Biodiversity and distribution

Two genera containing 17 species are currently confirmed as belonging to this family, including the South American housebug. ^[1]

	Australia	New Caledonia	New Zealand
Lauraesilpha		11E [2]
Tryonicus	3E [3]	3E [4]	1A [5]

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.

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(2011) figures of '10 genera, 47 species' presumably does not take into account Murienne's (2009) publication (they do not cite it) ^[6]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