Mallochia aurantia ( Santos & Aguiar, 2008) comb. nov.

Distictus aurantium Santos &Aguiar, 2008: 36–39 . Original description, figure, phylogenetic assessment.

Distictus aurantius – Yu et al. 2012 . Listed, specific epithet changed.

Comments

The considerable differences between the type species Distictus tibialis and D. aurantium Santos & Aguiar have already been stressed in Santos & Aguiar (2008: 32, 38). Those differences prompted the authors to include both species in a phylogenetic analysis based on 65 morphological characters, including 19 outgroup taxa, mostly from the group the genus was supposed to belong to, the subtribe Gabuniina ( Gabunia genus group sensu Santos 2017). The two species were recovered as sister groups and hence classified within the same genus. However, examination of further comparative material of Distictus and Mallochia shows that several species of the latter genus show character states similar to species of Distictus (see ‘Comments’ section for the genus above). The characters that consistently separate the two genera are precisely those that set D. aurantium apart from the other species of the genus, such as T1 without anterolateral tooth, fore wing crossvein 3r-m absent and vein 2Cua <0.60 × as long as crossvein 2cu-a. In fact, the species is quite similar to specimens of the Nearctic Mallochia strigosa (Cresson, 1872) . Hence, Distictus aurantium is hereby transferred to Mallochia .

Nomenclature

Yu et al. (2012) changed the neutral specific epithet aurantium to the masculine aurantius , to match Distictus , which is masculine. The ICZN (1999) states, in Article 34.2.1, that “ If a species-group name is a noun in apposition its ending need not agree in gender with the generic name with which it is combined and must not be changed to agree in gender with the generic name ”. The epithet was originally intended as a name in aposition, but this was not stated, making the emendation to aurantius acceptable. In an equivalent action, the epithet is now changed to aurantia to match Mallochia , which is feminine.
