Description
Female (habitus: Fig. 12)
COLOUR. Head (Figs 13–15) black. Mandibles reddish-brown. Antenna (Fig. 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) 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); 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); 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). Occiput alutaceous; margin sharp (Fig. 14). Toruli with lower margins above lower margins of eyes (Fig. 13). Antenna (Fig. 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). Mesonotum moderately setose dorsally (Fig. 18). Mesoscutum and axillae with dense reticulation (Fig. 18). Scutellar disc similarly sculptured as mesoscutum and longitudinally striatereticulate on frenal area (Fig. 18). Mesepisternum transversely striate-reticulate. Mesepimeron mainly smooth; mesepimeral sulcus well developed (Fig. 17). Propodeum with intricate pattern of carinae forming a V-shaped area anteriorly, the rest with irregular carinae; interspaces smooth to slightly wrinkled (Fig. 19). Macropterous; fore wing (Fig. 20) 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) large, visible part quadrate, with several longitudinal costulae. Gaster (Fig. 12) 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)
Differs from female mainly as follows. Body length: 1.5–2.0 mm. Antenna (Fig. 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.
