Question on tachinid names

Hello

Looking on the database for Tachina magnicornis I came up with Phryxe magnicornis.

Is Phryxe magnicornis now the accepted name for this species? I noticed it was in sub-family Exoristinae slightly un-expected, perhaps it was moved from Sub Family Tachininae for some reason (see http://www.faunaeur.org/full_results.php?id=144880)

Hope you can help

I don't think T. maginicornis is on the UK checklist? Perhaps that explains why you can't fnd it? Have a look at the UK Tachinids website to see if it mentions T maginicornis.

Re: Question on tachinid names

Fauna Europaea does not mention T. magnicornis for the UK...

Re: Question on tachinid names

Sorry for reviving an old thread but Tachina magnicornis is not a UK species - yet, but that doesn't mean that I don't look out for it. According to Theo Zeegers we should be wary of "T.fera" on sandy habitats. wink

Phryxe magnicornis is of course a different species - one of the rarer Phryxe spp. smile

Re: Question on tachinid names

Is T. magnicornis in your draft key? If not, what distinguishes it from T. fera?

Re: Question on tachinid names

Sorry for the delay in getting back to this thread. Tachina magnicornis is in the new keys - it was recorded from the Channel Isles this year, so it qualifies wink

Tachina magnicornis will be difficult to split from Tachina fera in the field but probably no more difficult than trying to distinguish Eristalis pertenax from Eristalis tenax. Basically, Tachina magnicornis has dark front tarsi - often black but sometimes dark brown (which can be marginal when compared to T.fera that have darker tarsi) and they have a wider frons, when compared to the width of an eye. This is another feature that isn't very easy in the field (because females have a wider frons than the males anyway) but I think it should be possible to be fairly sure that you are looking at a T.magnicornis with some practice.

I have plenty of specimens from mainland Europe and they do stand out fairly well. I will put more photos of them on the website at some point smile
