Taxonomy & Nomenclature



Conservation Status

Last record: 1 July 1937

IUCN RedList status: Extinct


"In the 1960's, Dave Rentz was revising the Dectininae crickets when he came across a specimen of an apparently new species of the Neduba genus that had lain unidentified in a museums collections since the late 1930's. Its large size, differently shaped pronotum, and other characteristics were unique. Despite several large scale field excursions to California's Antioch Dunes (which have been largely blown and hauled away) it has never again been recorded. Rentz pronounced it gone and named it 'extincta'."
