Last record: March 1967 (Perez, 1973) or 5 June 1968 (Wiles, 1987:154) (collection); 1968 (Bonaccorso et al., 2020); 1974 (Wiles, 1987; Fisher & Blomberg, 2012; Lee et al., 2017); 1979 (Flannery, 1995:293 (citing Wiles, 1987)) or late 1970's (Bonaccorso et al., 2020) (possible sighting)

IUCN RedList status: Extinct


Two specimens, both males (one adult, one age unknown) were collected by W. F. Coultas on 10 August, 1931. These are the only known specimens collected prior to the species' description. A third specimen (a female) was shot and killed by hunters (an accompanying large juvenile managed to escape) either in March 1967 (Perez, 1973) or on 5 June 1968 (Wiles, 1987:154). An unconfirmed report from 1974 exists (Wiles, 1987).
