Dicopomorpha Ogloblin, 1955

Dicopomorpha Ogloblin, 1955: 387 .

Type species: Dicopomorpha macrocephala Ogloblin , by original designation.

Chromodicopus Ogloblin, 1955: 390 . Type species: Chromodicopus pulchricornis Ogloblin , by original designation. Synonymy by Yoshimoto, 1990: 27.

Dicopulus Ogloblin, 1955: 377 . Type species: Dicopulus stramineus Ogloblin , by original designation. Synonymy by Yoshimoto, 1990: 27.

Diagnosis. FEMALE. Funicle 7-segmented (e.g. Fig. 9 ) or rarely 6-segmented (e.g. Fig. 3 ), but clava entire; mandibles bidentate and when closed crossing over each other medially; fore wing relatively narrow, with posterior margin slightly curved towards apex but relatively straight medially (e.g. Figs 1 , 6 ); metasoma broadly sessile; tarsi 5-segmented ( Lin et al. 2007).
