beyond the frons, second segment bearing scales and 

 bristly hairs, third segment rather long, subcylindrical ; antennae of moderate length, barely 

 half the length of costa, the club distinct, oval, flattened ; legs short, scaly, anterior tarsi of £ 

 unsegmented, bearing delicate spines below ; hind tibiae gently curving, thickened and some- 

 what compressed. 



Wing shape. The hind margin of the hind win^s is slightly scalloped. 



Wing venation (Text-fig. 240 corynetes). Very characteristic : on the fore wing vein 6 arises 

 from the upper angle of the cell, 7 arises from 6 and ends at the apex, 8 stalked on 7, 9 absent, 10 

 also branching from 6 about midway between the upper angle of cell and the origin of 7, 11 

 separate from the anterior margin of cell. 



Wing venation in Eresina is not entirely uniform. In some species vein 10 arises nearer to the 

 upper angle of the cell and sometimes actually from this angle, but even in these species the £ 

 genitalia are quite similar to those of the other species. 



Male genitalia (Text-fig. 60). Uncus composed of two subrectangular processes, separated bv 

 a deep division, each bearing a sort of triangular crest at an oblique angle ; no subunci ; tegu- 

 men rather big ; vinculum broad dorsally ; inferior fultura with a short peduncle fused to the 

 extreme base of the valves and tightly enclosing base of the penis ; valves oblong, falcate at the 

 apex (slightly asymmetric in the bolotype ol corynetes) ; penis doubly curved (S-shaped) with 

 a very slender tip and distally widely open dorsally, vesica bearing two short opines and other 

 smaller ones. Apex of uncus covered with rather long line hair, extremity of the values lightly 

 pilose and their ventral margins shortly but densely pilose. 



In most species of Eresina the male armature is as in corynetes, i.e. with a deeply 

 divided uncus and an S-shaped penis. In toroensis (Text-fig. 61) and conradti the 

 uncus is only shallowly divided ; in crola, fnsca and pscudofitsca the penis is simply 

 curved and in conradti its extremity is bind.
