Diagnosis: This species is, at first glance, similar to E. asperatus . However, it is easily separable using the texture/lustre of the cu - ticle (dull/microreticulate in E. asperatus ; shining/smooth in E. privisolum ). Other characteristics separating this species from other Eurynotus are: the shape of the pronotum; the presence of micropunctation on the pronotum and abdominal ventrite V; the absence of larger, setigerous punctures on abdominal ventrite V.

Description: Length 12 mm; width 6 mm. Head: Coarsely punc - tate, punctures closely spaced, separated by ≤1 puncture diam - eter. Mentum without apical notch. Eye with weak circumocular depression. Prothorax: Pronotum coarsely punctate, punctures separated by ≤1 puncture diameter, with micropunctation in interstices. Hypomeron shallowly and coarsely punctate with light sculpturing and wrinkling. Pterothorax: Elytral interval X terminating between hind coxae and elytral apex. Epipleuron narrower than width of elytral intervals 9 + 10. Elytral inter - vals not obscured by epipleuron in ventral view. Abdomen: Punctate. Abdominal ventrite V punctures separated by ≥1 puncture diameter with micropunctation in interstices; without larger, setigerous punctures intermixed. Legs: Tarsal setae black/ dark. Male pro/meso tarsi robust with large, ventral, tomentose pads. Male terminalia: Parameres missing. Aedeagus sclerot - ized dorsally, with small membranous field at base of parameres. Ventrally membranous in basal portion.

Material examined: Holotype, male (TMNH), ‘Middelberg div’. reverse side of label ‘mus?/ nov. 1935 ’, ‘Transvaal’.

Note: species is based on a single, damaged specimen; which, for the purposes of this and future studies was disarticulated and subsequently card mounted.

Etymology: Derived from the Latin privi (=separate or single) and solum (= alone, single, or lonely) in reference to the single lone specimen representing the species.

Distribution: South Africa (Fig. 10).
