(Figs. 4, 5)
Description. MALE (holotype). Body 190 long (185–200 in 3 paratypes) and 125 wide (120–145). Idiosomal shields devoid of ornamentation, soft idiosomal cuticle striated, without scales or tubercles. Dorsum. Distance between propodonotal and hysteronotal shields about 22. Propodonotal shield 47 long (42–51) and about 68 wide (51–70), posterolateral extensions encompassing bases of setae se and si. Posterior margin of propodonotal shield not straight, corrugated. Setae se about 32 long. Hysteronotal shield transversely separated. Its anterior part 57 long (52–57) and 83 wide (75–83), its lobar part paired, 73 long (63–74) and 29 wide (26–33). Setae d2 absent. Humeral shields well developed, with bent extensions. Opisthosomal lobes about 70 long, separated from each other. Terminal cleft longer than its greatest width. Venter. Coxal apodeme IIIa weakly developed, not entire shields, coxal fields III opened. Genital arch as an inverted V with tips strongly curved laterally. Aedeagus 22 long (15–22). Adanal shields 29 long (26–29) and about 4 wide, subparallel to each other. Coxal apodeme IVb about 18 long (15–18) and 2 wide (2–3). Diameter of adanal suckers 9 (7– 9). Cupules ih situated at posterior of adanal suckers. Legs. Legs III thinner than legs IV, about 92 long. Femora III with 1 dorsal and 1 ventral weakly developed retrorse processes. Other processes on legs III and IV absent. Solenidion ω1 I absent. Setae ba I, II absent. Tarsi IV curved medially and produced apically. Lengths of setae: cp 115 (95–110), c3 28 (22–26), h2 160 (150–160), h3 21 (21–32), ps1 18 (17–19), ps2 26 (24–28), d II 69 (64–72), d III 80 (66–80), ω3 about 15, ω1 II about 22, φ I 28 (30–33), φ II 45 (44–49), φ III about 3, φ IV about 22, σ1 I 14 (12–15), and σ II about 3.
FEMALE (5 paratypes). Body 200–220 long and 155–165 wide. Idiosomal shields without ornamentation, soft idiosomal cuticle striated, without scales or tubercles. Dorsum. Distance between propodonotal and hysteronotal shields about 35. Propodonotal shield 42–50 long and 46–58 wide, postero-1ateral extensions encompassing bases of setae se and si. Posterior margin of propodonotal shield not straight. Setae se about 30 long. Hysteronotal shield 80–91 long and 62–70 wide. Posterior margin curved inwards at medium. Setae d2 absent. Humeral shields well developed, with bent extensions. Venter. Coxal fields III closed. Adanal shields well developed, separated from each other, encompassing setae ps1, ps2, ps3, h2 and h3. Legs. Legs III and IV subequal, about 96 long. Femora III and IV each with 1 dorsal and 1 ventral moderately developed retrorse processes. Inner side of basal tarsi III and IV with small projection each. Other processes on legs III and IV absent. Solenidion ω1 I absent. Setae ba I, II absent. Lengths of setae: cp 95–105, c3 24–28, h2 150–170, h3 40–48, ps2 21–26, d II 49–60, d III 60–79, ω3 14–19, ω1 II 16–21, φ I about 35, φ II about 40, φ III and φ IV about 2, σ1 I about 13, and σ II about 2.
Type material. Holotype male, 3 male and 5 female paratypes ex Garrulax poecilorhynchus berthemyi (David and Oustalet) (Passeriformes: Timaliidae), CHINA: Guizhou, Guiyang, 26°56'04'' N, 106°44'17'' E, 5 January 2013, coll. X.-H. Su.
Etymology. The specific epithet derives from the specific name of the host.
Differential diagnosis. The new species is closest to Passeroptes turdoides Fain and Bochkov, 2003 from Turdoides jardineii (Passeriformes: Timaliidae) (Fain & Bochkov 2003). In both sexes of these two species, setae d2 are absent; in males legs IV are slightly thicker than legs III; and in females, setae se do not extend to the anterior margin of the hysteronotal shield, coxal fields III are closed, and femora III and IV each bear one dorsal and one ventral retrorse process. The new species differs from P. turdoides by the following features. In both sexes of P. poecilorhynchus sp. nov., setae ba- I, II are absent; setae se are 4–5 times longer than si; in males, the hysteronotal shield is transversely separated and legs IV lack processes; in females, the ventral retrorse processes on femora III and IV are moderately developed. In both sexes of P. turdoides, setae ba- I, II are present; in males, the hysteronotal shield is not transversely separated, setae se are only 1–2 times longer than si, and tibia IV bears a strong sub-basal ventral process directed apically; in females, the ventral retrorse processes on femora III and IV are well developed.
