Justification: Known only from the Mananjary drainage. Its presence in rivers to the north remains a possibility but needs confirmation. In the adjacent Namorona drainage the species is replaced by Bedotia sp. Ranomafana. Habitat degradation and pressure from exotic predators (Gambusia holbrooki) and competitors (Xiphophorus spp.) have eliminated B. geayi from low altitude (< 100 m a.s.l) habitats, however, it remains abundant in the middle and upper reaches of the Mananjary. Pending major shifts in land use in the basin, this species is assessed as Vulnerable on the basis of its extent of occurrence and area of occupancy being less than 20,000 km² and 2,000 km², respectively, with a continuing decline in distribution due to the above mentioned pressures. |
