Hi,
difficult to say: either a Micropsectra due to premandible (its seems to be bifid) or Tanytarsus due to mandibular teeth ... confused

It would be Tanytarus gracilentus (Holmgren) based on the plate-like surface teeth on the mandible. I had recorded in my ph.D.

the T.gracilentus in Brooks et.al. 2007 has a distinct plate behind the mentum and no spur on antennal pedestal as well ... that's why I placed it separately

This is most probably a Micropsectra. The antennal pedestal spur and bifid premandible is typical of this genus
