The Tryonicidae are a family of cockroaches.

Biodiversity and distribution

Two genera containing 17 species are currently confirmed as belonging to this family.[1]

An example of Tryonicus parvus found in Auckland, New Zealand. They are common under logs and planks lying in gumland scrub. Are capable of emitting an unpleasant smell when handled.An example of Tryonicus parvus found in Auckland, New Zealand. They are common under logs and planks lying in gumland scrub.

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(2011) figures of '10 genera, 47 species' presumably does not take into account Murienne's (2009) publication (they do not cite it)[6]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