- premandible: 2(+x)? (apical+basal),
- mandible: 3-1-2-1 plate (inner-apical-outer-surface),
- mentum: 1 middle (?crenate) lateral 5 teeth,
- 4th? instar,
- pop: postoccipital plate well developed (triangular),
- pom: postoccipital margin brown,
- head pale yellow,
- antennal pedestal: ~2x width, with well developed spur on pedestal (about as long as wide)
Head (4th? instar):
difficult to say: either a Micropsectra due to premandible (its seems to be bifid) or Tanytarsus due to mandibular teeth ...
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
