3. Eurynotus barbosai Koch

(Figs 3D, 7A, 8J)

Eurynotus ( Eurynotus) barbosai Koch 1954a: 284 .– Koch 1956: 27; Kamiński 2016: 236.

Diagnosis: Eurynotus barbosai is most similar to E. thermarum and E. graniderma .All three species are differentiable from other congeners by size as they are the smallest (length 8–10 mm; width 4.75–7.5 mm) group within Eurynotus . Additionally, these species (along with E. capensis) possess distinct modifications to the male mid - and/or hindlegs (small setose excavations on the tibiae). Eurynotus barbosai is sharply separable from the most similar species ( E. thermarum and E.graniderma) by the cuticular surface (shining and relatively smooth in E. barbosai versus dull and microtuberculated in the other two) and with additional micropunctation in the inter - stices between punctures ( E. thermarum and E. graniderma instead with microtuberculation, or without additional specific intersti - tial structures, respectively). Additionally, while all three species are localized around north–north -eastern South Africa, Eurynotus barbosai is, as of this revision, the only species with a distribution east of Eswatini and into Mozambique.

Redescription: Length 9–10mm 5–5.5 mm. Head: Punctures sep - arated by ≥1 puncture diameter. Mentum without apical notch. Eye with deeply impressed sulcus around margin. Prothorax: Pronotum smooth, shiny, and finely punctate; larger punctures sep - arated by ≥1 puncture diameter with micropunctures in interstices. Hypomeron shallowly and coarsely punctate; lightly sculptured/ wrinkled. Pterothorax: Elytral interval X terminating between hind coxae and elytra apex. Epipleuron wider than width of elytral intervals 9 + 10. Elytral intervals obscured by epipleuron in ventral view.Dorsally shining and without microtuberculation. Abdomen: Punctate. Abdominal ventrite V finely punctate, punctures separ - ated by ≥1 puncture diameter without larger, setigerous punctures intermixed and without micropunctation. Females without me - dian apical notch. Legs: Male mid - and hindlegs with setose patch or groove on tibiae. Female legs unmodified. Tarsi with golden setae. Males: pro/meso tarsi expanded with large, ventral, tomen - tose pads. Male terminalia: Parameres broad and parallel, truncate at apex with small divot made by medially inflexed parameres. Female terminalia: Bursa copulatrix sac -like and without sclerites, spermatheca thick and coiled, accessory gland and accessory pouch present.
