The aim of this study was to determine the morphological dimensions of adult paramphistomids collected at the local abattoir of Chachapoyas, Amazonas, Peru. The samples were collected in September 2017. Forty adult parasites of uniform size were selected and subjected to oviposition using the Dinnik and modified Dinnik techniques. Thirty eggs were randomly selected. Upon evaluation, the adult parasite in the fresh state has a reddish colour, more intense at the anterior and posterior ends, with a conical and ventrally curved body. The specimens measured 8.85 mm long, 2.27 mm wide, 0.32 mm anterior sucker and 0.60 mm posterior sucker, and the dimensions of the eggs were 126.91 µm long by 63.7 µm wide. The values obtained belong to a parasite of the Paramphistomidae family, compatible with Calicophoron microbothrioides.

El presente estudio tuvo como objetivo determinar las dimensiones morfológicas de paramfistomidos adultos recolectados en el Centro de Beneficio Municipal de Chachapoyas, Amazonas, Perú. Las muestras fueron recolectadas en setiembre de 2017. Se seleccionaron 40 parásitos adultos de tamaño uniforme a los cuales se les sometió a ovoposición usando las técnicas de Dinnik y Dinnik modificada. Se seleccionaron al azar 30 huevos. A la evaluación, el parásito adulto en estado fresco presenta un color rojizo, más intenso en los extremos anterior y posterior, con cuerpo cónico y curvado ventralmente. Los especímenes midieron 8.85 mm de largo, 2.27 mm de ancho, 0.32 mm ventosa anterior y 0.60 mm ventosa posterior y las dimensiones de los huevos fueron de 126.91 µm de largo por 63.7 µm de ancho. Los valores obtenidos pertenecen a un parásito de la familia Paramphistomidae, compatibles con Calicophoron microbothrioides.
