Etymology.

The specific name comes from a Latin word ‘fascia’, which refers to the silver band on its abdomen; nou n.

Diagnosis.

Males distinguished by the presence of a filiform embolic apophysis extending beyond the conductor tip and a 'Z'-shaped embolus (Figs 28B, D). Exposed portion of embolic apophysis is smaller compared to Zoma didaiyin ( Miller et al. 2009: fig. 10F).

Female distinguished from Zoma didaiyin by the mildly convex posterior margin of the epigyne and the higher position of the spermathecae relative to the copulatory ducts (Figs 29A, B).

Description.

Carapace brownish yellow in males, brown in females. Sternum yellow with dark brown margins. Legs yellow. Abdomen beige in males, dark grey in females with silver pecks forming a transverse belt.

Male pedipalp: Patella with macroseta. Tibia with one trichobothrium. Paracymbium hooked with short, pointed tip (Fig. 28B). Median apophysis lightly sclerotized, similar to Zoma didaiyin ( Miller et al. 2009: fig. 10D). Conductor translucent. Embolic apophysis filiform, with triangular tip (Fig. 28C).

Vulva: Epigyne a flat orange plate with a low median pit. Spermathecae subspherical, juxtaposed. Copulatory ducts follow simple curve (Fig. 29A, B).

Male: Total length 1.52, carapace 0.72 long, 0.60 wide, clypeus 0.14, sternum 0.37 long, 0.31 wide, coxae IV separated by their width. Posterior median eyes separated by less than half their diameter. Macrosetae: Leg I: femur p 1, patella d 1, tibia d 1, p 1, r 1; Leg II: patella d 2, tibia d 3, v 2, r 1; Leg III: patella d 1, tibia d 1; Leg IV: patella d, tibia d 1. Metatarsal trichobothria: Tm I: 0.21; Tm II: 0.20; Tm III: 0.27. Leg measurements: I 2.19 (0.70, 0.25, 0.50, 0.47, 0.27); II 1.99 (0.63, 0.23, 0.44, 0.39, 0.30); III 1.16 (0.31, 0.23, 0.22, 0.23, 0.17); IV 1.45 (0.39, 0.21, 0.31, 0.31, 0.23).

Female: Total length 1.80, carapace 0.88 long, 1.00 wide, clypeus 0.18, sternum 0.50 long, 0.30 wide, coxae IV separated by their width. Posterior median eyes separated by less than half their diameter. Macrosetae as in male. Metatarsal trichobothria: Tm I: 0.30; Tm II: 0.19; Tm III: 0.27. Leg measurements: I 2.11 (0.63, 0.31, 0.47, 0.39, 0.31); II 1.97 (0.63, 0.31, 0.39, 0.39, 0.25); III 1.47 (0.47, 0.23, 0.31, 0.25, 0.21); IV 1.16 (0.31, 0.23, 0.23, 0.23, 0.16).
