DICOPOMORPHA Ogloblin, 1955

( Figs 109–113 )

Dicopomorpha Ogloblin, 1955c: 387 . Type species: Dicopomorpha macrocephala Ogloblin, 1955 , by original designation. See Huber et al. (2020) for generic synonyms and their type species.

Diagnosis. Face with toruli separated by almost 2× their height from transverse trabecula ( Fig. 109a ); occiput without lines, sulci or carinae except for postorbital sulcus of variable length ( Fig. 109b ) just dorsal to foramen; mandibles when closed overlapping medially, each with 2 small apparently equal teeth ( Fig. 109 ); funicle 7-segmented with fu 2 shorter than fu 1 or fu 3 ( Fig. 110 ); fore wing behind venation with posterior margin forming a slight but distinct lobe ( Fig. 111 ); genitalia greater than half metasoma length ( Fig. 113b ).

Remarks. Dicopomorpha belongs to the Alaptus group of genera. Dicopomorpha appears to be most similar to

Callodicopus but the vertexal trabecula is absent. Dicopomorpha differs from Dicopus by the mandibles crossing medially when closed, the head ventral to lower eye margin not narrowing so appreciably, and the fore wing just distal to venation wider. Male flagellum 9-segmented.

Neotropical hosts. Unknown.
