Iruanini Boulard, 1993 rev. stat.

Iruanaria Boulard 1993: 92 .

Lacetasini Moulds & Marshall (in Marshall et al.) 2018: 49. n. syn.

Recognising Lacetas, Iruana, Bafutalna and Murphyalna as a monophyletic group, that is the Lacetasini, raises an issue of nomenclatural priority. Marshall et al. (2018) erected the tribe Lacetasini; however Boulard (1993) erected the subtribes Iruanina Boulard, 1993 and Bafutalnina Boulard, 1993, family group names that now all become synonyms. Iruanina and Bafutalnina have date priority over Lacetasini (Articles 23.1 and 23.3, ICZN 1999). However, the names Iruanina and Bafutalnina were published simultaneously and require a decision on priority. The subtribes proposed by Boulard (1993) differ in their acoustic systems with the Iruanina having a complete sound system and the Bafutalnina lacking any mechanism to produce sound. Because Lacetas has a functioning timbal-based sound system like the Iruanina, we choose the name Iruanina as having priority, fixing it as the valid name under Article 24.2 (ICZN 1999). Thus, Lacetasini n. syn. becomes a subjective junior synonym of Iruanini rev. stat. (Article 61.3, ICZN 1999). The subtribe Iruanina is retained for the genera Iruana and Lacetas and Bafutalnina is retained for the genera Bafutalna and Murphyalna . This grouping also makes sense biogeographically as all the included genera are African.
