THYRIDIDAE OF AFRICA AND ITS ISLANDS 71 



<£. Wing, 9-10-5 mm. Vertex and frons brown. Antennae minutely ciliate. Labial palps 

 slightly longer than diameter of eye, third segment of palp 1/4 length of second segment. Eyes 

 without interfacetal hairs. Thorax brown. Hind tibia with proximal pair of spurs long, distal 

 pair short. Tarsi with rows of spines along each segment. Fore wing, pattern as in PI. 1, M, 

 grey-brown with white maculations. Veins R t and i? 5 with common stalk. Underside, paler. 

 Hind wing, as fore wing, Sc+R 1 and Rs approach closely but do not join. 



Genitalia $ (PI. 30, figs 162, 165). Uncus bifid. Gnathus a row of pegs adjoining spiny 

 and lightly sclerotized subscaphium. Valve very reduced. Sacculus enlarged. Base of valve 

 with prominent peg-like process. Juxta, two lateral lobes, broader near middle. Aedeagus 

 with at least 10 long cornuti. VHIth abdominal sternite deeply incised. 



2- Wing, 11-12-5 mm. Colour and pattern as male. Labial palps long, 2-2^ X diameter 

 of eye, third segment of palp 1/2 length of second. 



Genitalia ? (PI. 53, figs 306-308). Anal papillae short, strongly sclerotized ostium. First 

 part of duct sclerotized, rest lightly sclerotized and coiled. Signum a narrow, minutely toothed, 

 band across bursa. 



Discussion. West African and Western Ugandan specimens are smaller and 

 darker than those from the Cameroon, otherwise there is little variation in the 

 extent of the dark area on the wings. This subspecies can be separated from S. 

 clathrata amani by its smaller size (9-13 mm, c. clathrata; 12-14 mm, c. amani) and 

 by the ground colour, which is grey-brown in c. clathrata but reddish brown in c. 

 amani. From c. declivita it can be distinguished by its smaller size and by differences 

 in the shape of the process at the base of the valve, the juxta and by the uncus.

Striglina clathrata amani ssp. n. 



(PL 1, N; PL 30, fig. 163) 



cj. Wing, 12-14-5 mm. Morphologically similar to nominate subspecies but larger and with 

 more reddish brown wing colour. Separated from c. declivita by the reddish colour of the wing 

 (PI. 1, N) and shape of parts of the male genitalia.
