Hi,

I found this fly on 14. July 2014 on island Rab (Croatia).

Ancylorhynchus sp. I will try later if it is possible to get to species level.

It seems to match with descriptions from O. Theodor about A. glaucius male

P.S.: just to signal that in croatian checklist there's no Ancylorhynchus spp. , butA. glaucius is the only one present in countries surrounding Croatia. I think that Ancylorhynchus cingulatus male is reliable.

Thank you both!

Should I keep there a "cf" or there are no very similar species? By the way, I didn´t find much information about ancylorhynchus spp. on internet, do you know some other good websites or good literature for asilids?

greetings, Martin

I think Valerio meant to say A. glaucius. A cingulatus is only known from Italy. Description of your fly fits A. glaucius. I would add a cf for i do not know what the current state of the genus is at the moment and if all species of eastern Europe are known. (Just lack of local experience)

Yes, glaucius. Dunno why I did typo cingulatus, sorry! :S Descriptions about glaucius male are perfect for this fly. About robberflies I think that also other genera are still incomplete, and bet that will appear new species, as soon as some decent deep studies will be made

I'd seen that. ; )

Ok I´ve seen that you wrote A.glaucius, but the last one was cingulatus, so I wasn´t sure :)

of course I will correct it...

Reinoud, this is a perfect A. glaucius (male) -- no need for the 'cf.' This is the type species of the large genus Ancylorhynchus (most species are found in Africa).

Martin, please add your beautiful image to the Diptera Gallery when you get the chance. Thanks, Eric.

Thank you Eric! Can you tell me wher i can find a more recent key to this genus? I have some Spanish specimens. (male ande female that are similar yet different collected on the same day and place. (sexual dimorphism?)

A. glaucius has relevant sexual dimorphism (legs, for example have different colours).

Reinoud,

There is a recent revision of the genus in tropical Africa (Londt, 2011 - A review of Afrotropical Ancylorhynchus...African Invertebrates 52: 471-556). The Palaearctic spp. must need revision; I don't know of any complete keys since Engel, 1930. My identification of A. glaucius was made by comparing specimens determined by M. Hradsky I have with the photo. I only have males, so can't describe the sexual dimorphism in the species, but there must be some.

Cheers,

Eric

Thank you Eric for the extra info, Valerio for your remarks and last but not least Martin for sharing these wonderful pictures!

With Engel my Spanish specimens key out to A. limbatus. The description doesn't fit too wel though. Differences between m and f are numerous.
