E-mail: Abstract: We present an inventory of amphibians and reptiles of San Isidro de Dota, northwest of the Cordillera de Talamanca in the Central Pacific of Costa Rica.Leptodactylus The study was insularum conduced from January to August 2012 in premontane wet Coloptychonforest from 689 rhombifer m to 800 m elevation. We found a total of 56 species, including 30 species of amphibians and 26 of reptiles. It results striking the presence of the frog , uncommon above 400 m elevation, and the lizard , a very uncommon species.

This cordillera extends from temperature that ranges from 17–24°C (Solano and the Central Valley of Costa Rica to the southeast and DataVillalobos collection 2001). continuing to western Panama. The herpetofauna has been well documented only in very few sites due to the difficult access to many of the sites in this mountain ranges, hence, Fieldwork was conducted from January to August 2012, several sites explored in the past decadeet al. have brought during daily and nightly checks.

According to the distribution ranges Biodiversity inventories are needed for population given by Savage (2002) and Solórzano (2004) a list of management, conservation and education plans (Caughley possible species was performed.

We follow Savage (2002) and high degree the endemism in groups as amphibians Bolaños (2011) for the identification and taxonomy and reptiles where 27% of the species are endemic to of the specimens. The individuals were collected according this region (Savageet al. 2002). Also taking into account the to permit granted by SINAC to FB (007-2012-SINAC). decline of several populations of amphibians in Costa Vouchers were deposited in the herpetological collection Rica (Whitfield 2007), including some localities in Resultsof the Museo de Zoología, Universidad de Costa Rica (UCR). this mountain range (Lips 1998), it is relevant to make inventories regarding the composition of amphibians in the region. This list presents the first inventory of We recorded a total of 56 species (Table 1; Figures 2, 3 amphibians and reptiles of San Isidro de Dota, northwest and 4), 30 species of amphibians (3 orders, 9 families and of the Cordillera de Talamanca in Central Pacific of Costa 20 genera) and 26 species of reptiles (1 order, 13 familieset al. MaterialsRica, a site unexplored and Methods scientifically. and 20 genera). These data represent approximately Study area 12.4% of the herpetofauna of Costa Rica (Bolaños 2011), and 28% of the herpetofauna of the herpetological province of Montane Slopes and Cordillera Central located The inventory was conducted in the Reserva Forestal on the pacific slope from 600 m to 1600 m elevation Los Santos, in the Central Pacific of Costa Rica (Figure (Savage 2002). We found 73% of the species of amphibians 1), in the community of San Isidro de Dota (9°29′31.34″ proposed and 40% of reptiles proposed. 870 Arias and Bolaños | Herpetofauna of San Isidro de Dota, Costa Rica Discussion Leptodactylus insularum It was interesting the presence of The species richness of the study area was less in to 689 m elevation, a species uncommon comparison withet theal. San Vito region, in the extreme L.above insularum 400 m elevation (Savage 2002). San Isidro de southwestern of the Cordillera de Talamanca in Costa Rica Dota is located just 5 km from the nearest locality of (Santos-Barrera 2008), a site located in the same (9°27′31.10″ N, -83°56′38.36″ W, 433 m herpetological province with 67 species of amphibians and elevation), howeverColoptychon this site rhombifer is within the altitudinal range reptiles. The difference in species richness found at both considered common for this species. Also highlights the sites can be attributable to the effect of altitude on San presence of which was observed Vito region, since the sampling sites wereet located al. between but no specimens were collected, this species is know 1100 m to 1500 m, but mainly to greater sampling effort, from only four vouchers in colections (ZMB 8655, UCR 648 hours, conducted by Santos-Barrera (2008). This 3143, 6971, 15000) and a photographic voucher (Dwyer effort is reflected in the number of snakes found on the San and De Plecker 2013). The list of species presented here, Vito region, 25 against 10 on San Isidro de Dota, given that mainly with the reptiles, can significantly increase with the effort should be greater to find snakes by its secretive more effort, however, we consider that this inventory behavior (Green 1997). Instead, in San Isidro de Dota the contributes to the knowledge of the herpetofauna of the amphibian richness was higher in comparison to the San region and provides a basis for future inventories in this Vito region, 30 against 26. region and surrounding sites.
