Etymology. This species is named after the type locality, Northland (ND).

Diagnosis. Specimens of S. northlandensis 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. 10b ).

Description. Length 1.1–1.4 mm ( Fig. 6f–h ). Head: Winged male head approximately 1.50 times, wingless male 1.52 times, female 1.55 times longer than wide. Winged male eye approximately 1.27 times, wingless male 0.65 times, female 0.29 times longer than temple. Winged male antennomeres 3–8 subquadrate, 9 slightly transverse, 10 transverse. Wingless male antennomeres 3–6 subquadrate, 7 slightly transverse. Female antennomeres 3–5 subquadrate, 6–7 slightly transverse. Thorax: Pronotum as long as wide. Winged male elytra approximately 1.91 times, wingless male 1.26 times, female 1.24 times longer than pronotum. Winged male meso- and metaventrites trapezoidal, approximately 1.59 times, wingless male 1.15 times, female 1.18 times longer than pronotum. Aedeagus: Apical lobe of male genitalia shallow bifid, right lobe longer than left; right lobe with small process at right basal ( Fig. 10b ). Parameres symmetrical, setae present anteriorly ( Fig. 10b ).

Distribution. Northland (ND), New Zealand ( Fig. 9 , squares).

Habitat. Specimens were collected using window traps, flight intercept traps (FIT), and sifting leaf, log, and moss litter in kauri, hardwood, podocarp, and broadleaf forests.
