Gromphadorhina is a genus of large, flightless cockroaches from southern Madagascar;[1] they are typical of the tribe Gromphadorhini (hissing cockroaches) and common in the pet trade.[2][1] In the older literature, the name is sometimes misspelled as Gromphadorrhina.[2]
All four Gromphadorhina species are widely kept as exotic pets, where the most well-known species is the Madagascar hissing cockroach, (G. portentosa), though this is debatable as at least two other species in the genus are commonly confused with it; G. oblongonota[3][better source needed]and G. picea.[1]
