Diagnosis.
Females of this species are recognised by the dark dorsum of the abdomen with two V-shaped pairs of pale spots (Fig. 1 A, B View Figure 1 ), by the epigyne with a long, narrow, tapered scape (Fig. 2 A – D, H View Figure 2 ) and by the duct conformation of the vulva (Fig. 2 E – G View Figure 2 ).
Etymology.
The specific name, arborivaga means ‘ active in trees’, refers to the ecology of the species, which has been found in litter but also in trees.

Carapace 1.70 long, 1.14 wide, 0.78 high. Eye sizes and interdistances: AME: 0.10; ALE: 0.08; AME – AME: 0.03; AME – ALE: 0.05; PME: 0.09: PLE: 0.12; PME – PME: 0.12; PME – PLE: 0.13. MOQ: frontal width 0.23, posterior width 0.30, length 0.30. Clypeus 0.36 high. Chilum: small triangle 0.12 wide, 0.10 high. Sternum shield-shaped, 0.85 long, 0.78 wide. All femora with one short, dorsal spine in proximal half.
Legs: measurements in Table 1 View Table 1 .
Epigyne (Fig. 2 A – H View Figure 2 ): Scape (Sc) long, narrow, with widest part in the middle, distally tapered and rounded; copulatory ducts in transparency vague, longitudinal; copulatory ducts in posterior part, mainly transverse, intricately wound, in dense, wide spirals in anterior part.
Male. Unknown.
Variation.
Females (n = 2). TL 4.19–4.47, CL 1.56–1.70. White patches on abdominal dorsum may be less strongly inclined and sometimes anastomosing.
