Diagnosis: Eurynotus capensis is one of the most widely dis - tributed (and well -identified) species in collections. Male spe - cimens are particularly easily identified by the modifications to the hindlegs (tibia with large, setose patches or grooves). Additionally, both males and females share a sinuation of abdom - inal ventrite V, which is absent in all other species. The closest species morphologically might be E. thermarum, E. barbosai, and E. graniderma (Fig. 3D, G, J); however, all three are sharply separable by size (length 8–13.5mm; width 4.75–7.5mm vs. E. capensis length 13.75–20 mm; width 7–10 mm) and males pos - sess an additional patch of setae on the midtibia (absent in E. capensis). Furthermore, E. thermarum has a more strongly nar - rowing epipleura and simple punctation of abdominal ventrite V (wider and with additional large setigerous punctures in E. capensis, respectively). Eurynotus graniderma and E. thermarum both additionally have additional microtuberculation of the elytra and/or pronotum. Redescription: Length 13.75–20 mm; width 7–10 mm. Head: Finely punctate, punctures spaced closely (≤1 puncture diam - eter) to moderately (~1 puncture diameter). Mentum with ap - ical notch. Eye with weakly impressed circumocular depression. Prothorax: Pronotum finely punctate, punctures separated by ≥1 puncture diameter. Hypomeron nearly smooth, shallowly and finely punctate with, at most, light wrinkling. Pterothorax: Elytral interval X terminates between hind coxae and elytral apex. Epipleuron subequal to elytral intervals 9 + 10. Elytral intervals not obscured by epipleuron in ventral view. Abdomen: Punctate. Abdominal ventrite V finely punctate, punctures sep - arated by ≥1 puncture diameter with larger, setigerous punc - tures intermixed. Females with median apical notch. Legs: Male hind tibiae modified with large tomentose patch. Male pro - and mesotarsi robust with large, ventral, tomentose pads. Females with fore/meso tarsi dilated or not. With wide, uninter - rupted pads on undersides of pro - and mesotarsus when dilated. Undilated female tarsi with glabrous ‘lane’ running between two rows of setae. Male terminalia: Parameres weakly tapered and rounded apically. Female terminalia: Bursa copulatrix conspicu - ously constricted in the middle (bilobate) and without sclerites, sac -shaped spermatheca with finger -like projections. Material examined: Lectotype, here designated (ZMUK): ‘Cap: bon: sp Paykull Mus: S:?t; L Helops capensis. F.; red label: TYPE; green square label; ZMUC 00508792; QR code label: 001340’. (See Supporting Information, Appendix S1 for additional ma - terial examined.) Note: As the original descriptions lack information defining the number or specificity of specimens used, a specimen from the presumed syntype series is here designated as lectotype to fix the taxonomic status of the species. Distribution: South Africa (Fig. 10).
