Contribution to the knowledge of the longicorn beetles of the Caucasus. 8. Genus <i>Purpuricenus </i>Dejean, 1821 (Coleoptera: Cerambycidae)
A review of the Caucasian species of the genus <i>Purpuricenus </i>Dejean, 1821 is given. The detailed bibliography, synonymy, all Caucasian localities (with the maps) known for the author, brief accounts of biology and ecology are indicated for each species. The extensive studied by author collection material is presented. A new and omitted in recently published Catalogue [Catalogue, 2010] synonymy are discussed: <i>P</i>. <i>caucasicus caucasicus </i>T. Pic, 1902 = <i>P</i>. <i>budensis productus </i>Adlbauer, 1992, syn. n., <i>P</i>. <i>wachanrui </i>Levrat, 1858 = <i>P</i>. <i>bilunatus </i>Schaufuss, 1871. The correct type locality of <i>P</i>. <i>caucasicus </i>(Helenendorf, nowadays Geygel, in Azerbaijan) in substitution wrongly indicated (Helenendorf = Helendorf = Elenovka, Armenia, it is so!) by some modern researchers [Sabbadini, Pesarini, 1992; Danilevsky, 2007] (in connection with their confusion in the toponyms) is established. The important morphological features of certain species are given. Some features of distribution on the Caucasus of <i>P</i>. <i>budensis </i>are discussed. It is shown, that almost all its localities are concentrated in east part of this region, and localities on the West Caucasus are very scanty and partly rather doubtful. New data on the habitats of <i>P</i>. <i>caucasicus </i>at the Black Sea coast of Krasnodar region (Russia) are presented. Color photos of all species and their most important forms are given.
