Conservation status in IUCN Red List

Least concern.

Remarks

This is a fairly common, widespread species that has been molecularly examined as a representative of genus Monteiroconus . Historically, this species has been mistaken for M. ambiguus . However, there are constant features in shell morphology that allow a distinction between these two species, mainly the larger size and angulated, broader shoulder in the latter. In any case, a molecular examination of M. ambiguus might clarify whether the separation from M. tabidus at the species level is justified. We provisionally consider both of them as separate valid species.
