Etymology
The name of the species (noun in apposition) indicates the name of the Venezuelan state where the

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
), and a darker mesosoma (
Figs 112–114
). The males seem most similar to those of
N. formiciformis
sp. nov.
(see the key).
