Thread subject: Diptera.info :: Mystery...calliphorid? parasiting Hyloscirtus frog

Hello all!

On an amphibian survey on El Oro, Ecuador, a team of herpetologists found a Hyloscirtus frog with serious subdermal myasis, the larvae found are somewhat difficult for identifying, and i submit some pictures of them. We are very interested in what could be the species, because we are trying to evaluate the environmental stress on amphibians on a forest preserve using the parasitic load on them.

If these black plates are really the posterior spiracles than it is not Calliphoridae. It is difficult to judge from the photo's if these are anal pads or posterior spiracles. I don't think this would become some member of a palaearctic family. There is a member of an Australian Chloropidae living under the frogs skin (Batrachomyia) but the known larvae of Chloropidae have a different posterior spiracle. Also Bufolucilia (Calliphoridae) infest toads but Calliphorids do have other posterior spiracles. Would you please check if these black 'pads' do have smaill pores or not.

The third likely family is Sarcophagidae, but I can't tell from these pictures what family the larva is.

The dark areas in the spiracles dissapears with clearing, I hope the cleared images are easier to classify :D

Possibly Hemilucilia sp?
