Diagnosis — Coxae with sexual dimorphism (in male coxal field merged to an unique plate, including Vgl-3; in female coxal plates separate); ventral margin of P-2 nearly straight, P-3 with one seta each on medial and lateral surface extending beyond ventral margin of segment; in male S-1/-2 close to each other (separation 9-10 μm). Description — General features — Integument dorsally striated, muscle insertions unsclerotized. Coxae with sexual dimorphism. Excretory pore smooth; Vgl-1 separate from Vgl-2. Palp with weak sexual dimorphism, ventral margin of P-2 nearly straight, forming a right distal angle, not protruding, P-3 with one seta each on medial and lateral surface, P-4 sword seta between ventral setae. I-L-5: S-1 longish and blunt, S-2 pointed and thicker than S-1, I-L-6 curved, basally thickened. Male: Coxae with extended secondary sclerotization, forming a coxal shield, including Vgl-3 ( Figure 8A ); genital plate with extended convex margin of secondary sclerotization, posterior margin indented, acetabula in an obtuse triangle ( Figure 8E ); P-4 thickened, slightly elevated near insertion of proximoventral seta ( Figures 8 C-D). Female. Coxal plates separate ( Figure 9A ); acetabula in a weakly curved line ( Figure 9B ); P-4 more slender ( Figures 9 C-D).
