本文系统地订正了北美Ameletus属的种，但不包括孤雌生殖的种。描述了7个新种（A. andersoni，A. bellulus、圆叶甲A. doddsianus，A. edmundsi、黑腹拟步行虫A. majusculus，A. pritchardi和A. tolae），西部和东部的物种给出了单独的检索表，提供了所有30个目前公认的两性物种的注释帐户，说明了分类特征，并提供了所有物种的分布数据。提出了以下命名上的变化：Ameletus aequivocus被认为是A. sparsatus; A，alticolus和A，celeroides junior是A. celer; A. connectina和A. connectus junior的异名。velox; A. facilis是A. vandelverensis; A.蒙塔是A. similior; A. querulus是A.牧羊人。A. A. tuberculatus受到质疑，暂时被认为与A. celer。
A systematic revision of North American species of the genus Ameletus, excluding parthenogenetic species, is presented. Seven new species are described (A. andersoni, A. bellulus, A. doddsianus, A. edmundsi, A. majusculus, A. pritchardi, and A. tolae), separate keys are given to western and eastern species, annotated accounts of all 30 presently recognized bisexual species are provided, taxonomic characters are illustrated, and distribution data are presented for all species. The following nomenclatural changes are proposed: Ameletus aequivocus is considered a junior synonym of A. sparsatus; A, alticolus and A, celeroides junior synonyms of A. celer; A. connectina and A. connectus junior synonyms of A. velox; A. facilis a junior synonym of A. vancouverensis; A. monta a junior synonym of A. similior; A. querulus a junior synonym of A. shepherdi. The specific status of A. tuberculatus is questioned and it is provisionally considered to be the same as A. celer.
