Sphingius penicillus View in CoL sp. n. ( figs 847-852 View Figs 847 - 852 , map 41 View 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.

Description. — MALE. Total length 3.85 mm. Carapace length 1.85 mm, width 1.35 mm, height 0.65 mm. head width 0.85 mm, eye group width 0.50 mm; abdomen 1.90 mm long, collar 0.15 mm, 1.10 mm wide. Leg lengths: leg I 5.00 mm (1.50-1.60-1.00-0.90), leg II 4.30 mm (1.20-1.50-0.85-0.75), leg III 3.80 mm (1.00-1.25-0.85-0.70), leg IV 5.80 mm (1.50-1.85-1.45-1.00), palp 0.60-0.30-0.25-apophysis 0.20-0.60 mm. Carapace, mouthparts, sternum and abdomen bright orange-brown, legs orange. Carapace ( fig. 847 View Figs 847 - 852 ) with short thoracic groove from which radiate rows of pits, seta-bearing granules seem smaller than in S. gothicus ; margin as in gothicus . Eyes: d AME half of d ALE, their d apart; PER recurved, d PME 1/2 to 2/3 of d PLE, PME 1-2 d apart, a little less from laterals, and lacking black rings. Chilum obtuse irangular. Leg spination: femora I-III with 1-0d, femur IV 1-1 d, tibia III with 1-1v or l-0v and 0-1 pl, tibia IV with 2-2v and 1-1rl; metatarsus III with 1pv, metatarsus IV 2 -0v or 1-0v. Tarsal claws on anterior legs with 7-8 short teeth, posterior legs 2-3 minute teeth near the base. Scuta as in gothicus , collar short and grooved. Palp figs 848-849 View Figs 847 - 852 , a stout blunt tibial apophysis adjacent to which a black brush. Median apophysis relatively larger than in gothicus , embolus relatively longer and more curved.

FEMALE (1180 m, 14.ii.1987). Total length 4.00 mm. Carapace length 1.75 mm, width 1.40 mm, height 0.40 mm, head width 0.90 mm, eye group width 0.45 mm; abdomen 2.25 mm long, 1.50 mm wide, epigyne 0.30 mm wide, 0.45 mm long. Leg lengths: leg I 5.15 mm (1.50-1.95-0.95-0.75), leg II 4.45 mm (1.25-1.60-0.85-0.75), leg III 3.70 mm (1.00- 1.20-0.85-0.65), leg IV 6.00 mm (1.60-2.00-1.50-0.90), palp 0.60-0.30- 0.30-0.60 mm. Carapace and mouthparts paler than in male, colour of legs similar to that in males. Carapace surface granulated, pits absent. Leg spination: femora as in male, tibia III 1-2v, 0-1pl, tibia IV 2-2v+2ap, 0-1 pl, 0-1 rl, metatarsus III 2 -0v, metatarsus IV 2-1 v. Spinnerets fig. 852 View Figs 847 - 852 . Vulva fig. 851 View Figs 847 - 852 , anterior depression of epigyne ( fig. 850 View Figs 847 - 852 ) elongate, partly traversed by loops of insemination ducts; openings lateral, spermathecae smaller than in gothicus .
