A REVISION OF THE ETHIOPIAN DREPANIDAE (LEPIDOPTERA) 31 



Epicampoptera erosa (Holland) 

 (Text-figs. 35, 36 ; Map 2) 



Thymistida erosa Holland, 1893 : 180. [Poor figure.] 



Epicampoptera erosa (Holland) ; Gaede in Seitz, 1927 b : 290. [Poor figure.] 



Epicampoptera erosa (Holland) ; Gaede, 1931 : 52. 



Diagnosis. <^. A comparison of a photograph of the lectotype of erosa with specimens of 

 tumidula has shown that there are probably no significant external differences between the two 

 species. (The subterminal spots on both wings are clearly marked in the lectotype of erosa.) 



<J genitalia (Text-figs. 35, 36) : acuminate valve process less sparsely setose than in tumidula ; 

 anterior basal processes of uncus large, flattened ; apex of aedeagus weakly dilate ; posterior 

 arms of eighth sternite without bulges ; eighth tergite as for tumidula. 



$. Not known. 



Measurements. APR. : not known. Wing : j\ 180 mm. (i). 



Discussion. Probably not separable from pallida, tumidula, or robusta on external 

 characters. The male genitalia of tumidula are similar to those of erosa but differ 

 in the shape of the uncus and aedeagus. 



Distribution (Map 2). Gabon. 



Type. Holland described this species from two males in the Carnegie Museum 

 (wrongly listed by him as a male and a female) from " the valley of the Ogove 

 [Ogowe] River ". I select as LECTOTYPE the smaller of these two syntypes and 

 have labelled the lectotype genitalia slide (No. C-564) as such : I have not seen the 

 whole moth, which has been labelled for me by Dr. H. K. Clench of the Carnegie 

 Museum. The paralectotype is not conspecific with the lectotype and probably 

 belongs to the new species tamsi : I have also seen and labelled the genitalia slide 

 of this specimen. 



Epicampoptera pallida (Tarns) 

 (Text-figs. 37-39 ; Map 2) 



Metadrepana pallida Tains, 1925 : 291. 



Epicampoptera pallida (Tarns) ; Gaede in Seitz, 1927 b : 291. 



Epicampoptera pallida (Tains) ; Gaede, 1931 : 52. 



Description, q. Probably not separable from tumidula and erosa on external characters. 

 (The only specimen available for study is in relatively poor condition.) 



<$ genitalia (Text-figs. 37-39) : acuminate valve process sparsely setose, more slender than in 

 most specimens of tumidula ; anterior basal processes of uncus longer than in tumidula ; 

 aedeagus with two minutely spinose lateral carinae at apex ; each posterior arm of eighth 

 sternite with small, dorsal bulge. 



$. Unknown. 



Measurements. A.P.R. : <J. 20. Wing : g. 17-5 mm. (1). 



Discussion. This species is closely related to pallida, tumidula and erosa, but 

 can be distinguished by the shape of the uncus and process at the base of the valve. 



Distribution (Map 2). Known only from northern Nigeria. 



Material examined. Type. Holotype $, N. Nigeria (Clouston) ; Drepanidae 

 genitalia slide No. 631 ; in the British Museum (Natural History).
