( Figs. 11g , 12g , 14 )

Type Material. Holotype. NEW ZEALAND: Northland: 1♂ ( AMNZ), aedeagus dissected and mounted in balsam on a clear plastic card, “ New Zealand: ND: North Cape Area Taputaputa Bay 30IV1968, J.L. Bertrand ”, “ HOLOTYPE Sagola ranatungae Park and Carlton 2013 ” . Paratype (1 female). NEW ZEALAND: Northland : 1♀ ( AMNZ), same data as holotype .

Anterior frontal fovea an inverted triangle. Posterior frontal fovea elongate. Eye small and prominent, one-third length of temple. Thorax: Prosternum as long as wide, widest at midpoint. Elytra approximately triangular ( Fig. 11g ). Meso- and metathorax trapezoidal, longer than wide. Abdomen: Male tergite IV without microtrichial patch. Aedeagus: Median lobe weakly bent and longer than left paramere ( Fig. 12g ). Phallobase of median lobe asymmetrical and triangular ( Fig. 12g ).
