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(2011) figures of '10 genera, 47 species' presumably does not take into account Murienne's (2009) publication (they do not cite it)^[6]
• 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.^[7]
