Figures 9-10
Type material — Holotype ♂, dissected and slide mounted ( NBC), Bhutan, MG3 Bipgang Chhu , 27.15729°N, 90.66721°E, 596 m asl, 25 Oct. 2021 GoogleMaps . Paratypes: 4♀, same site and data as the holotype, 1♀ dissected and slide mounted ( NBC).
Diagnosis — Integument finely striated, muscle insertions unsclerotized; mediocaudal margin Cx-I+II deeply indented; Vgl-1 separate from Vgl-2; strong sexual dimorphism (in male P-2 with pointed distoventral projection, P-4 shortened, P-2/P-4 ratio 0.94), anterior margin of the male genital plate with a V-shaped indentation.
Description — General features – Integument striated, muscle insertions unsclerotized; mediocaudal margin Cx-I+II deeply indented ( Figures 9A, 10A), caudal apodemes of Cx-II strongly protruding and forming an acute angle. Excretory pore smooth; Vgl-1 not fused to Vgl-2. Palp with a strong sexual dimorphism, P-4 sword seta stout, nearer to distoventral setae. I-L-5 setae S-1 and S-2 nearer to each other, bluntly pointed, S-1 longer than S-2; I-L-6 stout, proximally thickened, slightly curved ( Figures 9D, 10C).
Male – Anterior and posterior margin of genital plate deeply indented, anterior indentation V-shaped, P-2 ventral margin with a strongly developed pointed distal extension, P-3 slightly concave, P-4 shortened, ventral margin slightly protruding at level of ventral setae ( Figure 9C).
Female – P-2 ventral margin convex distally, P-3/4 straight, P-4 slender than in male ( Figure 10B).
