(examined).
Synonymy justification
. The male pedipalps of
N. approximata
and
N. tolucana
each present a straight embolus, two-piece tegular median process, and a RTA with a dorsal projection larger than ventral projection. The epigynum of
N. tolucana
is as in
N. approximata
except for the proportional distance between the copulatory openings (slightly closer together in
N. tolucana
). This variation is present throughout the examined material from central
Mexico
where the species is broadly distributed.
Diagnosis
. The males of this species are similar to
N. bosencheve
in having the tegular median process with two projections and to
N. clara
in having a short embolus. They differ from
N. bosencheve
in having the RTA with ventral and dorsal projections of different size (
Figs. 3
d, 4b), and from
N. clara
in having the RTA without a small subprocess on the ventral projection (
Fig. 4
b). The females are similar to
N. cieneguilla
and
N. clara
in having the atrium superficial, but differ from
N. cieneguilla
in having the atrium occupying half the width of epigynal plate (
Fig. 4
c), and from
N. clara
in having the spurs less conspicuous (
Fig. 4
e).
