Collected at Robinson Crusoe Is. at dusk and night. One specimen previously collected at Robinson Crusoe Is. was misidentified as Gnathophis catalinensis (SIO65-658: 371 mm TL) (Ref. 89357). Also Ref. 27540. The species is reported from Southwest Pacific (Australia, New Zealand) according to Karmovskaya and Paxton (2000), but this reference has to be checked.
