This species is endemic to southwestern coastal Madagascar and occurs in the vicinity of Andalambezo. It has a restricted range and a patchy distribution, given it only occurs in subterranean habitats and interconnected sites such as caves, sinkholes and wells. For this species, the estimated extent of occurrence (EOO) is approximately 100 km². It is in a single location threatened by increasing tourist visitation and collection of guano. On this basis this species is assessed as Critically Endangered.

Geographic Range [top]

Range Description:This blind and pigment-free obligate cave-dwelling species is endemic to Madagascar. It is restricted to subterranean habitats in coastal regions to the south of Morombe in the vicinity of Andalambezo, southwestern Madagascar (Sparks and Chakrabarty 2012). Typhleotris pauliani is known from the Andranomaly Cave, the Andranomahiha Cave, the Safora Cave, the Anona Cave, the Andakatomivola Cave and near Tulear (Toliara) (Sparks and Chakrabarty 2012). It has also been collected from caves inland and just south of Andavadoaka, extending its range to the north (Sparks and Chakrabarty 2012).

Use and Trade: There is no use or trade information for this species.

Threats [top]

Major Threat(s): Typhleotris pauliani has a very restricted range and a patchy distribution. It occurs in caves and sinkhole habitats that are fragile and rather ephemeral systems. Threats include recreational activities at some locations (caving, intrusion into habitat and disturbance by tourists). In addition, people are now starting to collect guano from the caves and may therefore disturb the habitat.

Conservation Actions [top]

Conservation Actions: No conservation actions are known for this species. Some of these caves are tourist sites and receive some protection from exploitation. Part of the cave system is within the Mikea and complexe Mangoky Ihotry protected areas
