Etymology: The species name is taken from the Latin adjective apiculatus (“small-pointed”) and refers to the apiculate ventral process of paracymbium. Diagnosis: The new species is similar to Nesticella mogera (Yaginuma, 1972) in having a hook-shaped ventral process on the paracymbium and similar vulva structure, but can be distinguished by the terminal apophysis developed, pocket-shaped, with many granular processes in N. apiculata , but reduced in N. mogera and by the epigynal scape short in N. apiculata , but long and trapezoidal in N. mogera ( Figs 1–4 , 17–18 ).

Vulva as long as wide; copulatory ducts extending from copulatory openings to spermathecae, with two coils; spermathecae papillary, situated anteriorly and laterally ( Figs 1 D, 2B–C, 4C–D).
