Phoroncidia floripara sp. nov. ( Figs 47–50 )

Holotype ♂, China, Yunnan, Xishuangbanna, Menglun Nature Reserve , secondary tropical seasonal moist forest (21º54.607'N, 101º17.005'E), 28 July 2007, Guo Zheng leg.

Paratypes: 1♂, 1♀, Menglun, Anogeissus acuminata plantation (about 20 years) (21º53.993'N, 101º16.810'E), 19 August 2007, Guo Zheng leg.

Etymology. The specific name derives from the Latin adjective floriparus and means bearing flowers, in reference to the opisthosoma with many apophyses, seems to blooming flower in dorsal view.

Diagnosis. The new species is similar to P. pilula , but can be distinguished by a columned apophysis originating from the opisthosoma; conductor membranous; tegular apophysis with 2 apophyses.

Male (measurements of holotype). Total length 2.25. Prosoma 1.33 long, 0.68 wide, high, brown, anterior part extruded. Sternum 0.43 long, 0.43 wide, brown, with setae. Opisthosoma 2.30 long, 1.48 wide, sclerotized, white, with many brown dents, apophyses; columned apophysis originates from center of opisthosoma, without colulus. Eye measurements: AME 0.08, ALE 0.07, PME 0.08, PLE 0.07, AME-AME 0.11, AME-ALE 0.03, PME-PME 0.07, PME-PLE 0.06. Clypeus height about 6.16 times AME diameter, brown, with tiny apophysis under AME. Chelicerae: brown, without tooth; fangs long. Endites: 0.23 long, 0.09 wide, brown, distal pale, with dark pro-edges. Labium fused with sternum, 0.10 long, 0.21 wide, with 4 setae, brown. Leg measurements: I 1.98 (0.67, 0.28, 0.40, 0.25, 0.38); II 1.66 (0.61, 0.19, 0.33, 0.25, 0.28); III 1.72 (0.56, 0.25, 0.33, 0.25, 0.33); IV 2.16 (0.71, 0.30, 0.48, 0.31, 0.36). Leg I coxa brown, without spot; femur, patella brown; tibia pale, with brown ring; metatarsus pale, with brown ring; tarsus pale; femur without spine; patella with 3 short spines; tibia with 3 spines, 3 trichobothria; metatarsus with 1 trichobothrium; tarsus without spine. Legs II–IV similar to leg I, tarsus pale with brown ring. Pedipalpus ( Figs 47A–B , 48A–C , 50A–D ): tibia yellow, with 1 trichobothrium; cymbium yellow, without spot; paracymbium hooked, from distal part of cymbium; subtegulum broad; tegulum large; median apophysis smooth, without protrusion; embolus long, distal from tegular apophysis; conductor membranous; tegular apophysis with 2 acute apophyses.

Variation. Male paratype. Total length 2.20; prosoma 1.25 long, 0.88 wide; sternum 0.44 long, 044 wide; opisthosoma 2.23 long, 1.60 wide.

Female (measurements of paratype). Total length 3.20. Prosoma 1.25 long, 0.95 wide, flat, brown, anterior part extruded. Sternum 0.55 long, 0.55 wide, brown, with setae. Opisthosoma 3.00 long, 2.10 wide, yellow, with brown dents, many apophyses, columned apophysis from center of opisthosoma. Clypeus height about 1.23 times AME diameter, brown, with apophysis under AME. Legs brown or pale brown, similar to male. Epigynum ( Figs 47C–D , 49A–B ): epigynum flat, without handle; copulatory openings small, narrow; spermathecae spherical, with pleats; copulatory ducts long, curved, from bottom of spermathecae, opening to anterior margin of atrium; fertilization ducts short, curved, from bottom of spermathecae.

Distribution. Only known from type locality (Yunnan).
