Trying to find another species than B. vulgaris, here is my next approach: Rather small (in comparison to another Bellardia), with a dark spot at the parafacialia. However, the lower calypter does not look obviously darker than the upper one. I don't have a key, just putting together what various sources say. Could this be B. bayeri?

Hi Lorin, with the dark spots on the upper part of the parafacial I think you're right with B. bayeri. Eric |

Thanks, Eric! I think Stephane Lebrun has quite some experience, hopefully he will have a look in the forum again soon.

If someone could provide me with just the part where Bellardia is keyed out, that would be great!

Hello, keys to Calliphoridae are not always reliable. Calliphoridae can be difficult for many reasons. Some features can be variable, one may come across a freak specimen and members of a genus can be quite similar, as in vulgaris and viarum. Most of the time, you do not provide photos useful for keys. e.g. fore tibia, calypters, posterior spiracle, thorax, head, arista, abdomen, wing and genitalia (not always necessary but best for a positive id). i have to admit that i've misinterpreted a description from Dr. Rognes. Probably because i'm usually tired and i'm not so interested in Bellardia. Turns out, that the discal setae is just that - setae! I am incorrect with a concept of bristles. Therefore, i will need to reevaluate my opinions about Bellardia. So keep in mind that the discals are setae (hairs) not thick hairs (bristles). For this species, the calypters appear to be infuscated and the wing also appears to be infuscated. bayeri is an option but you need to view the head from above because any spot will not disappear when viewed from above if it is bayeri. show us the photo from above. Note: if you have trouble dissecting genitalia, then perhaps just try to show photos of it in dorsal and lateral views. John and Nini. Naturalists not experts. |
