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.enCave-dwellingGrupo BambuíMyriapodaNeotropicsPainsTroglomorphicArtigo
