POLYNEMULA Ogloblin, 1967

( Figs 271–276 )

Polynemula Ogloblin, 1967: 190 . Type species: Polynemula rufosignata Ogloblin, 1967 , by original designation.

Diagnosis. Face without subantennal sulcus ventral to each torulus, with pit medially next to medial margin of each torulus and toruli separated by about 2× their own height from transverse trabecula ( Fig. 272 ); propleura abutting each other anterior to prosternum; propodeum with 2 parallel submedian carinae diverging anteriorly (best seen in lateral view) and joined by a weaker transverse carina near anterior margin of propodeum ( Fig. 276 ); petiole apparently attached to gt 1 ( Fig. 275 ); ovipositor enclosed in gastral sac and strongly extending anteriorly to level of midpoint of mesosoma and also projecting posteriorly distinctly beyond apex of gaster ( Fig. 275 ).

Remarks. Polynemula belongs to the Polynema group of genera. It is most similar to Kalopolynema in having subantennal sulci ( Triapitsyn & Berezovskiy 2002) and to Platypolynema in having the ovipositor extending anteriorly ventral to the mesosoma. The combination of absent subantennal sulci and anteriorly extending ovipositor distinguishes Polynemula from Kalopolynema and Platypolynema . It also shares with Platyfrons a similar set of submedian carinae joined by a transverse carina.

Neotropical hosts. Unknown.
