Abstract
- Ten Opilioacaridae species from the genera Caribeacarus and Neocarus are found in subterranean habitats in Brazil, and several new species are waiting to be described. As part of our studies on cave opilioacarid species, two new species from Peruaçu Caves National Park, Minas Gerais state, are described in the present paper. The two new species present six or more d type setae on the palp, with a stout and rounded lobe: Neocarus chimerasp.nov. with 6 to 9 setae and Neocarus peruassusp.nov. presents 6 or 7 foliate setae (d1). The combination of these characters is a transitional state observed between Neocarus (4 to 9 foliate d type setae on palp, with a stout and rounded lobe) and Caribeacarus (8 to 12 foliate d type setae on palp, with a fine and pointed lobe). The systematic position of the new species is briefly discussed. Additionally, the habitat description and some ecological notes are provided for both new species. [ABSTRACT FROM AUTHOR]
