The Patagonian opossum Lestodelphys halli is known from a few skeletons of captured animals and several isolated fragments recovered from owl pellets in Argentina. Recently, more than 300 remains (mandibles, maxillae, crania and other bones) were found in owl pellets and associated bones, comprising the largest known collection of L. halli. A detailed morphological analysis of cranial-mandibular and dental variation is reported and comparisons with other small didelphids are also made. Intraspecific variation is discussed and differential diagnosis of the species is presented.
