Remarks: Anaticola crassicornis is a very widespread species with some morphological variability, sometimes referred to as sensu lato ( Pilgrim & Palma 1982: 17). In a molecular study of Anaticola from a wide range of hosts, Escalante et al. (2016: fig. 1) found that all the specimens of A. crassicornis from South America formed one clade, different from the clade which includes A. crassicornis from the type host.
