Typhleotris madagascariensis previously was listed as Vulnerable. Improved information since then has resulted in the species being uplisted to Endangered.
Both nominal species of Typhleotris exhibit very restricted ranges and patchy distributions, given their limestone cave habitats. It is likely that more than 2–3 species of Typhleotris inhabit the southwestern region of Madagascar. This has not been a region of focus for ichthyologists and little is known regarding the ranges or population sizes of the two nominal species. For this species, the estimated extent of occurrence (EOO) is < 5,000 km² and area of occupancy (AOO) is < 500 km² and it is most likely found in less than six locations. It is also indicated that the EOO and habitat are declining. On this basis this species is assessed as Endangered. However, if further research finds these caves to hold numerous species with allopatric distributions in the region then the assessment may need to be raised to Critically Endangered as the distribution range for each species will be lower than originally thought. Taxonomic work is required before such an assessment can be made.
