Etymology. This species is named for the collector of the holotype, J. T. Nunn.

Diagnosis. Specimens of S. nunni are similar in appearance to those of other members of the connata group but can be distinguished by the shape of the male genitalia ( Fig. 12c ).

Winged male eye approximately 2.00 times, female 0.71 times longer than temple. Frontal rostral lobe of female head bearing pair of blunt processes with setae present ( Fig. 12g ). Frontal fovea of female head indistinct ( Fig. 12g ). Winged male antennomeres 3 subquadrate, 4–5

slightly longer than wide, 6–8 subquadrate, 9 slightly transverse, 10 transverse. Wingless male antennomeres 3 subquadrate, 4–5 slightly longer than wide, 6–8 subquadrate, 9 slightly transverse, 10 transverse. Female antennomeres 3–6 subquadrate, 7–10 transverse, 8 slightly smaller than 7. Thorax: Pronotum as long as wide. Winged male elytra approximately 1.90 times, wingless male 1.40 times, female 1.36 longer than pronotum. Winged male meso- and metaventrites trapezoidal, approximately 1.67 times, wingless male 1.31 times, female 1.22 times longer than pronotum.
