The key is based on male specimens because female specimens are indistinguishable based on external morphology.

1. Temporal lobes of ventral surface of head flattened (Fig. 64e: arrow); median lobe of genitalia subquadrate and phallobase of genitalia subquadrate (Fig. 64c); parameres narrowly divided (Fig. 64c) ................................ ......................... S. moehauensis new species

1′. Temporal lobes of ventral surface of head concave; median lobe of genitalia rectangular and phallobase of genitalia triangular (Fig. 64d); paramere broadly divided (Fig. 64d) .......................... S. horokakaensis new species
