Genus Pennaria Goldfuss, 1820

Pennaria Goldfuss, 1820: 89 .

Type species. Pennaria disticha Goldfuss, 1820 , by subsequent designation by Bedot (1901).

Diagnosis. Capitate Hydrozoa having characters of the family Pennariidae .

Remarks. Confusion over the taxonomic status of the name Pennaria , the authorship of which is now attributed to Goldfuss (1820), was clarified by Gibbons & Ryland (1989). Halocordyle Stechow, 1921a is thus regarded as a junior synonym. Other issues surrounding the taxonomy and nomenclature of the genus were discussed by Calder (1988).

Numbers of species currently recognized worldwide in the genus Pennaria vary from eight ( Bouillon et al. 2006; Schuchert 2009) to two ( Daly et al. 2007), the latter estimate presumably referring to the hydroid stage only.
