Leptogryllus deceptor Perkins, 1910

Oahu deceptor bush cricket

 

 

Taxonomy & Nomenclature

 

 

Conservation Status

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).

 

Distribution

Oahu, Hawaiian Islands, USA

Type locality: Pacific, North-Central Pacific, Hawaii, Hawaiian Is., Oahu, 457 to 610 meters above sea level

 

Biology & Ecology

 

 

Hypodigm

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.
