Identification
Members of Plinthisus can be distinguished from related rhyparochromid by combinations of morphological characters including metathoracic structures, wing stridulitra, male genital capsule and claspers, phallus , and spermatheca structure. -level identification requires examination of these detailed morphological features, particularly the male genitalia and prothoracic leg structure. The genus is currently organized into at least 12 species-groups based on these characters, with five groups recognized in the Australian Region.
