About the species

Lethrinops sp. "Yellow Collar" is an undescribed sand-dwelling cichlid of Lake Malawi, known to hobbyists and field workers only by this trade name and not by any formally published binomial. It belongs to the Lethrinops group of open-water haplochromines — slender, silvery fish with an oblique, protrusible mouth built for sifting invertebrates out of sand rather than scraping algae off rock, the niche that defines the mbuna. The name refers to a yellow band across the nape and upper operculum that breeding males show, set against the more muted grey-blue body typical of the genus. It has been recorded at scattered localities spanning much of the length of the Malawian shoreline, from Masimbwe Island in the north to Harbour Island in the south. No authority, publication year, FishBase number, or Red List status exists for this form.
