Etymology. This species is named after the type locality, Fiordland (FD). Diagnosis. Specimens of S. fiordlandensis 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. 12f ) and the frontal rostral lobe of female head bearing a pair of blunt processes ( Fig. 12g ).

Wingless male eye approximately 1.50 times, female 0.53 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 longer than wide, 6–7 subquadrate, 8 slightly transverse, 9–10 transverse. Female antennomeres 3–8 subquadrate, 8 smaller than 7, 9–10 transverse. Thorax : Pronotum as long as wide. Wingless male elytra approximately 1.36 times, female 1.34 times longer than pronotum. Wingless male meso- and metaventrites trapezoidal, approximately 1.25 times, female 1.22 times longer than pronotum. Aedeagus : Median lobe long and slender ( Fig. 12f ).
