At high altitude ? Did you consider genera like Masistylum / Masistyloides ? Theo |

The altitude is low 600 m. Masystylum I have it in collection, it's something else. I'm looking for info about the genus Ceratochaetops |

Ah ! Could you please make a dorsal oicture ? Male Ceratochaetops have a very narrow central line of adpressed hairs on tergites, similar to Clemelis. That should be a vig clue. The vertex shoukd be extremely broad. Theo |

The vertex is broad, but the central line of pressed hairs is weakly visible and depends on the angle of vision. I have no description of this genus and keys to separate the two species. christoophe attached the following image: [193.52Kb] |

Yes, very nice indeed. Ceratochaetops it is. There are two - very similar - species. You don’t have Mesnil in Lindner, I guess ? (genus is hidden under Nilea) Theo |

Could we get a closeup of the scutellum ? Idem the head in frontal view ? Are the fore claws as long as last tarsal segment, or only half its length ? Theo |
