Changes in subgeneric classification 4
A recent study (Sedivy et al., 2013c) proposed to unite all Hoplitis species of the exclusively nearctic subgenera Acrosmia, Hoplitina, Penteriades and Proteriades (the “Proteriades group”) in a single subgenus Proteriades because i) neither Proteriades nor Hoplitina appear to be monophyletic taxa, ii) the distinction between the Hoplitis subgenera Penteriades and Acrosmia based on the presence or absence of hooked hairs on the female proboscis is not justified as two of the five Acrosmia species also possess such hooked hairs, and iii) the four subgenera closely resemble each other morphologically, especially in the female sex. Merging all four subgenera of the Proteriades group into a single large subgenus results in a morphologically and biologically well characterized taxon, whose monophyly is strongly supported by numerous morphological characters.
