NEPOLYNEMA Triapitsyn, 2014

( Figs 206–210 )

Nepolynema Triapitsyn, 2014a: 171 . Type species: Barypolynema grandis Taguchi , by original designation.

Diagnosis. Face without subantennal sulcus ventral to each torulus, without pit medially next to each torulus and toruli separated by their own height from transverse trabecula ( Fig. 206a ); propleura abutting each other anterior to prosternum; mesoscutum along each torulus and posteriorly on lateral lobe, and scutellum posterior to each campaniform sensillum with minute pits (likely glandular openings) ( Fig. 209 ); frenum extremely narrow, not separated from scutellum by row of punctures ( Fig. 209 ); fore wing with relatively long venation and parastigma distinct, together with stigma vein almost as long as submarginal vein ( Fig. 208 ); metasoma apparently attached to gt 1; propodeum without carinae ( Fig. 209 ). Male with flagellum over 2.5× as long as entire body, by far the longest of any species of Mymaridae .

Remarks. Nepolynema belongs to the Polynema group of genera. Its species occur at fairly high altitude (above 1000 m) in Central America. The minute pores on the mesoscutum and scutellum appear to be unique among New World Mymaridae . They also occur in the Old World genus Boudiennyia Girault but in a different configuration and on the scutellum only.

Neotropical hosts. Unknown.
