摘要

The spider genus Taira is diagnosed The female of the type species, T. flavidorsalis (Yaginuma, 1964), from Japan, is illustrated, and a second species, T lunaris new species, from Guizhou, China, is described and illustrated. The genus Taira was established by Lehtinen (1967) to include only one species from Japan: Taira flavidorsalts (Yaginuma, 1964), The new species, T. lunar is, described in this paper is similar to T. flavidorsalis in the female genitalia by having broad epigynal teeth and broad, rounded spermathecae. The phylogenetic position of the genus Taira has not been established. The inclusion of Taira and Tamgrinia in the same tribe, Tairini, by Lehtinen (1967), was questioned by Wang (2000). The genus Taira resembles genera related toAmaurobius, at least by: the striped small hood (Griswold, 1993: 23) of the trichobothria, the undivided chilum, the presence of an "amaurobiid PLS spigot", and the presence of paracribellar spigots on both posterior lateral spinnerets and posterior median spinnerets, while the genus Tamgrinia differs from Taira by having smooth small trichobothrial hoods, a divided chilum, the absence of an "amaurobiid PLS spigot", and the absence of 'paracribellar spigots.
