Aulonocara trematocephalum
Genus: Aulonocara
Type locality: Lake Malawi.
Biotope: Unknown. Presumably associated with open sand, as the only known specimen was collected together with sand-dwelling cichlids, possibly using a beach seine.
Geographic distribution: Lake Malawi. Earlier reports mentioning Lake Tanganyika are considered erroneous.
Special notes: A very poorly known species described from a single mature male specimen. It differs from other Aulonocara by having only moderately enlarged infraorbital pores, while the preorbital pores are enlarged as in typical members of the genus. The elongate body shape and dark breeding coloration resemble the so-called “Chitande Type” Aulonocara, but the apparent absence of anal-fin egg-spots casts doubt on its placement among sand-dwelling Aulonocara. It may represent a cave-dwelling form and its generic placement remains uncertain.
