Americobdella is a genus of carnivorous leeches from southern Chile, comprising only the species, Americobdella valdiviana.
Taxonomy[edit]
Philippi, who originally classified A. valdiviana as an erpobdellid leech, noted that Americobdella valdiviana was similar to Trocheta (now synonymized with Erpobdella) "in both appearance and habit".[1] It is phylogenically between two major groups of leeches, the Rhynchobdellida and the Arhynchobdellida.[1] Recent work has suggested A. valdiviana is more closely related to the Erpobdelliformes than the Hirudiniformes.[1]
Description[edit]
Americobdella valdiviana is a predator and has only rudimentary jaws. Because of these features, it was originally classified as an erpobdellid leech.[1] A. valdiviana is grey-coloured on the dorsal side with a yellowish ventral side. Whether eyes are present in this species is a matter of debate. While Philippi originally described Americobdella valdiviana as having no eyes, other authors have indicated that eyes are indeed present.[1]
Diet[edit]
A. valdiviana feeds on earthworms.[1]
