Hi, following Mike Hackstons key from 2019 (adapted from d'Assis Fonseca, 1968) one significant difference between these 2 species are the presutural achrosticals: H. impuncta has "a pair of conspicuously strong presutural acrostichal bristles" while depuncta has "at most one or more pairs of stronger hairs". I see no strong presutural achrostical bristles, so it should be H. depuncta (if we only have to choose between depuncta and impuncta). Greetings, Eric |

Hi Angelika/Reimund, Nikita is right (and I had overseen it): the single posterior bristle on the hind tibia identifies genus Phaonia. So you should better call it Phaonia sp. (and these are hard to identify, too). Greetings, Eric |
