Diagnosis

Scape as long as F1 and F2 combined; preoccipital furrow present, with small interocellar pit; OOL 2.58 × lateral ocellus diameter; posterior mesosomal comb present. Male genitalia: harpes taken together pagoda-shaped in ventral and dorsal view; harpe/gvc index 0.27; ventromedial margins of harpes not touching at distoventral margin of gvc, ventromedial margin of harpe convex in basal third, slightly concave in apical two thirds and converging and touching distomedially; ventral margin of harpe straight, dorsal margin convex in basal half and straight in apical half, lateral margin concave.

Etymology

The species is named after the pagoda-shaped harpes of the male genitalia.

Condition of type material

In the holotype, the posterior third of the metasoma is missing, thus the body length measurement is not precise.
