Stratiomyidae? Xylophagidae? A very elegant and sizable fly. Did not get any response for this on the Japanese diptera forum. |

It has the feel of Rhagionidae. If you can get Nagatomi to have a look at it...

The wing venation indeed looks like those of other Rhagionidae species. http://xespok.net...1000026144 But the jizz of this fly was drasticly different. Also this is a giant species compaeref with others. But I observed only Chrysospilus and Rhagio spp. so far, at least as far as my identified Rhagionidae are concerned. But there are around 5-6 more smaller genera around in Honshu. |

I know there were a number of papers a few years back and I have not heard that he died.

Could this be Coenomyiidae? I have never seen a fly of this family (in a collection or live). They should be rhagionid-like but larger on average (around 2 cm for many genera). Illustrations in Vol 2 of the Key to the insects of Russian Far East show similar general habitus and wing & thorax pattern. But similar characters are also found in other related families (Athericidae, Xylomyidae in addition to those mentioned above). Nagatomi & Saigusa have published a paper on Japanese Coenomyiidae in 1970 (Mem. Fac. Agr. Kagashima Univ. Vol 7:257-292). Perhaps you could find this paper? No, I don't read Russian  , I have the Keys for the illustrations alone. This is very unfortunate since much of the literature for our nice taiga/tundra zone flies is in Russian.

http://www.pref.e...970_4.html http://home.hccne...ENO_NW.HTM The only two images I could find of Coenomyiidae. They look quite different. In Japan there are seven described species: http://furumusi.a...5%D6%B2%CA Hardly anyting can be found on any of these flies on the net. |

There is not too much info on Xylomyiidae, but what I found out so far looks much better: http://cedarcreek...002ap.html http://www.museum...ologie.htm The list of species in Japan: http://furumusi.a...5%ad%b2%ca Solva spp. look quite different, but Xylomya spp look rather similar. I think we are getting closert to this. |
