Well, this is a bit more complicated... This species is surely not latiusculus/nigrifrons, very different genitalia etc...
This is a very distinct group of robust Nemotelus species, with very characteristic genitalia and antennae. The first species described is insularis Becker, 1908 from teh Canary islands. This one has the most hairs on the eyes, then there is freidbergi Lindner 1975 from Israel, which got wrongly synonymized with perplexus and then with latiusculus. The next species is cylindricornis from Spain and later Mason described danielssoni from Crete. The genitalia are more or less the same, the differences is the amount of setae on the eyes (cylindricornis is nearly bare) and the length of the snout, and maybe the color of the pronotal callus. I have a bunch of material from all over the Mediterranean, but never could make up my mind if this is one variable species, or different distinct species. Carles-Tolra (2001) reported danielssoni for the first time from Spain, together with cylindricornis. As far as I can tell from the paper, there was no indication how these species were differentiated... I usually went with the geography, if it si from the Canary islands, I call it insularis, from Israel Freidbergi and from Spain cylindricornis... N insularis and cylindricornis have a short snout, while danielssoni and freidberg have a clearly longer snout. But this character shows variation in the genus Nemotelus. Sorry, might not be the asnwer you were looking for ;-)
