DESCRIPCIÓN
This is the first time the Iymnaeid Radix auricularia is reported for the Tlaxcala State, Mexico. It was found in very shallow littoral waters and deeply associated with the phanerogam Nymphoides falfax that belongs to the family Gentianaceae and which represents an important substratum for egg laying, feeding¬ and shelter against predators. Its life cicle may be annual or about fifteen months. This species is ecologically important because it is a primary consumer and possibly acts as intermediary host for certain parasites. Its biggest population density was recorded in summer and autumn when the rainy season is present and then registered temperature was between 18 and 20°C and dissolved oxygen concentration was from 7 to 7.8 mg/lt and pH was from 6.8 to 7.6, tor depths lesser than 60cm. Among its main predators are leeches, some insects larvae and aquatic birds with malacophagical habits..
