Justification
EOO 6762 km². Historically, this species is known from 14 locations, but most have imprecise locality descriptions, and it is not possible to infer whether they are still extant or not. There are no recent collections, but the species may be overlooked. Field surveys are urgently needed to relocate it in the wild. Although a large proportion of its habitat has been lost, many fragments remain where it could potentially persist.

Threats
At least 63% of this species' habitat has been lost to crop cultivation, and remaining habitat consists mostly of small, isolated fragments. This annual species' resilience to disturbance is not known.
Population

A relatively widespread, but very poorly known species, last recorded in 1975. It may be overlooked, or possibly a localized habitat specialist. Field surveys are needed to gain a better understanding of its habitat requirements, abundance and response to disturbance. The population trend is not known.
