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
).
