N2 - Relative to the size of the country, the herpetofauna of Nicaragua remains one of the most understudied in Central America (Sunyer et al., 2014). The discovery of new herpetofaunal species in the country and distributional records for certain taxa, however, are not uncommon (Sunyer and Köhler, 2007; Sunyer et al., 2008; 2011). Isla Ometepe is located in Lago de Nicaragua, with the heavily populated land area of the Pacific versant to the west (Fig. 1).
The island consists of two volcanoes, Maderas (elev. 1,394 m) and Concepción (elev. 1,610 m), and the wide range
of habitats allow for a diverse fauna. Volcán Concepción is active and only a small amount of forest is present at
the highest elevations, but the lower elevations contain the largest expanse of dry forest on the island (2,450 ha).
Conversely, Volcán Maderas is dormant and contains expanses of lowland dry forest (1,120 ha) and humid forest
(1,640 ha), and the higher elevations support the largest expanse of cloud forest (1,166 ha) on the island (Pérez et
al., 2004). A wetland isthmus connects the two volcanoes. New species and distributional records for known species
of flora, invertebrates, and vertebrates have been reported from Ometepe, including the discovery and description
of an endemic salamander, Bolitoglossa insularis (Woodman et al., 2002; McCrary et al., 2005; Scheffrahn et al.,
2005; Sunyer et al., 2008). These discoveries are an indication of the species richness of Ometepe, and the potential
for more discoveries. The objective of our study was to conduct a herpetofaunal survey of the island, with an emphasis
on examining species richness and species distribution. We did not collect any specimens, but voucher photographs
are deposited at The University of Texas at Arlington Collection of Vertebrates Digital Collection (UTADC).
