Natural history collections help resurrecting Glomeris herzogowinensis Verhoeff, 1898 and further clarify the nomenclature of two Onychoglomeris subspecies of Attems (Diplopoda, Glomerida, Glomeridae)

Abstract

Based on the study of freshly-collected material and old museum specimens, we have solved a decades-old riddle surrounding the name Onychoglomeris herzogowinensis (Verhoeff, 1898). The southern Dinaric coastal species Glomeris herzogowinensis Verhoeff, 1898 is revived, while Onychoglomeris herzogowinensis australis Attems, 1935 and O. h. media Attems, 1935, are treated here as full species after returning the specific name to Glomeris Latreille, 1902, O. australis Attems, 1935, stat. nov. and O. media Attems, 1935, stat. nov. Besides the designation of lectotypes, we provide comprehensive illustrations, diagnoses, detailed remarks and a distribution map for all three species. In addition, DNA barcoding provided COI sequences for Glomeris herzogowinensis and Onychoglomeris australisstat. nov., along with the first barcoding data of one additional species of Onychoglomeris Verhoeff, 1906, O. ferraniensis Verhoeff, 1909 and two Glomeris species, the Balkan G. balcanica Verhoeff, 1906 and the trans-Adriatic G. pulchra Koch, 1847. The significance of historical specimens from natural history museums is briefly discussed.
