Is this Tachinidae? Malaise trap, Townsville, Australia.

---

Yes, that's a tachinid - I'd need to see the specimen for real to have a chance of keying it :)

---

Thanks Chris.
Cheers, Graeme

Same here, I can't confirm Australian, but Tachinidae it is.
Clearly somewhere in the Goniini / Eryciini vicinity

From the fact that there are 3 strong pre-alar bristles? :)

---

yes, it seems to be the most important clue.

Thanks ... I have always been most confused by the taxonomy of the Exoristinae and I am just starting to understand what to look for :D

Out of interest, could you recommend an article or database that gives the most up to date treatment of the genus+tribe+subfamily relationships? I am having problems finding how people in Europe are treating the Polideini :)

To quote Richard P. Feynman "They don't".
Polideini is hardly represented in the Palaearctic, as you know, more the Nearctic thing.

I think O'Hara's list of genera is the most modern thing (online on their website). Let me know if you can't find it.

Yes, I come across quite a few in the neotropical samples but I think, as far as the UK fauna is concerned, it's just Lypha and Lydina here ... but I just wanted to make sure that it was a generally accepted tribe because I'd like to update our checklist ;)
