Formerely CW006 but has now
been described by Rebecca Bentley, Steven Grant and
Dr. Luiz Tencatt and named after Steven Grant's daughter
Bethan. This species is often found with the so-called
Corydoras sp. "Super arcuatus" (CW036)
which is now Corydoras
arcuatus and is similar
looking to Corydoras
narcissus but has a shorter and squatter body. There is
also another similar form from Brazil. Description:
A new Corydoras is described from the Blanco
and Ucayali river basins in Peru. The new species
can be distinguished from its congeners by having
the following features: (I) posterior margin of dorsal-fin
spine with laminar serrations directed towards the
origin of the spine; (II) a long, wide, arched, and
continuous black stripe, which runs parallel to the
dorsal profile of the body, extending at least from
the region below anterior origin of dorsal fin to
the anterior half of the ventral caudal-fin lobe;
(III) a black stripe transversally crossing the eye,
forming the typical mask-like blotch; mask clearly
not fused to arched stripe in most specimens; some
specimens with mask separated from arched stripe by
a thin line around the suture between neurocranium
(in the region composed by the posteroventral margin
of parieto-supraoccipital plus the posterodorsal margin
of the compound pterotic) and first dorsolateral body
plate; (IV) posterior margin of pectoral-fin spine
with laminar serrations directed towards the origin
of the spine; (V) pointed snout, presenting a long
mesethmoid, with anterior tip larger than 50% of the
entire length of the bone; and (V) ventral surface
of trunk covered by small, non-coalescent platelets.
Lineage: Placed in Lineage 8 sub
clade 4 which comprises the "intermediate long-snouts"
with deeper bodies. It also includes Brochis
in sub-clade 1 which was synonymised with Corydoras
by Britto in 2003 but in time there will be a revision
which will resurrect Brochis (Cope, 1871)
to full genera again. Aquarium Care:
This is akin to most of this genus, very peaceful,
and would be best housed with small to medium tank
mates such as Tetras, Rasboras and Danios or in a
species tank for breeding purposes. Diet:
A good quality flake food and tablet food for adults
with sporadic feedings of frozen or live food will
keep your Corydoras in good health.
