Aegla charon n. sp. is endemic to the “Lago Subterrâneo” cave from the Alto
Ribeira karst region, southeastern Brazil. T e most remarkable morphological
trait observed in the new species was the presence of partially developed pair
of uniramous pleopods 2–5 in adult male specimens, whereas the absence of
these pleonal appendages is the general condition in this sex in Aegla Leach,
1820. Some of the pleopods are even morphologically similar to those typically
observed in adult females in that they may also be two-segmented, only shorter
in size. T e pigmented area of the cornea is slightly reduced, which is probably a troglomorphic adaptation to subterranean habitats. Aegla charon n. sp. is also the only obligate cave-dwelling aeglid known to inhabit lentic subterranean waters. A key to all species from the Alto Ribeira karst area is provided.
