Cobertura geográfica

We conducted a scientific expedition to sample fishes in the tributaries of the Beni and Mamoré rivers: the Biata, Geneshuaya, Benicito, and Yata Rivers, as well as the Dos Naciones Lagoon. Fish were collected from 17 sites: five from the Biata River (BI 00, BI 01, BI 02, BI 03, BI 04), one from the Geneshuaya River (GE 04), five from the Benicito River (BE 01 to BE 05), five from the Yata River (YA 01 to YA 05), and one from the Dos Naciones Lagoon (2NA 01).

Cobertura taxonómica

The fish surveys resulted in an occurrence dataset comprising 529 records, of which 482 are preserved specimens. Across the 17 sites, we collected 193 species, representing 124 genera, 37 families, and 10 orders. Eighteen records were identified only to the genus level representing eight morphospecies.

Métodos de muestreo

Fishes were collected from 17 sites; five from the Biata River: BI‑00, BI‑01, BI‑02, BI‑03, BI‑04, one Geneshuaya River site: GE‑04, five on the Benicito River: BE‑01, BE‑02, BE‑03, BE‑04, BE‑05, five on the Yata River: YA‑01, YA‑02, YA‑03, YA‑04, YA‑05, and one in the Dos Naciones Lagoon: 2NA‑01. The collections occurred between September 16 to 30, 2023. We observed that floating meadows were common in the Biata River and Yata River sites, while generally absent in the Benicito River and Geneshuaya River sites. At each site, we collected fishes over a period of one to two hours. Depending on the environmental condition of the sites and time availability, we used a combination of fishing gear: cast net, hand net, small seine of 5 mm mesh size that were also used to pull out the submerged logs, hook and line, electro‑shocker, and gillnets of varying mesh sizes: 15, 25, 35, 50, 60, 80 and 90 mm, dragging the gillnets of small mesh sizes at two sites.

Área de Estudio The tributaries sampled originate in the northwestern limit of the Inundated Savannas ecoregion, then run northeast into the Cerrado ecoregion, and finally the Amazonian Forests ecoregion until converging with the Beni and Mamoré Rivers. The Inundated Savannas ecoregion presents humid savannahs most affected by annual floods. The Cerrado ecoregion features rain‑soaked savannahs and forest islands with trees re‑ sistant to frequent burning. The Amazonian Forests ecoregion presents a slightly undulating landscape in the west with outcrops of Precambrian shield in the east. Its terra firme vegetation is made up of (very) tall (30–45 m) evergreen rainforest. In the margins of these tributaries, two habitat types can be distinguished: Varzea: white water floodplains, rich in suspended inorganic material and Igapó: black‑clear water bodies, which generally do not carry inorganic material in suspension (Ibisch et al. 2003). The study area is located in the Beni River megafan, a large, fan‑shaped, partial cone of river‑laid sedi‑ ment that develops immediately downstream of the Andean Mountain front. The apex of this cone is where the Beni River exits the mountain mass into an area unconfined by valley walls. These tributaries represent previous positions of the Beni River, which has switched from one position to another over time as it builds up the megafan sediment cone (Wilkinson et al. 2006, Wilkinson et al. 2009). The Benicito River, Yata River, and Dos Naciones Lagoon are located in the Río Yata Ramsar site created in February 2013, with an area of 2,813,229 hectares in the Beni Department of the Plurinational State of Bolivia, and also overlap with a protected area: the Yata Natural Reserve (Ramsar Sites Information Service 2013).
Control de Calidad The collected specimens were fixated in 95% ethanol or 10% formalin followed by preservation in 70% ethanol. All specimens are deposited at the Centro de Investigación de Recursos Acuáticos, Universidad Autónoma del Beni José Ballivián (CIRA‑UABJB), in Trinidad, Beni, Plurinational State of Bolivia. Collections were made under license from CAR/MMAYA/VMABCCGDF/DGBAP/UGCE NO 537DI/2O23.

Descripción de la metodología paso a paso:

  1. Genus‑level identification was primarily based on the key provided by van der Sleen et al. (2018).
  2. For species‑level identification, a provisional key was created to distinguish the 1,017 species reported in the Bolivian Amazon by Jézéquel et al. (2020 v.2). To develop the provisional key and finalize identifications, we consulted the key provided by Queiroz et al. (2013) for species reported in the Madeira River Basin, as well as Eschmeyer’s Catalog of Fishes (Fricke et al. 2024) database for relevant information on the genera and species of interest. Additionally, we contacted reference‑work authors and taxonomic group experts when necessary.
  3. Finally, we consulted the GBIF occurrence datasets (2024) to confirm our new records had not been previously reported in the Bolivian Amazon or elsewhere in the country.
  4. Prior to publication on the BioFresh data portal, species identifications were updated to reflect recent genome-based classifications of Characidae (Melo et al. 2024) and Corydoradinae (Dias et al. 2025), as well as the description of a new piranha species from the Bolivian Amazon (Gallo-Cardozo et al. 2024).

Agradecimientos This study was a collaborative effort between the Universidad Autónoma del Beni José Ballivián (UABJB) and the Wildlife Conservation Society (WCS) as part of the Grupo de Trabajo para los Llanos de Moxos Expedition to the Benicito‑Biata‑Yata region in the Santa Rosa del Yacuma municipality. We express our gratitude to Gabriel Rodrigo Tarifa Escobar, Ana Camila Ramallo Unzueta, Francisco Cuaniay Rimba, and Leonardo Morales Soria for their invaluable contributions during the field campaigns. We extend our sincere thanks to Robert Wallace, the leader of the expedition, who also assisted in editing the English version of the manuscript. Our appreciation goes to the academic editor Cristiano Moreira as well as the reviewers, Fernando Dagosta and Flavio C. Lima, for their meticulous reviews and constructive feedback. Additionally, we thank copy editor Reid Miller and co‑editor‑in‑chief Robert Forsyth for their careful editing of our manuscript. We are also grateful to our colleagues and the authorities at UABJB and WCS, as well as the residents along these rivers, for their unwavering moral support.
Introducción While the main rivers of the upper Madeira Basin are thought to be well sampled ichthyologically, some areas gaps remain undersampled. These areas are mainly located in the center of Llanos de Moxos, which, due to its size and remoteness, is poorly collected (Jézéquel et al. 2020). To fill this gap, we conducted a sci‑ entific expedition to sample fishes in the tributaries of the Beni and Mamoré Rivers: Biata River, Geneshuaya River, Benicito River, Yata River, and the Dos Naciones Lagoon.
Primeros pasos

This dataset is an update to Supplemental Material Table S1 from the paper: Yunoki T, Echeverria AR, Cholima RB, Miranda Ch. G, Moreno FA (2025). Ichthyofauna (Osteichthyes, Actinopterygii) from tributaries of the Beni and Mamoré rivers in the Llanos de Moxos wetland of the Bolivian Amazon. Check List 21: 318–346.

The eventID identifies a single sampling event defined by location, time, and observation method. The occurrenceID represents a specific species observation recorded during that event, and multiple occurrences records can be linked to the same eventID. The recordNumber acts as a link for tracking changes in species identification across time or revisions, and it corresponds to the Field Number listed Table S1.
