A question. Same fly/individual but anorther photo. Why this difference between the antennas? The other Picture is from the Swedish "Artfakta" https://artfakta.se/artbestamning/taxon/panzeria-rudis-200231?fbclid=IwAR1EbLwjUdAyCC9iu1cjJdp_3RmXlld3QT2u_4EQfWruv6-ItEKS8IzBy5U |

Interesting question. Rudis has a very rare lookalike P. vagans. Difference is easy on male genitalia, but otherwise difficult. I dismissed this option based on the thoracic pattern in the first pic. The second pic shows strong darkening on anterior part of scutellum, a feature suggesting vagans. So I need to look into this. * Can you tell whether hairs on eye are darker on upper half ? * Can you tell whether abdominal tergites have lateral discal bristles ? Thanks Theo |

Hi again I have now looked again on my fly. Here are the answers to Theo's two qustions: I can't see any difference in the colour of the hair in the eyes, they all seems to have a brown-yellow tone. There are no discal bristels on the tergits. /Martin |

So, both are rudis ! So, I checked my collecting. The antenna in Panzeria rudis is surprisingly variable , Your second male is the macho type with dark antenna, only some brown at base of third segment, and borad third antennal segment. Your first is a feminine male, with lots of yellow, also on basal segments, and narrow third segment. Your two cases represent more or less both extremes, but many are intermediate. Of course, this is based on Central European material and I would need to study the genitalia to be very sure. (I found a cryptic new species in Russian Far East). But for now, it really is Panzeria rudis, both of them ! note that a similar situation, far more extreme, occurs in Phasia and Ectophasia. Theo |
