Ciao Cosmin!  Congratulations!  Species with very interesting bionomy. In Poland and Ukraine it occurs in burrows of speckled ground squirrel (Spermophilus suslicus) - see photos.

I forgot to complimment Cosmin for these photos: the shine of surface of these beetles is good, much better than in the past! Very good work, Cosmin!

Ciao Daniel, thank you, now have changed the lights and I'm very happy with this combination. AetherisIgnis ha scritto: So strange black-winged rotundangulus... Why? The small series that I have collected was mostly blackish, on few of the specimens where brownish.

I have seen also tens of specimens from Ukraine and all were with elytra black or dark brown. See also my photo of Polish specimens. |

Thank all of you! Yes, I'm sure of that. This species was described from Eastern Ukraine (Kharkov), and original description says that it has brown-red elytra. I'll take a photo of my specimens when I return to Saint Petersburg. |

Dear Алексей, Thank You very much for Your very interesting photos! I think your Orodaliscus might be different species, distinct of rotundangulus, maybe new taxon! I've seen Ukrainian specimens od A. rotundangulus collected by Oleg Novikov and all had the same habitus as my and Cosmin's specimens (black or deep brown elytra)! Do You know Oleg Novikow? Show him Your specimens! A. spalacophilus is currently in the subgenus Pseudacrossus, not Orodaliscus (see e.g. Dellacasa & Dellacasa in: Löbl & Smetana 2006: Catalogue of Palearctic Coleoptera, Vol. 3). |
