ABSTRACT: The Pantanal cat, Leopardus colocolo braccatus, has been reported for grasslands and subtropical humid forests in Brazil, Uruguay, Paraguay and Argentina. Here we report a dead Pantanal cat in the Moxos savannahs of the Beni Department of Bolivia, representing the first record of this taxon for Bolivia. This record, in combination with a reassessment of two previous records of L. colocolo in the lowlands of Bolivia, extends the distribution range of this subspecies ca.1000 km WNW from the nearest known locality in Brazil.

RESUMEN: Primer registro del gato de pantanal Leopardus colocolo braccatus en Bolivia. El gato de Pantanal (Leopardus colocolo braccatus) ha sido reportado para sabanas y bosques húmedos subtropicales en Brasil, Uruguay, Paraguay y Argentina. El objetivo de esta nota es reportar un espécimen de gato de Pantanal que fue encontrado muerto en los Llanos de Mojos en el Departamento del Beni, Bolivia. Este hallazgo es el primer registro de Leopardus colocolo braccatus en Bolivia. Este registro, en combinación con una reinterpretación de dos registros previos de L. colocolo en las tierras bajas de Bolivia, extiende en aproximadamente 1000 km al ONO el rango de distribución para la especie, desde la localidad conocida más cercana en Brasil.

The Pampas cat, Leopardus colocolo (Molina. 1782), is one of most variable species of Fe-lidae (Do Nascimento, 2010). Some authors suggest that the species could be split into three species: L. pajeros in the Andean, Chaco, Pampas and Patagonia regions; L. braccatus in lowland humid forests and grasslands of Brazil, Paraguay, Uruguay and Argentina; and L. colocolo endemic to highlands of northern Chile and forests of central Chile (western slope of the Andes; García-Perea, 1994).
In Bolivia, the reported specimens for the Altiplano and Andean mountains have been assigned to the subspecies L. p. garleppi and L. pajeros steinbachi (Anderson, 1997). There are only two confirmed historical records for L. colocolo in Bolivian lowlands (Noss et al., 2010); although the subspecies was not assigned to the confirmed observation, description and sketch at Los Fierros in Parque Nacional Noel Kempff Mercado (Emmons et al., 2006), and the identity of the collection from Los Totumus, Beni Department was considered as L. p. garleppi (Anderson, 1997). There are no previous references about Pantanal cat Leopardus colocolo braccatus in Bolivia (Garcia-Perea, 1994; Anderson, 1997; Clavijo and Ramires, 2009; Noss et al., 2010), although Emmons et al. (2006) mentioned this possibility for the Los Fierros sighting, and Wallace and Porcel (2010) included this taxon in a discussion of possible future additions to the Bolivian fauna.
Leopardus colocolo braccatus has been reported for grasslands and subtropical humid forests in Brazil, Uruguay, Paraguay and Argentina (Garcia-Perea, 1994; Nowell and Jackson, 1996; Chebez et al., 2008). Known localities for this subspecies are more common in Brazil and Paraguay (Silveira, 1995; Courtenay, 2002; Bagno et al., 2004; Do Nascimento, 2010; Go-doi et al., 2010). Its type locality is Chapada dos Guimaraes, Mato Grosso, Brazil which is the closest L. c. braccatus locality to Bolivia (Do Nascimento, 2010). The objective of this note is to report the observation and photographic record of a dead Pantanal cat in the Moxos' savannahs in the Beni Department of Bolivia.
On August 16th 2008, we found a wild cat that had just been killed by domestic dogs on a cattle ranch of Cercado Province (13° 37' S, 65° 07' W, 139 m asl, Fig. 1), northern central Beni Department. We were riding horses during our fieldwork and the dogs were accompanied a local guide that came with us. We heard the dogs fight and after a few seconds we saw the recently dead Pampas cat. We took photographs at the same place and position that the animal was found (Fig. 2); the specimen was neither collected nor measured.

Fig. 2.
Pantanal cat Leopardus colocolo braccatus minutes after the encounter in northern central Beni Department, Bolivia. Note the characteristic features of this species: "black boots" and non-ringed tail.

We compared the obtained photographs with the pictures and skins of other cats of the Leopardus genus. This photographed individual matches with the description of L. c. braccatus. The analysis of spotting variability matches with the type 3A specimen of García-Perea (1994). This type is characterized by a uniform brown "agouti" color dorsally, with some traces of dark brown rosettes on the flanks. The tail is not ringed, black at the tip. Legs are striped and ventral markings are black. Feet are dorsally and ventrally black, including wrist and ankles.
This encounter is the first record documenting the presence of L. c. braccatus in Bolivia. Some works rank L. c. braccatus as full species (Garcia-Perea, 1994; Wozenkraft, 2005; Do Nascimento, 2010). Nevertheless, a recent genetic analysis of a global cat species only recognizes one Pampas cat species, L. colocolo (Johnson et al., 2006). While our data does not provide a taxonomic solution to this debate, it does confirm the L. c. braccatus phenotype for Bolivia extending its distribution about 1000 km WNW from the nearest known locality (15° 26' S, 55° 45' W; Chapada dos Guimaraes, Mato Grosso, Brazil; Do Nascimento, 2010). This finding advises that the material of the two previous records of L. colocolo in the Bolivian lowlands must be revised in order to confirm the subspecific assignation (Emmons et al., 2006; Wallace and Porcel, 2010).

Acknowledgements. The photograph of this specimen was taken during the fieldwork of the Blue-throated Macaw Conservation Project. We thank Don Antonio Nassif for allowing us to work on his property; Don Gato and his family for their collaboration on the field; and María Lilian Villalba and Mauricio Herrera for their comments and suggestions.
