Lyrella hennedyi (W.Smith) Stickle & D.G.Mann (including var. granulosa Grunow)

Reconsideration of the literature to identify specimens in Yap lead to a better identification of specimens reported in Lobban et al. (2012) as L. clavata Gregory (Lobban & Tharngan in prep.), based on Hustedt’s (1961–1966) key, differentiating groups on the basis of rostrate ends, including clavata , from those with rounded apices, including hennedyi . Stria densities are similar in these two species.
