Abstract
Present day distribution of Arctocorisa carinata (C. Sahiberg 1819) is composed of several geographically isolated populations. Results of previous investigations on morphological and morphometric characters, structure of male stridulatory signals, and experimental crosses of the populations are summarized: All these characteristics group the populations into ecological and geographic sets, thus expressing both environmental adaptation and probable kinship of the populations. Relationships of the populations were used to reconstruct postglacial distributional history of the species: It is suggested that the present day distribution has resulted simply from direct dispersal of the species to newly available areas during the Late Glacial period, and that later isolation of the populations has been caused by climatic and related changes which have destroyed habitats of the species from wide areas. The possibility that A. carinata would have survived in glacial refuges does not seem probable.
