Ancyrocephalus chiapanensis is a species of ancyrocephalid monogenean.

It is a parasite of the gills of the maya needlefish Strongylura hubbsi (Belonidae).

According to Mendoza-Franco, Caspeta-Mandujano and Ramírez-Martínez, the species resembles other species of Ancyrocephalus but can be differentiated by details of the male copulatory organ and of the haptor.

[1] The species was found on fish collected in the Rio Lacantún basin in the Montes Azules Biosphere Reserve, Chiapas, Mexico.
