Description Aegidiellus comprises small to medium-sized beetles (body length 7–11 mm ), brown to black coloured, without pattern. Mandibles subsymmetrical, small, without lateral processes, protruding past anterior margin of frontoclypeus in dorsal view. Frontoclypeus without tubercles, horns or ridges. Propleurae with carinae separating anterolateral areas from basal area. Pronotum of ‘major’ males with deep excavation in the middle and two horn-shaped, lateral pronotal processes directed somewhat anteriorly. In ‘minor’ males, pronotal and head armature less developed: lateral pronotal processes short, tubercle-shaped and anterior frontoclypeal process carina-shaped. In females, pronotum impressed anteriorly on disc and with a tubercle medially on anterior margin. Scutellum narrowly rounded apically, about 1/ 10 length of elytra. Elytra convex, with marked humeral and apical umbones. Elytral striae as longitudinal rows of punctures; sutural stria normally distinct as a depressed furrow in apical half of elytron; elytra without elevated, longitudinal keels or smooth stripes on disc. Wings fully developed in all species. Metepisternon elongated, its posterior angle slightly triangular and situated in distinct concavity of epipleuron. Mesocoxal cavities connected by a hole. Protibiae with three strong outer teeth in both sexes, with a smaller, medial tooth in majority of males. Mesotibiae without tuft of setae ventroapically. Plectrum widely triangular, rounded apically, with a few sensory setae. Stridulatory file with 100–110 fine, slightly curved carinae (carinae counted according to Frolov and Akhmetova (2016)) . Phallobase tubeshaped with strongly sclerotized ventral side but without differentiation of ventral and dorsal sclerites; ventroapical plate absent. Parameres symmetrical, apices with short, dense setae. Spiculum gastrale wide, triangular. Endophallus without armature. Subcoxites with sparse, long setae medioapically. Coxites triangular, with row of short spinules mediobasally and long, sparse setae apically. Stili not separated from coxites.
