66 P. E. S. WHALLEY 



The tarsi in both Groups i and 2 usually have rows of spines on each segment 

 but in some species in each group there are those where the spines are reduced to 

 the apical pair. The valves are usually reduced and may be represented by only a 

 narrow strap-like piece. In the strigifera-group the valve is highly modified and 

 toothed In S. tincta the valve is relatively simple but there is a large scale tuft 

 on it and in S. nigranalis there is a strong lateral process on the valves. Only one 

 species (S. tincta) has a relatively simple uncus, all the other species have various 

 modifications. All the females of the genus have a similar shaped bursa with a 

 signum usually present (except nigranalis and rothi) and usually have a strongly 

 sclerotized ostium. 



Certain aspects of the morphology of the genus indicate that it may be related to 

 Banisia Walker but a close analysis will have to await generic revisions (in progress). 



Species of Striglina are widespread in West and Central Africa but few have been 

 found in East Africa and none in South Africa, although they occur in Rhodesia. 

 One species of the genus occurs in Madagascar (Whalley, 1967). Most of the African 

 species come from regions of higher rainfall and the little data available suggests 

 that they are forest-living species. 



The genus is widespread in the Indo-Pacific Region with many species but has a 

 few species in the New World. 



Generic description. Eyes with or without interfacetal hairs. Proboscis present. Labial 

 palps 3-segmented. Fore tibia with epiphysis. Hind tibia with two pairs of spurs. Tarsi 

 with spines, either an apical pair or rows of spines on each segment. Hind wing with Sc+R 1 

 and Rs free or joined for part of length. Uncus usually modified. Valves reduced or modified. 

 Signum usually present. Ostium often highly sclerotized. 



Biology. 5. clathrata has been bred from Coffee bushes in Kenya (no indication 

 if arabica or robusta but probably the latter), where it was rolling the leaves. S. 

 rothi has been bred from the leaves (?) of Terminalia ivoriensis. No data are available 

 for any other African species. In India S. lineola Guenee has been bred from a variety 

 of plants (Albizza, Bauhinia, Cassia, Milletia, Xylia, see Beeson, 1941).
