Pholcus gou Yao & Li sp. nov.
Figs 15–16
Type material. Holotype: male, above Kampetlet, below Mountain Oasis Resort (21°11.727′N, 94°02.018′E, elevation 1585 m), South Chin State, Myanmar, 17 May 2014, P. Jäger leg. Paratype: 1 female, same data as holotype.
Etymology. The specific name is from the Chinese pinyin for hook (gōu), in reference to the shape of procursus distally; noun.
Diagnosis. This species resembles P. py u Huber, 2011 (see Huber 2011: 142, figs 505–507, 523–524, 574–579) in having similar male chelicerae (Fig. 16 D), uncus (Fig. 16 C) and female external genitalia (Fig. 16 A) but can be distinguished by the presence of a sclerotized apophysis distally and a membranous dorsal process subdistally on the procursus (arrows in Fig. 15 C) and by the large pore plates on the vulva (Fig. 16 B).
Description. Male (holotype): Total length 4.76 (5.00 with clypeus), carapace 1.08 long, 1.06 wide, opisthosoma 3.68 long, 0.96 wide. Leg I: 38.44 (9.36 + 0.48 + 9.74 + 717.50 + 1.36), leg II: 25.5 (6.84 + 0.46 + 6.47 +10.77 + 0.96), leg III: 14.63 (4.36 + 0.42 + 3.64 + 5.51 + 0.70), leg IV: 21.87 (6.72 + 0.41 + 5.32 + 8.46 + 0.96); tibia I L/d: 97. Distance PME-PME 0.32; diameter PME 0.08; distance PME-ALE 0.04; distance AME- AME 0.03; diameter AME 0.05. Sternum wider than long (0.71/0.65). Habitus as in Figs 16 E–F. Carapace yellowish, with nearly triangular brown marks posteriorly; ocular area brownish, with a median brown band; sternum yellowish. Legs yellowish, patellae, distal parts of femora and tibiae, and proximal parts of metatarsi dark brown, darker rings absent. Opisthosoma pale grey, with dark brown spots dorsally. Ocular area elevated; each eye triad on top of a short, laterally directed eye-stalk (as in P. zhuchuandiani sp. nov., cf. Fig. 31 E). Thoracic furrow absent. Chelicerae as in Fig. 16 D, with a pair of proximo-lateral apophyses; a pair of dark brown distal apophyses with two teeth each. Pedipalps as in Figs 15 A–B; trochanter with a long ventral apophysis; femur with a dorsal apophysis proximally; procursus with a sclerotized apophysis distally and a membranous dorsal process subdistally; bulb without uncus; appendix complex with four apophyses (arrows in Fig. 16 C, one of them only visible in retrolateral view); embolus short, weakly sclerotized. Retrolateral trichobothrium of tibia I at 2.8%; legs with short vertical setae on tibiae, metatarsi and tarsi; without spines and curved setae; tarsus I with approximately 13 distinct pseudosegments.
Female: Similar to male, habitus as in Figs 16 G–H. Total length 4.97 (5.17 with clypeus), carapace 0.97 long, 0.94 wide, opisthosoma 4.00 long, 1.03 wide; tibia I: 6.09; tibia I L/d: 61. Distance PME-PME 0.23; diameter PME 0.07; distance PME-ALE 0.03; distance AME-AME 0.03; diameter AME 0.03. Sternum wider than long (0.67/ 0.56). Carapace with brown V-pattern posteriorly and brown marks marginally. Ocular area yellowish, without eyestalks. External genitalia (Fig. 16 A) with a small indistinct knob. Vulva (Fig. 16 B) with a sclerotized anterior arch and two nearly elliptic pore plates.
Distribution. Myanmar (South Chin State, type locality; Fig. 32).
Natural history. The species was found in secondary forest along stream.
