Amphimerus lancea as a Potential Etiological Agent of Human Amphimerosis in South America: A Morphological Analysis Based on Literature Data.

Amphimerus lancea is at least one of the species involved in human amphimerosis in Ecuador. The parasite distribution and animal reservoirs are updated and the possibility of new areas of occurrence of human diseases in South America is highlighted. Future integrative taxonomic studies using material properly fixed is encouraged, which can corroborate the morphological identification here achieved and result in progress in the complex taxonomy of Amphimerus spp.
