My specimen posted here is close to Margites minutulus Holzschuh 2008 however are there are distinctions as well: unlike M. minutulus the pronotum is narrowed anteriorly and lateral side of pronotum is more distinctly rounded...is it different?
... described on the basis of three males; your is a female... However, it does not seem the same species: your is too narrow to be the female of minutulus.
