Genus MICROPENTILA Aurivillius 



Micropentila Aurivillius, 1895, Ent. Tidsk. 16 : 202 ; 1898 : 281 ; 1920 : 339. Type-species : 

 Liptena adelgitha Hewitson, 1874, by original designation. 



Eyes glabrous ; palpi of medium length, shorter than in Liptena, the second segment clothed 

 below with stiff hair or hair-scles ; third segment subconical ; antennae of medium length 

 reaching beyond the tip of the discal cell, the club oval, short, sharplv defined ; legs black, 

 ringed with white, the <J fore tarsi short, unsegmented, finely spinose beneath. 



Wing shape. Fore wing costa rather strongly curved, the outer margin convex ; hind wing 

 oval with a rather well marked anal angle. 



Venation (Text-fig. 247). Fore wing with 12 veins ; the stem of 7 + 8 + 9 arises from the 

 upper angle of the cell or very shortly before it ; hind wing, 3 and 4 free from lower angle of 

 cell, or very shortly stalked, 7 a little before the upper angle of cell. 



Male genitalia (Text-fig. 55). Uncus divided into two subtriangular processes with rounded 

 extremities separated by a deep indentation ; subunci long slender and curved ; tegumen 

 large ; vinculum with a slender saccus ; valves oblong and tapering evenly to a blunt apex ; 

 penis basally bulbous and sheathed by a small inferior fultura, then cylindrical, dilated and 

 notched at the tip ; uncus clothed in long hair, only the ends of the valves slightly pilose. 



In collaboration with N. H. Bennett of the British Museum (N.H.) I have recently 

 published a revision of the genus Micropentila (1965 : 397-434, 31 figs, 4 plates), in 

 which the genitalia of almost all the known species are figured, and to which reference 

 should be made. Not all the species have genitalia like those of M. adelgitha. As a 

 rule the uncus is not so deeply divided, the saccus is sometimes broadly spatulate, 

 and the penis in particular shows many variations. According to the characters of 

 the penis we have divided the genus into nine sections : — 

 Section A Penis bulbous at base, excised apically : — 



adelgitha, subplagata, souanke 

 Section B Penis long and bent ; valves as in some Liptena : — 



fulvnla 

 Section C Penis long, cylindrical, bent at right angles near the base, its apex 

 rolled back : — 



adelgunda (Text-fig. 56), bitjeana, dorothea, gabunica 

 Section D Penis rather long, ending in a fine point : — 



brunnea (Text-fig. 57), victoriae, katerae, flavopunctata, jacksoni, 

 bakotae, nigeriana, mpigi, fontainei, fuscula, ogojae, kelleana.
