Expanding the range of the troglobitic millipede Pseudonannolene ambuatinga Iniesta & Ferreira, 2013: insights into its distribution and conservation status (Spirostreptida, Pseudonannolenidae)

Abstract

Pseudonannolene Silvestri, 1895 (Spirostreptida, Pseudonannolenidae) is one of the most common genera of millipedes in Brazilian caves. To date, only three troglobitic species are known in a list of 56 species described for the genus. In this study, we report new records of the cave-dwelling species Pseudonannolene ambuatinga Iniesta & Ferreira, 2013 in Minas Gerais state. These records extend its distribution by approximately 600 km2, making it the most widely distributed cave-dwelling millipede in the country. We also provide a new assessment of its conservation status based on the records and threats to its populations.
