Taxonomic notes.

Some specimens lack the ultimate pair of legs, a trait used for species-level identification. Other specimens are different from all described species and are likely to be novel, requiring further examination.

Distribution.

Most specimens recorded herein are from limestone caves of Goiás, Mato Grosso, Mato Grosso do Sul, Bahia, and Minas Gerais states. However, some occurrences were reported for iron ore, sandstone, and granitic caves of Pará, Bahia, and Santa Catarina, respectively. Several new occurrences (e.g., at Chapada Diamantina, Bahia) were noted in this study, important for understanding the distribution of cave centipedes.

Habitat.

Cave (unconsolidated substrate).

Conservation.

Iron ore and granitic caves from Pará and Santa Catarina are under threat from large iron-mining projects and urban expansion, respectively.
