Hello, Fine picture. Very fine picture. Just to be picky: how bad that we don't have the fore legs in full... Pierre Duhem |

Yes, a male Chironomiae. Species or genus is hardly possible. It is possibly within Chironomini.

Is it only possible, because the genetiaal must be examined? And when that is the case, is it possible that a good photo of the genetalion, can be sufficient?....or not? Greatings Joke |

Male gentialia MAY be sufficient for a genus if your are lucky. For species level often molecular methods, karyotyping, etc. is needed as far as I know. Recently I tried to Id a series (both males an females) of an extremely distinctive large (cc 6 mm) Chironomid species, and I got to around a group of genera within Tanypodinae. I had major problems understanding the key, and also my rather strong stereomicroscopes were insufficient to resolve some details to the extent necessary for seeing the right features (for example is the edge of mid tibilal spur (cc. 0.1-0,2 mm) covered with similarly large setae? ). So I think without a true microscope, and someone who is knowledgable, it is very challangeing to try to id Chironomids. Gabor Keresztes Japan Wildlife Gallery Carpathian Basin Wildlife Gallery |

Generally speaking a slide mount of the various critical parts (wings, legs, genitalia) is the only sure way to id chironomids: a lot depends on the key used as well - many countries have no recent key works. They are a pain, but worth the effort. |
