July 21, 2009, Naro-Fominsk, Moscow region, Russia. Roughly equal proportion of males and females (total number about 20) was found in a container with (mostly) lepidopteran pupae including a couple of Psychidae cases and some cocoons of Hypera collected on Galeopsis speciosa (weevils mostly already emerged). Size: male ca. 1.5 mm, female ca. 2 mm. Hosts of Necremnus include both Psychidae and Hypera, yet to me it looks more like Pnigalio.

Subject changed from Eulophinae, Necremnus/Pnigalio? to Elasmus, ID by proctoss.

Many thanks Victor, yes with branched antennae of male it seems to be Elasmus; typical big and flattened hind coxae are also quite visible, although some early authors (e.g. Nees and Foerster) took them for part of the thorax.

I've checked Graham, 1995 (The Entomologist's Monthly Magazine, Vol.131, 1-23) and think this might be E. flabellatus (Fonscolombe, 1832).
