Biology and notes. Thompson et al. (1976) recorded Toxomerus dispar from Chile. Throughout this study we did not find museum specimens or collected specimens of this species. Thus, there is not enough evidence for the species to actually occur in Chile and it should be considered as a doubtful record.

Conservation status. Not evaluated because this species is a doubtful record for Chile.
