Members of excavata species-group can be distinguished from other Sagola speciesgroups by the following combination of characters: body small, length 1.9–2.9 mm ; frontal sulcus deep and reaching vertexal fovea ( Fig. 54e ); anterior frontal fovea round and partially covered by frontal rostrum, posterior frontal fovea keyholeshaped ( Fig. 54e ); hind wings fully developed; abdominal tergites IV–VI with discal carinae; Male tergite V distinctly depressed, with processes from anterior and posterior edge with long and dense setae between processes ( Fig. 54a–b, f ); only known from North Island ( Fig. 55 ). KEY TO SPECIES OF THE EXCAVATA SPECIES- GROUP The key is based on male specimens because most female specimens are indistinguishable based on external morphology. 1.
