Type species The type species of Ampharete is Ampharete grubei Malmgren (via Code Article 69.2.2), and Ampharete acutifrons (Grube) is NOT the type species, contrary to the listing in the Hartman (1959) catalogue. The choice of type species is not clear cut, as it must be determined by subsequent designation from those nominal species first included by Malmgren. In 1865 (possibly published 1866) Malmgren included four new species (in order of presentation: Ampharete grubei, A. goesi, A. arctica, A gracilis) in the new genus Ampharete, but the first listed is Ampharete grubei, which he considered as similar to, but distinct from Amphicteis acutifrons Grube 1860, a species which Malmgren did not include recombined as one of the other Ampharete species (although he should have, given his almost synonymy of his new species A. grubei, to A. acutifrons). After some decades Hessle (1917) placed Ampharete grubei as a synonym of Ampharete acutifrons (original combination Amphicteis acutifrons), but he does not indicate a type species for Ampharete. Hartman (1959: 482), in what has been treated as the valid subsequent designation, lists the type of Ampharete as Ampharete acutifrons (Grube, 1860) (possibly Hartman was copying a previous designation). However, this is not possible as only an originally included name can be a type species of a genus (current Code Article 69.1 and earlier Codes dating back to 1905)). This is fundamental. For genus Ampharete Article 69.2.2 decides which of the originally included species is the type species. This article sets the type species to be the originally included species name that is the (junior) synonym of the species name subsequently designated as type, if this originally included species had been at the same time the only species name so synonymized out of the original names included in the genus. Hartman's (1959) checklist makes A. acutifrons senior to three names, but of these only Ampharete grubei was a name originally included by Malmgren. Thus, assuming a prior type designation to Hartman's is not found, Ampharete grubei is the type species of Ampharete. It is one of the originally included names, is an available name, and is a valid species, no longer (status fide Krüger et al. 2022) merely a junior synonym name of Ampharete acutifrons. Krüger et al. (2022) followed Hartman in retaining Amphicteis acutifrons (as Ampharete acutifrons) as type species of Ampharete, but this cannot be correct, as explained above. [G.
