Se describe la dieta de Phyllodactylus reissi, un geckónido nocturno común que se distribuye desde el sur de Ecuador hasta el centro del Perú. Se capturó un total de 15 individuos en la Zona Reservada de Tumbes, en construcciones localizadas en Quebrada Faical, El Caucho y Bocana Murciélago. El análisis del contenido estomacal determinó que P. reisii consume seis tipos de presas, principalmente Coleoptera y Blattoptera. El promedio de presas por estómago es de 3,0 con un rango entre 1 y 9 presas. La longitud promedio de las presas fue de 8,98 mm, con un rango entre 1 y 25 mm, y un volumen promedio de 61,97 mm 3 y un rango entre 0,13 y 670,8 mm 3. La longitud hocico-cloaca y la longitud del hocico no se relacionan significativamente con la longitud y volumen promedio de las presas. Phyllodactylus reissi presenta hábitos generalistas en cuanto a dieta y una tendencia a consumir presas de tamaño mediano en la Zona Reservada de Tumbes.Palabras clave: Phyllodactylus reissi, Gekkonidae, dieta, Zona Reservada de Tumbes, Perú. AbstractThe purpose of this paper is to describe the diet of Phyllodactylus reissi, a nocturnal common gecko distributed from southern Ecuador to central Perú. A total of 15 individuals were captured inside buildings at Quebrada Faical, El Caucho and Bocana Murciélago in the Zona Reservada de Tumbes. Coleoptera and Blattoptera were the dominant preys from a total of six prey types found in stomachs. The number of prey per stomach were between 1 to 9, with 3 preys in average; the prey length average was 8,98 mm with a range of 1 to 25mm; the prey volume average was 61,97 mm 3 with a range of 0,13 to 670,8 mm 3 . The snout-vent length and snout length were not significantly related with average prey lengths and volumes. Phyllodactylus reissi has generalist habits with respect to diet and shows a tendency to consume medium-sized preys in the Zona Reservada de Tumbes.

The diet of Ameiva edracantha Bocourt 1874, a terrestrial diurnal teiid lizard distributed in northwestern Peru and southwestern Ecuador is described for the first time. Stomach contents of fifteen individuals collected from quebrada La Angostura were analyzed. Lepidopteran larvae, coleopterans, orthopterans and spiders were the dominant preys in the lizard’s diet. Snout-vent length and head length, width and height were not correlated to prey length, width and volume. Other parameters such as profitability and prey target selection could be involved in prey selection by A. edracantha.

Thecadactylus solimoensis is an abundant nocturnal gekkonid species in Peruvian Amazonia. However, basic aspects on its ecology remain unknown. Here, we present data on diet, morphology, reproduction and nematode parasitism assessed in museum specimens.
