Allothymoites sculptilis sp. nov. ( Figs 4–6 )

Holotype ♂, China, Yunnan, Xishuangbanna, Menglun , rubber plantation (about 20 years) (21º54.463’N, 101º15.978’E), 21 July 2007, Guo Zheng leg.

Paratypes 2♂, Xishuangbanna, Menglun, Paramichelia baillonii plantation (about 20 years) (21º54.772’N, 101º16.043’E), 18 July 2007, Guo Zheng leg.

Etymology. The specific name derives from the Latin adjective sculptilis and means carved, in reference to the presence of a notch on the surface of median apophysis.

Diagnosis. The new species is similar to A. kumadai , but can be distinguished by the developed, membranous conductor, the notched median apophysis, and the absence of sharp angle on the median apophysis. The latter species lacks a distinct conductor and has a median apophysis with a sharp angle (Yoshida, 2009b).

Male (measurements of holotype). Total length 1.38. Prosoma 0.68 long, 0.51 wide, brown, with black stripes, setae. Sternum 0.40 long, 0.38 wide, grey with setae. Opisthosoma 0.73 long, 0.59 wide, grey, with pale spots, without colulus. Eye measurements: AME 0.08, ALE 0.08, PME 0.07, PLE 0.07, AME-AME 0.08, AME-ALE 0.03, PME-PME 0.03, PME-PLE 0.06. Clypeus height about 1.67 times AME diameter, brown, with 2 tubercles. Chelicerae: brown, with 1 anterior tooth; fangs long, slender. Endites: 0.21 long, 0.09 wide, brown with dark pro-edges. Labium fused with sternum, 0.09 long, 0.13 wide, with 4 setae, brown. Leg measurements: I 2.53 (0.88, 0.21, 0.69, 0.44, 0.31); II 2.20 (0.75, 0.25, 0.56, 0.35, 0.29); III 1.43 (0.46, 0.16, 0.31, 0.25, 0.25); IV 1.60 (0.50, 0.19, 0.38, 0.28, 0.25). Leg I oax yellow, without spot; femur brown, with black stripes; patella-tarsus yellow, with black stripes; femur with 2 rows of spines, patella with 2 spines, tibia with 2 spines, 2 trichobothria, metatarsus with 2 trichobotria, tarsus without spine. Legs II–IV similar to leg I, femur III–IV pale yellow. Pedipalpus ( Figs 4A–B , 5A–C , 6A–D ): tibia yellow, with black spots, 2 trichobothria; cymbium yellow, with large black spot; paracymbium hooded; subtegulum broad; tegulum confined; median apophysis well developed, with notch; embolus short, strongly sclerotized, without basal processes; conductor membranous, with dent; tegular apophysis with notch.

Variation. Male paratypes. Total length 1.00–1.15; prosoma 0.44–0.53 long, 0.44–0.46 wide; sternum 0.28–0.29 long, 0.28–0.29 wide; opisthosoma 0.54–0.63 long, 0.53–0.58 wide.

Female. Unknown.

Distribution. Only known from type locality (Yunnan).
