Hybotidae, could be Leptopeza. Any other views?

Thank you Paul. I only have one more photo of this specimen (not a very good one). I have also photographed a male, but I'm not sure if it belongs to the same species. Are those eggs what we can see throw the female's abdomen?

Oropezella sphenoptera, both, but if you kept the specimens I'd be happy to check if it might be a new species. Normally there would be more yellow on sphenoptera specimens.

Thanks again:). I have one specimen (a female). I guess that a male will be needed for a proper identification...If I manage to find a male I'll send it to you.

I received the specimens today, and lo and behold: Oropezella sphenoptera. I compared them with Chvála's description in the Fauna Ent. Scand. book (1983) and two specimens I have from Greece. Though there are some subtle differences between these Portugese and Greek specimens, there is nothing to really indicate they are another species than the one described by Chvála. The main differences are in colouration and that may also be influences by the relative ages that the specimens were collected. Some of the additional Portugese specimens, other than the female illustrated above, illustrated the paler parts on the thorax as Chvála mentions to be 'often' present.

Thanks for sending some pristine specimens, Rui!

Thank you Paul! When I saw the specimens on the magnifying lens I noticed the legs were more yellow than what appeared on the photos. For this reason I began to suspect that it was O. sphenoptera:). I believe the darker coloration of the legs on the photos is a trick of light.

Can you confirm if this is a male Oropezella sphenoptera? It was photographed today in Barcelos, Portugal.
