Material examined. ECUADOR, province of Guayas, Playas Canton, Engabao   • 1 specimen (sex undeter- mined), 130 mm; unvegetated areas near an abandoned house; 02°36′35″S, 080°26′13″W; 12 m a.s.l; Stefania S. Cuadrado, Yelsin A. Loor leg.; record observed.

Identification. This is a brown toad with an SVL of 75– 130 mm SVL. It lacks expanded discs on the fingers and has underdeveloped membranes between the toes. This species is difficult to differentiate from Rhinella marina   , but with the help of x-rays, differences in the bone mor- phology of these species can be observed in the maxillary, frontoparietal, and occipital regions (Venegas and Ron 2014; Acevedo et al. 2016).

This is a common species found in both natural and disturbed sites in this study. It was found near ponds, on roadsides, in vegetation, and, at the farm, both near the cattle enclosure and the stream. Individuals were active between 17:30 and 22:00.

Distribution. This species is distributed from southern Texas, USA, to northern Peru, west to the Andes. In Ecuador, it occurs on the coast, in western foothills of the Andes, and in the inter-Andean region ( Acevedo et al. 2016).
