Etymology

The name of the species (noun in apposition) indicates the name of the Venezuelan state where the holotype was collected.

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).
