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

Paratypes have been deposited in MUSM, KAWC, and TKPC. Diagnosis: This species is distinguished from congeners by its yellowish tan and speckled dark brown elytral coloration, the absence of carinae on the elytra, and the distinct rectangular or conical shaped elytral scales. Description. Body small, ovate, convex; mottled yellowish tan. Length (anterior of pronotum to apex of elytra) 2.19–2.88 mm. Head completely covered with depressed, light tan, ovoid scales; slight superantennal carinae; eyes surrounded by very narrow bare patch lacking scales dorsally, ventrally with scales slightly protruding; antennae stout, antennomeres densely covered in scales, setae increasingly fine toward apex, antennomeres 1–4 and 11 longer than wide, others subequal; labrum with scattered short erect orange setae apically; frons with elongate ligulate scales pointing mainly obliquely toward middle, especially prominent toward apex. Pronotum covered with densely matted setae, relatively few short, erect setae; medial cavity very deep, extending over half total length of pronotum, border well-defined except at middle anterior and posterior; two posterolateral cavities on each side deep and distinct, lateralmost cavities completely anterior to adjacent cavities. Elytra: Setation yellowish tan, speckled with dark brown in random somewhat clumped pattern, background color reddish brown; surface mostly covered in conical or flattened rectangular scales, some scales instead acutely pointed; basal 1/3 of anterolateral margin with row of long bristly setae; elytral carinae absent; ~4 rows of short erect setae on each elytron. Ventral Surface: Ventral part of pro-, meso-, and, metathorax, legs, and abdominal ventrites with appressed oval scales. Etymology: The name “globuloides” is for the similar color pattern of this species to Trigonogenius globulus Solier, for which it was initially mistaken among museum material., Published as part of Whorrall, Kyle & Philips, Keith, 2021, Six new species of spider beetles (Coleoptera: Ptinidae) in the genus Cordielytrum Philips, pp. 414-427 in Zootaxa 5040 (3) on pages 423-425, DOI: 10.11646/zootaxa.5040.3.6, http://zenodo.org/record/5531508

Cordielytrum silvae, sp. n. (Fig. 3) Holotype: Peru: Ica Region, Lomas de San Fernando. 11–12.VI.2019, S15.13°, W75.31° dung pitfall traps, 1425 m K.A.Whorrall & T. K.Philips. Holotype has been deposited in MUSM. Paratypes (16): Same data as holotype (11); PE: ICA, Prov. de Nazca Lomas de San Fernando 15°08’51.7” S 75°15’27.8” W 489m, 03.iv.2010, D. Silva y M. Vilchez (1); Prov. de Nazca Lomas de San Fernando 15°07’29.0” S 75°20’19.8” W 430m, 03.iv.2010, D. Silva y M. Vilchez (4). Paratypes have been deposited in MUSM, KAWC, TKPC, and JBHC. Diagnosis. This species is distinguished from its congeners by its relatively large size, the smooth appearance of its setation, its small bead-like scales, and its pale, brassy coloration. It can be distinguished from C. peruvianum by the larger depressions in elytral scales, more transverse pronotum, and less pronounced elytral carinae. Description. Body small, compact, subovate, convex; brass colored with a slight sheen. Length (anterior of pronotum to apex of elytra) 2.93–3.25 mm. Head completely covered with depressed, light tan, ovoid scales; pronounced superantennal carinae; antennae slender, antennomeres densely covered in scales, setae increasingly fine toward apex, antennomeres 1–4 and 11 slightly longer than wide, others subequal; clypeus distinct; labrum with short erect orange setae apically; frons with short ligulate scales pointing toward middle. Pronotum covered with densely matted setae, short, erect setae protruding from deep cavities within matted setation; medial cavity deep, broad, when viewed from above, extending nearly ½ total length, border well-defined laterally but indistinct medially, extending as a shallow groove anteriorly; two posterolateral cavities very shallow with indistinct borders. Elytra: Setation pale brassy tan, darker tan pattern medially, background color dark brown; densely covered in small, broad, ovate scales; basal ¼ of anterolateral margin with row of long bristly setae; four low longitudinal carinae extending length of each elytron, including one at suture; 4–5 rows of deep depressions between carinae. Ventral Surface: Prosternum and mesoventrite with matted scales somewhat similar to pronotum; remainder of ventral mesothorax, metathorax, legs, and abdominal ventrites with scales similar to elytra. Etymology: The name “silvae” is for Diana Silva, who collected the first specimens of this species., Published as part of Whorrall, Kyle & Philips, Keith, 2021, Six new species of spider beetles (Coleoptera: Ptinidae) in the genus Cordielytrum Philips, pp. 414-427 in Zootaxa 5040 (3) on pages 417-418, DOI: 10.11646/zootaxa.5040.3.6, http://zenodo.org/record/5531508

Cordielytrum obscurum, sp. n. (Fig. 6) Holotype: Peru: Arequipa Reg, 16 km NW Matarani, 18–21.VI.2019 S16.8754° W72.1968°, 285 m dune veg, dung pitfalls K.A.Whorrall & T. K. Philips. Holotype has been deposited in MUSM. Paratypes (24): Same data as holotype. Paratypes have been deposited in MUSM, KAWC, TKPC, and JBHC. Diagnosis: This species is distinguished from most congeners by its relatively slender shape, the more rounded shape of its pronotum, the rough, disheveled appearance of its vestiture, and the tassel-like shape of some setae. It can be distinguished from C. fimbriatum (Fig. 5) by the longer and more filiform setae of the elytral humeral angles, narrower and more sparsely spaced scales of the elytra, and darker coloration. Description. Body small, ovate, convex; mottled dark brown. Length (anterior of pronotum to apex of elytra) 2.16–2.35 mm. Head completely covered with depressed, light tan, ovoid scales; pronounced superantennal carinae; antennae stout, antennomeres densely covered in scales, setae increasingly fine toward apex, antennomeres 1–4 and 11 longer than wide, others subequal; clypeus distinct; labrum with short erect orange setae apically; frons with elongate ligulate scales pointing toward middle, especially prominent toward apex. Pronotum covered with densely matted setae, relatively few short, erect setae protruding from deep cavities within matted setation; anteriorly depressed, especially laterally, with distinct frontal ridge; medial cavity very deep, extending over half total length of pronotum, border well-defined except at middle anterior and posterior; two posterolateral cavities on each side deep and distinct. Elytra: Setation mottled tan with darker brown patches, background color dark brown; surface sparsely covered in slender scoop-shaped setae, gaps between setae showing bare elytra; basal 1/3 of anterolateral margin with row of long setae, setae mostly simple, but some variably tassel-like; five low longitudinal carinae extending length of each elytron, including one at suture, each carina with one row of short tassel-like setae with highly branched apices. Ventral Surface: Ventral part of pro-, meso, and, metathorax, legs, and abdominal ventrites with scales similar to elytra. Etymology: The name “obscurum” is from the Latin word for dark, referring to the coloration of this species. Secondarily, this name alludes to the difficulty of separating this species from others closely related., Published as part of Whorrall, Kyle & Philips, Keith, 2021, Six new species of spider beetles (Coleoptera: Ptinidae) in the genus Cordielytrum Philips, pp. 414-427 in Zootaxa 5040 (3) on pages 421-422, DOI: 10.11646/zootaxa.5040.3.6, http://zenodo.org/record/5531508
