Hello! I think this Machimus group chrysitis fits well the general description of chrysitis and specially the shape of epandrium in lateral view (attending to descriptions and ilustrations of fortis given by Weinberg 2001 and chrysitis by Weinberg&Tsacas 1976) What do you think?

Well, it is at least a very close relative, this one seems to have entirely black femora in opposition to chrysitis which has partly red femora. But having said that, I tend to believe that the species is more variable than is accepted.

Thanks a lot Reinoud. I thought about chrysitis nigrofemoratus, but i wonder if the photo let us define the species. The epandrium seems to me quite curved un lateral view (chrysitis like) not paralled sided (fortis). Whats your opinion?. If confirmed the species It would be the first record in our local región. Regards. Eduardo |

This is very confusing group of species. There is a lot I could comment on but will not at this moment. M. c. nigrofemoratus is considered a valid subspecies and in my opinion this one fits the description of Strobl 1909 (which is very brief). Tomasovic stated that M. subdolus (which supposedly has also black femora!) is a synonym for M. chrysitis just to emphasize the confusion. One thing is sure, this specimen is very close to M. chrysitis (nigrofemoratus) and in my opinion a lot of work still has to be done.
