Explanation of Names
Subfamily name from genus Trigonidium Rambur, 1838. This would appear to be from Greek trigonos three-cornered. Common name "trigs" appears to be from the scientific name.

Four genera in the U.S. (1)

Anaxipha - 13 species, brown/tan colored

Falcicula - 1 species, brown/tan colored and very small, with no stridulatory field

Moved from family Trigonidiidae at BugGuide on 31 January 2008. Placement in family Gryllidae follows the classification used in the Orthoptera Species File here; see Taxonomy Proposals forum topic on "Orthoptera" here.
Moved back to under its own family 2 December 2022 as per that same discussion, and the revised classification at OSF.
