OMYOMYMAR Schauff, 1983

( Figs 218–230 )

Omyomymar Schauff, 1983: 544 . Type species: Paranaphoidea silvana Ogloblin, 1935 , by original designation. See Huber et al. (2020) for the generic synonym and its type species.

Diagnosis. Face with faint or without subantennal sulcus ventral to each torulus and a median sulcus extending ventrally from transverse trabecula to about dorsal margin of a torulus; torulus about 1.4× its own height from transverse trabecula ( Figs 218a , 224a ); mandibles short, their apices not or barely extending to each other when closed ( Figs 218a , 224a ); gena in lateral view short; clava 2-segmented, the apical segment with a nipple-like projection in O. ( Omyomymar ) ( Fig. 219 ) or with a slight apical constriction in O. ( Caenomymar ) ( Fig. 226 ); ovipositor usually distinctly exserted beyond apex of gaster ( Figs 223 , 229 ), basally forming a huge loop inside gaster of O. ( Caenomymar ) ( Fig. 230 ). Male flagellum 11-segmented ( Fig. 227 ); mandibles large, crossing when closed, with 2 distinct ventral teeth of equal size and a wide, apically serrate dorsal tooth ( Fig. 225 ); scape with inner surface with a few to many spine-like projections in O. ( Omyomymar ) or transversely striate in O. ( Caenomymar ) ( Fig. 225 ).

Remarks. Omyomymar belongs to the Anagrus group of genera. The strongly dimorphic head also occurs in Krokella ; in both genera the mandibles are very different between the sexes. Caenomymar is at present a synonym of Omyomymar but its species could perhaps best be classified informally in a separate species group from those in O. ( Omyomymar ); O. ( Caenomymar ) species are larger than those in O. ( Omyomymar ) and the clava does not have a distinct apical nipple.

Neotropical hosts. Unknown.
