The Neotropical region hosts 4,225 freshwater fish species, ranking first among the world’s most diverse regions for freshwater fishes. Our NEOTROPICAL FRESHWATER FISHES data set is the first to produce a large-scale Neotropical freshwater fish inventory, covering the entire Neotropical region from Mexico and the Caribbean in the north, to the sout...

The Amazon River basin hosts the most diverse freshwater ichthyofauna in the world, and yet huge areas of the basin remain unexplored. This is the case for the upper tributaries of the rio Negro, especially those draining the Colombian territory. Here we present a list of 224 species derived from the examination of specimens collected in the Mitú r...

As a result of collections made during the dry seasons of 2013, 2014, 2015, 2017, 2018 and 2020, 247 species of fish, grouped in 14 orders and 47 families were identified. Six new records for Colombia stand out: Adontosternarchus sachsi, Trachydoras gepharti, Megalodoras guayoensis, Hypostomus rhantos, Gnatholebias zonatus and Plagioscion auratus,...
Article
Across various animal groups, adaptation to the challenging conditions of cave environments has resulted in convergent evolution. We document a Neotropical cavefish system with ample potential to study questions related to convergent adaptation to cave environments at the population level. In the karstic region of the Andes of Santander, Colombia,...

DESDE 1995 LAS COLECCIONES BIOLÓGICAS DEL INSTITUTO HUMBOLDT HAN TRABAJADO PARA LLEGAR A SER HOY EL SEGUNDO REPOSITORIO DE BIODIVERSIDAD MÁS GRANDE Y REPRESENTADO POR SU TIPO, CONVIRTIÉNDOSE EN UNA HERRAMIENTA PARA RESPONDER A LOS DESAFÍOS EN CONSERVACIÓN, GENÉTICA Y EDUCACIÓN DESDE LA INVESTIGACIÓN Y DOCUMENTACIÓN DE LA BIODIVERSIDAD.
Article
A new species of Pimelodella is described from western Andean tributaries of the Orinoco River basin. The new species differs from all congeners by a unique set of characters that includes long maxillary barbel, surpassing the dorsal lobe of the caudal fin; relatively short adipose fin (32.8–36.4 of SL); 40–42 total vertebrae; posterior margin of p...

The Amazon Basin is an unquestionable biodiversity hotspot, containing the highest freshwater biodiversity on earth and facing off a recent increase in anthropogenic threats. The current knowledge on the spatial distribution of the freshwater fish species is greatly deficient in this basin, preventing a comprehensive understanding of this hyper-div...

Across various animal groups, adaptation to the extreme conditions of cave environments has resulted in convergent evolution of morphological, physiological, and behavioral traits. We document a Neotropical cave fish system with ample potential to study questions related to convergent adaptation to cave environments at the population level. In the...

The family Trichomycteridae is one of the most diverse groups of freshwater catfishes in South and Central America with eight subfamilies, 41 genera and more than 300 valid species. Its members are widely distributed throughout South America, reaching Costa Rica in Central America and are recognized by extraordinary anatomical specializations and t...
Article
Trichomycterus spectrum is described as a new species from the Alejo cave, drained by the Ranchería River basin, in La Guajira department, north‐eastern Colombia, and is the first troglomorphic species described from this region. The new species shows an advanced degree of troglomorphisms expressed as eyes absent, long barbels and body depigmented....
Article
A new species of Hemigrammus is described from the Amazon Basin near Leticia, Departamento Amazonas, Colombia. In common with some congeners and some Hyphessobrycon spp., the new species colour pattern lacks a humeral blotch but has a caudal‐peduncle blotch. It can be distinguished from congeners with a similar colour pattern by having: a relativel...

The Tomo River runs west to east through the high savannah, known as the 'Altillanura' in eastern Colombia, to flow directly into the Orinoco River. This updated ichthyological checklist was developed by revising and deleting five bibliographic references in combination with the results of an expedition carried out in April 2017 in the lower part o...

Trichomycterus rosablanca is described as a new troglobitic catfish species from caves in southeastern Santander, Colombia. These caves are drained by the Carare River of the Magdalena River basin. The new species is characterized by the advanced condition in the typical troglomorphisms found in other congeneric cave-dwelling species, such as absen...

Trichomycterus striatus is herein redescribed, based on examination of the types and recently collected specimens, and its geographic distribution is updated. This species can be diagnosed from all other northeastern South American congeners by its variable coloration pattern consisting of a yellowish to light brown background with a black lateral...

The Cusiana River sub-basin has been identified as a priority conservation area in the Orinoco region in Colombia due to its high species diversity. This study presents an updated checklist and identification key for fishes of the Cusiana River sub-basin. The checklist was assembled through direct examination of specimens deposited in the main Colo...

Malacoglanis gelatinosus, a species of miniature catfish of the family Trichomycteridae, is only known from 4 specimens from the Amazon basin. Recently, we collected 3 specimens from the upper basin of the Meta River, a tributary of the Orinoco. This is the first record of M. gelatinosus from the Orinoco river basin, which significantly expands the...

The freshwater fish collection of the Instituto Humboldt (IAvH-P) was founded in 1971 in Bogotá and then moved to its current location in Villa de Leyva in 1995. The IAvH-P collection is one of the largest ichthyological repositories in Colombia with more than 16000 catalog lots entirely systematized in the Specify software, representing around 200...

Biological collections are sources of knowledge, particularly critical to understand life when they house specimens from megadiverse countries. However, the scientific value of biological collections is usually unknown because the lack of an explicit link between knowledge and specimens. Here we compiled 628 papers from 152 journals that used colle...

The presence of shrews of the genus Cryptotis in the most northern spur of the eastern branch of the Venezuelan Andes was initially known by two specimens collected in the Macizo de Guaramacal. Both specimens were initially assigned to C. thomasi and subsequently to C. meridensis. Posteriorly, additional specimens were collected in several localiti...

Printed checklists of species of fishes from a given basin, region or country have an important limitation, since for a group whose taxonomic diversity is not yet fully documented, its validity in most cases is limited and shortly after addition of newly described species, these checklists become immediately outdated. In the particular case of the...

The subfamily of Neotropical parasitic catfishes Stegophilinae (Trichomycteridae) is a remarkable group given its specialized feeding habits (lepidophagy, muciphagy, and necrophagy). Despite its biological interest, the systematics of this group has remained in an incipient state. Most genera lack a phylogenetic diagnosis, leading thus to taxonomic...
Article
During an ichthyological survey in the Orinoco River between 2013 and 2014, we found two individuals of the parasitic catfish Vandellia beccarii in the branchial chamber of two mature females of Potamotrygon orbignyi and one individual of an unnamed species of the also hematophagous vandelliine genus Paracanthopoma in an adult male of Potamotrygon...

A new Trichomycterus is described from a highland tributary of the río Meta (Orinoco basin), along the east flank of Páramo de Cruz Verde, Eastern Cordillera of Colombia. The new species is distinguished from most of its congeners by having a reduced posterior cranial fontanel, restricted to the parieto-supraoccipital, cleithrum pierced by several...

O reexame dos síntipos do enigmático Trichomycterus venulosus, descrito do Páramo de Cruz Verde, Cordilheira Oriental da Colômbia, nos permitiram avaliar o seu status taxonômico atual. Demonstra-se que esta espécie nominal constitui um sinônimo júnior de Eremophilus mutisii, e, portanto, não representa um caso de extinção de um peixe endêmico da Co...
