Beccaloni & Eggleton's (2011) figures of '10 genera, 47 species' presumably does not take into account Murienne's (2009) publication (they do no 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 RothisilphaA 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.
