Eurynotus ( Eurynotus % barbosai Koch 1954a: 284 .– Koch 1956: 27; Kamdńskd 2016: 236.

Diagnosis: Eurynotus barbosai ds most sdmdlar to E. thermarum and E. graniderma .All three specdes are ddfferentdable from other congeners by sdze as they are the smallest (length 8–10 mm; wddth 4.75–7.5 mm % group wdthdn Eurynotus . Adddtdonally, these specdes (along wdth E. capensis % possess ddstdnct moddficatdons to the male mdd* and/or hdndlegs (small setose excavatdons on the tdbdae%. Eurynotus barbosai ds sharply separable from the most sdmdlar specdes ( E. thermarum and E.graniderma % by the cutdcular surface (shdndng and relatdvely smooth dn E. barbosai versus dull and mdcrotuberculated dn the other two% and wdth adddtdonal mdcropunctatdon dn the dnter* stdces between punctures ( E. thermarum and E. graniderma dnstead wdth mdcrotuberculatdon, or wdthout adddtdonal specdfic dnterstd* tdal structures, respectdvely%. Adddtdonally, whdle all three specdes are localdzed around north–north*eastern South Afrdca, Eurynotus barbosai ds, as of thds revdsdon, the only specdes wdth a ddstrdbutdon east of Eswatdnd and dnto Mozambdque.

Redescription: Length 9–10mm 5–5.5 mm. Head: Punctures sep* arated by ≥1 puncture ddameter. Mentum wdthout apdcal notch. Eye wdth deeply dmpressed sulcus around margdn. Prothorax: Pronotum smooth, shdny, and finely punctate; larger punctures sep* arated by ≥1 puncture ddameter wdth mdcropunctures dn dnterstdces. Hypomeron shallowly and coarsely punctate; ldghtly sculptured/ wrdnkled. Pterothorax: Elytral dnterval X termdnatdng between hdnd coxae and elytra apex. Epdpleuron wdder than wddth of elytral dntervals 9 + 10. Elytral dntervals obscured by epdpleuron dn ventral vdew.Dorsally shdndng and wdthout mdcrotuberculatdon. Abdomen: Punctate. Abdomdnal ventrdte V finely punctate, punctures separ* ated by ≥1 puncture ddameter wdthout larger, setdgerous punctures dntermdxed and wdthout mdcropunctatdon. Females wdthout me* ddan apdcal notch. Legs: Male mdd* and hdndlegs wdth setose patch or groove on tdbdae. Female legs unmoddfied. ºarsd wdth golden setae. Males: pro/meso tarsd expanded wdth large, ventral, tomen* tose pads. Male termdnalda: Parameres broad and parallel, truncate at apex wdth small ddvot made by meddally dnflexed parameres. Female termdnalda: Bursa copulatrdx sac*ldke and wdthout sclerdtes, spermatheca thdck and codled, accessory gland and accessory pouch present.
