A REVISION OF THE ETHIOPIAN DREPANIDAE (LEPIDOPTERA) 79 



Gonoreta differenciata (Bryk) comb. n. 

 (Text-figs. 124-127 ; PI. 8, fig. 301 ; Map 4) 



Lomadontophana differenciata Bryk, 1913 : 10.

see below.) 

 Lomadontophana differenciata Bryk ; Gaede, 193 1 : 51. 



Diagnosis. $, $ (see Plate 8, fig. 301). The coloured illustration in Seitz is a good guide 

 to the external appearance of this species but is inaccurate in coloration. The male can be 

 distinguished from the female by the more strongly produced outer-marginal tooth in the 

 fore wing. 



The shape of the eighth abdominal sternum in the male (Text-fig. 125) distinguishes this species 

 from all the other known species of the genus. The female genitalia (Text-fig. 124) separates 

 differenciata from those species whose females are known. 



Measurements. A.P.R. : $. 9 ; ?. 8. Wing : $. 155, 15-0-16-0 mm. (2) ; ?. i6-omm. 

 (i)- 



Discussion. Similar in coloration to forcipulata and contractu but readily dis- 

 tinguished from them by the male and female genitalia. 



Distribution. Cameroun and Ivory Coast. 



Material examined. Type. Holotype $, " Kamerun, Namiong b. Lolodorf B. 

 Lokundjefluss " ; Drepanidae genitalia slide No. 1242 ; in the Zoologisches Museum, 

 Berlin. 



Other material. Institut d'Enseigncment et de Recherches tropicales, Bondy. 

 Ivory Coast : i J, Adiopodoume (Real) ; 1 £, near Nimba, i.viii.1958 (Real). 



This species has previously been known only from the female holotype. The two 

 males listed above, recently collected by Dr. P. Real in the Ivory Coast, exactly 

 match the holotype in coloration and colour-pattern and probably belong to this 

 species, although further material from Cameroun must be studied before the 

 identity of these males can be confirmed. 



Gonoreta contracta (Warren) comb. n. 

 (Text-figs. 128-130 ; PI. 8, fig. 303 ; Map 4) 



Oreta contracta Warren, 1897 : 16. 



Lomadontophana contracta (Warren) ; Gaede, in Seitz, 1927 b : 290. 



Lomadontophana contracta (Warren) ; Gaede, 1931 : 51. 



Gonoreta ansorgei Warren, 1902 : 488. syn. n. 



Gonoreta ansorgei Warren ; Gaede, 193 1 : 41. 



Diagnosis. <$. Plate 8, fig. 303 illustrates a male from Lagos, Nigeria. In some specimens 

 (including the lectotype) the medial shade and posterior subterminal markings on the fore wing 

 are relatively darker. The colour-pattern is very similar to that in differenciata and forcipulata. 

 The eighth abdominal sternum in the genitalia is distinctive (Text-fig. 129). The aedeagus is 

 half the length of genitalia (measured from tip of uncus to saccus), slightly arcuate, unornamented. 



$. Similar to male, but the outer margin of the fore wing is less strongly produced at Cu ia . 

 The shape of the ostial region of the genitalia (Text-fig. 130) distinguishes this species from 

 differenciata and forcipulata. 



Measurements. A.P.R. : £. 9 ; $.8. Wing : <J. 16-0, 16-0 mm. (2) ; $. 16-0, 

 15-5-16-5 mm. (4).
