A new species of Ochyrocera (Araneae: Ochyroceratidae) from caves in the state of Minas Gerais, Brazil, with notes on O. ibitipoca

摘要

Ochyrocera brumadinho n. sp. is described from Brumadinho, state of Minas Gerais, Brazil. This species has morphological affinities with males of O. ibitipoca Baptista, Gonzalez & Tourinho, 2008, in having a cymbial apophysis of the palp enlarged subdistally, and this feature may be a putative synapomorphy that groups these species. It was collected inside caves in the Iron Quadrangle region and compared to Ochyrocera ibitipoca, which also inhabits caves in another region of the same state. Althoughboth species were found in this type of habitat, neither present troglomorphic features.
