Gular very slightly darkened on posterior third, and frontoclypeus pale.
Mentum of type II, with somewhat rounded teeth; c1 tooth relatively narrow with very short diverging sides, then rounded; c2 teeth moderately separated (type IIA-III).
Ventromental plates about 211 µm long and 3.7 times longer than deep; separated by about 0.22 of mentum width with about 39-40 striae, VMR 0.32-0.35.
Pecten epipharyngis with 13 short, thick teeth (type B).
Antenna with A1 3.7 times longer than wide and 0.4 of VHL; RO about 0.40-0.42 up from base; AR 1.73; A2/A1 about 0.22. Segment lengths (µm): 121 : 36 : 11 : 15 : 8.
Distance between S4 setae just greater than distance between antennal bases, and about 0.87 of Frontoclypeus width at that point.
Mandible with short heel, length about 230 µm, 16 furrows on outer surface near the base, 3rd inner tooth partly separated and colored (type IIB), Pecten mandibularis with 13-14 taeniae, 3 spines on margin; MTR about 0.40.
Cytology: 4 pairs of relatively short chromosomes with the thummi arm combination AB, CD, EF, G. Arm G short and usually unpaired with a subterminal nucleolus. No nucleolus in longer chromosomes.
Arm E often unpaired. Puff with distal dark bands just near the 4 characteristic bands of arm B.
