Female (habitus: Fig. 12 View Figs 12–16 )

COLOUR. Head ( Figs 13–15 View Figs 12–16 ) black. Mandibles reddish-brown. Antenna ( Fig. 16 View Figs 12–16 ) with scape whitish to yellowish-brown; pedicel light brown to yellowish-brown; funicle light brown to yellowish-brown basally and increasingly darker towards dark brown to black clava. Mesosoma ( Figs 17–19 View Figs 17–22 ) black. Legs with coxae dark brown; fore and mid trochanters and trochantelli brown, hind trochanter and trochantellus light brown to yellowish-brown; femora brown, apical apices lighter; tibiae yellowishbrown except fore and hind tibiae basally darker; tarsi whitish to yellowish-brown, pretarsi brown. Fore and hind wings slightly and uniformly infumate; venation brown; setation brown. Metasoma with petiole black ( Fig. 19 View Figs 17–22 ); gaster dark brown to black. Body setation, including large, symmetrically arranged setae, dark brown.

BODY LENGTH. 2.75–3.25 mm.

HEAD. Clypeus finely coriaceous ( Fig. 15 View Figs 12–16 ); apical margin very slightly produced. Lower face with shallow piliferous punctures among reticulation. Upper face reticulate, with reticulation becoming denser towards vertex; scrobes moderately deep, smooth; parascrobal area with elongated cells ( Fig. 13 View Figs 12–16 ). Occiput alutaceous; margin sharp ( Fig. 14 View Figs 12–16 ). Toruli with lower margins above lower margins of eyes ( Fig. 13 View Figs 12–16 ). Antenna ( Fig. 16 View Figs 12–16 ) with funicle strongly widening towards clava, with clava conspicuously asymmetric. Upper face and vertex with eight large setae. Head in dorsal view with width 2.0–2.2 × length (85:38) and in frontal view about 1.1× height (85:75). POL about 2.5× OOL (23:9). Eye height about 1.6× length (55:35), about 4.6× malar space (55:12) and about 1.4× as long as scape (55:40). Head width 0.80–0.85 × length of pedicel plus flagellum (85:100). Fu1 length 1.7–2.4× width (12:5); fu7 width 1.7–2.3× length (11.0:6.5); clava length 2.8–3.1× width (40:13).

MESOSOMA. Pronotal collar conspicuously narrower than mesoscutum, with six–eight large setae ( Fig. 18 View Figs 17–22 ). Mesonotum moderately setose dorsally ( Fig. 18 View Figs 17–22 ). Mesoscutum and axillae with dense reticulation ( Fig. 18 View Figs 17–22 ). Scutellar disc similarly sculptured as mesoscutum and longitudinally striatereticulate on frenal area ( Fig. 18 View Figs 17–22 ). Mesepisternum transversely striate-reticulate. Mesepimeron mainly smooth; mesepimeral sulcus well developed ( Fig. 17 View Figs 17–22 ). Propodeum with intricate pattern of carinae forming a V-shaped area anteriorly, the rest with irregular carinae; interspaces smooth to slightly wrinkled ( Fig. 19 View Figs 17–22 ). Macropterous; fore wing ( Fig. 20 View Figs 17–22 ) uniformly and densely setose except for small, elongate bare region. Mesosoma length 1.4× width (100:73) and about 1.8× height (100:55). Pronotal collar about 0.3 × as long as mesoscutum (10:30) and about 0.8× as wide as mesoscutum (61:73). Mesoscutum width 2.3–2.4 × length (73:30). Scutellum length subequal to width (40:42). Propodeum length about 0.5× scutellum length (20:40). Fore wing length 2.4–2.8 × width (195:70); MV 3.4–3.9 × SV (55:14) and 1.9–2.3× PV (55:24).

METASOMA. Petiole ( Fig. 19 View Figs 17–22 ) large, visible part quadrate, with several longitudinal costulae. Gaster ( Fig. 12 View Figs 12–16 ) ovate, length twice width (100:50); gt1 longest, width about 0.9× length (50:58), with hind margin broadly emarginate; gt2–5 short, transverse; gt6 wider than long, triangular; syntergum acutely pointed. Ovipositor sheaths conspicuously protruding beyond apex of gaster. Cercal setae almost reaching gaster apex.

Male (habitus: Fig. 21 View Figs 17–22 )

Differs from female mainly as follows. Body length: 1.5–2.0 mm. Antenna ( Fig. 22 View Figs 17–22 ) with flagellum dark brown. Fu1 length about 2.7× width; combined length of pedicel plus flagellum about 2.5 × head width. Gaster (when not inflated) much shorter than mesosoma, with only gt1 visible.

Distribution

D.R. Congo; Cameroon, Gabon, Ivory Coast, Zimbabwe (new records).

Remarks

See N. africana . Netomocera alboscapus may be only a variant of N. africana with larger eyes than the latter species, but more material is needed to clarify this.
