Possibly Extinct Candidate? Rationale for the Red List Assessment C. absus is a common species with an extremely widespread distribution. The taxon is is known to occur within the protected areas network and is not known to be experiencing and major threatening processes at present. C. absus is thus rated as Least Concern.
