Ovipositor sheaths very slightly protruding beyond apex of gaster. Cercal setae not surpassing apex of gaster.

Male (habitus: Fig. 116 View Figs 112–117 )

Differs from female mainly as follows. Body length: 1.2–1.3 mm. Flagellum brown except basal segments slightly lighter ( Fig. 117 View Figs 112–117 ). Mesosoma and metasoma brown to dark brown ( Fig. 116 View Figs 112–117 ). Coxae lighter basally. Fu1 length 2.4–2.6 × width; length of pedicel plus flagellum 2.40–2.75 × as long as head width. Fore wing length 2.5 × width. MV 3.2–4.1 × as long as SV and 2.1–2.5 × PV. Gaster (inflated) length about 1.3× width, gt1 occupying about half of gaster length.

Distribution

Venezuela.

Remarks

See N. masneri sp. nov. Also similar to N. celebensis sp. nov. and N. ramakrishanai ; from both these species the females of N. merida sp. nov. differ mainly in having a less strongly clavate antenna with both fu7 and the clava dark, contrasting with the other funicular segments ( Fig. 111 View Figs 107–111 ), and a darker mesosoma ( Figs 112–114 View Figs 112–117 ). The males seem most similar to those of N. formiciformis sp. nov. (see the key).
