Etymology. This species is named after the type locality, Huia, Auckland (AK).

Diagnosis. Specimens of S. huiaensis are similar in appearance to other members of the connata group but can be distinguished by the shape of the male genitalia ( Fig. 10a ).

Description. Length 1.1–1.3 mm ( Fig. 5d–e ). Head: Winged male head approximately 1.36 times, female 1.48 times longer than wide. Winged male eye approximately 1.33 times, female 0.32 times longer than temple. Winged male antennomeres 3–8 subquadrate, 9 slightly transverse, 10 transverse. Female antennomeres 3–4 subquadrate, 5 slightly transverse, 6–10 transverse. Thorax: Pronotum as long as wide. Winged male elytra approximately 1.93 times, female 1.27 times longer than pronotum. Winged male meso- and metaventrites trapezoidal, approximately 1.70 times, female 1.17 times longer than pronotum. Aedeagus: Apical lobe of male genitalia blunt anteriorly and bent to right ( Fig. 10a ). Left paramere slightly longer than right, otherwise symmetrical, setae present anteriorly ( Fig. 10a ).

Distribution. Northern part of North Island, New Zealand ( Fig. 9 , circles).

Habitat. Specimens were collected using window traps, flight intercept traps (FIT), and by sifting leaf, log, and tree fern litter in Nothofagus , hardwood, podocarp, and broadleaf forests. Three specimens were collected among roots of Metrosideros robusta A. Cunn. (Myrtaceae) .
