Members of the baiknami speciesgroup can be distinguished from other Sagola species-groups by the following combination of characters: body length 2.2–3.1 mm ; antennomere 1 approximately 2 times longer than wide with dull surface; gular region of male head with transverse depression and with blunt process in middle ( Fig. 16i : arrow); fore femur with semicircular depression; abdominal tergites IV–VI with discal carinae; present on North Island, not known from South Island ( Figs. 17–18 ). KEY TO SPECIES OF THE BAIKNAMI SPECIES- GROUP The key is based on male specimens because most female specimens are indistinguishable based on external morphology. 1.
