Gregarines from Gromphadorina portentosa

The Madagascar hissing cockroach, Gromphadorhina portentosa, is endemic to south-western Madagascar. This species is relatively easy to culture and has been a popular both as a subject for scientific study and as a pet. Madagascar hissing cockroaches host a single gregarine species, Blabericola migrator (Clopton, 1995) Clopton, 2009. Originally described as Leidyana migrator Clopton 1995, this species is now the type species of the genus Blabericola.
