Proctophyllodes canora sp. nov. ( Figs 20–24 , 27, 30 )

Holotype male, from Garrulax canorus (Linnaeus) ( Passeriformes : Timaliidae ), Libo (25°19′N, 107°56′E), Guizhou, China, 22 August 2007, coll. Zi-Ying Wang. Paratypes 4 males and 8 females, same data as holotype.

Male. Idiosoma length 257(231–257), width 138(120–138). Prodorsal shield length 80(68–80), width 101(91–101). Distances between scapular setae: se-se 52(50–52); lateral margins entire. Setae ve absent. Setae c 2 in medial margin of humeral shield. Subhumeral setae c3 lanceolate, 16(15–17) in length, 6.7(4.8–6.8) in width. Hysteronotal shield: length 155(145–155), width 91(80–92); anterior margin straight. Interval between prodorsal shield hysteronotal shield: 17(15–17). Supranal concavity opened from the posterior margin, anterior end extending beyond level of setae e2, and to midlevel

© Zoological Systematics, 39(2): 248–258 between e1 and e2. Terminal lamellae ovate, with pennate venation, length of lamellae 29(24–29), width 15(15–18), not overlapping. Epimerites IV-shaped. Paragenital apodemes absent. Genital arch well developed. Aedeagus extending to level of setae g end, not to ps3, 59(59–88) in length. Opisthogastric setae arranged in trapezoidal arrangement. Opisthogastric shield fragmented into four shields, two anterior plates larger and two posterior bearing seta ps3. Anal suckers cylindrical, 13(12–16) in length, 11(10–13) in width, corolla with approximately 20 small teeth. A spine-like projection at the apex of tarsus IV. Distances between hysteronotal setae: c1-c1 57(57–59), c 1-d1 32(25–32), d1-d2 61(61–64), e1-e1 63(62–67), h1-h1 21(21–48), d2- e1 27(27–37), c2-d2 93(88–96), d2- e2 30(28–37), e1-h1 72(71–86), e2-h2 31(15–31), g-g 9.1(7.9–8.8), ps3-ps3 18(18–21), g-ps3 11(9.0–12.0). Tarsus IV 28(24–28) long, with a spine-like projection at the apex, seta d near midlevel of this segment. Genual solenidion σ III situated at posterior segment. Length of genual solenidia: σ1 I 25(22–25), σ III 7(6–8).

Female. Length of idiosoma 344–371, width 148–162. Prodorsal shield: posterior margin straight, 85–91 in length, 111–127 in width. Setae ve absent. Distances between scapular setae se-se 71–76. The arrangement of c1 and c2 as in males. Subhumeral setae c3 lanceolate, 22–27 long, 4.7–6.9 wide. Hysterosoma with a large anterior shield and the lobar region, but the striated area barely discernible. Anterior shield roughly rectangular, with anterior margin almost straight, greatest length 240–253, width at anterior margin 105–121. Interval between prodorsal and hysteronotal shields 9.8–19.0. Setae h1 on striated area. Length of setae h3 94–97. Without supranal concavity. Opisthosomal lobes in small size and lightly attenuate apically, terminal cleft in a form of triangle, 33–37 in length, 24–29 in width. Epimerites IV-shaped, without lateral extensions. Distance between dorsal setae: c1-c1 60(58–65), c1-d1 52(51–52), d1-d2 32(30–32), e1-e2 68(58–68), h1-h1 37(34–40), d2-e1 77(65–77), c2-d2 82(82–93), d2-e2 108(100–107), e1-h1 77(76–78), e2-h2 68(64–69). Genual solenidion σ III situated as in male. Length of genual solenidia: σ1 I 30–36, σ III 9–12.

Diagnosis. The new species, Proctophyllodes canora sp. nov., belongs to the tricetratus species group. Within this group, the new species is similar to P. minlae Atyeo & Braasch, 1966 from Minla cyanouroptera Hodgson, 1838 (Timaliidae) by having small terminal lamellae and an opisthogastric shield which is split into two pairs of sclerites. The new species can be distinguished from the latter as follows: in male, the terminal lamellae is ovate and with pennate venation; there is a spine-like projection only at the apex of tarsus IV but not ambulacra. In males of P. minlae , the terminal lamellae is rectangular and with radiate venation; and apex of each ambulacra has a spine-like projection except tarsus IV.

Etymology. The specific name, canora , is derived from the specific name of the type host.
