in Exoprosopa the spots on wings have more clear limits than Thyridanthrax? Is it correct? |

there is a problem... I have the specimen, and the sternites I and II are clearly brownish in color. it is not possible to be any artifact or loose of scales.. According to Seguy key this would be T. fenestratus. Another data: the halteres are all whitish. |

look at the squamae, whitish (perspicillaris) or blackish (fenestratus). wing pattern of Exoprosopa very variable, in some no real pattern at all |

squamae are clearly whitish. So T. perspicillaris. But the colour of sternites don't fit. Is it very variable? |
