Etymology

Subgenus Horsfallius is named in honour of Dr William Robert Horsfall in recognition of his outstanding contributions to the biology of New World mosquitoes and descriptions of the eggs of aedine species of the Nearctic Region. The name is masculine, formed from his surname and the masculine Latin suffix ‘- ius ’. Recommended abbreviation = Hor.
