A REVISION OF THE ETHIOPIAN DREPANIDAE (LEPIDOPTERA) 29 



Epicampoptera tumidula sp. n. 



(Text-figs. 31-34 ; PI. 4, fig. 286 ; Map 2) 



Description <$. Palp and front of head greyish brown ; vertex pale buff ; shaft of antenna 

 pale buff proximally, becoming more greyish towards apex ; posterior margin of head greyish 

 brown laterally and ventrally. 



Thorax very pale buff. Legs very pale buff, with front surface of prothoracic femur, tibia and 

 tarsus greyish brown. 



Upper surface of both wings (Plate 4, fig. 286) very pale buff or very pale greyish buff (holo- 

 type) lightly speckled with dark brown ; fore wing with weakly marked discocellular spot, trace 

 of postmedial fascia in some specimens (not holotype), well marked reddish brown subterminal 

 spot between M 3 and Cw la , and usually with trace of second subterminal marking between A/ 2 

 and M 3 ; hind wing with well marked discocellular spot, usually with weakly marked postmedial 

 fascia (including holotype), and with two reddish brown subterminal markings between M 2 and 

 Cw la (weakly marked in holotype ; sometimes strongly marked). Under surface of fore wing 

 paler than upper surface, speckled and striate with greyish brown except at anal margin ; 

 discocellular spot and postmedial fascia dark grey ; fringe yellowish brown proximally, brownish 

 white distally. Under surface of hind wing paler than fore wing, striate with greyish brown along 

 costa and outer margin ; discocellar spot dark grey ; trace of postmedial fascia present in few 

 specimens (including holotype) ; fringe as for fore wing. 



Abdomen similar in colour to corresponding surface of hind wing. 



o* genitalia (Text-figs. 31-33) : acuminate valve process sparsely setose ; anterior basal 

 processes of uncus short ; apex of aedeagus with lateral lobes or carinae ; posterior arms of 

 eighth sternite without bulges. 



$. As for male but wings less strongly produced at outer margin between ,l/ 3 and Cn la . 



$ genitalia (Text-fig. 34) : ostial segment particularly heavily sclerotized at ostium. 



Measurements. A.P.R. : 6* . ?• J 9 Wing : <$. 190, 17 -0-21-0 mm. (35) ; $. 22-0, 

 20-5-23-0 mm. (4). 



Discussion. Apparently indistinguishable externally from pallida, erosa or 

 robusta. The male genitalia are most like those of erosa, but the shape of the uncus 

 and the aedeagus is diagnostic. 



There is some individual variation in the markings of both surfaces of the wings 

 (see Description). 



Distribution (Map 2). Occurs in Gabon, where it is possibly sympatric with 

 erosa, and in Cameroun. A single male from the Congo (in the Musee Royal de 

 l'Afrique centrale, Tervuren) probably also represents tumidula, although further 

 material is needed before this can be confirmed. 



Material examined. Type. Holotype <$, Cameroun, Ja River, 2,000 ft., dry
