Elpezoe
The Treatise (Benson et al., 1961) suggests that Elpe has been replaced by Elpezoe. These species were found in Dalvé (1948) as species of Elpe. It is unknown whether these are indeed currently placed within Elpezoe, but it is doubtful, given that the Treatise lists Elpezoe as a Devonian genus of Europe.
