Diagnosis.
The members of the
flavipes
species-group can be distinguished from other
Sagola
species-groups by the following combination of characters: body length
2.4–2.8 mm
; head transverse, widest across eyes (
Fig. 27e
); antennomere 1 approximately 2 times longer than wide with sparse punctures; anterior frontal fovea small round, but not externally observable because it is covered by the connected frontal rostrum (
Fig. 27e
); posterior frontal fovea elongate (
Fig. 27e
); frontal sulcus reaching length of vertexal fovea (
Fig. 27e
); ventral surface of male head with setose horn medially (
Fig. 27f
: arrow); hind wings reduced to small pads; fore femur with semicircular depression; mid-tibia bent; Male tergite IV without microtrichial patch; abdominal tergites IV–VI with discal carinae; abdominal ventrites IV–VI with basolateral foveae; present on North Island, not known from South Island (
Fig. 28
).
KEY TO SPECIES OF THE
FLAVIPES
SPECIES- GROUP
The key is mainly based on male specimens because most female specimens are indistinguishable based on external morphology.
1. Horn of ventral surface of head shorter than wide; median lobe of genitalia branched into 3 lobes, major lobe triangular (
Fig. 27c
); parameres asymmetrical and as long as median lobe (
