Leptogryllus deceptor Perkins, 1910
Oahu deceptor bush cricket
Taxonomy & Nomenclature
Extinct (Dalrymple et al., 2023)
Last record: 1910 or before
IUCN RedList status: Extinct in the Wild
Although listed as Extinct in the Wild by the IUCN (Orthopteroid Specialist Group, 1996) and thus implying that the species still exists in captivity, this seems to be a mistake as no individuals are known to survive in any ex situ collection (K. Zippel cited in Maas, 2011; Dalrymple et al., 2023).
Oahu, Hawaiian Islands, USA
Type locality: Pacific, North-Central Pacific, Hawaii, Hawaiian Is., Oahu, 457 to 610 meters above sea level
Biology & Ecology
The holotype is a female (Nishida, 1979).
Zimmerman (1948) was only aware of 1 specimen, presumably the holotype, and thus it seems as if the species may only be known from a single record.
