About the species

Lethrinops sp. "Deep-water Altus" is an undescribed sand-dwelling cichlid recorded in Lake Malawi's South East Arm, named for its resemblance to the described species Lethrinops altus combined with a deeper depth range than that species typically occupies. It has no formal description, authority, or FishBase entry, and is one of several "deep-water" trade names applied within the genus to populations resembling shallower described species but recorded from greater depth.
