Etymology.

The specific name is a Latin adjective referring to the species’ similarity to N. javana (Simon, 1897), a combination of the preposition sub (near) and the epithet of that species.

Diagnosis.

Females of N. subjavana sp. nov. are similar to those of N. javana ( Hayashi 1996: 66, figs 11-13) by the contiguous copulatory openings and the general shape of the vulva but can be distinguished from the latter by the strongly convoluted copulatory ducts that loop twice (Fig. 14B-D View Figure 14 ) (vs. moderately convoluted, loop once).

Description.

Female (holotype) (Fig. 14F-G View Figure 14 ): Total length 7.16; carapace 2.86 long, 1.96 wide; opisthosoma 4.30 long, 1.18 wide. Carapace uniformly green-white, lighter in cephalic region; radial grooves indistinct, fovea grey and inconspicuous. Eyes: AER nearly straight, PER wider than AER and slightly procurved in dorsal view. AME dark, other eyes light; with black rings. Eye sizes and interdistances: AME 0.09, ALE 0.11, PME 0.12, PLE 0.10, AME-AME 0.09, AME-ALE 0.11, PME-PME 0.32, PME-PLE 0.12, MOQL 0.34, MOQA 0.30, MOQP 0.55. Chelicerae protruding and coloured as carapace, with red wine coloured fangs, with three promarginal and two retromarginal teeth. Labium and endites white. Sternum white. Legs light green, without distinct markings. Leg measurements: I 9.23 (2.63, 4.00, 1.85, 0.78), II (-, -, 2.78, 0.79), III 6.12 (1.99, 2.09, 1.60, 0.44), IV (2.95, -, -, -). Abdomen (Fig. 14F, G View Figure 14 ): dorsum yellowish white with a pair of longitudinal muscle depressions, 1/3 of opisthosoma length; venter white, spinnerets light green.

Epigyne (Fig. 14A-E View Figure 14 ): Plate translucent greenish, slightly wider than long, through which part of spermathecae and copulatory ducts can be seen indistinctly, posterior margin bluish, not rebordered. Copulatory openings distinct, large, contiguous, at posterior portion of the plate. Copulatory ducts strongly entwined, loop twice before connecting to spermathecae. Sperm ~ 1.5 × longer than wide. Bursae globular, separated by ~ 1.6 diameters, translucent, with smooth surface. Fertilisation ducts small, <1/3 spermathecae length, located dorsolaterally on spermathecae.
