5441CC59FF80987FFF6FC3B2FB81F810.taxon	diagnosis	Diagnosis. This new species is distinguished from other Heilus species by the following combination of characters: length varying between 7.3 and 9.7 mm; pronotum with oblique granules; elytra with rounded macules of black velvety scales located between striae 3 and 5; aedeagus apically with two tufts of long setae laterally and one tuft centrally, bifurcate endophallite, broadest at base with two pointed projections at apex; tegmen with small triangular projection between dorsal lobes. Heilus rosadonetoi sp. nov. is most similar to H. inaequalis but can be distinguished from that species by smaller size, shorter rostrum, and position of the maculae positioned between striae 3 and 5, which in H. inaequalis are positioned between striae 3 and 4.	en	Lira, Aline De Oliveira, Sousa, Wesley Oliveira De, Marques, Marinêz Isaac (2023): Four new species of Heilus Kuschel 1955 (Curculionidae, Molytinae, Molytini, Hylobiina) from Brazil.

5441CC59FF849875FF6FC4F6FBB3FABC.taxon	diagnosis	Diagnosis. This new species is distinguished from other Heilus species by the following combination of characters: bright integument, covered with tiny whitish setae; fine, whitish, or brownish setae, without apparent maculae on elytra; oblique granules on pronotum, transverse granules of subequal width on elytral interstriae; internal sac with short spicules and bifurcate endophallite. Heilus obrieni is most similar to H. inornatus by the absence of macula but can be distinguished from that species by the form of the pronotum, laterally transverse in H. inornatus and rounded in H. obrieni, and by the thickness of the setae which are thicker in H. inornatus than H. obrieni.	en	Lira, Aline De Oliveira, Sousa, Wesley Oliveira De, Marques, Marinêz Isaac (2023): Four new species of Heilus Kuschel 1955 (Curculionidae, Molytinae, Molytini, Hylobiina) from Brazil.
