A REVISION OF THE ETHIOPIAN DREPANIDAE (LEPIDOPTERA) 71 



species in his genus, subtilis and differ enciata, and selected the former as the type- 

 species. Comparison of the holotypes and topotypical material of the type-species 

 of Gonoreta and Lomadontophana has shown that they are congeneric and that 

 Lomadontophana is a junior synonym of Gonoreta. Warren (1923 : 447) added 

 subrosea to Gonoreta. Gaede, in Seitz, (1927 b : 290) listed under Lomadontophana 

 the two originally included species and added Oreta contracta Warren and Oreta 

 gonioptera Hampson, and under Gonoreta listed only ansorgei Warren. In his 

 catalogue Gaede (1931 : 41 and 51) followed his previous revision in Seitz (1927 b : 

 290) but included subrosea Warren under Gonoreta. 



There has been some confusion concerning the location in the literature of the 

 original description of G. subrosea Warren. Gaede (1931 : 41) cites as the reference 

 " Novit. zool 9 : 488 (1902) " which is the same wrong reference as that given by 

 Warren (1923 : 490). It is in fact in this latter work (Warren 1923 : 477) that I 

 believe the first reference and description occur, even though Warren heads the 

 description " subrosea Warr." instead of subrosea sp. n. The reason for this con- 

 fusion appears to be that Warren believed that he had already described subrosea in 

 1902 (Novit. zool. 9 : 488), whereas he had in fact described here as new the super- 

 ficially similar G. ansorgei. There seems to be little doubt that the original descrip- 

 tion of subrosea is Warren's description in Seitz (1927 b : 477). Examination of the 

 type of subrosea has shown that this species must be removed from Gonoreta. It is 

 close to Oreta fulgens Warren, another Borneo species, and can be placed in the 

 same genus until a revision of Oreta Walker is undertaken : Oreta subrosea (Warren) 

 comb. nov. 



In the following pages one species name is relegated to synonymy and six new 

 species are added to the genus Gonoreta. A new subspecies is also described. Ten 

 species are now included in this genus. 



Discussion. This genus is probably most closely related to the endemic 

 Madagascan genus Gonoretodes, from which it can be separated by the lamellate (not 

 pectinate) antennae, the genitalia, and by the fact that Sc + R t approximates to Rs 

 for a short distance distal to end of the cell and does not anastomose with Rs as in 

 Gonoretodes. The shape of the wings distinguishes Gonoreta and Gonoretodes from 

 the remaining Ethiopian genera of Drepanidae. 



The colour-pattern of the wings, antennal pectination ratio and the lack of a 

 signum in the female genitalia separate opacifinis and bispina from the rest of the 

 genus, though it can not be divided into species-groups until females of albiapex, 

 cymba, angidosa and gonioptera have been examined. 



In those species where a large enough series was available, considerable, individual 

 variation in the coloration of the wings was evident. 



Only subtilis is known to be polytypic. 



Distribution. Three species of Gonoreta have extensive ranges. For example, 

 subtilis is known from the Ivory Coast and Sierra Leone as subspecies reali, and 

 as the nominate subspecies from much of the Congo Basin, the rain-forests of the 

 Usumbara Mountains in eastern Tanganyika and the Malaba Forest of Kenya. 

 The most extensive distribution is that of opacifinis which not only extends across
