Genus Irura Peckham & Peckham, 1901

Type species.

Irura pulchra Peckham & Peckham, 1901 from Sri Lanka by original designation.

Comments.

The genus Irura Peckham & Peckham, 1901 is placed in the subtribe Simaethina Simon, 1903 together with other 12 genera and is represented by 18 species mainly distributed from East and Southeast Asia ( Maddison 2015; WSC 2022). It is rather poorly understood because the generotype is known from single-sex and lacks key diagnostic drawings. According to the morphological character, the genus is similar to Stertinius Simon, 1890 in having the PME closer to AME than to PLE, three pairs of conspicuous muscle depressions on the dorsum of abdomen ( Logunov 2022), but it differs by the sub-oval carapace and the well-developed (extending exceed the cymbial base) cymbial apophysis mostly possesses a pointed terminus, whereas almost square carapace, less-developed (not extending exceed the cymbial base) cymbial apophysis without pointed terminus in Stertinius (see Metzner 2022).
