The unique male type specimen with tegmina slightly shorter than the pronotum is from the Andes of central Peru, Provincia de Huánuco, Conchamarca, about 2600 m. Apparently no further records are published. Rehn 1955 compared this species in his description with the only other Dichopetala species known from South America at the time, D. andeana , which has been transferred to the new genus Cohnia ( Buzzetti et al. 2010) . According to the authors a dorsal sulcus after the pronotum’s second third is diagnostic for this genus, making the metazona only half as long as the prozona. This is not very well visible in the included photos. It almost appears that the real demarcation of the metazona is at the middle of the pronotum, probably the “merest suggestion of median indentation” of the entire pronotal disk mentioned in the original description of D. andeana ( Hebard 1924) . Nevertheless, there seems to be another little sulcus, surmisable at best, and it is also just discernible on the small photos of the male holotype of D. inca in OSF. The specimen is also very similar to the photograph of a live male of Cohnia andeana in that paper. The very verbose description of Rehn does not mention any major differences between D. inca and D. andeana that would justify to keep them in different genera. Only the lateral pronotal lobes are slightly shallower in D. inca . Since the separation of Cohnia from Dichopetala seems all in all conclusive, the species is here transferred to the new genus as well.
