Etymology. The species epithet is derived from the Latin ‘ parvi ’ and ‘ triangulus ’, referring to the small and triangular atrium in this new species; adjective.

Diagnosis. The new species is similar to N. pseudovietnamensis sp. nov. in having the small and triangular atrium, the large copulatory ducts, the small and anteriorly situated spermathecal heads ( Figs 78A–B, 79B–C), but can be distinguished from the latter by the widely separated and elliptic copulatory ducts, the complex spemathecal stalks which are not entirely covered by copulatory ducts ( Figs 78A–B, 79B–C).

Eye measurements: AME 0.05; ALE 0.13; PME 0.11; PLE 0.13; AME– AME 0; AME–ALE 0; ALE–PLE 0; PME–PME 0.08; PME–PLE 0.04. Clypeus height 0.13. Leg formula: IV, I, II, III; leg measurements: I: 8.60 (2.25, 2.80, 2.20, 1.35); II: 7.35 (1.95, 2.45, 1.75, 1.20); III: 6.60 (1.85, 1.95, 1.80, 1.00); IV: 9.45 (2.45, 3.00, 2.70, 1.30).
