Abstract

The genus Peirates Serville is revised. A total of 32 species are recognized. Its species are assigned to the P. quadrinotatus, P. singularis and P. lepturoides species groups. The P. quadrinotatus species group includes P. argenteopilosus Schouteden and P. quadrinotatus Fabricius; the P. singularis species group comprises its sole species P. singularis StÅl, and the P. lepturoides species group is formed by P. atromaculatus (StÅl) (= P. buruanus Miller, P. consobrinus Miller, P. excelsus Miller, P. immaculatus Miller, P. sordidus Miller, syn. n.), P. monodi Villiers, P. mundulus StÅl, P. nanus Miller, P. niger Signoret, P. nitidicollis Reuter, P. ochripennis Jeannel, P. perinetensis Villiers, P. strepitans Rambur, P. stridulus (Fabricius), P. tellini Schouteden, P. turpis Walker, P. aurigans Distant, P balteatus Germar, P. castaneipennis Reuter, P. cinctiventris Horváth, P. collarti Schouteden, P. confusus Schouteden (= P. amieti Villiers, syn. n.), P. crudelis sp. n., P. dimidiatus Walker (= P. areatus Miller, syn. n.), P. diola Lindberg, P. hybridus (Scopoli), P. lepturoides (Wolff) (= P. mimulus Miller, P. musculus Miller, P. sparsus Miller, syn. n.), P. macilentus Miller, P. marginiventris Distant, P. maurus StÅl, P. monodi Villiers, P. mundulus StÅl, P. nanus Miller, P. nigerrimus sp. n., P. nitidicollis Reuter, P. ochripennis Jeannel, P. perinetensis Villiers, P strepitans Rambur, P. stridulus (Fabricius), P. tellini Schouteden, and P. turpis Walker. Besides, P. sepulchralis Distant and P. sin Linnavuori are transferred to Brachysandalus StÅl, and P. barbarus Miller, P. bicolor Distant, P bicoloripes Breddin, P. flavipes (Walker), P. montivagus Distant, P. pallens Miller, and P. semifasciatus to Lestomerus Amyot & Serville, and P. umbrosus StÅl to Microsandalus StÅl. P. concinnus Walker cannot be assigned to any existing genus. P. cyaneonitens Breddin was not studied, and P. parvulus (Signoret), P. punctum (Fabricius), P. vittatus Reuter are considered as nomina dubia. Species are described, illustrated, and their geographical distribution is mapped. A key for separating all the species is given. A phylogenetic analysis of the species is presented. In the cladogram, the P. quadrinotatus, P. singularis and P. lepturoides species groups are monophyletic and a sister group relationship exists between the P. quadrinotatus group and the combined P. singularis + P. lepturoides groups. The geographical distribution of the species shows an African-Indopacific generalized track with an Indian Ocean baseline. The genus Peirates is hypothesized to have a tropical Gondwanan origin, with subsequent spread into the Palearctic region.
