Etymology: Hemitaeniochromis: Greek, hemi = half + Latin, taenia, -ae = strip + Greek, chromis = a fish, perhaps a perch (Ref. 45335); brachyrhynchus: Named in reference to the abbreviated preocular region of the head; brachyrhynchus is a noun in apposition (Ref. 91204).
Environment: milieu / climate zone / depth range / distribution range
Freshwater; pelagic. Tropical
Africa: Lake Malawi (Ref. 91204).

Morphology | Morphometrics
soft rays: 9. Hemitaeniochromis brachyrhynchus is readily distinguished from its formal congener H. urotaenia, by its narrow lacrimal bone whose width, at the midpoint of the bone, is one-third of the orbit length (vs. nearly equal to the orbit length in H. urotaenia); by its snout being shorter than the orbit length (vs. longer in H. urotaenia); by its much larger eyes, the orbit length being about 36-38% of head length (vs. 22-28% in H. urotaenia); by its shorter lower jaw which is about 39-41% of head length (vs. 45-51% in H. urotaenia); and by its melanin pattern, which is composed of spots and line segments that are less well-defined than those of H. urotaenia (Ref. 91204).
Widely distributed but rare; apparently around rocks in rather deep water; possibly paedophagous diet (feeding on eggs and larvae) (Ref. 91204).
