This Australian cockroach is widespread in coastal southern Queensland and has been established in New Zealand for several years. It is now moderately widespread within Auckland city: Mission Bay, Mt Wellington and Blockhouse Bay. It is black and very similar in size to the native Maoriblatta rufoterminata from which it may be distinguished by its narrow white band (arrowed) midway along the otherwise black antennae. The males have relatively long, narrow, pointed remnants of tegmina (arrowed - compare photo with that of Maoriblatta rufoterminata). Females and juveniles have no remnants of tegmina.
