but the picture is not clear.

I guess it is a Diopsidae, but which genus?

---

otitid perhaps?

---

Or Diopsidae ?

Jari

---

thanks, my friend. But it d:)oesn't belong to Diospidae.

---

Thinking along the line of Periscelididae but unfortunately I don't have any reference works covering the Oriental region here... Can you a manage a clearer view of the wing venation?

---

I am very curious then what family it is!

---

Paul seems right, probably Periscelididae. Last year I collected 2 specimens of this or very near flies in Thailand, Surat Thani prov, on shadow vegetation under small silty brook.
I gave its to Andrey Ozerv, but he currently interesting nothing exept Scathophogidae. Andrey, am I right or not?

---

Maybe Drosophilidae, something like Mulgravea asiatica (Okada, 1964)? Of similarities, lateral dark spots on mesonotum match quite well.

---

I have not been able to locate an image of Mulgravea on the net (at least in the image search) and my papers do not cover the genus. The images above are not nearly clear enough to show the head setae, but either that or the wing venation should make things a lot clearer.

---

I took another series of photos,
wing C with two broken, anal nearly absent,
male genetalia: tips with a row of smallblack teeth

I check the key ,maybe Drosophilidae
give my sincere thanks to everyone here.

Black, I think you are right in Mulgravea (though I cannot see the chracteristic drosophilid fronto-orbaital setae), but it certainly is not asiatica, as that should have a completely black abdomen. None of the other species have been reported from China. De & Gupta (1995) described four species from Bhutan, but none of these fits the images above. The only remaining species described form the Asian continent ranipoorensis from India is a no-fit, too. Closest appears to be neoasiatica from the Malaysian Peninsula. So, might well be a new species. :D

Vasilij Sidorenko wrote me: This fly is one of few Drosophilidae with broaded head. Sometimes head may be normal. Distributed from Ryukyu to Java and Shri-Lanka. Mulgravea asiatica (Okada, 1964).

---

As is clear from the first and fourth image in the thread. Can Vasilij then confirm that this species is variable in this respect? If so, the key provided by De & Gupta (1995)uses an invalid character to separate asiatica and neoasiatica..

---

I think you are now better expert for you have checked species-keys.
Who will descibe new species?????;)

---

thank you very much.
only a specimen(male),so I will collect more specimens and then have a chance to describe and illustrate them. But now I concentrate on Lauxaniidae

:)

V.Sidorenko wrote that he had seen many material of M.asiatica from Taiwan. Neoasiatica differs from it by description – it is smaller and head metallic-blue. As for coloration of abdomen – this character vary. It may be light in young specimens and dark in others. He couldn’t write himself for his address is blocked. I hope I am good interpreter.

Thanks!

Dear Cranefly, take my sincere thanks to V.Sidorenko.
Express thanks to everyone here.
When I am free, I will take a beatiful and clear photo for the specimens, and then keep it in gallery.
I give thanks to Paul, an excellent administrator:)
