Found this diptera, I think they are male and female of Chironomidae, but I don't know what genus and specie. Someone could help me to identificate it? 05.11.2012 - Northeast Italy (Padua)   Thanks for the help Marcello Edited by Marcello on 06-11-2012 21:13 http://www.flickr...loconsolo/ |

Chironomini. They could be Chironomus. I can't tell. |

Yes, I think so, btw in Italy we have there species: Chironomus (Chironomus) acerbiphilus Tokunaga 1939 Chironomus (Chironomus) annularius Meigen 1818 Chironomus (Chironomus) anthracinus Zetterstedt 1860 Chironomus (Chironomus) bernensis Kloetzli 1973 Chironomus (Chironomus) calipterus Kieffer 1908 Chironomus (Chironomus) cingulatus Meigen 1830 Chironomus (Chironomus) commutatus Keyl 1960 Chironomus (Chironomus) dorsalis Andersen 1949 Chironomus (Chironomus) lacunarius Wuelker 1973 Chironomus (Chironomus) luridus Strenzke 1959 Chironomus (Chironomus) melanotus Keyl 1961 Chironomus (Chironomus) muratensis Ryser, Scholl & Wuelker 1983 Chironomus (Chironomus) nuditarsis Keyl 1961 Chironomus (Chironomus) nudiventris Ryser, Scholl & Wuelker 1983 Chironomus (Chironomus) obtusidens Goetghebuer 1921 Chironomus (Chironomus) pallidivittatus Edwards 1929 Chironomus (Chironomus) plumosus (Linnaeus 1758) Chironomus (Chironomus) riparius Meigen 1804 Chironomus (Chironomus) salinarius Kieffer 1915 Chironomus (Chironomus) tentans Fabricius 1805 Chironomus (Lobochironomus) dorsalis Meigen 1818 John Carr wrote:

It's not Chironomus anthracinus (black) or C. tentans or pallidivittatus (big genitalia). The last two are in subgenus Camptochironomus. C. tentans looks identical to the C. dilutus in the gallery; they were formerly considered a single species, with pallidivittatus Malloch a color variant. The European species C. pallidivittatus Edwards, 1929 is probably not the same as the American C. pallidivittatus Malloch, 1915, but they are structurally similar. |

Thanks for your help, I'm not so expert  I can only say what are the specie in my zone/city: Chironomus (Camptochironomus) Kieffer, 1918 Chironomus (Camptochironomus) pallidivittatus (Malloch, 1915) (N) Chironomus (Chironomus) Meigen, 1803 Chironomus (Chironomus) annularius Auct. (nec De Geer, 1776) (N) Chironomus (Chironomus) anthracinus Zetterstedt, 1860 (N) Chironomus (Chironomus) calipterus Kieffer, 1908 (N) Chironomus (Chironomus) cingulatus Meigen, 1830 (N) Chironomus (Chironomus) dorsalis Auct. (nec Meigen, 1818) (N) Chironomus (Chironomus) melanotus Keyl, 1961 (N) Chironomus (Chironomus) obtusidens Goetghebuer, 1921 (N) Chironomus (Chironomus) plumosus (Linnaeus, 1758) (N, S) Chironomus (Chironomus) riparius Meigen, 1804 (N, S) Chironomus (Chironomus) salinarius Kieffer, 1915 (N, S, Si, Sa) The most common are: Chironomus (Chironomus) plumosus (Linnaeus, 1758) (N, S) Chironomus (Chironomus) riparius Meigen, 1804 (N, S) Chironomus (Chironomus) salinarius Kieffer, 1915 (N, S, Si, Sa) I think it's one of this ..

Chironomus plumosus and some of the others would have a long "beard" on the fore tarsi which I don't see here. ID by elimination is problematic in subgenus Chironomus. Incompletely known species complexes are common. The situation in North America is described here: http://www.geneti...hiron.html. If you read John Epler's key to larvae of the Southeast United States you will find the majority of species in some genera are undescribed, and he doesn't try to resolve all the unknown species of the C. decorus group. Your best chance for an ID of Chironomini is to take a closeup of male genitalia. See my pictures in the gallery. Combining general appearance, form of genitalia, shape of pronotum, and size of frontal tubercles (between antennae) many genera and a few species can be identified. |

Yes, I know John Epler, he helped me just one time to identificate a subject by email I saw your shots in the gallery, wow, really awesome! Do you use a MP65E? BTW, the last chance I have is to post a genitalia zoom of the shot, I cleaned the 'image as best I could ... And .. thanks for all the help!
