Aulacigaster perhaps ?
Thank you,

Family Sphaeroceridae! Please look at the typical shortened first tarsomere of the hind leg and the reduced chaetotaxy.

Ah yes ! seen! Thank you !
And for the species, according to the habitus, it could well be Sphaerocera monilis ?

Hi Guenael,

And only one species has the white frontal tarsae; Sphaerocera monilis Haliday, 1836. Judging by the tip of the abdomen, its a male.

Greetings,
Ectemnius
