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).
