News from the depths: A new cave-dwelling flatworm species from the Brazilian savanna

28 enero 2015

Field research in a limestone cave in the Brazilian savanna recorded the first obligate cave-dwelling flatworm of the suborder Continenticola in South America. The species has the characteristic triangular head of the South American freshwater planarians of the suborder, but it is eyeless and unpigmented, as are typical cave-dwelling organisms. The species belongs to the genus Girardia, in which species recognition is difficult. However, the new species shows a unique feature in its reproductive apparatus.
