Thread subject: Diptera.info :: Vietnam Choerades?

According to Tomasovic & Bartolozzi “Contribution to the knowledge of the robber flies from Vietnam, with description of nine new species”, 2018, no Choerades species had previously been reported from Vietnam. https://www.academia.edu/82413107/Contribution_To_The_Knowledge_Of_The_Robber_Flies_From_Vietnam_With_Description_Of_Nine_New_Species_Diptera_Asilidae_

In their study, the authors found and described 9 Asilidae species new to science. One of them: Choerades xuansonensis sp. N. was found in Xuan Son National Park.

This specimen in the photo was observed just outside Xuan Son National Park. So, if it is a Choerades sp., it could very well be Choerades xuansonensis.

Can anyone comment?

Thanks in advance,
David

Hi David, Chris & Wojciech,

On inaturalist there are three photo's of Choerades sp:
https://www.inatu...s/37628409
https://www.inatu.../179665159
https://www.inatu...s/37724123
Difficult to see, but none look like Choerades xuansonensis Tomasovic & Bartolozzi 2018

As to Mactea, there are four described species, the only one with entirely golden haired abdominal terga is Mactea pyrrhothrix Hermann, 1914. A specimen would need to be collected to compare or desscribe the species in the photo.

Kind regards,
Ectemnius
