Three species of parasitic nematodes are redescribed based on light and scanning electron microscopical (SEM) examinations of newly collected specimens in fishes of South Carolina, USA: Dichelyne (Cucullanellus) bullocki Stromberg & Crites, 1972 from Fundulus heteroclitus (Linnaeus) (Fundulidae), Dichelyne (Dichelyne) diplocaecum Chandler, 1935 from Ictalurus furcatus (Valenciennes) (Ictaluridae), and Hysterothylacium pelagicum Deardorff & Overstreet, 1982 from Coryphaena hippurus Linnaeus (Coryphaenidae). For the first time, intraspecific variations in the number of intestinal caeca were observed in D. bullocki, as well as previously unknown males and gravid females of D. diplocaecum are described, this enabled to synonymise D. mexicanus Caspeta-Mandujano, Moravec & Salgado-Maldonado, 1999 with D. diplocaecum. Unlike most congeneric species, H. pelagicum has no double postanal papillae, as confirmed by SEM. A key to the species of Dichelyne Jagerskiold, 1902 parasitic in freshwater and brackish-water fishes in North America is provided.
