Hello

Coming back to this one, if you have the specimen perhaps you can answer the following questions which should help us to get to the species


Femur 2 with a tuft of bristles and long setulose hairs in the basal ½ of the ventral side

Femur 2 with spines - if yes how many and where

Are pre ac present, how many pairs? this is an important point check also for bristle sockets

Number of av setae on tibia 3

How many p setae on tibia 2, a phot would be useful to check for fine hairs

Number of pd and pv setae on tibia 3

Does tibia 3 anteroventrally on apical 2/3rds and posteroventrally on about middle 1/3rd have conspicuously long setulose hairs

Check that femur 1 has tubercles on ventral surface at apex

Is the posterior katepisternal seta remarkably long

A photo of the basitarsus on leg 2 and the abdomen would also be useful

Thanks
