Hi,
I have a specimen of Tanyptera, but no key or descriptions of species. Can anyone advise how to separate the two species T atrata and T nigricornis?

(and I quote): Coxae and trochanters black; antennae black; male abd. tergites 2 + 3 reddish with continuous black median line =
nigricornis. Otherwise it's
atrata (obviously).
