Spanglerogyrus albiventris is a whirligig beetle in the family Gyrinidae, described in 1979 from specimens collected in southern Alabama. It is the sole extant species in its genus and the only living member of the subfamily Spanglerogyrinae, which represents the earliest diverging lineage among extant gyrinids. The subfamily also includes the extinct genus Angarogyrus from the Jurassic and Cretaceous of Asia.
