RESUMO
Centrolene notostictum Ruiz-Carranza Lynch,1991 is a glassfrog known from the Cordillera Oriental of Colombia-in the Departments of Boyacá, Cundinamarca, Norte de Santander and Santander (Frost 2017)-and the Venezuelan versant of the Sierra de Perijá (Rojas et al. 2012) from 1600 to 2440 masl. Although males have been found calling on the upper surface of the leaves of ferns and Heliconeaceae on the margins of a small fast-flowing stream (Rojas et al. 2012), no quantitative description of the advertisement call of C. notostictum is currently available. During fieldwork in the Galilea Natural Forest (on the western slope of Cordillera Oriental in the municipality of Villarrica, department of Tolima, Colombia) in 2016 and 2017, we found three vocalizing males of C. notostictum. Herein, we report the first geographic record of this species for the department of Tolima and describe its previously unknown advertisement call.

The Neotropical toads of the genus Atelopus are among the most imperiled of all amphibians (La Marca et al. 2005; Gonzalez-Maya et al. 2013; McCaffery et al. 2015). Nowadays, at least 90% of the 93 listed species are threatened and more than 77% are Critically Endangered (McCaffery et al. 2015; IUCN 2016). Colombia has 44 described species of Atelopus (Frost 2017), two of these are categorized as extinct (EX) by the IUCN (2016): A. ignescens and A. longirostris, although they were recently re-discovered in Ecuador (Tapia et al. 2017), 34 as critical endangered (CR), four as endangered (EN), two as vulnerable (VU), one species has data deficient (DD) and another one has not been evaluated. Atelopus subornatus Werner, 1899, is an endemic Colombian harlequin toad described from 2300 to 2800 m.a.s.l in the municipalities of Sibaté (Alto de Sibaté and Agua Bonita) and Fusagasuga (above Fusagasuga and Tierra Negra), in Cundinamarca (Fig. 1A), on the western flank from Cordillera Oriental of Colombia (Werner 1899; Lynch 1986; Lötters 1989, 1992). The last record of this species was in 1993 (Lötters 2005), and it currently is listed as Critically Endangered by the IUCN (2016). Herein, we report the rediscovery of A. subornatus at a new locality from Tolima, Colombia (Fig. 1A), and redescribe its tadpole. The determination of the species was based on comparisons with material deposited in the amphibian collection of the Instituto de Ciencias Naturales, Universidad Nacional de Colombia (ICN-UNAL) for all species of Atelopus reported from the same general area in Cundinamarca and relatively similar to A. subornatus. The specimens are housed in the Herpetological collection of the Tolima University (CZUT-A) and amphibian collection of ICN-UNAL.
