): extent of occurrence (EOO) <100 km2 (B1) and area of occupancy (AOO) <10 km2 (B2) with one known location (a), and continuing decline of quality of habitat (b). We estimate that in the two subpopulations currently known, fewer than 50 mature individuals occur. These conditions identify the conservation status of the new species as globally Critically Endangered CR B1ab(iii) + B2ab(iii) As a result,
