description: 1. hirtalis species-group(16 species)
Diagnosis. Members of the hirtalis speciesgroup can be distinguished from other Sagola species-groups by the following combination of characters: body length 2.0–4.0 mm; gular surface of male head with deep, round depression; male antennomeres longer than those of female, antennomere 1 at least 2 times longer than wide, with dull surface; prosternum with lateral procoxal foveae; male fore femur with semicircular depression (Fig. 4u: arrow); abdominal tergites IV–VI with discal carinae; abdominal ventrites IV–VI with basolateral foveae; parameres distinctly asymmetrical and finely punctured (Fig. 4a–p); present on North Island, not known from South Island (Figs. 5–7).
KEY TO SPECIES OF THE HIRTALIS SPECIES- GROUP
The key is based on male specimens because most female specimens are indistinguishable based on external morphology.
