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 View Figs 6–12 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.
