Hello, I want to ask about genus Siphona. Following Andersen, only rossica, setosa and grandistylum may have setulae on vein R1. First two have strong dorsal marginal setae on T2 and the third one is a rare montine species. Both charecters are absent in my specimens, nevertheless, they have setulae on R1. So, is this character is rather variable? neprisikiski attached the following image:  [163.5Kb] Edited by neprisikiski on 16-07-2009 23:25 Erikas |

The feature is variable, however, if it is present, like here, it is very special. Could we get a lateral headshot, proboscis included ? And of the base of the wing, from front (to see the epaulette) Thanks Theo |

Proboscis of the first specimen is on the side, so lateral shot cannot help. I attach next specimen here below, it is female

Thanks, that helps. Proboscis is too long for grandistyla, I'd say. So next please the epaulette, or just describe its colour, please Theo |

Oh, and what about DC bristles on thorax, 3+3 or 3+4. If 4, are the middle 2 close together ? Theo |

I'm a bit reluctant to confirm grandistyla without having seen the specimen myself. With this reservation in mind, I do agree grandistyla seems to be the only possibility, given the features on the pictures and the ones you have mentioned. If you could share a specimen, I'd be more certain. Theo |
