Following Krcmar et al (2011) Horse flies key of Croatia who is based on Chvála et al. (1972) and also Portillo-Rubio (2002) Fauna Iberica Tabanidae Key, they use, for instance some characteristics which I found really ambiguous: - Antenna: All antenna seen from both species are orange or pale brown in the basal segment and dark in the apical ones. - Abdomen colour is brown with a black median line wihich is more or less narrow or wide.. I have not seen nothing written about a rate. There are a few pictures of what I would call authentic P. graeca, with the tooth pointing really forwards and very narrow black line on abdomen: Krcmar et al (2011) has some "good" graeca specimens: rafael_carbonell attached the following image: [8.98Kb] Edited by rafael_carbonell on 15-07-2018 14:59

Graeca is much more golden, antenna nearly completely orange in in lateral view antenna segment 3 much broader. All relztive to aprica. Moreover, both species hardly (if ever) overlap in distribution: aprica is in the mountians, graeca much more confined to warm lowlands. For instance: any Philipomyia from Asturias is bound to be aprica. Theo
