description: 2. Biolus asperipennis (Mulsant and Rey) stat. res.,comb. nov.
(Figs 2B, 6G, 8B)
Eurynotus asperipennis Mulsant and Rey, 1854a: 23.– Mulsant and Rey 1854b: 169; Lacordaire 1859: 239; Gebien 1938: 414;
Koch 1954a: 280; 1954b: 2; Banaszkiewicz 2006: 63; Kamiński 2016: 235.
Diagnosis: Lacks sclerite in bursa copulatrix (present in B. analisetosus and B. granulatus). Biolus asperipennis has two puncture types on ventrite V (single type in B. omeri and B. granulatus), and golden setae on the tarsi (dark/black in B. omeri, B. sauroides, and B. brunoi). Without close inspection, B. brunoi (length 15–18 mm; width 7.5–10 mm) specimens may appear similar to smaller specimens of B. asperipennis (length 19–22 mm; width 8–11 mm); however, B. asperipennis has golden tarsal setae (black or dark in B. brunoi), a weaker circumocular depres - sion, the pronotal process is more pronounced, and the male tibiae are also at most only slightly modified in B. brunoi, while in B. asperipennis they are more strongly curved. See the diagnosis of B. brunoi below for more details.
Redescription: Length 19–22mm, width 8–11mm. Head: Punctate; punctures closely spaced, separated by ≤1 punc - ture diameter. Mentum without apical notch. Eye with weakly impressed sulcus situated around perimeter of dorsal lobe. Prothorax: Pronotum punctate, punctures separated by ≥1 puncture diameter. Hypomeron lightly sculptured/ wrinkled with small punctation and microtuberculation. Pterothorax: Elytra not costate, without macrotubercles on disc. Elytral intervals with or without microtuberculation. Epipleuron with many small, faint microtubercles. Abdomen: Finely punctate, punctures separated by>1 puncture diam - eter. Abdominal ventrite V punctures separated by ≥ 1 punc - ture diameter with larger, setigerous punctures intermixed, females with median, apical notch. Legs: Male hind tibiae slightly flattened/twisted, appearing bent. Female legs un - modified. Tarsi with golden setae. Males: pro/meso tarsi robust with large, ventral, tomentose pads. Male terminalia: Parameres ‘bottle -shaped’, strongly tapered and truncate ap - ically. Female terminalia: Bursa copulatrix without accessory pouch or sclerites.
Material examined: Lectotype, here designated (MNHN): ‘ Eurynotus? sp. cap.?; blue circle label ‘ Eurynotus asperipennis Muls cap. b. sp.?’ also with a red label with handwriting: ‘Type’.
(See Appendix S1 for additional material examined.)
Note: As the original description lacks information defining the number or specificity of specimens used, one from the presumed syntype series is here designated as the lectotype to fix the taxo - nomic status of the species and genus (Fig. 2B).
Distribution: South Africa (Fig. 9).
