Grasping ecological opportunities: not one but five paedophagous species of Haplochromis (Teleostei: Cichlidae)
in the Lake Edward system. by Vranken, Van Steenberge & Snoeks. Hydrobiologia 2018.

Abstract: The Lake Edward system in Eastern Central Africa, including Lakes Edward and George
and their associated rivers, is home to a species assemblage of endemic haplochromine cichlids. Currently,
36 of these species have been formally described, while it is estimated that the system may
harbour a total of 60 species. Species flocks of haplochromine cichlids are morphologically and ecologically
very diverse and have radiated into many specialised trophic niches. Paedophagy is the feeding
on eggs and larvae. In Haplochromis, most paedophages steal fry and eggs from the buccal cavities of
mouthbrooding female cichlids. Hitherto, one formally described species with this diet is known from
the Lake Edward system: Haplochromis taurinus. We performed a morphometrical revision of all species of
Haplochromis from this system with a morphology that suggests a paedophagous diet: long oral jaws set
with small teeth. Sixty-eight specimens were studied by taking 28 measurements and 20 counts and by
performing stomach content observations. We discovered that H. paradoxus also had a paedophagous diet.
Our analyses further revealed the presence of three new species: H. gracilifur sp. nov., H. molossus sp.
nov., and H. relictidens sp. nov. All five of these species were described or redescribed.

Photo of all three newly described species, plus photos of H. taurinus and H. paradoxus. Very interesting species for sure.
