DIAGNOSIS. The female of
Takeoa nishimurai
differs from that of all known species of
Zoropsis
, the only other East Palaearctic genus of
Zoropsidae
, by short scape (
Sc
) not reaching epigastral furrow (
vs
. long scape, reaching epigastral furrow) and by converging receptacles (
Re
) with almost touching heads (
RH
) (diverging or parallel receptacles with widely separated heads) (cf.
Figs 8–10
vs
.
Marusik & Kovblyuk, 2004
: figs 5–6). The male of
T. nishimurai
can be distinguished from that of
Zoropsis
by wide retrolateral tibial apophysis with blunt tip (
vs
. narrow, sharply pointed retrolateral tibial apophysis), triangular retrolateral marginal bump of cymbium (
vs
. elliptical) and by triangular bulging proximal part of tegulum (
vs
. circular; cf.
Bosselaers, 2002
: fig. 1A–B and Griswold & Ubick, 2001: figs 2, 5). Additionally, the male of
T. nishimurai
differs from that of
T. huangshan
Tang, Xu et Zhu, 2004
by non-bifurcated distal part of embolus (
vs
. bifurcated; cf.
Bosselaers, 2002
: fig. 1A and
Tang
et al
., 2004
: fig. 4). The female of
T. huangshan
is unknown.
