light greyish ochreous. Thorax short and robust, dorsum densely 

 covered by minute granulations which get scarcer laterally, with dense 

 and rather long greyish pubescence. Dorsum dark greyish brown 

 with a distinct greenish shade ; sides and ventral side gradually 

 lighter. Metastigma black. Legs uniform light ferruginous. 



Abdominal segments 1-2 moderately enlarged in lateral, very little in 

 dorsoventral dimension ; 3 moderately contracted, end of 3-10 almost 

 cylindrical, slender. Earlets of second segment moderate, cut straight 

 with 6 rather robust denticles. Abdomen dull ferruginous, joints 

 and carinae narrowly blackish; no distinct markings (destroyed?). 

 Appendages, Text-fig. 61. 



Wings irregularly tinged with greyish yellow (as nearly always 

 in fully mature specimens of Gyuacantha) ; sub-costal and cubito-anal 

 space yellowish at base, this colour not deep and rather indistinct. 

 Pterostigma dull ochreous. Venation much denser than in following 

 species (fig. 13 in the Schultze paper). 



$ . Very similar to male in colour, somewhat lighter (not so 

 mature). Abdomen more robust, less contracted at third segment. 

 Ovipositor very long and robust, and consequently the ninth segment 

 elongate (6 mm.) and also dilated in dorsoventral dimension 

 (Text-fig. 6-2).

A very distinct species, resembling by its comparatively short and 

 broad wings and small size a type represented by the Asiatic species 

 G. bayadera, Sclys. It is the smallest of known African Gynaeanthae. 



c. Labium and labrum ochreous. Face and frons anteriorly 

 olivaceous. Dorsal surface of frons ochreous in basal half, turning 

 gradually to olivaceous anteriorly. T-spot deep brown, longitudinal 

 part broad, lined by a very narrow light yellowish line ; transverse 

 part reduced to a rather small, almost rhomboid dilatation. Thorax 

 greyish olivaceous ; dorsum finely granulate, with rather long, fine, 

 whitish hair ; a few blackish-brown markings ; a round point near the 

 dorsal end of humeral and second lateral suture, traces at the ventral 

 sutures and a transversely triangular spot on metasternum. Legs 

 short. Femora ferruginous, very slightly and gradually darker at 

 distal end ; tibiae black internally, light ochreous externally ; tarsi 

 black.
