Etymology. This species is named for the collector of the holotype, Margaret Thayer.

Diagnosis. Specimens of S. thayerae 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. 10c ).

Description. Length 1.2–1.3 mm ( Fig. 6i–k ). Head: Winged male head approximately 1.47 times, wingless male 1.46 times, female 1.44 times longer than wide. Winged male eye approximately 1.31 times, wingless male 0.68 times, female 0.24 times longer than temple. Winged male antennomeres 3–8 subquadrate, 9 slightly transverse, 10 transverse. Wingless male antennomeres 3–7 subquadrate, 8 slightly transverse, 9–10 transverse. Female antennomeres 3–4 subquadrate, 5 slightly transverse, 6–10 transverse. Thorax: Pronotum approximately 1.1 times longer than wide. Winged male elytra approximately 1.79 times, wingless male 1.26 times, female 1.27 times longer than pronotum. Winged male meso- and metaventrites trapezoidal, approximately 1.63 times, wingless male 1.18 times, female 1.17 times longer than pronotum. Aedeagus: Apical lobe of male genitalia shallowly bifid, right lobe longer than left ( Fig. 10c ). Paramere symmetrical, setae present anteriorly ( Fig. 10c ).

Distribution. Auckland (AK) and Coromandel (CL) ( Fig. 11 , triangles).

Habitat. Specimens were collected using window traps, flight intercept traps (FIT), Malaise traps, pitfall traps, and by sifting leaf, log, and moss litter in Nothofagus and Cyathea forests.
