Family Lecithodendriidae Lühe

The lecithodendriids are closely related to the phaneropsolids, from which they are often difficult to distinguish based on morphology.Together they form the major group of bat parasites. The synonymies indicated are based on Lotz & Font (2008a).

Bats become infected by ingesting insects harbouring the encysted metacercarial stage.
