Tribe Colymbomorphini Blanchard, 1850

Colymbomorphitae Blanchard, 1850: 97 [stem: Colymbomorph-]. Type genus: Colymbomorpha Blanchard, 1850.

Stethaspididae H. C. C. Burmeister, 1855: 218 [stem: Stethaspid-]. Type genus: Stethaspis Hope, 1837 [placed on the Official List of Generic Names in Zoology (ICZN 1983b)]. Comment: A. B. T. Smith (2006) used " Stethaspini " as the valid name for this tribe, however, the fact that the genus Colymbomorpha is considered to be in this tribe, e.g., Houston and Weir (1992), brings the name Colymbomorphini into synonymy with Stethaspini and Xylonichini ; Colymbomorphini has nomenclatural priority and should be considered the valid name for this tribe.

Xylonychini Britton, 1957: 9 [stem: Xylonich-]. Type genus: Xylonichus Boisduval, 1835 [as Xylonychus , incorrect subsequent spelling of type genus name, not in prevailing usage (see A. B. T. Smith 2006: 166)]. Comment: incorrect original stem formation, not in prevailing usage.
