Other host. Ithaginis cruentus clarkei Rothschild, 1920—blood pheasant.

Description.

Both sexes. Head broad, frons broadly rounded ( Fig. 15 ). Marginal carina slender. Dorsal preantennal suture not extending far lateral to ads. Head chaetotaxy as in Fig. 15 . Thoracic and abdominal plates and chaetotaxy as in Figs 15–16 . Reticulation limited to lateral ends of tergopleurites II–VII in male and II–XI in female and subgenital plates of both sexes.

Male. Antennae as in Fig. 29 ; tooth-like projection of scape moderate; no rugose area of flagellomere I. Accessory sternal plates absent. Stylus short, of roughly equal width throughout ( Fig. 84 ). Basal apodeme slender ( Fig. 57 ). Mesosome large, distal margin rounded, median section concave; antero-lateral hooks slender ( Fig. 59 ). Gonopore short, very narrow distally. Ventral sclerite broad, shaped as in Fig, 59; one submedian microseta and one sublateral pore visible on each side on posterior margin; in addition one pore visible postero-lateral to ventral sclerite on each side. Parameres short, slender, with stout, irregular heads ( Fig. 58 ); pst1 much proximal to pst2. Measurements as in Table 1 .

Female. Tergopleurites IX+X and XI separate ( Fig. 16 ). Subgenital plate diffuse, shaped as in Fig. 75 , medianly divided; reticulation of subgenital plate with net-like structures near lateral ends ( Fig. 75 ). Vulval margin deeply and narrowly concave, with 16–21 setae marginally on each side; median setae more widely spaced than lateral setae. Posterior lobes of abdomen slender and extended. Subvulval plates slender in distal half, broader in proximal half; proximal ends reach anterior to vulval margin. Measurements as in Table 1 .
