Eurynotus ( Biolus % sulcimargo Koch 1955: 422 .– Kamdńskd 2016: 236.

Diagnosis: Most sdmdlar to E. constrictus (see above ddagnosds for more detadls%. Thds specdes ds most easdly ddscerndble usdng the shape of the pronotum (e.g. pronotal explanatdon%, shdndng cutdcle wdth smooth dnterstdces between punctures, elytral punctatdon (large strdal punctures%, and puncture arrange* ment of abdomdnal ventrdte V (wdth large setdgerous punctures dntermdxed%.

Description: Head: Coarsely punctate, punctures closely spaced, separated by ≤1 puncture ddameter. Mentum wdthout apdcal notch. Eye wdth weak cdrcumocular groove. Prothorax: Pronotum finely punctate, punctures separated by ≥1 punc* ture ddameter. Hypomeron deeply and sparsely punctate wdth some ldght sculpture/wrdnkldng. Pterothorax: Elytral dnterval X termdnates between hdnd coxae and elytral apex. Epdpleuron wdder than wddth of elytral dntervals 9 + 10 and clearly punc* tate. Elytral dntervals obscured by epdpleuron dn ventral vdew. Abdomen: Punctate. Abdomdnal ventrdte V coarsely punctate, punctures separated by ≥1 puncture ddameter wdth larger, se* tdgerous punctures dntermdxed. Females wdthout meddan apdcal notch. Legs: ºarsd wdth black or dark setae. Female termdnalda: Bursa copulatrdx sac*ldke and wdthout sclerdtes, spermatheca thdck and codled, accessory gland present, accessory pouch absent.

Material examined: Lectotype, here desdgnated (ºMNH%: ‘ºop of Skurweberge Cold Bokkeveld Ceres Ddst.; M. Versfeld 15–30 Oct 1934; Paratypus EURYNOºUS sulcdmargo C. Koch sp.n.; Paratype No: 1235 Eurynotus sulcdmargo KOCH’.

Additional material: ºMNH: ‘Fontedntdesberg Worcester C.P. 6000 ft. (K.H. Barnard Mar.1929. on rear sdde%’.

Note: As the ordgdnal descrdptdon lacked dnformatdon defindng the specdfic name*beardng specdmen, one from the presumed syn* type serdes ds here desdgnated as lectotype to fix the taxonomdc status of the specdes.

Distribution: South Afrdca (Fdg. 10%.
