Smeryngolaphria bromleyi sp. n.

Figs 4 , 7 , 10-11 , 22-27 , 28 Etymology: Named after Dr Stanley Bromley who was first to record the presence of this genus in Africa.

Description: Based on holotype ♂. Similar to S. pallida except for following details.

Head: Antenna ( Figs 10-11 ) brown-yellow but distal part of flagellomere darker brown; scape and pedicel with yellow setae only; flagellomere with oval-shaped

anterior depressed area. Face fairly narrow, face width: maximum head width ratio 7,2: 1 ( Fig. 7 ). Silvery scale-like mystacal setae narrower than in pallida but otherwise with similar appearance and distribution. Setae and bristles of vertex shiny yellow. Ocellarium with 1 black and 1 yellow bristle. Upper occipital bristles shiny yellow. Proboscis and palpi brown-yellow.

Thorax: 1 strong yellow notopleural bristle accompanied by 2 black setae; 2 black supra-alars (1 yellow on left side); 1-2 black postalars; ca 8 black scutellar bristles; all scutellar setae black. Wing length 5,7 mm; venation as in ♀; distribution of microtrichia not as extensive as in pallida-cells c, r l, r 2+3, r 5 and discal also with small bare areas.

Abdomen: All terga similar in colour and with short black setae dorsocentrally. Genitalia as in Figs 22-24 , quite different from pallida ; aedeagus with moderately long terminal filaments.

Female: 1 ♀

paratype pinned together with holotype ♂ (captured whilst copulating). Similar to ♂. Antennal ftagellomere somewhat more attenuate. Distribution of scale-like mystacal setae as in

♀

pallida

but normal setae all white. Ocellar bristles gold-yellow. All marginal bristles of mesonotum and scutellum yellowbrown except for 2 black ones on scutellar margin. Wing 6,8 mm long, venation as in Fig. 4 . Genitalia as in Figs 25-26 ; cerci distally rounded. Egg ( Fig. 27 ) (dissected from body cavity) similar to pallida but tiny spines somewhat smaller.

Material examined: NIGERIA: 1 ♂ holotype 1 ♀ paratype, Nigeria, Sapoba [6° 06'N: 5°53 'E], 17.iv.1946, M. A. Cornes, Forest, 6622 ( NMWC). Distribution as in Fig. 28 .
