The Hourglass Treefrog Dendropsophus ebraccatus While conducting a herpetological survey on 24 (Cope, 1874) occurs from southern Veracruz and March 2018, we found and photographed an adult male northern Oaxaca, south into Chiapas, Tabasco, and the Dendropsophus ebraccatus calling in the moist leaf litter Yucatán Peninsula in Mexico (Campeche, Quintana at Área de Protección de Flora y Fauna “Otoch Ma´ax Roo), and further south into northern and Yetel Kooh” in the Mayan community of Punta Laguna, . Further south, the range is discontinuous with one Chemax Municipality, Yucatán, Mexico (20.6469°N, or two localities in , several known localities 87.6340°W; WGS84; elev. 27 m; Fig. 1). This area of in , and then a continuous distribution conservation was decreed by the Mexican government from through into and in 2002 (Document Department of Urban Development northwestern , at low elevations from sea level and Ecology, SEDUE. DS. 142. II.3. 110) and owned to 1600 m (Lee, 1996; Campbell, 1998; Calderón et al., by Chemax Municipality, in the northeastern region 2003; Jungfer et al., 2010; Frost, 2018). It inhabits humid of the state, located 18 km north of the archaeological tropical forest, including primary and secondary forest site of Cobá and 26 km south of Nuevo Xcán, Quintana and forest edge, but also heavily disturbed areas where Roo (CONANP, 2006). It encompasses 5367 ha, of most of the forest is secondary. Breeding occurs during which more than half (61.45%) is covered mostly by the rainy season with aggregations of several hundred medium subdeciduous forest and 32.2% by secondary males calling from low emergent vegetation at the edge of ponds. The eggs are placed on leaves overhanging temporary (and sometimes permanent) ponds; the tadpoles develop in water (Lee, 1996; Campbell, 1998; Jungfer et al., 2010).

Treinen-Crespo et al. vegetation with different degrees of recovery; only 2.92 Institute of Statistics, Geography and Information % corresponds to “milpa” (traditional crops of corn, Technology of Mexico (INEGI by its Spanish initials), bean, and pumpkin) and 2.66% to water bodies, as well our record lies in Chemax Municipality, Yucatán State as pastureland and areas subject to low forest flooding (CONABIO, 2008; INEGI, 2012). We suggest that (Ramos-Fernández et al., 2004). increasing the sampling efforts in that area will improve Our record is located 111.2 km NE (by air) from the our understanding of the actual distribution of this closest reported locality, 13.3 km NE of Felipe Carrillo species, especially in areas with surface water bodies Puerto (19.6906°N, 87.9598°W; WGS84) on the road to that may harbour larger populations of D. ebraccatus Vigía Chico in the Felipe Carrillo Puerto Municipality, in Yucatán State. Frost (2018) mentioned that the Quintana Roo. This specimen was collected on 2 October population in central Quintana Roo was isolated from 1976 (Brown, 2018; GBIF, 2018; Fig. 2). Additionally, the southernmost nearby populations in Calakmul, four specimens from this locality (KU 171304–07) were Campeche (Calderón et al., 2003). However, with deposited in the KUBI Herpetology Collection (Lee, greater search effort it is likely that the gaps in the 1996; Brown, 2018). The observation reported herein distribution will be proven to be artefacts of collecting. represents a new record for Yucatán State. According to This new record adds D. ebraccatus to the list of species the “Borders and Labels” layer of Google Earth Pro (7.1 of Área de Protección de Flora y Fauna OMYK and to version), “State Political Division Layer” (Version 2. the herpetofauna of the Yucatán State (Lee, 1996, 2000; Scale 1: 250000), and “Municipal Geostatistical Areas CONANP, 2006; Köhler, 2011; González-Sánchez et Layer” (Version 6.0.
