Conservation Status


Last record: 1920 (Martin et al., 2023); 1936 (Sody, 1940)

IUCN RedList status: Data Deficient


Sometimes listed as last recorded in 1920 (e.g. Martin et al., 2023). This seems to be an error of unknown origins since the original description (Sody, 1940) clearly states that the holotype was collected in 1936.



Enggano island (=Pulau Enggano), West Sumatra, Indonesia

Only known from the holotype (Aplin & Lunde, 2008).
