Lethrinops mylodon is a species of haplochromine cichlid which is endemic to Lake Malawi where it is widespread.

[1] It is a species of deeper water over sandy substrates which feeds mainly on gastropods[3] Lethrinops mylodon has a very deep-body and a large head and eye, it can be told apart from Lethrinops gossei by the lack of a V-shaped incisionc in the upper mandible and by having less lower gillrakers, L. myodon has 12–14 compared to L. gossei which has 18–20.

Sexually active males have a golden-bronze colour and are frequently marked with distinct vertical bars, they have a bright blue head and many large yellow egg-spots on their anal fin.

[4] The populations of Lethrinops mylodon in the south eastern arm of the Lake have shown marked declines starting in the early 1970s and lasting at least to the 1990s.

They collected this form in Nkhata Bay, while the "nominate" was recorded as far north as Nkhotakota.
