to a new description in 2021 by L. F. C. Tencatt S.
A. dos santos H.-G. Evers and M. R. Britto, Corydoras
sp. C115/116 was described in honour of the owner
of the online catfish page, Corydoras Worlds Ian Fuller,
and all the ongoing work he has accomplished to the
sub-family Corydoradinae. Captive breeding in Germany
has proved that C115 and C116 represent the same,
very variable species. It is placed in Lineage 1.
and when there is a revision they will stay as Corydoras
(Lacépède, 1803) with the type species
of C. geoffroy La Cépède, 1803.
This species was discovered by Lance Peck of the GoWildPeru
online eco travel firm.
- adult female
The new species
can be distinguished from C.
acutus and C.
having two moderate-sized dark-brown or black blotches
on caudal-fin base, one on its lateral portion and
another one on its dorsal portion, which can be variably
diffuse and/or fused with each other (vs. peduncular
blotches absent). Considering C.
filamentosus, it can be distinguished
by having the region around dorsal-fin anterior origin
generally lacking a dark-brown or black blotch, and
if such a blotch is present, it is diffuse (vs. region
around dorsal-fin anterior origin with conspicuous
dark brown or black blotch), (Tencatt et al.
is currently known only from two tributaries of the
Río Manuripe, itself a tributary of the Río
Orthon, and from a tributary of the Río Madre
de Dios, Rio Madeira basin, Peru, all close to the
border between Peru and Bolivia. (Tencatt et al. 2021).

In 1993 Hans-Georg
Evers a German aquarist and a leading light in the
aquarist world implemented the C-code system for the
German magazine DATZ due to the many undescribed species
that were entering the hobby without any name.
These number codes
(C for Corydoras) meant that the whole aquarist world
would know what each specimen was as it will be many
years before these code number species will be described
to science. When any C-number is described the corresponding
number will be retired.
stopped the C-number coding system with C159 but there
were still unidentified species still arriving in
the hobby so in 2006 Ian Fuller who runs the corydoradinae
website, www.corydorasworld.com decided to carry on
with this same coding method with his CW (Corydorasworld)
numbers. The latest number as of November 2021 is
on the Lineage system: In 2005 the book Identifying
Corydoradinae Catfish by Ian A. M. Fuller and Hans-Georg
Evers (2005) was published and at that time little
was known about the relationships among different
species in the Callichthyidae as a whole
and even less was known about the relationships among
the Corydoradinae. This was changed in 2011 with the
publication of the molecular phylogeny of the group:
Evolution, Ecology and Taxonomy of the Corydoradinae
revisited: Markos A Alexandrou & Martin I Taylor
(2011), which was published in the follow up book
in 2011, Identifying Corydoradinae Catfish Supplement
1. Our factsheet species resides in Lineage 1.
A total of 200
preserved individuals, representing over 120 different
species (including all mimetic taxa), were photographed
and used for digital landmark-based morphometric analysis
of body shape. To find out all of the lineages just

Distrbution: Peru, Río Madre de Dios drainage.
A stream tributary of the Río Manuripe in the
region locally known as “Alegría”.
is commonly found shoaling with the short-snouted
which resembles C.
knaacki Tencatt & Evers, 2016
but can be differentiated by some details in colour
pattern, especially on lateral body plates and dorsal
fin. As with C. knaacki, Corydoras
sp. CW062 can be potentially addressed to lineage
9, with the typical short-snout.
On my trip to Peru in April 2017 along with my colleagues
we collected C. fulleri (before description
C115/C116) in a swamp stream of the Rio Manuripe
with a water temperature of 24°C (75°F)
and a high p.H. value of 8.2.
Found in two tributaries of the Río Manuripe
and a tributary of the Río Madre de Dios, Rio
Madeira basin, Peru.
Male: 7.0cm (2¾ins)
Female: 7.5cm (3ins)
It has a well developed and
conical snout which frames a slightly concaved head
shape from the tip of the snout to the anterior nares.
It is distinctive owing to it having two pores within
its supraorbital canal, three series of teeth on the
upper tooth plate of the branchial arch, and, a small
fleshy flap at the corner of the mouth, ventral to
the maxillary barbel.
Two moderate-sized dark-brown
or black blotches on caudal-fin base, one on its
lateral portion and another one on its dorsal portion,
blotches variably diffuse and/or fused with each
other; absence of a dark-brown or black stripe transversally
crossing the orbit; a longitudinal dark-brown or
black stripe on the postdorsal region of flank midline,
variably fused with the lateral peduncular blotch,
some specimens with slender, longitudinally elongated,
dark-brown or black blotch on flank midline, forming
a dash-like marking, stripe or dash-like blotch
diffuse in some specimens; and region around dorsal-fin
origin generally lacking dark brown or black blotch,
or displaying diffuse blotch.
Care & Compatibility
As this is one of the longer
snouted species it will be well suited to most community
tanks. A well planted tank with a soft substrate such
as sand so they can bury their snouts while searching
The Lineage 1
species are more difficult to breed. As per Corydoras
in Corydoradinae (see Britto, 2003; Nijssen &
Isbrücker, 1980b), male specimens of C. fulleri
present lanceolate genital papilla. Additionally,
the males present a thickened pectoral spine, especially
its distal half, which is generally covered by hypertrophied
odontodes, and also formation of a segmented filament
on the tip of the spine, as illustrated by Nijssen
& Isbrücker (1983b:
81, fig. 10g).
Readily accepts a mixed and
varied diet which includes granular foods, tablet
food, frozen bloodworm and a good quality flake.
Anterior:The head end. Branchial:Pertaining
to the gills. Caudal fin: The tail. Caudal peduncle: The narrow part
of a fish's body to which the caudal or tail fin is
attached. Dorsal fin: The primary rayed fin(s)
on top of the body. Genital papilla: A small, fleshy
tube behind the anus in some fishes, from which the
sperm or eggs are released; the sex of a fish often
can be determined by the shape of its papilla. Maxillary: Pertaining to the upper
jaw. (maxillary barbels). Odontodes:Hair
- like stuctures on the body. Pectoral fins: The paired fins just
behind the head. Supraoccipital: Unpaired bone at the back of
the skull, usually with a crest.
Cory = helmeted;doras = leathery skin,(helmeted
Doras) cuirass. fulleri: Described in honour
of the owner of the online catfish page, Corydoras
Worlds Ian Fuller, and all the ongoing work he has
accomplished to the sub-family Corydoradinae.
