Both new species were found in caves in Brazil. One was named after the Jequitinhonha river, in whose drainage basin the animals were found. The other species name is Latin and stands for living in a cave.
For the experts: Two new species of troglobiotic Brazilian palpigrades are described: Eukoenenia jequitinhonha sp. n., found in Lapa do Córrego do Vieira cave (Caraí, Minas Gerais) and E. cavatica sp. n., found in Cazanga cave (Arcos, Minas Gerais). The importance of documenting the occurrence of troglobiotic species, even if they are represented by only a single specimen, is discussed.
