2. rugifrons View in CoL species-group

(4 species)

Diagnosis. The members of the rugifrons species-group can be distinguished from other Sagola species-groups by the following combination of characters: body length 2.1–3.4 mm; antennomere 1 at least 2 times longer than wide with dull surface; gular region of male head with bean-shaped opening and transversely open inside ( Fig. 8j View Fig : arrow); ventral surface of male head with pair of short carinae from posterior margin of eyes, as long as eye ( Fig. 8j View Fig ); male fore femur with semicircular depression; male mid-femur with shallow depression; male mid-tibia bent; abdominal tergites IV–VI with discal carinae; present on North Island, not known from South Island ( Figs. 9–10 View Fig View Fig ).

KEY TO SPECIES OF THE RUGIFRONS SPECIES- GROUP

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