( figs 847-852 , map 41 ) Type locality .— Thailand , Prov. Chiang Mai , Doi Chiang Dao . Type material.— 1 ♂ holotype ( MHNG ) from the type locality, 510 m , pitfall traps, 25.x.- 23.xi. 1990 ; paratypes : 10 ♂ ♂, 1 ♀, same data ( MHNG ), 1 ♂ ( MHNG ), 22.ix-25. x.1990 , 5 ♂ ♂ ( CD ), 23.xi-22- xii.1990 , 1 ♀ ( CD ), pitfall trap, 22.xii. 1990 - 15.i. 1991 , id. , 1 ♀ ( MHNG ), 15.i.-23.i.1991 , all P. Schwendinger . Other material .— None. Diagnosis. — This species is characterised by the brush of black setae on the male palpal tibia and the M-shaped duct apparent in the anterior depression of the epigyne. Similar to S. gothicus , distinct by the lighter colour, in males close to orange-brown, in females pale orange, and the unicolour orange legs. The surface of the carapace is pitted as in S. gothicus in males, females have a smooth carapace. S. scrobiculatus can be distinguished from S. penicillus by the shorter male tibial apophysis which is of uniform width over most of the length and absence of tibial brush. Figs 847-852.
