Striglina trepida sp. n. 



(PI. 8, fig. 34; PI. 31, figs 168, 169; Text-fig. 12) 



<J. Wing, I3-I4'5 mm. Externally as S. strigifera. Discal spot slightly less prominent on 

 underside. 



Genitalia $ (PI. 31, figs 168, 169). Uncus bifid with two lateral finger-like processes. Apical 

 process of valve slightly spined. Gnathus as S. strigifera. Costal process on margin of valve 

 with one or more arms, one curved, slender, the other toothed at tip. Small tooth on ventral 

 edge of valve near base of apical process. Juxta with two lateral processes, each with strongly 

 toothed inner surface. Vlllth abdominal sternite with sclerotized plate as in Text-fig. 12. 

 Aedeagus with two groups of cornuti. 



$. Unknown. 



Discussion: This species cannot be separated on external characters from 5. 

 strigifera but they differ in the genitalia. S. trepida is separated from S. strigifera by 

 the bifid basal costal process of the valve, the strongly toothed juxta lobes and the 

 toothed ventral valve margin. Slight variation from the holotype in the shape of 

 the sternite was present in the Congo specimen.

<J. Wing, 11 mm. General morphology as in S. strigifera. Pattern as in PI. 8, fig. 33.

 small. Gnathus similar to strigifera. Terminal process of valve toothed. Basal process on
