Diagnostic description: 

Species concept: Morphological Species Concept

Diagnosis: Antennae with 20 antennal articles, the 4 basal antennal articles sparsely hirsute. Second maxillary claw with two accessory spurs. Forcipular coxosternite with 4 + 4 teeth of equal or almost equal size. Tergites from T3 or T4 to T20 with two longitudinal paramedian sutures. Tergites from T4 or T5 to T21 marginated. Sternites from S2 to S19 or S20 with longitudinal paramedian sulci. S21 usually with a longitudinal median sulcus. L1 with 2 tarsal spurs, LL2-19 with 1 spur, L20 with or without spur. Coxopleura relatively short, exceeding S21 by its length at most. Dorsal border of the coxopleura almost semicircular when seen from the side. Coxopleura lateral with 1-2 spines, dorsal with 2-3 spines, apical with 2 spines situated in proximity. Ultimate leg prefemora ectal ventral with 3 (2), mesal ventral with 2 (3), and dorsal usually with 4 prefemoral spinous processes in two rows and 1 distomesal prefemoral spinous process.
