Type host. Grandala coelicolor Hodgson, 1843 — grandala. Type locality. Sikkim, India.

Description. Both sexes. Head shape, structure, and chaetotaxy as in genus description and Fig. 177. Median extent of dorsal preantennal suture near ads variable, but suture not medianly continuous. Thoracic and abdominal segments as in genus description and Figs 175–176. Sternal plates and median tergopleurites very pale; tergopleurites progressively darker laterally. Lateral margins of sternal plates hard to see in some specimens.

Male. Abdominal chaetotaxy as in Table 2 and Fig. 175. Basal apodeme (Fig. 178) roughly rectangular, but widened distally. Proximal mesosome broadly quadratic, widening distally. Gonopore (Fig. 179) as subparallel, submedian sclerites, open distally and proximally. Mesosomal lobes with distinct thickening at about mid-length; distal part of lobes rugose or papillate; 2 pmes barely visible just posterior to thickening of each lobe, lateral to gonopore. Parameral heads (Fig. 180) large, bifid, folded into horseshoe-shapes. Parameral blades short, rounded with distinct thickening just distal to short parameral neck; pst1–2 sensilla, submarginal on median margin. Measurements ex Grandala coelicolor (n = 13 except n = 12 for TL, PRW, PTW): TL = 1.87–2.16 (2.05); HL = 0.38–0.41 (0.40); HW = 0.37–0.40 (0.38); PRW = 0.24–0.26 (0.25); PTW = 0.35–0.39 (0.37); AW = 0.38–0.50 (0.46).

Female. Abdominal chaetotaxy as in Table 2 and Fig. 176. Subgenital plate (Fig, 181) triangular, not approaching vulval margin; distal end pointed. Detached cross-piece broad. Vulval margin gently rounded (Fig. 181), with 4–5 short, slender vms on each side, and 6–7 short, thorn-like vss on each side; 2–3 long, slender vos; distal seta median to vss. Measurements ex Grandala coelicolor (n = 8): TL = 2.34–2.70; HL = 0.43–0.46; HW = 0.40–0.45; PRW = 0.26–0.29; PTW = 0.38–0.42; AW = 0.44–0.54.
