DICOPOMORPHA Ogloblin, 1955

( Figs 107–111 )

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

Diagnosis. Occiput without lines, sulci or carinae except for a median transverse sulcus of variable length ( Fig. 107b ) just above foramen; mandibles when closed overlapping medially ( Fig. 107 ), each with 2 small apparently equal teeth; female antenna with funicle 7-segmented and fu 2 about equal to fu 1 or fu 3 ( Fig. 108 ); fore wing behind venation with posterior margin forming a slight but distinct lobe ( Fig. 109 ).

Discussion. Dicopomorpha belongs to the Alaptus group of genera. In the Afrotropical region this group also includes Alaptus , Callodicopus , Dicopus and Litus . Dicopomorpha appears to be most similar to Callodicopus but the vertexal trabecula is absent. Dicopomorpha differs from Dicopus by the head ventral to lower eye margin quadrate, not narrowing so appreciably ventral to eyes ( Fig. 107 ), the mandibles crossing medially when closed, and the fore wing just distal to venation wider.

Afrotropical hosts. Unknown.
