Absyrtus vernalis Bauer, 1961 View in CoL (Fig. 31 A–B)
Belonging to the tribe of Perilissini , the glymmae are present (relatively deep) and the claws are pectinate. Distinguishing this genus from other testaceous Ctenopelmatinae can be done on the basis of the wing venation. The fore wing has the discosubmarginal cell uniformly setose, lacking sclerites, and the fore wing AA is bent downward into this cell ( TOWNES, 1970b; BROAD, 2012; see Fig. 31 A).
In theory A. vernalis can be distinguished from A. vicinator (Thunberg, 1824) by its matt propodeum with a complete carination (Fig. 31 B) and the fore wing vein cu-a, which is widely separated from M. On some of our specimens, however, we noted how the carination of propodeum is variable and sometimes only shallow. This diagnostic feature should thus be treated with care to distinguish the species. Lastly, A. vernalis is a known parasitoid of several common sawflies of the genus Macrophya (Symphyta: Tenthredinidae ) (AUBERT, 2000).
