Abstract
Charinus taboa sp. n. comprises the twenty-second species of the genus described for Brazil. The new species belongs to the eastern Brazilian group, in which all species have sucker-like gonopods. Charinus taboa sp. n. has a marked sexual dimorphism in the pedipalps as do other members of the genus in the country. The description of Charinus taboa sp. n. offers an opportunity to discuss some aspects of ecology, troglomorphism and conservation within the genus. A key to the eastern Brazilian species of Charinus is provided.

Diagnosis:
Charinus taboa differs from other species of the genus by the following combination of characteristics: frontal process with thickened apex; median eyes reduced, with flattened tubercle; lateral eyes not developed and without pigmentation (little pigmentation in smaller individuals); tritosternum with a slightly forked apex; pedipalps sexually dimorphic; femur of the pedipalp with 4-5 dorsal spines (typically 5) and 5-6 ventral spines (typically 5); patella of the pedipalp with 6-7 dorsal spines (typically 6) and 4 ventral spines; distitibia of the leg IV with 16 trichobothria; female gonopod sucker-like, with irregular opening and edges with a small fold; male gonopod with pairs of Pi and LoL1 emerging from each side of the Fi with thin prolongations, and pairs of LoD and LoL2 claw-shaped emerging from the interior of the upper portion of Fi.
Etymology: The specific epithet is treated as a noun in apposition and refers to the name of the cave (Taboa) where most of the specimens were collected.
Distribution: The new species is known from the Taboa and BR 24 caves, state of Minas Gerais, Brazil.
