Diagnosis
Goniocotes caoi sp. nov. is most similar to Goniocotes chrysocephalus , with which it shares the following morphological characters: preantennal head with inner curved line separating median less sclerotized region and lateral and anterior more sclerotized region ( Figs 1–3 View Fig View Fig View Figs 3–5 ); proepimera fused medianly ( Figs 1–2 View Fig View Fig ); smns absent ( Figs 1–2 View Fig View Fig ); psps present on male tergopleurites II–IV ( Fig. 1 View Fig ); tps absent on male tergopleurites III–VII ( Fig. 1 View Fig ); male tergopleurites IV–VII with narrowed inner part that reaches at least halfway between edge of abdomen and midline on each side ( Fig. 1 View Fig ).
Goniocotes caoi sp. nov. can be separated from G. chrysocephalus by the following combination of characters: occipital bulge at site of mts5 less pronounced in G. caoi ( Fig. 3 View Figs 3–5 ) than in G. chrysocephalus ; tps absent on male tergopleurite II in G. caoi ( Fig. 1 View Fig ), but present in G. chrysocephalus ; ss absent on male tergopleurites VI–VII in G. caoi ( Fig. 1 View Fig ), but present in G. chrysocephalus ; ps absent on male abdominal segment III in G. caoi ( Fig. 1 View Fig ), but present in G. chrysocephalus ; female vulval margin with small patch of vms microsetae near lateral corners in G. chrysocephalus , but without such patch in G. caoi ( Fig. 5 View Figs 3–5 ).
Etymology
Goniocotes caoi sp. nov. is named after the classical Chinese author Cao Xueqin, who wrote Hongluo Meng (Dream of the Red Chamber), considered one of the Four Great Classics of Chinese literature. This is in reference to this new species being Chinese, and living amongst the mainly red body feathers of its host.

Description
Frons rounded, in some specimens appearing slightly pointed ( Fig. 3 View Figs 3–5 ). Marginal carina broad, with clear attendant canals of preantennal setae. Internal line separating median, less densely sclerotized area from lateral and anterior more densely sclerotized area; in at least some females this line is also visible in the post-antennal head ( Fig. 2 View Fig ). Preantennal nodi elongated, rounded in male, more square-shaped in female. Male os microsetae, may be slightly thorn-like. Lateral temporal margins rounded, divergent posteriorly. Occipital bulge present, not very prominent; mts situated apically. Occipital nodi prominent.
Thoracic and abdominal segments and chaetotaxy as in Figs 1–2 View Fig View Fig . Rhombic sclerite not fused to pronotum. Pronotum with rounded to slightly extended postero-lateral corners. Proepimera fused medianly. Postero-lateral corner of pteronotum not extended laterally; posterior margin gently rounded; smns absent. Male tergopleurites much reduced on more posterior segments; tergopleurite VIII with no visible median extension; lateral tergopleurite IX+X small, slender, not reaching median sclerite. Lateral accessory sternal plates absent. Male abdominal chaetotaxy: ss present on tergopleurites II–V; tps and aps absent; psps present on tergopleurites II–VII; ps present on abdominal segments IV–VIII. Female abdominal chaetotaxy: ss present on tergopleurites II–VIII; tps and aps absent; psps present on tergopleurites V–VI; ps present on abdominal segments III–VIII.
Male genitalia as in Fig. 4 View Figs 3–5 ; solenoid, with no clear distal margin; pst visible as sensilla and parameres widening at site of pst.
Female genitalia as in Fig. 5 View Figs 3–5 ; subgenital plate absent, but section of ventral surface nearest vulval margin marginally more densely sclerotized than other parts (symbolized by a curved line in Fig. 5 View Figs 3–5 ). Vulval margin somewhat flattened medianly, with 8–10 short, slender vms and 3–5 longer, thorn-like vss on each side; 2–4 short, slender vos on each side, the distalmost of which is near vss. Subvulval plates present, roughly oval.
Measurements as in Table 1.
