I would agree with Nikita Vikhrev that it is a ephydrid. Not based on the shape of the antennae but based on the pecinate only on the dorsal surface (At least this is what I saw on the images).

You might be right. I just found an illustration of Rhynchopsilopa nitidissima in the Contributions to a manual of Palaearctic Diptera. that one also has elongate mouthparts. that Manual mentions only that species from the Middle East. i'll keep digging.

I had asked Wayne Mathis about this fly, and he agreed that it is an ephydrid, also pointing out it's similarity to Rhychopsilopa! I think that is a mainly African genus, but that doesn't mean there isn't something similar in China - maybe not the same genus, but similar.

in Literature, two Rhychopsilopa recorded in China:

Rhychopsilopa longicornis Haliday,1966 Fujian
Rhychopsilopa magnicornis Hendel,1913 Taiwan

as we can see... the behavio(u)r can be diverse and, sometimes, unexpected. Smile So this must be a "no self-respecting ephydrid" Grin AS our Tony Irwin told! Smile
"Bad girl" this fly. Smile

Which are the other possibilities besides Rhychopsilopa genus?

I just received 3 Eppendorf tubes with specimens from three localities and they appear to be Rhynchopsilopa. On one locality there are at least two species present, one with completely yellow legs and one with partly darkened legs. These differences are accompanied by differences in the male genitalia. There even might be a third species from another locality (also with partly darkened legs). The genitalia in these specimens are not so extended as in the other dark-legged specimens and I cannot be certain if that is significant or not. I'll be in touch. Wink

BTW: Rhynchopsilopa longicornis Haliday, 1966 should be Lissodrosophila longicornis Okada, 1966. I will try to find the differences between the two genera.
Further, there are 20 described species of Rhynchopsilopa, most of which are recorded from Africa. One sp[ecies is know from the Middle East, one from Sri Lanka, and another (magnicornis) is know from Indo-China, the Malaysian Archipelago and Taiwan. The 'twentieth' species is one of uncertain status from Indonesia.

Since this thread was posted 15 years ago, a revision of Chinese Rhynchopsilopa was published in Zookeys: https://doi.org/1...s.216.3224.

Zhang et al. 2012. A review of the species of Rhynchopsilopa Hendel from China (Diptera, Ephydridae).

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
