There seem to be sensilia on the second antennal segment. In that case the hairs on sternite 1 should be white (not black). Please check. Theo |

I don't see it, but I believe you. In that case, it is L. tessellans Theo |

Now, with a microscope, sternite 1 are with black hairs. By means of the key: -Back of the head on top without bristles. -Tergites 3 and 4 with one pair of discal bristles each. christoophe attached the following image:  [89.22Kb] |

-Humeral callus ± reddish or yellowish, at least around the area of the outer humeral bristle. Posterior edge of tergite 5 often with a reddish seam. -Mouth edge less strongly pulled forward (by about the width of the 2nd antennal segment at its end). christoophe attached the following image:  [89.93Kb] |

-Humeral callus predominantly yellow. Tibiae yellowish. Now, I think L. olsufjevi. christoophe attached the following image:  [75.92Kb] Edited by christoophe on 12-11-2010 19:40 |
