Kennethia cristata De Deckker, 1979a

( Figs. 5 F-K)

Generic Differential Diagnosis (modified after De Deckker 1979a): Carapace with polygonal elevations ( Figs. 5F, G, I, L ), eye tubercles separate and well-developed. Carapace in dorsal view ( Fig. 5I ) slenderer than in Newnhamia . Carapace in ventral view ( Fig. 5L ) with plate-like expansion less broad than in Newnhamia and anterior lips less pronounced. LV with rounded dorsal margin, carrying a large crest ( Figs. 5G, J ). RV subtriangular ( Figs. 5F, K ). Soft part morphology not well-known, but most likely similar to that of Newnhamia .

Type locality and Holotype: Sweepwash Lagoon , Victoria, Australia, 38,080S 141,110E : Holotype (ò), NHMS - Xe10806 .

Material examined here: 3 females from Pleasant View Lakes, 35 km NE of Albany, southwestern part of Western Australia, collected by D.J. Cale on 22.10.2011.
