Morellia aenescens maybe?

I am confident this is a Morellia species, and suggest it is a good match for Morellia aenescens, female. It certainly looks good comparing with one on Dipterists Info. Though if you asked me to substantiate it, I would struggle.
It does look like the hind femur is bent - should it be the tibia instead? In fact all the femurs look bent!

Re: Morellia aenescens maybe?

I now think I can justify it being Morellia aenescens, on the basis that it would appear to be the only one in the genus that has a single posterior bristle on the front tibia, and a bent hind tibia. General appearance matches very well to this species too.

Re: Morellia aenescens maybe?

Agreed. This is a female - the bend in the hind tibia is much more obvious in the male.
