([[Voss et al., 1983]]).&nbsp; The current I.C.N. Article 9 iindicates that a lectotype must be part of the original material, which can include any specimens seen by the original author, whether or not cited in the original publication, and thus not necessarily from the same sample.&nbsp; Hence, Sarjeant's lectotype cannot be invalidated for that reason.&nbsp; However, Brenner also argued that the morphology of Sarjeant's lectotype differs sufficiently from that of the holotype to constitute a separate species.&nbsp; Thus, Brenner proposed a new lectotype from the same sample as Klement's holotype and illustrated it ([[Brenner, 1988]], pl.1, figs.3a-c); this specimen was not figured in [[Klement, 1960|Klement (1960]]).&nbsp; I.C.N. Article 9.18 specifies that the choice of a lectotype by an author may be superseded if it can be shown to be in serious conflict with the protologue.&nbsp; In contrast to [[Lentin and Williams, 1993|Lentin and Williams (1993]], p.2), [[Williams et al., 1998|Williams et al. (1998]], p.148) followed [[Brenner, 1988|Brenner (1988]]).&nbsp; See also discussion under <I>Meristaulax granulata</I> (Klement).&nbsp; Age: Mid Oxfordian-Early Kimmeridgian.
