NOTA
ABSTRACT
All records gathered since 1997 for the turtles
Acanthochelys pallidipectoris (8 localities), Chelonoidis
chilensis (6) and Kinosternon s. scorpioides (14), in the
Chaco ecoregion of Tarija Department, Bolivia, are
presented georeferenced and mapped. These data
contribute to precise and expand the geographic range of
these three taxa in a region affected by anthropogenic
alteration sustained over time.
Key words: Testudines, Reptilia, Gran Chaco, South
America.
RESUMEN
Registros totales y novedades en el chaco boliviano
para tres tortugas de interés conservacionista. Se
presenta la totalidad de registros reunidos desde 1997
para las tortugas Acanthochelys pallidipectoris (8
localidades), Chelonoidis chilensis (6) y Kinosternon s.
scorpioides (14), en la ecorregión del Chaco en el
Departamento Tarija, Bolivia, georreferenciados y
cartografiados. Estos datos contribuyen a precisar y
ampliar la distribución de estos tres taxa en una región
afectada por alteración antrópica sostenida en el tiempo.
Palabras clave: Testudines, Reptilia, Gran Chaco,
Sudamérica.
More than 50 per cent of extant turtle species in the
world are in one of the main IUCN threat categories:
Critically Endangered (CR), Endangered (EN), or
Vulnerable (VU) (Rhodin et al., 2021) due to a
combination of factors that vary in importance
depending on the species in question, its population, or
geographic range of distribution. In southern South
America the main pressure is the anthropogenic
alteration of natural environments for economic
purposes, e.g., substitution or destruction of vegetation
and modification of water courses sustained over time
(Cabrera, 2022) and, in lesser degree, their use as food
or for pet commerce.
The objective of this work is to publish all the
records collected to date for the chelonian species
Acanthochelys pallidipectoris (Freiberg, 1945)
(Chelidae) (Fig. 1), Chelonoidis chilensis (Gray, 1870)
(Testudinidae) (Fig. 2), and Kinosternon s. scorpioides
(Linné, 1766) (Kinosternidae) (Fig. 3) in the Chaco
Ecoregion of the Tarija Departament, southern Bolivia.
This biome extends over almost 13,800 square
kilometers of the departmental surface, representing
11 per cent of the total territory with Chaco
physiognomy of this country.
The conservation interest for these turtles lies in
the threat categories in which each one is put: A.
pallidipectoris is categorized as Endangered (EN) by
Vinke and Vinke (2022) and Near Threatened (NT) in
the Vertebrates Red Book of Bolivia (Cortez, 2009),
although it would be protected by its presence in the
National Park and Natural Area of Integrated
Management Kaa-Iya from the Gran Chaco (in Santa
Cruz Departament) (Aliaga-Rossel et al., 2020).
Chelonoidis chilensis is categorized as Vulnerable
(VU) by the IUCN (2024), as well as in the
Bol. Soc. Zool. Uruguay (2ª época). 2024. ISSN 2393-6940Vol. 33 (1): e33.1.5
