Changes in subgeneric classification 2

A recent study (Sedivy et al., 2013c) proposed to unite all Hoplitis species of the subgenera Annosmia, Bytinskia, Coloplitis and Hoplitis (the “Annosmia-Hoplitis group”) in a single subgenus Hoplitis because i) Annosmia is polyphyletic in its current circumscription, ii) the cleptoparasitic Bytinskia species have evolved from the same lineage as their Annosmia hosts, iii) the most basal clade of Hoplitis is morphologically and biologically intermediate between Annosmia and Hoplitis, and iv) Coloplitis is morphologically very close to Annosmia. An alternative solution to eliminate the polyphyly of Annosmia would be the establishment of a monotypic subgenus for the most basal species of the Annosmia-Hoplitis group, Hoplitis bassana, which, however, appears unjustified owing to the morphological similarity of H. bassana with Annosmia. Merging all four subgenera into a single large subgenus results in a monophylectic taxon, which is morphologically distinctive due to a conspicuous yellowish membrane below the lateral extremity of the labrum that is present in all species.
