 Etymology: The specific name is from the Malagasy word for east; a noun in apposition.

 Male: Unknown.   
 Female (Holotype): Total length 8.10. Markings similar to Figure 7A, B. Carapace 3.30 long, 2.50 wide; thoracic fovea length 0.18 that of carapace; clypeus 0.24 high; ocular area 0.45 long, 1.08 wide; ratio of eyes AM/AL/PM/PL, 1.43: 3.00:1.14:1.00, diameter of PM 0.16. Chelicerae 1.40 long, robust, smooth, promargin of fang furrow with six teeth, retromargin with seven teeth. Sternum 1.74 long, 1.40 wide; labium 0.62 long, 0.56 wide; palpal coxa 1.10 long, 0.46 wide. Femur I length 2.00 times carapace length. Palpal femur with three anterobasal thorns. Calamistrum origin at 0.50 from metatarsus base, length 0.35 that of segment. Leg measurements (femur + patella + tibia + metatarsus + tarsus = [total]) I: 6.60 + 1.35 + 6.20 + 6.00 + 2.70 = [22.85]; II: 5.15 + 1.20 + 4.35 + 4.20 + 2.05 = [16.95]; III: 4.15 + 1.05 + 3.30 + 3.40 + 1.80 = [13.70]; IV: 5.90 + 1.15 + 4.65 + 4.65 + 4.50 = [20.85]; palp: 1.55 + 0.55 + 0.80 + (absent) + 1.70 = [4.60]. Epigynum as in Figure 36B; vulva as in Figure 37B, spermathecal base with longitudinal, bilobed chamber, two spermathecal coils close together.   
 Variation (N = 2): Total length 8.10–9.20; carapace length 1.32–1.38 times width, height 0.36–0.40 times width; PER width 2.40–2.98 times OAL; OQP 1.20– 1.21 times OQA; clypeal height 1.50–1.60 times AM diameter; cheliceral length 5.53–5.83 times clypeal height; promargin of fang furrow with 5–6 teeth, retromargin of fang furrow with 6–7 teeth; sternum length 1.24–1.31 times width; femur I length 2.00– 2.13 times carapace length; metatarsus I 1.82–1.95 times carapace length; epigynum as in Figures 33G and 36B, vulva as in Figures 33H, I and 37B.
