Oodemas laysanensis Fullaway, 1914
Laysan weevil
Taxonomy & Nomenclature
Synonym/s: Oedemasylus laysanensis Fullaway, 1914 (used in error by World Conservation Monitoring Centre, 1996; Chris Lyal, pers. comm. March 2014)
Conservation Status
Missing
Last record: 1964 (source); June 1990 (Neal Evenhuis, pers. comm. April 2014 to Alexander Lang)
IUCN RedList status: Extinct
According to Neal Evenhuis (pers. comm. April 2014 to Alexander Lang), this species was last definitely collected on Nihoa in 1990, although more recent specimens may have been collected as not all specimens have been identified from collecting expeditions. Therefore this species is unlikely to be extinct, even though it is currently considered to be by (World Conservation Monitoring Centre, 1996; Lyal, 2014).
This species was previously evaluated as extinct under the erroneous name "Oedemasylus laysanensis" (World Conservation Monitoring Centre, 1996), and was set to be corrected in the next update of assessments (Chris Lyal, pers. comm. March 2014). The slated assessment appeared in due course, retaining the species as extinct (Lyal, 2014).
Distribution
Laysan, Midway, Nihoa and Necker Island, Hawaiian Islands, USA (Perkins, 1926)
Contra Perkins (1926), this species may not have occurred on Necker or Nihoa.
