Widespread in secondary vegetation near decaying organic. Look and act as very large (7-10mm) Sepsidae. I wouldn't be very much astonished if it is some crazy Muscidae.

Interesting. Reminds me of Tanypezidae but will 'think further'.

Dear Nikita, Tha last two photo's are not the same Family! The yellow and black species is a Tephritid, genus Dacus or Bactrocera, depending on whether you follow the splitters who devide the genus Dacus into several (sub)genera. I think that the first fly is either a Sepsidae or a Ulidiidae. John Edited by John Smit on 17-01-2006 09:05 |

Thank you John. Never image that Tephritidae may look like this! Nikita Nikita Vikhrev - Zool Museum of Moscow University |

I've got assumption about it from Andrey Ozerov that it may be Megamerinidae. According Ausnralian checklist: Megamerinidae are an enigmatic family comprising about 11 species in the genera Gobrya Walker, Megamerina Rondani, and Texara Walker. Syringogaster Cresson, formerly placed in this family, has been placed in its own family, Syringogastridae (Prado 1969), which is apparently an endemic Neotropical family. The immature biology of Megamerinidae is poorly known, but larvae have been recorded as living under bark or decaying vegetation. Gobrya, the only representative in the Australasian/Oceanian Regions, is primarily Oriental with an eastern extension into the Papuan Subregion. Colless & McAlpine (1970: 722) stated that Gobrya is erroneously referred to this family, but do not offer an alternative. McAlpine (1982  ascribes it to the Nothybidae and Ferrar (1987) treats it in the Syringogastridae. Until further phylogenetic studies are done to clarify its family placement, I follow Steyskal (1977 in placing it within the Megamerinidae.Nikita Nikita Vikhrev - Zool Museum of Moscow University |

Nikita - is the Australian Checklist you often quote available as a download off the web? You have obviously found it v useful, and I am off to central Australia in April. (I am, in fact, Australian born, but have lived in England for the last 10 years. When in Australia, I concentrated on butterflies, so know shamefully little about Australian diptera. It was only once I was in England and looking for something with a challenging degree of species diversity that I hit upon flies).

Thank you - that's my holiday reading sorted then. With any luck I will completely freak out the poor stranger who gets to sit next to me on the plane.

Don't worry. I was on the train many years back and we were with three dipterists and a 'stranger' in one compartment. We discussed the identification of lies and the word 'genitalia' was mentioned very often. We got a lot of funny looks and grins, but we were not arrested.

Nikita, Though I am not an expert, I have doubts about the first fly being a Megamerinid fly. My gut feeling is Platystomatidae. Megamerinid flys in theory should really more resemble Micropezid flies in structure. 4 images of a species of Megamerinidae from Japan |

Nikita, I agree withXespok, it really looks like a Platystomatidae and it is for sure not a Megamerinid. They have swollen hind femora and a more elongate abdomen... Cheers Martin Martin Hauser |

In the description of the Platystomatidae in The families of Diptera of the Malay Archipelago by Pjotr Oosterbroek I have not seen anything that would really contradict Platystomatidae.

Well, I'm only in position to listen. Anyway, I'm sure that correct ID will be finded, fly is collected and fly is rather common in very antropogenic places. Thank you all, Nikita. Nikita Vikhrev - Zool Museum of Moscow University |

Andrey Ozerov just told my that he has another idea concerning this fly - Platystomatidae. This time it seems that it is the final answer. I've found on http://bugguide.net/node/view/11999/bgpage Rivellia sp. identified by Paul himself. Same family, if not same genus, doesn't it? Nikita Vikhrev - Zool Museum of Moscow University |

Quite well possible, but I do not know the Oriental Rivellia. The ones I have seen (Holarctic) all had bands on the wing (like the onon bugguide) but the Oriental may be different. And... I had not realised that the mouthparts of those Nearctic ones were that big, too!

This fly does not look like a Rivellia to me, but I have no idea what extent of morphological variation this genus harbors. It does not look like any of the Rivellia species that I had seen in Japan.

Hi Xespok. Between your images collection it reminds Lamprophthalma. Diptera of Far East key also lead to this genus (shape, size - 8-9mm, bm-cu direction) with 10 sp. in Paleotropics. The only species in my key is L. japonica which is not the case obviosly. As for Rivellia, even in Russia Far East about ten species (found or possibly found). Size is OK (2-4mm), about species level Paul was right - difficult to say something. Nikita Vikhrev - Zool Museum of Moscow University |

Today I found image of same (I hope so) fly. Unfortunely I can't red the name of genera
