Bathippus rectus   , new species

( Figs. 4 View Fig A-D)

Material examined. – Holotype – male ( ZRC.ARA.52), Bukit Timah Nat. Res., Singapore, coll. D. Li, 24 Aug.1999.  

Paratype – 1 male ( ZRC.ARA.53), Bukit Timah Nat. Res., Singapore, coll. D. H. Murphy, 8 Jun.1967   .

Diagnosis. – The arrangement of cheliceral teeth of the new species is similar to that of Bathippus shelfordii Peckham & Peckham, 1907   ( Peckham & Peckham, 1907: 620; Zabka, 1988: 431, f. 22-28), but differs from the latter in the structure of palpal organ; the palpal organ of the new species resembles that of Bathippus molossus ( Thorell, 1881)   ( Plexippus molossus Thorell, 1881: 553   , 708; Bathippus molossus   - Prószynski théfrom, 1984: 8), but differs the latter in embolus relatively longer, coiled in more than one circle and tibial apophysis not hook-like.

Description. – Males. Total length 6.75 (paratype)-8.45. Length of holotype 8.45: cephalothorax 3.42 long, 2.79 wide; abdomen 5.09 long, 2.03 wide. Carapace ( Fig. 4A View Fig ) dark brown, the PME and PLE surrounded by black circle. Eye sizes: AME 0.87, ALE 0.49, PME 0.09, PLE 0.46. Anterior eye row 2.48 wide, posterior row 2.25 wide, eye area 1.62 long. Chelicera ( Fig. 4B View Fig ) long, orange yellow, with 3 promarginal teeth and 1 retromarginal tooth. Endite and labium orange yellow, sternum yellow. Legs: femora I, II and patellae I, II dark red, other segments orange yellow. Femur I dorsally and patella I dorsally and ventrally with dense scopulae. Tibiae I, II and metatarsi I, II each with 4 pairs of ventral spines. Leg measurements: I 13.28 (3.87+5.22+ 3.06+1.13); II 10.36 (3.20+3.69+2.34+1.13); I I I 1 5. 0 4 (5. 0 9 + 4. 9 1 + 4. 1 4 + 0. 9 0); I V 1 0. 0 9 (2.93+3.15+3.20+0.81). Leg formula: 3124. Dorsum of abdomen grayish brown (yellow in paratype), centrally with 2 pairs of small brown spots; venter grayish brown, with 4 rows of light yellow, longitudinal markings. Embolus of palpal organ ( Figs. 4C, D View Fig ) slender, coiled into more than one circle, its basal part swollen as a bulb; tibial apophysis finger-like, not curved.

Etymology. – The specific name refers to the straight apophysis of palpal tibia.
