Figs. 1–8

Type material. Male holotype (PJ 1739), with label: Pseudopoda , Vietnam: Sa­Pa Province, Fan­Si­Pan [summit: 22° 19' N; 103° 46' E], tropical cloud forest, 2000 m, without date, D.A. Krivolutsky leg., (Swedish Museum of Natural History, Stockholm). Fan Si Pan, Vietnam

Diagnosis. ɗɗ Embolus short, distally divided into a hook (part containing sperm duct) and an additional stout apex ( Fig. 4 ). Ventral part of retrolateral apophysis pointed (ventral view; Fig. 2 ).

Description. Male holotype. Prosoma length 3.4, prosoma width 3.1, anterior width of prosoma 1.6, prosoma height 1.2, opisthosoma length 3.4, opisthosoma width 2.0. Eyes: AME 0.15, ALE 0.29, PME 0.22, PLE 0.29, AME­AME 0.09, AME­ALE 0.05, PME­ PME 0.21, PME­PLE 0.28, AME­PME 0.27, ALE­PLE 0.24, clypeus height at AME 0.28, clypeus height at ALE 0.21.

Leg formula: 2143. Spination: Palp: 131,101,2111,2110, legs: femur I­III 323, IV 331, patella I­III 101, IV 0 0 1, tibia I­II 2226, III­IV 2126, metatarsus I­II 2024, III 3024, IV 3036. Measurements of palp and legs: Palp 5.3 (1.7, 0.9, 1.1, ­, 1.6), I 17.7 (4.5, 1.7, 5.1, 4.5, 1.9), II 19.2 (5.2, 1.8, 5.5, 4.8, 1.9), III 14.8 (4.2, 1.4, 4.1, 3.8, 1.3), IV 16.5 (4.6, 1.4, 4.4, 4.5, 1.6).

Embolus arising in a 9­o’clock­position, conductor in a 12­o’clock­position on the tegulum. Sperm duct undulated, running along the margin of the tegulum. Retrolateral apophysis arising medially to distally on the tibia. Cymbium with two prolateral spines, one dorsal and one retrolateral spine ( Figs. 1–3 ).

Color (from preserved specimens in ethanol): Pale yellowish­brown with distinct pattern. Dorsal shield of prosoma with dark fovea and radial bands, these fragmented into single spots ( Fig. 5–6 ). Two bristles in front of fovea ( Fig. 6 ). Posterior part of dorsal shield with dark margin. Chelicerae with only three slightly marked longitudinal rows of patches and bristles. Legs with small spots and spine patches on femora and tibiae. Median spine patch of femur largest. Additional patch prolaterally at base of tibia. Sternum, labium and gnathocoxae without pattern. Opisthosoma with posterior half darker. Muscle sigillae darkly marked, with a dark transversal bar behind. Lateral sides of opisthosoma with irregular patches ( Fig. 7 ). Ventral opisthosoma with four single dark spots in its anterior half, these spots form a trapezium. Trapezoid patch in front of the spinnerets ( Fig. 8 ). Anterior spinnerets dorsally dark.

Female: unknown.

Distribution. Only known from the type­locality.

Etymology. The specific name refers to the divided tip of the embolus (Latin: fissus from findere means divided); adjective.
