( Figs 1–16 ) Type species . Dundadela maculata sp. nov. , by original designation. Placement. Subfamily Anobiinae , tribe incertae sedis . Name derivation. Dundadela , gender feminine, dedicated to our colleague and friend Mr. Radek Dunda (*30 June, 1969–†30 March, 2020), specialist in the family Attelabidae ( Coleoptera : Curculionoidea) ( Figs 20–21 ). Description . Male. Body long oval, mostly parallel ( Fig. 1 ). Head ( Figs 2–3, 7 , 10 ) forward oriented (probably semi-prognathous in natural position), slightly transverse convex, eyes large, globular, glabrous.Antennae ( Figs 1, 8 , 12, 14 ) with eleven antennomeres. Flagellum filiform, antennomere VIII strongly transverse, last three antennomeres strongly enlarged, IX–X strongly pectinate, XI simple and robust. Pronotum ( Fig. 4 ) transverse, slightly concave dorsally, without central bump; pronotal lateral margin only partly visible, on posterior part invisible (in dorsal view). Elytra ( Fig. 1 ) parallel, without distinct humeral angles, with four very fine and indistinct longitudinal carinae (not visible on Fig. 1 ), equally distributed on elytra. Legs ( Fig. 1 ) short and slim. Anterior coxae ( Fig. 10 ) very close, touching, mesocoxae ( Fig. 9 ) very similar. Metacoxae ( Fig. 9 ) slightly separated. Metathoracic ventrite ( Fig. 9 ) with short longitudinal depression, posteriorly sharpened. All coxae conical. Claws ( Fig. 6 ) widely spaced, not bifurcate at apex. Mesosternum ( Fig. 9 ) posteriorly without hook, metasternum without tarsal grooves. Abdomen ( Fig. 11 ) with five ventrites, I with short blunt wide promontory in middle. Aedeagus symmetrical ( Figs 13, 16 ). Differential diagnosis . Dundadela gen. nov. differs from other genera of subfamily Anobiinae by antennal structure—no other genus of this subfamily has antennomeres IX and X pectinate. Only genus Megorama Fall, 1905 (subfamily Xyletininae ) has similar structure of antennae, but it has a distinctly hypognathous (orthognathous) head. Megorama (unlike Dundadela ) lacks elytral carinae. Distribution . So far known only from Madagascar .
