''Eresus cinnaberinus'' and ''Eresus niger'' are names formerly used for a group of spiders in the genus ''Eresus'' now divided into three species, ''E. kollari'', ''E. sandaliatus'' and ''E. moravicus''. The three species differ in size, colour pattern, shape of prosoma and copulatory organs, and habitat, with no morphologically intermediate forms. As eastern and western ''E. kollari'' are genetically different, with the eastern form likely a hybrid between "pure" ''E. kollari'' and ''E. moravicus'', it is possible that later revisions will partition it into additional species. Both ''Eresus cinnaberinus'' and ''Eresus niger'' are now regarded as ''nomina dubia''.〔 ==Distributions== * ''E. kollari'' has the widest distribution of the three species, occurring from Spain and Portugal to Novosibirsk in Russia. * ''E. moravicus'' occurs in the Pannonian region, the Balkan Peninsula and parts of the Austrian Alps. * ''E. sandaliatus'' occurs in northern Europe (Denmark, southern Sweden, southern England, Schleswig-Holstein in Germany) and western central Europe (the Czech Republic, the Danube region in Bavaria, the Austrian Alps, northern France). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Eresus cinnaberinus」の詳細全文を読む スポンサード リンク
