MALE. Total length males 4.30 - 5.40 mm. Holotype: carapace dark brown with white tuft between and behind AME eyes and black protruding setae hooding AM eyes (Fig. 15 a ), area between and behind PME and between AME and ALE covered with short white setae, intermitted with protruding brown setae; in posterior half of thorax centre a pale narrow longitudinal stripe (Fig. 12 a ) instead of a diamond-shaped white area in other known species. Posterior margin of thorax with appressed black setae, opposite front edge of abdomen bearing brushes of dark erect hair in the middle, white on sides as in females (Fig. 12 a , c ), reduced or lost in some specimens. Chelicerae long, divergent (Fig. 12 b ), medially slanting. Maxillae distally widened with angular tip and a toothlike sub-tip. Leg I with dark femur, tibia and metatarsus dark with one or more pale rings; legs II-IV pale with narrow dark rings around the joints and femora with prolateral dark lengthwise stripes, tibia I and II with 2 pairs of ventral spines, metatarsi I and II with one pair at base (Fig. 12 a ). Abdomen gradually tapering, dorsally with wide buff coloured central band (colour in live specimens unknown), covered with very small scales, on either side a wide lateral band covered with white scales (Fig. 12 a ); venter covered with big round to triangular buff to brown scales and flanked by a pale area with some sparce very small iridescent scales (Fig. 12 b ). Pedipalp with base of palpal femur dark, rest light, patella and tibia white, cymbium dorsally dark except base and tip (Fig. 14 b ). Tip of etb extends slightly beyond tip of sperm duct loop (Fig. 14 a , c ). Embolus relatively short (e. g., compared to P. jesudasi, Kanesharatnam and Benjamin 2019 : fig. 18 A).

Measurements. Total length 4.80. Carapace 2.20 long, 1.50 wide, 1.10 high, chelicerae 0.8 long, abdomen 2.50 long, 1.10 wide. Legs: I 4.90 (1.50 long [0.40 wide] – 0.70 – 1.20 – 0.90 – 0.60, leg II 3.80 (1.10 [0.30 wide] – 0.50 – 0.80 – 1.00 – 0.40) leg III 4.00 (1.20 [0.30 wide] – 0.50 – 0.80 – 0.90 – 0.60 leg IV 4.40 (1.40 [0.35 wide)] – 0.50 – 0.90 – 1.10 – 0.50. Palp - 0.7 – 0.3 – 0.25 – 0.6, width cymbium 0.25.

FEMALE. Paratype. Carapace paler than that of male, head pale, lacking white area in eye region, but with bunch of white setae on clypeus. Anterior eyes surrounded with white hair, a white moustache is present below the front eyes (Fig. 13 c ). present. Femur I with a prolateral and retrolateral dark longitudinal stripe, a prolateral one on leg II and III and none on femur IV (Fig. 13 a ). All legs with black rings at base and tip of the patella and tibia. Abdomen pale, dispersed with brownish scales, mostly on the sides (Fig. 13 d ). Venter uniform pale, very small iridescent scales (Fig. 13 b ). Palps uniform pale. Epigyne (Fig. 13) similar to C. lauta and C. volupe , spermathecae considerably larger, touching, “ bird’s neck ” short and thin and lacking a twist; outer margin (ora) of bird’s beak reaching down till 2 / 3 of spermathecae. In dorsal view, upturned fertilization ducts pointing to each other with acute tip behind are visible behind spermathecae (Fig. 13 d ). For hypothetical illustration of copulatory mechanics, see Fig. 16 .

Measurements. Paratype. Total length 4.50. Carapace 1.90 long, 1.30 wide, 1.10 high, abdomen 2.75 long, 1.72 wide. 1.42 high. Legs: I 2.90 (0.90 [0.35 wide] – 0.50 – 0.60 - 0.50 – 0.40) leg II 2.55 (0.80 ([0.25 wide] – 0.35 – 0.55 – 0.45 – 0.40), leg III 3.00 (0.95 – 0.40 – 0.60 – 0.70 – 0.35) leg IV 3.80 (1.15 – 0.50 – 0.75 – 0.90 – 0.50).

Diagnosis

Males of P. scandens differ from most Phintelloides species by the absence of a white tuft on the clypeus in front of the AME in males (Fig. 15 a ). The thorax in males has a narrow white V-shaped strip in the middle instead of a diamond-shaped white area in other species. The female carapace (Fig. 12 c ) has markings similar to the male and unlike the characteristic pattern of P. jesudasi . The male abdomen (Fig. 12 a ), has a wide dark median band on the abdomen between a pair of yellow lateral bands as in P. jesudasi and in P. versicolor . The female abdomen pattern is the reverse of that in males (Fig. 12 c ). The structure of the male and female reproductive organs are generally similar to those of C. lauta and P. jesudasi . The male can be distinguished by differences in the colour of palpal segments, and by the form of the etb, which is longer and more slender than in P. jesudasi and fairly uniform in width, running alongside the tegulum over most of its length (Fig. 14 c ); the embolus has the same length as that in jesudasi, the proximal tegular lobe is smaller. The female wears a narrow bunch of white setae on the clypeus (Fig. 15 b ); epigyne lacks the widening of the bird’s-neck, the atrium is smaller and narrow, the ora (outer rim) is clearly longer; the spermathecae are round and larger than in any other species of the genus, with a diameter equal to the length of the ducts (Fig. 13).

Etymology

From the Latin word scandere, to climb, referring to the fact that all known specimens were collected by fogging tree canopies.

Distribution

Known from two locations in Sabah Province, northern Borneo. In the Kinabalu area, recorded from secondary forests near Sorinsim adjacent to primary forest. At Keningau, in isolated disturbed young secondary forest patches 10 and 20 years old.
