(Iberia: Girona province; Beuda: Riera de Rajolins: 380 masl; 2016 August the 2nd) As I can't get at the moment the Iberian Portillo keys I have followed Kroatian keys (Krcmar, et al, 2011). Unfortunately I didn't measure it. So I think we have to look at the hairs of the vertex (pale and dark in exclusus; black in glaucopis) and the subcallus (only apically polished in exclusus and completely polished in glaucopis)... but i dont' trust too much theses features.... Tabanus glaucopis is common in my area. Can anybody help? rafael_carbonell attached the following image: [245.93Kb] Edited by rafael_carbonell on 25-01-2023 23:38

And for future cases: please make the head shots strictly frontal and strictly lateral. these shots with oblique anglea are very hard to interpret. Thanks Theo

This does not fit any species in the glaucopis group, but rather suggests cordiger group. If ther would be one eyeband, the only option with a big head is leleani, which is definitely not Spanish. So I am lost. Did you happen to note the number of eyebands ? Theo

Member Location: Beuda, Girona, Catalonia Posts: 667 Joined: 23.03.06	I'm sorry Theo. Pictures don't help, and some parts were taken in shadow conditions. In the picture with green background the antenna don't look completely black. The subcallus looks polished in the upper part (i would suspect is more unpolished as it was freshly emerged). I thought this could help. I think the eyes in the lower part have at least three stripes. Next time I will collect it. rafael_carbonell attached the following image: [53.08Kb]

Member Location: Beuda, Girona, Catalonia Posts: 667 Joined: 23.03.06	We have had this discussion before (with a female Tabanus): http://www.diptera.info/forum/viewthread.php?forum_id=5&thread_id=54882 When you say "stout" do you mean thick? Or short? There are pictures on the web (some of the from this site) of "Tabanus glaucopis male" that look similar. But anyway all my specimens are smaller than they should. May be I can send them to you? All the best anyway, Rafael Edited by rafael_carbonell on 25-02-2017 12:26

Member Location: Soest, NL Posts: 18794 Joined: 21.07.04	I looked at it again. This is not glaucopis and I am pretty sure it is the male of leleani. This would, however, be the first record for Spain. Leleani is generally more eastern, but it has been recorded from Morocco. So, maybe this year you can find this species again and collected ! Would be a first for Spain. Theo
