26. moehauensis species-group

(2 species)

Diagnosis. Members of the moehauensis species - group can be distinguished from other Sagola species-groups by the following combination of characters: body length 2.5–2.8 mm; antennomere 1 approximately 2 times longer than wide with dull surface; male head triangular with projecting temporal lobe ( Fig. 64e–f ) and female head longer than wide; anterior frontal fovea oval, partially covered by frontal rostrum, and posterior frontal fovea oval ( Fig. 64f ); hind wings fully developed; abdominal tergites IV–VI with discal carinae; parameres divided ( Fig. 64c–d ).

KEY TO SPECIES OF THE MOEHAUENSIS SPECIES - GROUP

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

1. Temporal lobes of ventral surface of head flattened ( Fig. 64e : arrow); median lobe of genitalia subquadrate and phallobase of genitalia subquadrate ( Fig. 64c ); parameres narrowly divided ( Fig. 64c ) ................................ ......................... S. moehauensis new species

1′. Temporal lobes of ventral surface of head concave; median lobe of genitalia rectangular and phallobase of genitalia triangular ( Fig. 64d ); paramere broadly divided ( Fig. 64d ) .......................... S. horokakaensis new species
