Type-genus.

Celatoblatta Johns, 1966.

Diagnosis.

See Johns’ (1966) diagnosis for genus Celatoblatta .

Johns (1966) erected the genus Celatoblatta for a number of blattid cockroaches found in New Zealand and placed it in Blattinae based on general habitus and the appearance of the legs. On the other hand, Mackerras (1968a) considered Celatoblatta closely related to Temnelytra ( Polyzosteriinae : Methanini ). It should be noted that Johns (1966) stated that his Celatoblatta brunni is not the same species as McKittrick’s (1964) Platyzosteria brunni , see 4.6.5.1.

Princis (1970, 1971) included several species from Australia and New Guinea in Celatoblatta , making Austrostylopyga a junior synonym, and also added several species from New Caledonia. Celatoblatta sensu Princis was polyphyletic in all our analyses, split into three widely separated groups. One of these groups corresponds to Celatoblatta sensu Johns as it only contains species from New Zealand (here Celatoblatta vulgaris , Celatoblatta sp. CK77, Celatoblatta sp. CK109). Celatoblatta sensu Johns is a coherent phylogenetic group and forms a distinctive lineage (Chinn and Gemmel 2004; Goldberg and Trewick 2011; this paper), including C. brunni , which was included in Maoriblatta by Princis (1966: p. 543), although Princis later (1967: p. 710) changed this in his corrections and placed C. brunni in Celatoblatta . We will henceforth refer to Celatoblatta sensu Johns as Celatoblatta s.s. In our analyses, Celatoblatta s.s. was consistently placed within Polyzosteriinae as sister to Polyzosteriini + Rothisilphini . Thus, we move Celatoblatta s.s. from Blattinae to Polyzosteriinae , and place it in a separate tribe, Celatoblattini , so far consisting only of Celatoblatta s.s. See section 4.6.5.1. for our reasons for not including Celatoblattini and Rothisilphini in Polyzosteriini .
