Hi,
maybe this is not Acricotopus, but I don't know where to place this specimen.

Hi, Andreas,
This species looks like Acricotopus longipalpus Reiss based on yr figures, especially the location of 1st and 2nd laterals of mentum, the median mental teeth and inner teeth of mandible with high variety. some times with 4 median mental teeth, the inner teeth of mandilbe some times are wornout, it give a appearrance with many teeth. The sample look like collecting from Tibet?

… yes, but in Makarchenko 1999 is a Acricotopus longipalpus Reiss 1968 with a palmate S1 (6-10 setae) and the middle teeth are closer together and the RO on antenna is basal, not apical like this one here confused
