Diplotaxodon macrops, new species, differs from D. apogon, new species, in
male breeding colour and in the shorter lower jaw. These species occur sympatrically at
depths of 90 to at least 120 m in the south of the lake. Diplotaxodon aeneus, new
species, is known only from the north of the lake, and is distinguished by male breeding
colour and morphometrics. The relatively large eyes of all three species distinguish them
from other Diplotaxodon, except D. ecclesi. The holotype of D. ecclesi
differs from the three new species in its more slender body, from D. aeneus and
D. apogon in male breeding colour, and from D. macrops in its longer lower
jaw.
