XENOPOLYNEMA Ogloblin, 1960

( Figs 345–349 )

Xenopolynema Ogloblin, 1960a: 9 . Type species: Xenopolynema areolatum Ogloblin, 1960 , by original designation.

Diagnosis. Face without subantennal sulcus ventral to each torulus, with a pit medially next to each torulus and toruli separated by about their own height from transverse trabecula ( Fig. 345a ); propleura widely abutting medially anterior to prosternum; fore wing with a narrow dark transverse band posterior to venation; parastigma lengthened, slightly separated from anterior margin of wing, and marginal vein apparently absent ( Fig. 347 ); propodeum submedially with 2 curved carina meeting dorsally, forming an oval median area ( Fig. 348 ); petiole attached posteriorly to gs 1 ( Fig. 349 ).

Remarks. Xenopolynema belongs to the Polynema group of genera. Among the Neotropical genera, Xenopolynema appears superficially to be most similar to Vladimir based on the more or less lengthened parastigma (+ marginal vein, when present) + stigmal veins and the dark transverse band posterior to these but instead is most similar to the Australasian genus Boccacciomymar Triapitsyn & Berezovskiy.

Neotropical hosts. Unknown.

Important reference. Ogloblin (1960a).
