This small Asilid with spoted wings in males is very common all over Tanzania in places where I look for Lispe: banks with fresh, brackish or salt water. Is it several resembled species or one commen species? If one species, name please! Nikita Vikhrev - Zool Museum of Moscow University |

This is Stichopgon punctum Loew, one of 8 species known from Africa in 1979 (Londt). S. punctum is only African sp. with conspicuous black spot near wing tip. Cheers, Eric |

Thank you, Eric, I have a large series, now it has name. I forgot to write that not only water from fresh to salt, but also altitudes from 0 to 1500 m asl. One more species of Stichopogon is on sea shore: very large for Stichopogon and very difficult to catch, I have so far only 1 specimen.

Sounds like your large Stichopogonini may be a Clinopogon (in fact, C. nicobarensis (Schiner)). PM sent. Cheers, Eric |

Dear Eric, according to the key you sent me, it seems to be C. nicobarensis. But glance a look, please. Nikita Vikhrev - Zool Museum of Moscow University |

Yes, definitely a Clinopogon sp. I believe the 'stalked-4th post. cell' character used by Londt works only for certain Stichopogon s.l. (e.g. African ones; many exceptions for other areas of world). Stichopogon is abundant world-wide, whereas Clinopogon is found only on sea beaches in the Old World tropics. Better character may be antenna: Clinopogon flagellum has small (inconspicuous) style at apex, Stichopogon with larger, more evident style (often angulate). [Can be seen in your photos]

Thank you, Eric. There are two possibilities: to send image in Gallery under C. nicobarensis (Schiner) or do not. What should I do in your opinion? Nikita Vikhrev - Zool Museum of Moscow University |

I'd suggest submitting the image as Clinopgon cf nicobarensis (Schiner), which should cover the identification well. This has been judged as the only valid Clinopogon sp. along the east coast of Africa by both Oldroyd (1974) and Londt (1979). According to Londt (Catalog of Afrotropical Afrotropical, 2005) there is also a Clinopogon reginaldi Seguy now known from minute 'Tromelin Island' (450 km east of Madagascar, in the Indian Ocean). The status of this mysterious oceanic sp. is not known to me. Another named Clinopogon (C. grossus Bromley) is considered to be a synonym of C. nicobarensis. |

Upps! One more question: of what sex the specimen is?

The Clinopogon is a female. Cheers, Eric |
