Three species of dasyatid stingrays in Southeast Asia are presumed to be endemic freshwater species or are known only from freshwater habitats:Himantura krempfi (Chabanaud, 1923), known mainly from specimens obtained at Pnom Penh, Kampuchea, without precise indication of habitat;Himantura signifer new species, described from specimens caught in the Kapuas basin, western Borneo, and tentatively identified as occurring also in the Indragiri River, Sumatra, Perak River, western Malay Peninsula, and Chao Phrya River, Thailand; and an unidentifiedDasyatis orHimantura from the Mekong River in Laos. In addition to these, an unidentifiedHimantura is reported from the Fly River basin; this is the first record of a stingray from fresh water in New Guinea.
