Apolysis efflatouni (Venturi, 1948) Gibbs, 2024

Gibbs, David, 2024, A world review of the bee fly tribe Usiini (Diptera, Bombyliidae) - Part 3: Parageron Paramonov s. lat. - Corrigendum, European Journal of Taxonomy 930 (1), pp. 314-315 : 314

The present corrigendum corrects a nomenclatural error regarding Apolysis bicolor (Efflatoun, 1945) comb. nov. in the “ Excluded species” section Gibbs (2023: 148).

Page 148: Excluded species

“ Apolysis bicolor (Efflatoun, 1945) comb. nov. ”

Should read

“ Apolysis efflatouni (Venturi, 1948) comb. nov. ”

When Efflatoun described a new species as Usia bicolor , he overlooked the fact that this name was already in use for Usia bicolor Macquart, 1855 . Subsequently, Venturi proposed a new replacement name Usia efflatouni Venturi, 1948 to solve this primary homonymy.

In my recently published work on the tribe Usiini ( Gibbs 2023) , I concluded that Usia efflatouni Venturi, 1948 belonged in Apolysis so transferred it there.With this change of combination I resurrected Efflatoun’s specific epithet, Apolysis bicolor (Efflatoun, 1945) , as I assumed it was no longer preoccupied by Usia bicolor Macquart, 1855 .

However, as a junior primary homonym Usia bicolor Efflatoun, 1945 is permanently invalid as directed by ICZN Art. 57.2 and as none of the exceptions are effective.

Venturi’s name was a proper replacement and this should be the current name for the taxon ‒ Apolysis efflatouni (Venturi, 1948) .

My action in Gibbs (2023) to place bicolor Efflatoun, 1945 in Apolysis rendered Apolysis bicolor (Melander, 1946 ‒ [originally in genus Oligodranes ]) a junior secondary homonym, and so I proposed the new replacement name, Apolysis melanderi , which remains the valid name for this nominal species.
