Brueelia impressifrons Ansari, 1956a; Price et al. 2003: 155.

Type host. Trochalopteron affine affine (Blyth, 1843) — black-faced laughingthrush. Type locality. Nepal.

Other host. Trochalopteron affine bethelae (Rand & Fleming, 1956) — black-faced laughingthrush.

Description. Both sexes. Head shape, structure, and chaetotaxy as in genus description and Fig. 163. Frons flat to shallowly concave; hyaline margin irregular. Dorsal anterior suture irregular, does not reach dsms. Gular plate broadly triangular. Thoracic and abdominal segments as in genus description and Figs 161–162. Metepisterna with intensely pigmented nodi sublaterally. Sternal plates translucent or with very pale brown pigmentation. Tergopleurites translucent medianly, but with strong brown pigmentation laterally, surrounding spiracle openings. Re-entrant heads almost square-shaped, but with concave anterior margins.

Male. Abdominal chaetotaxy as in Table 2 and Fig. 161. Basal apodeme (Fig. 164) constricted at mid-length, wider distally. Proximal mesosome slender, widening proximally. Gonopore open proximally and distally (Fig. 165), as lateral ventral angular sclerites; anterior ends of sclerites extended laterally. Mesosomal lobes angular, wider proximally, fused distally; 2 pmes sensilla near lateral margins of lobes. Parameral heads (Fig. 166) narrow, bifid. Parameral blades triangular; all examined males with distorted parameres, and these may be longer than depicted in Fig. 121. Measurements ex Trochalopteron affine bethelae (n = 1): TL = 1.72; HL = 0.42; HW = 0.32; PRW = 0.23; PTW = 0.28; AW = 0.39.

Female. Abdominal chaetotaxy as in Table 2 and Fig. 162. Subgenital plate (Fig. 167) roughly pentagonal, reaching vulval margin where it flares into medianly displaced cross-piece. Vulval margin (Fig. 167) gently rounded to flat medianly, with 4–6 short, slender vms on each side, and 6–9 stout, spool- to thorn-like vss on each side; 3–5 long, slender vos; distal vos median to vss. Measurements ex Trochalopteron affine affine (n = 6): TL = 1.72–2.18; HL = 0.43–0.49; HW = 0.33–0.38; PRW = 0.23–0.26; PTW = 0.29–0.33; AW = 0.36–0.45. Ex T. a. bethelae (n = 2): TL = 1.98–2.09; HL = 0.45–0.47; HW = 0.35; PRW = 0.25–0.26; PTW = 0.30–0.31; AW = 0.43– 0.45.

Type material. Ex Trochalopteron affine affine [as Garrulax affinis affinis]: Holotype ♂, Nepal, Dec. 1935, R. Meinertzhagen, 4853 (NHML). Paratypes: 6♀: same data as holotype [one of these is the allotype, but it is not clear which one it is].
