THYRIDIDAE OF AFRICA AND ITS ISLANDS 53 



of the latter genus have a secondary sac on the bursa which is absent in Neobanisia 

 and there are other differences in the male. It is possible that Neobanisia may be 

 regarded as a subgenus of Canaea but a decision on this will have to await a revision 

 of the Oriental and Australian species of Canaea. 



Generic description. Eyes without interfacetal hairs. Labial palps 3-segmented. 

 Antennae minutely ciliate. Frenulum in female double or triple. Fore wing with radial veins 

 from cell or some fusion of radials. Proboscis well developed. Fore tibia with epiphysis. 

 Hind tibia with 2 pairs of spurs. Tarsi each with apical pair of spines. Male with simple or 

 clavate uncus. Socii well developed. Usually some modification of base of sacculus, often 

 spiny. Cornutus in aedeagus. Female with highly modified and sclerotized ostium. 



Biology: No information. 



Key to the African species of NEOBANISIA 



1 Fore and hind wing colour black, often a small white spot on fore wing fuliginea (p. 53) 



- Brown or reddish brown species ......... 2 



2 (1) Larger species, wing over 11 mm. Orange-brown, often either with a dark mark 



or translucent area in fore wing ........ 4 



- Under 11 mm wing. Reddish or brown species ...... 3 



3 (2) Reddish brown species, not heavily patterned, sometimes with small translucent 



area in fore wing ........ inoptata (p. 56) 



- Brown species, patterned, with yellowish brown or white areas, often suffused 



with red .......... zamia (p. 57) 



4 (2) Wing 11-14-5 mm. Generally reddish brown, male genitalia as in PI. 28, fig. 148. 



Female genitalia as in PI. 50, fig. 288 .... joccatia (p. 54) 



Wing, 13-18 mm. Males grey-brown. Females reddish brown. Male 



genitalia PI. 28, fig. 149. Female genitalia PI. 51, fig. 295 . clathrula (p. 55) 



Neobanisia fuliginea sp. n. 



(PI. 5, fig. 16; PI. 24, figs 127-129; PI. 28, figs 151, 152; PI. 50, figs 290, 291; 



Text-fig. 1) 



<J. Wing, 10-10-5 mm. Vertex black, irrorate with white. Strongly sclerotized projection 

 on frons in front of antennae, with sharply truncate, white end. Flat sclerotized "roof" above 

 base of proboscis (PI. 24, figs 127-129; Text-fig. 1). Antennae ciliate. Labial palps short, 

 approximately equal to diameter of eye, third segment 1/3 length of second. Thorax black 

 with white-tipped scales. Legs black, white scales in ring at end of tibia and each tarsal 

 segment. Hind tibia with scale-tuft, outer spur of distal pair slightly more than 1/2 length 

 of inner spur. Proximal inner spurs longer than distal ones. Fore wing, pattern as in PI. 5, 

 fig. 16, sooty black with dark ante- and post-median fascia, some black wing scales tipped with 

 white. White spot behind cell. Underside paler, more white-tipped scales. Costal margins 

 with darker patches, white spot clearer. i? x approaches R 2 but does not join. R 3 and i? 4 

 separated at origins by 2 X distance of i? 4 from R & . \A and 2 A join very near base to make 

 single vein to wing margin. Hind wing, colour and pattern as fore wing, but without white 

 median spot. Sc+R x and Rs almost touch for part of length. 



Genitalia $ (PI. 28, figs 151, 152). Uncus simple, slightly swollen at apex. Socii with 

 long scales. Gnathus simple, no median projection. Basal part of sacculus covered with 

 long spines. Juxta plate-like. Aedeagus with apical swelling, lightly sclerotized plate-like 

 cornutus with teeth, strongly curved with prominent sclerotized projection near base, similar 

 to species of Chrysotypus.
