| Popis: | Dundadela Zahradník & Trýzna gen. nov. (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.
