Note:

This species has later been transferred to the genus Kiokansium Stover & Evitt 1978 by Stover & Williams (1987, p. 163), but Prössl (1990, p. 104) retained the species in Nexosispinum Davey 1979b.

The correct spelling of the species name is Nexosispinum hesperus, since a substantive is used for the specific epithet of the species name, and such an epithet is retained, regardless of the gender of the generic name (noun in apposition).

(See Williams et al., 1998).
