. Bulletin of the British Museum (Natural History) Entomology. S. J. BROOKS&P. C. BARNARD 197. 199 198 Figs 195-200 Nodochrysa necrota. 195, fore wing; 196, apex of 6 abdomen, lateral; 197, apex of 9 abdomen and praegenitale, lateral; 198, 3 genitalia, caudal; 199, 9 spermatheca, lateral; 200, 9 subgenitale, ventral. Remarks. Species of Nodochrysa have a broad, ovate intramedian cell and very long antennae. Males of the genus are characterized by the lateral lobes on sternite 8+9 and the trunk-like extension of the ectoprocts. Females of Nodochrysa are readily distinguished from other genera by the short, subapical spines on sternite 7. The long antennae, narrow palps and lobes on the ectoproct and sternite 8+9 of males suggest that Nodochrysa may be related to Nesochrysa Navas. Nodochrysa was only briefly described in a key couplet (Banks, 1938a) and since then appears to have been overlooked by subsequent workers. However, the unusual male and female abdomi- nal characters indicate the validity of the genus. The short second cubital cell, broad flagellar segments and relatively distal position of the basal subcostal crossvein place the genus in the Belonopterygini and suggest only a distant relationship with Chrysopa Leach, therefore justifying the elevation of Nodochrysa to full generic status. Biology. Unknown. The gut contents of adults examined during this study did not include insect remains. Genus OYOCHRYSA Brooks Oyochrysa Brooks, 1984: 80. Type species: Oyochrysa ancora Brooks, by original designation. Distribution. West Africa. The genus is known from three species. Diagnosis. Adult. Medium to large lacewings, fore wing (Fig. 201) 14-19 mm; ground colour brown. Head with extensive red or brown mark- ings; palps rounded apically; galea broad; labium.
