Family Gelyellidae

Gelyella droguei Rouch & Lescher-Moutoué, 1977, a new genus and species, is the sole species in a new family of primitive freshwater harpacticoids which tends to link together Lang's (1948) primary divisions of Polyarthra and Oligoarthra. The Key to Families (p.5) requires modification of couplet 5 as follows—

5.	P.4-P.5 absent.	Gelyellidae
	P.4-P.5 present.	5a
5a.	Distal segment of Enp. P.2 much longer than the entire Exp.	Longipediidaea)
	Distal segment of Enp. P.2 shorter than the Exp.	Canuellidae
