wow! A beauty. How I would love to have this specimen. Walter, at the moment, the Ogcodes genus is in a mess... but so far there is no one that is studying this genus neither even Dra. Emilia. I'll try to dig out later the keys, if possible (busy now). |

Are the halters pale? If so, should be O. gibbosus. This looks fairly typical gibbosus, what comes to the descriptions in Lidner (by Pius Sack). Thereīs a world revision of Ogcodes by Schlinger (1961) in the Proceedings of the United States National Museum 111:227-336. Besides Lidner, the Chvala, M., 1980a. Two new European Ogcodes species (Diptera, Acroceridae). Acta ent. bohemoslovaca 77, 131-137. is a good reference for the genus. The "mess" is not as bad with the Palearctic species, but the trouble is that many of the species vary a lot (and they are rare). |

well, Jaako, I can tell you that Dr. Christian Kehlmaier told me once time: "I think that European Ogcodes is a real mess at the moment. Once there is sufficient material available for molecular studies, we'll hopefully find out more about their real diversity." So, it is important to someone dive in this genus to know without any doubts the species. |

Ok. I donīt know much about this extremely interesting family. However, I would not be surprised if it turned out to be rather species poor than rich. All parasites of spiders, restricted habitats (as far as known), low in numbers etc. It is easy to understand what governs the biodiversity in Tachinidae, but in Acroceridae? The complication to my impression is that the characters used in the older litterature vary in nature and due to lack of specimens nobody has really found out the borders of this variation.. Having said that, I have only O. nigripes from Finland, with which I had to struggle quite a lot, so thatīs all what comes to my personal qualifications... Luckily the Chavala (1980) has good descriptions of the known European species. Very interesting family indeed.. too bad that you collect these by luck only.  Best, Jaakko |

And see also the Dutch review by De Jong et al. (including... myself) in Entomologische Berichten. Indeed, with not all the answers Theo |
