Phycosoma corrugum View in CoL sp. nov. ( Figs 51–54 View Fig View Fig View Fig View Fig )

Holotype ♂, China, Yunnan, Xishuangbanna, Menglun Nature Reserve , secondary tropical montane evergreen broad-leaved forest (21º54.809'N, 101º12.173'E), 4 August 2007, Guo Zheng leg. GoogleMaps

Paratypes 2♀, same data as holotype GoogleMaps .

Etymology. The specific name derives from the Latin adjective corrugus and means crumpled, in reference to the conductor with many little wrinkles.

Diagnosis. The new species is very similar to P. mustelinum , but can be distinguished by shape of the duct connecting themedian apophysis with the embolus in ventral view; copulatory ducts stronger, copulatory openings similar to inverted “U”.

Male (measurements of holotype). Total length 2.50. Prosoma 1.10 long, 0.88 wide, high, columned, yellow, with dark striae, dorsal grooves in middle. Sternum 0.60 long, 0.60 wide, grey. Opisthosoma 1.38 long, 1.10 wide, grey, with pale spots, large white spots, colulus represented by 2 setae. Eye measurements: AME 0.15, ALE 0.08, PME 0.11, PLE 0.09, AME-AME 0.09, AME-ALE 0.04, PME-PME 0.08, PME-PLE 0.09. Clypeus height about 3.33 times AME diameter, brown. Chelicerae: yellow, with dark spots, without tooth; fangs long and slender. Endites: 0.25 long, 0.13 wide, yellow with dark spots and brown pro-edges. Labium fused with sternum, 0.06 long, 0.19 wide, with 4 setae, yellow. Leg measurements: I 3.06 (1.00, 0.38, 0.65, 0.63, 0.40); II 2.76 (0.88, 0.33, 0.63, 0.54, 0.38); III 2.59 (0.81, 0.31, 0.59, 0.53, 0.35); IV 2.91 (0.88, 0.25, 0.75, 0.63, 0.40). Leg I pale yellow, femur, patella and tibia with black spots; with many spines,

© Zoological Systematics, 39 (1): 1–135 patella with 1 spine; tibia with 1–2 spines. Legs II–IV similar to leg I, femur IV, patella and tibia IV with black rings. Pedipalpus ( Figs 51A–B View Fig , 52A–B View Fig , 54A–D View Fig ): tibia with 2 trichobothria; cymbium yellow, without spot; paracymbium hooded; subtegulum broad; tegulum conjoined with median apophysis and embolus; median apophysis smooth, without protrusion; embolus long, partlycovered by conductor, with small protuberances, long basal protrusion; conductor curved, wrinkled after expansion.

Female (measurements of paratypes). Total length 2.60–3.10. Prosoma 1.00–1.01 long, 0.88–0.95 wide, high, yellow, with black striae, without groove. Sternum 0.55–0.60 long, 0.58–0.60 wide, grey. Opisthosoma 1.80–2.25 long, 1.20–1.70 wide, grey, with small pale spots, large pale stripes. Legs yellow, similar to male. Epigynum ( Figs 51C–D View Fig , 53A–B View Fig ): epigynum flat, with handle; copulatory openings similar to inverted “U”; one large pair, one small pair of spermathecae, spherical; copulatory ducts strong, curved, from large spermathecae, opening to anterior margin of atrium; fertilization ducts short, curved, from small pair of spermathecae.

Distribution. Only known from type locality (Yunnan).
