The following specimens were found in 2003-2005 in China on the Tibetan Plateau (see map). Further details see Opens external link in new window Plank (2010)

  • premandible: 2 (or 1 with an incision)
  • seta S1: 7
  • mandible: 3.5-1-0-1 (inner-apical-outer-surface) +/- large surface plate
  • mentum: middle 2, lateral 7 teeth (behind the 1st lateral is a small accessory tooth), beard present submental setation below 3.5st lateral teeth 4th instar (slightly worn mentum)

This species is similar to that one in Zelentsov 1989 but this 4th stage has a worn mentum.

  • premandible 1 or 2 +1 (apical slightly incised +basal)
  • seta S1 1.8
  • mentum: no accessory tooth next to 1st lateral, middle worn, 7 lateral teeth, submental setation below 3.5 lateral tooth, strong beared
  • mandible 3-1-0-0 (inner-apical-outer-surface)
  • 3rd instar?
  • quite strong postoccipital margin
  • premandible: 2+1 (apical+basal);
  • seta S1: 2 long;
  • mentum: 1 median tooth, 6 lateral, submental setation (extremely) laterad;
  • mandible: 3.5/4-1-0-0 (inner-apical-outer-surface), outer margin slightly engraved
  • postoccipital margin: brown
  • antenna: blade ratio=1

Solved: former named Cricotopus-Orthocladius indet 1 it is Cricotopus shilovae Zelentsov 1989.

  • premandible 1+1 (apical+large basal);
  • seta S1 1;
  • mentum: dark brown-black, 1 middle tooth, 6 lateral teeth, submental setation below 5th lateral tooth,
  • mandible 3.5-1-0-0 strongly engraved at outer margin;
  • antenna: RO-ratio (RO/ant-1st) ~0.22, blade ratio=1 i.e. as long as remainig antennal segments
  • postoccipital margin darkbrown-black
  • premandible: 2+2 (apical+basal)
  • seta S1: ?
  • mandible: 4-1-0-0 (inner-apical-outer-surface)
  • mentum: 1 middle, 5 lateral teeth
  • submental setation below 4th lateral teeth
  • premandible 5
  • mentum 1 tooth paler than outer 5 teeth, dark plate behind mentum;
  • antenna: 5 segments, pedicells ~ 2x 3-5th ant.segment, no spur; antennal pedestal: ~1.5x L:W;
  • mandible 3-1-3-2;
  • postoccipital margin dark brown, - plate well develloped trapezoid;
  • gula brown;

former named T. lugens indet 1

  • premandible: 4+1 lateral spine, 
  • mandible: 3-1-2-2 (inner-apical-outer-surface),
  • mentum: lateral 5 teeth
  • 3rd instar
  • antenna 5 segments with small laterborn organs? on pedicells: ~1.5x 3-5ant., antennal pedestal ~1xwidth, no spur
  • head brown
