Taxonomy & Nomenclature

Synonym/s: Nyctimene santacrucis Troughton, 1931:206 [orth. error used by Lee et al., 2017]


Conservation Status


Last record: 1892 or before (collection); 1892 (Martin et al., 2023); 1907 (sighting) (Mickleburgh et al., 1992; Fisher & Blomberg, 2012)

IUCN RedList status: Data Deficient


The holotype was donated to the Australian Museum in July 1892, so must have been collected in that year or prior. The last sighting was apparently on Nendö in 1907 (Mickleburgh et al., 1992). However, there is some doubt about exactly which island in the Santa Cruz group that the holotype came from (Flannery, 1995:235).



Probably Nendö (=Santa Cruz Island), Santa Cruz Group, Solomon Islands






Only known from the holotype, a female.
