Striglina vindicta sp. n. 



This dark-coloured species is separated into three subspecies, although little 

 material was available for examination. This species can be separated from S. 

 clathrata by the shape of the uncus and gnathus. The subspecies are separated on 

 the basis of size and colour and some differences in the genitalia. Externally the 

 Cameroon specimens of S. vindicta vindicta can be separated from the Congolese 

 subspecies, S. v. congolensis by the size and intensity of colour and in the genitalia 

 by the shape of the juxta. The Ivory Coast subspecies, S. v. ivoriensis, is separated 

 from the other two subspecies by its more yellow-brown colour (approaching 5. 

 ramosa in colour), and by differences in the shape of the juxta and gnathus Without 

 material from the regions between these subspecies, their exact status is in some 

 doubt but the specific difference from 5 ramosa and S. clathrata is quite clear. 



cJ. Antennae ciliate. Labial palps upturned, reaching above vertex, third segment small, 

 less than 1/5 length of second segment. Frons rounded between eyes. Eyes without inter- 

 facetal hairs. Hind tibia with scale crest, proximal pair of spurs long, almost reaching to apex 

 of shortest distal spur. Distal spur with outer one 2/3 length of inner spur. Hind tarsi each 

 with rows of spines. Fore wing, pattern and colour see under individual subspecies. Veins 

 R 2 and R 3 very close together, separated more widely from i? 4 . lA approaches hind margin 

 from the base but then curves inward toward termen. Hind wing, pattern and colour, see 

 under subspecies. Sc+R 1 and Rs approach closely, but do not join. 



Genitalia^ (PL 32, fig. 173). Uncus short with enlarged lateral lobes. Gnathus arms with 

 sclerotized process on each side of mid-line. Subscaphium sclerotized with prominent hairy 

 pads. Valves reduced to narrow strips. Lateral lobes of juxta elongate and spiny. Sacculus 

 broad, saccus very reduced. Aedeagus with prominent apical process. 



$. Unknown.

Striglina vindicta vindicta ssp. n. 



(PI. 7, fig. 25; PI. 32, fig. 173) 



<£. Wing, 10 mm. Vertex brown. Thorax brown. Fore wing, pattern as in PL 7, fig. 25, 

 dark reddish brown with broad, dark fascia from apex of fore wing to middle of hind margin 

 of fore wing. Underside more reddish brown, less heavily marked than upperside. Hind wing, 

 darker than fore wing with slightly paler basal area. 



Genitalia <3 (PL 32, fig. 173). Lateral lobes of juxta spiny, pointed. Median juxta plate 

 roughly pear-shaped, with small spines. Apex of aedeagus with stout thorn-like process. 



$. Unknown. 



Discussion. This subspecies can be separated from v. congoensis by its more 

 distinct pattern and by the shape of the gnathus and juxta. The wing shape is 

 similar to S. clathrata but differs in not having R 4 + R 5 joined in the fore wing and 

 other differences can be seen in the genitalia.
