Remarks

The names ‘ Entoxylon ’ and ‘ abeillei ’ were introduced three times in the literature. The first time in the second issue of Nouvelles et Faits Divers ( Ancey 1869a: viii), a supplement of L’Abeille, where the new generic name ‘ Entoxylon ’ was erected (without a description) for the sole species therein shortly described, E. abeillei (type species by monotypy). Both ‘ Entoxylon ’ and ‘ abeillei ’ take the authorship and date from that publication, dated October 1869. Ancey shortly redescribed his taxa under the same names in a different journal, Petite Nouvelles Entomologiques, published 15 Dec. 1869 ( Ancey 1869b), then provided a detailed description of both the genus and the species the following year ( Ancey 1870). All subsequent authors overlooked the first valid introduction of the two names, incorrectly citing ‘ Entoxylon ’ as first published in Petite Nouvelles Entomologiques ( Ancey 1869b), and ‘ abeillei ’ in L’Abeille ( Ancey 1870). No change in nomenclature affecting the Principle of Priority derives from this rectification.

Entoxylon strongly differs from Esarcus mainly in having anterior edge of pronotum straight, with anterolateral angles blunt, never protruding forward, scutellar shield visible, not concealed under posterior margin of pronotum, elytral interstria, if present, flat (always present, convex, in Esarcus ), pterothorax and abdomen lacking setose cavities, and other, less evident characters. In our opinion, these features fully justify the restoration of Entoxylon as a separate genus.
