A revision of the Afrotropical species of the genus Tibellus Simon (Araneae: Philodromidae)

Abstract

The Afrotropical species of the genus Tibellus Simon, 1875, are revised. Of the 10 previously recognised species of long-bodied grss spiders from this region, eight are redescribed and figured. Two species, T. punctifasciatus Strand, 1906, and T. robustus Simon, 1886, are considered nomina dubia. Five new species, T. cobusi, T. gerhardi, T. nimbaensis, T. somaliensis and T. sunetae, are described and three previously recognised subspecies of T. vossioni Simon, 1884, namely T. v. armatus Lessert, 1928, T. v. flavipes Caporiacco, 1941, and T. v. minor Lessert, 1919, are given species status. The genus Tibellinus Simon, 1910, is a junior synonym of Tibellus. Tibellinus australis is transferred to the genus Tibellus. The males of T. armatus stat. nov. and T. hollidayi Lawrence, 1952, are described for the first time. A key to 17 recognised species is given. Distributional data are provided for all species.
