Scott, 1909 (type: Pontostratiotes Brady, 1883) is a senior subjective synonym of Cerviniopseinae Brotskaya, 1963 (type: Cerviniopsis Sars, 1903) and the former is consequently reinstated at the subfamilial level. Pontostratiotes abyssicola Brady, 1883 POECILOSTOMATOIDA Poecilostomatoida are a suborder of copepods. Although it was previously considered a separate order, recent research showed it to be nested within the Cyclopoida (Khodami et al., 2017), and most families formerly included in Poecilostomatoida are now included in the suborder Ergasilida (Khodami et al., 2019) CLAUSIDIIDAE Embleton, 1901 "Copepods of the family Clausidiidae Embleton, 1901 represent an early offshoot of the poecilostome lineage within the order Cyclopoida Burmeister, 1834 (see Khodami et al., 2017).
