Diagnosis (Karyotypically determined material leg. P. Michailova.)
Exuviae 9.6-13.1mm long (m=10.7mm, n=11).
Cephalothorax: Frontal apotome rounded, not apically truncate, except when the specimen has the apotome squashed into itself. Cephalic tubercles short, less than 100µm high, conical, their bulbous bases meeting medially. Praefrons at most (rarely) with sparse vague granulation, normally smooth apart from the usual creases. Thoracic horn much branched.

EpR II-VI 1.0 : 1.1-1.43 : 1.14-1.64 : 1.76-2.57 : 2.95-4.43 (m=1.0 : 1.22 : 1.4 : 2.25 : 3.76, n=10); length epaulette VI 1.41-1.94x length epaulette V (m=1.71, n=10). Comb of segment VIII of 2-10 teeth (m=5.3, n=10). Lateral taeniae of segments V-VIII: 4,4(5),4,5.
Anal segment: Fringe of anal lobe with 115-178 taeniae (m=150.5, n=10).
