Justification of Red List category
This species has not been recorded since the nineteenth century (only the type-specimen taken in 1850 has any locality information), the habitat at the type-locality has been almost completely destroyed, and searches specifically for this species in the area in 1980 failed. However, it cannot yet be presumed to be Extinct because there was an unconfirmed record in 1976, and further searches of remnant habitat are required. Any remaining population is likely to be tiny, and for these reasons it is treated as Critically Endangered (Possibly Extinct).
