5. pulchra species-group

(4 species)

Diagnosis. The members of the pulchra species-group can be distinguished from other Sagola species-groups by the following combination of characters: large body length 3.2–4.2 mm; antennomere 1 approximately 2.5 times longer than wide with dull surface; gular region of male head with transverse depression (Fig. 19j); ventral surface of male head with a pair of processes laterally (Fig. 19j: arrow); hind wings reduced to small pads; fore and mid-femur with semicircular depression (Fig. 19k); male mid-femur at least twice as broad as tibia (Fig. 19k); Male tergite IV without microtrichial patch; abdominal tergites IV–VI with discal carinae; female abdominal ventrite VIII triangularly produced posteriorly (Fig. 19l), ventrite IX deeply emarginate posteriorly (Fig. 19m); present on North Island, not known from South Island (Fig. 20).

KEY TO SPECIES OF THE PULCHRA SPECIES- GROUP

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

1. Median lobe of genitalia without minor lobe; broader paramere without branch from base (Fig. 19e)...... S. pulchra Broun
