Etymology. The specific epithet refers to the superficial similarity of this species to S. connata .

Diagnosis. Specimens of S. pseudoconnata 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. 12a ).

Description. Length 1.1–1.3 mm ( Fig. 7d–e ). Head: Winged male head approximately 1.45 times,

wingless male 1.42 times, female 1.37 times longer than wide. Winged male eye approximately 1.69 times, female 0.33 times longer than temple. Wingless male eye as long as temple. Winged male antennomeres 3–8 subquadrate, 9 slightly transverse, 10 transverse. Wingless male antennomeres 3–6 subquadrate, 7–10 transverse. Female antennomeres 3–5 subquadrate, 6–10 transverse. Thorax: Pronotum as long as wide. Winged male elytra approximately 1.92 times, wingless male 1.29 times, female 1.30 times longer than pronotum. Winged male mesoventrites trapezoidal, approximately 1.66 times, wingless male and female 1.18 times longer than pronotum. Aedeagus: Median lobe bent to right, weakly pointed apically ( Fig. 12a ). Paramere symmetrical, setae present anteriorly ( Fig. 12a ).

Distribution. Southern part of North Island, New Zealand ( Fig. 13 , triangles).

Habitat. Specimens were collected using flight intercept traps (FIT) and by sifting leaf and log litter in podocarp and broadleaf forests.
