About the species

Lethrinops sp. "Yellow" is an undescribed sand-dwelling cichlid recorded from the South East Arm of Lake Malawi. Unlike several related forms named for a yellow mark on one specific body part, this one carries the plainest possible version of the name, implying a broader yellow flush across the breeding male rather than a single localised patch. As with its neighbours from the same stretch of shoreline, the underlying documentation is thin, and this article treats the name as a clue rather than a confirmed description.
