Genus PARAPHNAEUS Thierry-Mieg 



Paraphnaeus Thierry-Mieg, 1904, Naturaliste : 140. Type-species : Aphnaeus hutchinsoni 



Trimen, by monotypy. 

 Aphnaeus Hubner (partim) ; Aurivillius, 1898 : 328 ; 1924 : 409 ; Murray, 1935 : 82 ; 



Swanepoel, 1953 : 163. 



Eyes, palpi and antennae similar to those of Aphnaeus ; thorax robust, clothed below with 

 long silky hairs ; o* fore leg, femur clothed with long fulvous hairs, tibia shorter than the femur, 

 tarsus short, unsegmented, bearing many spines below ; mid and hind legs with tibiae shorter 

 than femora, metatarsi long. 



Wing shape. Similar to that of Aphnaeus except that the outer margin of the fore wing is a 

 little more convex between the apex and the ending of vein 4. 



Wing venation (Text-fig. 300). Same as that of Aphnaeus. 



Male genitalia (Text-fig. 138). Uncus, subunci and tegumen as in Aphnaeus, except that the 

 posterior edge of the dorsum has a rounded median prominence ; vinculum fairly wide ; lower 

 fultura consists of a small shield-shaped plate with a deep notch in the upper edge ; valves 

 like those of Aphnaeus, the upper and lower processes of each valve separated in their distal 

 halves, the middle portions of the upper processes folded over the inner face and connected by a 

 membranous strip which passes above the penis ; penis very bulky, internal portion swollen, 

 the external portion bearing on the dorsal surface, at the base, a sort of lobe bearing short 

 regular teeth on its inferior edge, the apex of penis split into two longitudinally ; vesica with 

 cornuti ; uncus and distal half of valves clothed with fine hairs. 



The early stages of P. hutchinsoni drucei Neave have been described by Jackson 

 (1937, Trans. R. ent. Soc. Lond. 86 : 216). The caterpillar lives on Acacia stenocarpa 

 Hochst., Entada abyssinica Stend., and on certain species of Loranthus in symbiosis 

 with ants. 



The genus Paraphnaeus, which has only one species, is very closely allied to the 

 genus Aphnaeus, except that the lower fultura reminds one of that of Apharitis and 

 Spindasis, and that the shape of the penis differs slightly from that of Aphnaeus.
