The Recently Extinct Plants and Animals Database

Pachnodus velutinus Pfeiffer, 1868

Velutine pachnodus (proposed)



Taxonomy & Nomenclature

Synonym/s: Pachnodus velutinus Pfeiffer, 1841 (incorrect year)


Conservation Status

Last record: between 1972 and 1994

IUCN RedList status: Extinct


Hybridization with P. niger, following its expansion into P. velutinus habitat is believed to have caused the extinction of pure individuals of the latter species (Gerlach, 2009). No individuals have been recorded since before 1994, and hence it is unfortunately likely extinct.



Mahé island, Seychelles
