I found it in a cave entrance.
It seems to me to belong to the genus Pseudexechia. Is that the case ?
Thank you for the help.

For the time being it is going to be stored as
Exechiopsis (Exechiopsis) nr.
coremura. After first examination I ended up with two possible species but both of the scarce enough not to have been illustrated recently. In fact, the only illustrations of the genitalia were the ones in the original decsriptions (1928 and 1955, respectively) and not up to present day standards. After that I had a brief email exchange with Peter Chandler and he send me a reference specimen for one of the species,
E. coremura, from Spain. This specimen clearly fits the illustration provided by Edwards in 1928 (left). Your specimen closely resembles that species in general structure but there are some distinct differences. The inner median lobe of the gonostylus is much narrower than that in the
coremura specimen, the anterior setae on the ventral lobe of the gonostylus are somewhat thicker and more densly packerd and there are some differences on the complex of tergite IX and the cerci.
A possible alternative could be
Exechiopsis (Exechiopsis) oltenica but the illustration of the genitalia of that species (right) only show the ventral aspect and not the dorsal aspect (which should show the inner median lobe). Until I have seen a reference specimen for that species I cannot rule that one out.
