Si può andare oltre il genere?

This is a member of the genus Strumigenys. Two species are very similar and possible to identification with our key:

4. Hairs on clypeal dorsum narrowly spatulate; in profile the hairs distinctly anteriorly curved
or anteriorly arched (Fig. 265.3) .......................................... S. tenuipilis (Emery), p. 421
─. Hairs on clypeal dorsum simple, fine and cylindrical throughout their length and tapered
or truncated apically; in profile the hairs mostly straight, inclined anteriorly (Fig. 266.3) ..
.............................................................................................. S. tenuissima (Brown), p. 42

Thanks Lech! I'd say S. tenuissima, what do you think?

For me rather S. tenuipilis, clypeal setae are distinctly arched. Compare photos of head on AntWeb page:

and
https://www.antweb.org/bigPicture.do?na ... h&number=1

In S. tenuissima clypeal setae are predominantly thin and straight.

Great! Thanks a lot!
