A subadult individual of the monotypic genus and species Lichnochromis acuticeps collected by M. K. Oliver in 1971, only the third recorded specimen of this specialized crevice feeder. (Others have been found more recently, and occasional individuals have even been exported to the aquarium trade.)
Oliver suspects that L. acuticeps is the sister species of
Mylochromis lateristriga (i.e., that
the two shared a common ancestor not shared with any other species).
In addition to having an oblique stripe as do many other species,
these two both have long pointed heads with short jaws.
If Oliver is correct, M. lateristriga and perhaps other
species of Mylochromis should be transferred to
Lichnochromis. A similar problem exists with respect to
nearly all of the other monotypic or small genera in the "Hap" flock.
