Type host. Grammatoptila striata sikkimensis (Ticehurst, 1924) — striated laughingthrush (sikkimensis). Type locality. Chungtang , Sikkim, India.

Description. Both sexes. Head shape, structure, and chaetotaxy as in genus description and Fig. 155 . Head shape sexually dimorphic ( Figs 153–154 ). dsms very short, situated in or lateral to dorsal preantennal suture. Many antennal setae very long ( Figs 155–156 ). Frons translucent, but does not appear to be hyaline. Thoracic and abdominal segments as in genus description and Figs 153–154 . Abdominal shape highly sexually dimorphic. Pleural heads rounded, slanted. Tergopleurites and sternal plates with pale brown pigmentation, pleurites moderately brown.

Male. Head short ( Fig. 155 ). Antennae as in Fig. 155 . Abdominal chaetotaxy as in Table 2 and Fig. 153 . Basal apodeme ( Fig. 157 ) rounded rectangular. Proximal mesosome elongated, overlapping with basal apodeme, slenderly trapezoidal, widening slightly in anterior end. Gonopore ( Fig. 158 ) as convex submedian sclerites, narrowly ope distally. Mesosomal lobes bipartite, with ventral horn-like section in anterior ends ( Fig. 158 ), and dorsal lobe-like section distally; dorsal section of lobes with extensive fringe on distal margin; 2–3 ames sensilla visible ventral to proximal mesosome ( Fig. 158 ). Parameral heads ( Fig. 159 ) narrow, bifid. Parameral blades triangular; pst1–2 sensilla, submarginal near distal tip. Measurements ex Grammatoptila striata sikkimensis (n = 1): TL = 1.51; HL = 0.43; HW = 0.39; PRW = 0.26; PTW = 0.36; AW = 0.55.

Female. Head long ( Fig. 154 ). Antennae as in Fig. 156 . Abdominal chaetotaxy as in Table 2 and Fig. 154 . Subgenital plate broadly triangular, lateral margins convex ( Fig. 160 ), flaring into cross-piece distally, but not reaching vulval margin medianly. Vulval margin ( Fig. 160 ) concave medianly, with 7–10 short, slender vms on each side, and 9–10 short, thorn-like vss on each side; lateral vss longer, more spool-like; 5–7 long, slender vos; distal 2 vos median to vss. Measurements ex Grammatoptila striata sikkimensis (n = 4): TL = 1.86–2.00; HL = 0.47–0.51; HW = 0.43–0.47; PRW = 0.26–0.29; PTW = 0.35–0.38; AW = 0.55–0.58.
