Princisia vanwaerebeki, commonly known as the vibrant hisser,[1] is a large, flightless species of hissing cockroach in the family Blaberidae, and the only member of the genus Princisia.

[2][3] It is endemic to southeastern Madagascar,[2][3] and sometimes seen in the pet trade.

[4] It is named in honour of two people: Karlis Princis for the genus name and Daniel van Waerebek, a helminthologist in Antananarivo, for the specific (species) name.

[3][5] It is a very large species, growing between 5.6 and 10 cm (2.2 and 3.9 in) in length.

[4] It is one of several species of cockroach sometimes infected by Blabericola migrator, a parasitic alveolate.
