Notes
Beccaloni & Eggleton's (2011) figures of '10 genera, 47 species' presumably does not take into account Murienne's (2009) publication (they do not cite it) According to Murienne (2009: 49), the tribe Methanini certainly belongs to the Blattidae: Polyzosteriinae, as probably does the group of New Caledonian endemic genera Angustonicus, Pallidionicus, Pellucidonicus, Punctulonicus, and Rothisilpha A report has been published of an unidentified endemic "tryonicine" from New Zealand, in addition to the adventive Tryonicus parvus, but details are too sketchy at present to accept this record.
