Etymology: Kathetostoma: Greek, kathetos, -on = lime + Greek, stoma = mouth (Ref. 45335); binigrasella: The specific name binigrasella, from the Latin bi for ‘two’, nigra for ‘dark’ and sella for ‘saddle’ refers to the broad dark brown saddle-like bands dorsally on the body that are obvious features distinguishing this species from its New Zealand congener.
