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).
