This Tabanidae was flying at the window where it was collected

Locality: Iberian peninsula: Catalonia: Girona province: Beuda: 31T DG77: 395 masl
Date: 28/06/2014
Habitat: Inside house in an stone oak wood + crops environment
Sex: Female
Size: 17.5 mm

It has three bands on eyes when hydrated
The problem is that using Fauna Iberica keys (Portillo-Rubio, 2002), the frontal index should be 1:6, and my measurements are about 1:4* (measured again in 2016, the frontal index is 102/19=5.4)

Thanks in advance,


PD. A month later another Tabanus was seen on similar conditions:

I think no other similar Tabanus with three eyebands lives in Europe, so for me your ID is correct.

Some flies preserved in ethanol and then pinned often get the eyes sunken, how can this be avoided? Best answer: I usually keep alcohol-collected material in alcohol

Yes, dipterologists from far abroad, please buy your copy at veldshop. Stamps will be expensive, but he, the book is unreasonably cheap Smile
