Nidicola Harris & Drake, 1941

( Figs. 5 , 22 )

Nidicola Harris & Drake, 1941: 343 . Type species: Nidicola marginata Harris & Drake, 1941 .

Diagnostic characters. Small size (1.6–2.1 mm), oblong to obovate. Upper surface depressed. Head wider than long; eyes small; rostrum long, surpassing mid coxae. Pronotum much wider than long; anterior margin nearly straight; lateral margins widely explanate, carinated and straight, with anterior angles rounded; basal margin concave. Polymorphic wings, from well developed to not reaching the tip of abdomen, dense and finely punctured, especially in clavus; exocorium narrow. Legs moderately long, with short and slender hairs; femora not enlarged; fore coxae with four or five long setae; male fore tibiae with row of teeth on inner surface; fossula spongiosa small. Female with ovipositor reduced. Left paramere slender, long and slightly spiraled. Ostiolar peritreme ( Fig. 22 ) gently curved forward, basal half a little wider than apical one (a little different to peritreme drawed in DRAKE & HERRING (1964) that is parallel-sided), and apically rounded with small excentric acute tip; median sulcus arises from top of peritreme; dorsal margin of metapleura smooth.

Studied material. Nidicola mitra Drake & Herring, 1964 : NICARAGUA: León, V. Telica, 4-IX-1991, 2 JJ 1 ♀, Nolo – González lgt., en nido de Nasutitermes sp. ( MACN).

Remarks. This genus includes a very peculiar group of species restricted to southwestern USA, Mexico and Central America. The long setae on fore coxae are probably related to a stridulatory function.
