Antennae (Figs 1, 8, 12, 14) with eleven antennomeres, last three antennomeres strongly enlarged, penultimate two strongly pectinate, others filiform. Antennomere I robust, 1.5 times as long as wide. Antennomere II 0.25 of length of I, width 0.7 of length. III twice as long as wide and 1.4 times as long as previous. IV the same width as III, 0.55 of length of III.

Ramus on IX 2.2 times as long as length of antennomere IX, ramus on X 1.8 times as long as length of antennomere X. Rami of antennomeres IX and X widened towards the apex. Antennomere XI filiform, long elliptical, the same width as I, 4.6 times as long as wide. Pronotum (Figs 1, 4, 7) transverse, without hump, ratio of its length to maximum width 0.8, widest in the middle, strongly oblongly narrowed backwards. Surface matt-shining, finely and densely punctuated, punctures almost contiguous. Pubescence short, recumbent, white-silver, nebulous pattern. 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. Ratio of maximum length to maximum width of elytra 1.7. Surface and pubescence the same as on pronotum (Fig. 1). Scutellum small, triangular, 1.2 times as long as wide.

Lateral corner of tegmen [= Genitalbügel (Gottwald 1977), = genital stirrup (e. g. Zahradník 2006, 2013)] without promontory, rounded and broadened (Fig. 15). Female. Unknown. Variability. Differs in size of body—total length varies from 5.6 to 7.0 mm, width at base of elytra from 2.2 to 2.7 mm. Colour of body brown, to reddish-brown (possibly on teneral specimen). Differential diagnosis. The species has forward oriented head (probably semi-prognathous in natural position), antennae with 11 antennomeres, and only antennomeres IX and X strongly pectinate (see Differential diagnosis of the genus above). Etymology. From the nebulous (cloud like) arrangement of pubescence on the body, forming small rounded spots. Collecting circumstances. Three specimens of the type series (including holotype) were collected in Parc National de l´Isalo near Ranohira in Fianarantsoa province, S Madagascar (Figs 17–18). This area is dominated by a sub-arid climate. The territory consists of sandstones, shale and conglomerate (Fig. 17). The low, sparse forests are located mainly in the deeply carved canyons of the sandstone massif, and accompanied by sclerophyllous woodland with secondary grasslands and pastures in the vicinity (see also Goodman et al. 2018). These specimens from Isalo were caught at night at light near dry, dead trees (Fig. 18). Another five specimens of the type series, however, come from the vicinity of Moramanga in Toamasina province, C Madagascar. Climatic conditions are completely different here. A humid climate prevails with a much larger amount of precipitation compared to Isalo. There are remnants of degraded medium altitude moist evergreen forest. However, we do not know the collecting details of the specimens from Moramanga. Distribution.

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., Published as part of Zahradník, Petr & Trýzna, Miloš, 2023, Description of a new genus and species, Dundadela maculata, from Madagascar (Coleoptera: Ptinidae), pp. 276-286 in Zootaxa 5244 (3) on pages 277-278, DOI: 10.11646/zootaxa.5244.3.5, http://zenodo.org/record/7656391
