DICOPUS Enock, 1909

( Figs 114–118 )

Dicopus Enock, 1909: 455 . Type species: Dicopus minutissimus Enock, 1909 , by monotypy. See Huber et al. (2020) for generic synonyms and their type species.

Diagnosis. Face with toruli about their own height from transverse trabecula ( Fig. 114a ); vertex separated from occiput by a medially divided vertexal trabecula ( Fig. 114b ); mandibles when closed pointing ventrally, not overlapping medially ( Fig. 114a ), each with one short and one long tooth; funicle 7-segmented with fu 2 about equal to fu 1 or fu 3 ( Fig. 115 ); fore wing extremely narrow, the posterior margin concave, with narrowest point about one venation length distal to venation, then distinctly widening to apex ( Fig. 116 ); hind wing narrow for about 4 venation lengths beyond hamuli then becoming uniformly wider to apex ( Fig. 116 ); metasoma with genitalia short, in about apical third.

Remarks. Dicopus belongs to the Alaptus group of genera. It is most similar to Dicopomorpha in having the funicle clearly 7-segmented, but the fore wing of Dicopus is narrower and the head shape and mandibles have one short and one long tooth and do not cross medially. Male flagellum 10-segmented.

Neotropical hosts. Psocodea .
