Atractides (Polymegapus) putihi Wiles, 1991 

( Figs. 19 A –DView FIGURE 19 A – D)

Material examined. 0/ 2 /0 (0/ 1 /0 mounted), Kipungit River, Poring Hot Springs, Mt. Kinabalu, Borneo, Malaysia, 6 º 02.776 N, 116 º 41.432 E, 568 m asl., 15 -ix- 2012.

Female. Described by Wiles (1991) and Pešić & Smit (2009). Here we give additional figures and measurements based on a female from Borneo.

Measurements —Idiosoma length/width 483 / 366; coxal field: length 263; Cx-III width 272; Cx-I+II medial length 114, lateral length 181; genital field length/width 116 / 122, genital plate length 58–60, length Ac 1–3: 22 –25, 22–24, 23– 24; egg (n = 1) maximum diameter 110.

Palp: Total length 230, dorsal length/height, dorsal length/height ratio: P1, 23/ 21.5, 1.07; P2, 55/ 32, 1.72; P3, 42/ 27, 1.52; P4, 75/ 21, 2.66; P5, 35/ 12, 2.8; length P- 2 /P- 4 ratio 0.74. Capitulum ventral length 88, chelicera total length 145.

Legs: I-leg- 5 dorsal length 111, ventral length 100, dorsal length/ventral length ratio 1.1, maximum height 39, dorsal length/maximum height 2.8, S- 1 length 52, length/width ratio 8.4, S- 2 length 51, length/width ratio 6.7, distance S- 1-2 3.0, length ratio S- 1 / 2 1.0; I-leg- 6 length 62, central height 11, length/central height ratio 5.7; length I-leg- 5 / 6 ratio 1.8.

Remarks. The single female from Kipungit River matches the general morphology of Atractides putihi Wiles, 1991  . This species was described by Wiles (1991) from Malaysia, based on a single female and later on reported by Pešić & Smit (2009 male and female) from Thailand. According to Wiles (1991) several specimens were collected from Sulawesi. A. putihi  differs from other members of the subgenus Polymegapus  in having I-leg- 5 with ventral margin shorter than dorsal margin ( Fig. 19 DView FIGURE 19 A – D) and probably represent an early derivative member with the typical I- L not yet fully developed.

Distribution. Malaysia ( Wiles 1991), Thailand ( Pešić & Smit 2009). New for Borneo.
