Type Material. Holotype. NEW ZEALAND: Northland: 1♂ ( NZAC), aedeagus dissected and mounted in balsam on a clear plastic card, “ NEW ZEALAND: ND Waipoua State Forest , vic. Wairau Summit, 460m, 1.xii.1984 hdwd.- podocarp forest A.Newton / M.Thayer 683”, “pyrethrin-fogging fungusy logs”, “ HOLOTYPE Sagola gimmeli Park and Carlton 2013 ”.

Etymology. This species is named for LSAM alumnus, lab mate, and enthusiastic supporter of this study, Matthew L. Gimmel.

Diagnosis. This species can be distinguished from the other species of the auripila speciesgroup by the following combination of characters: larger body, length 2.4 mm; antennomere 1 approximately 2 times longer than wide, with dull surface; gular region of male head depressed and densely setose; frontal sulcus deep, reaching vertexal fovea; shape of genitalia unique to species.

Description of Male. Length 2.4 mm. Body brown, antennae, legs, maxillary palpi, and elytra paler ( Fig. 37g ). Head: Round, widest across eyes ( Fig. 37g ). Gular region depressed and densely setose. Antennomere 1 approximately 2 times longer than wide, with dull surface, 2–3 subquadrate, 4–5 longer than wide, 6–10 subquadrate. Frontal sulcus deep, reaching end of head from frontal rostrum. Anterior frontal fovea round and partially covered by frontal rostrum, posterior frontal fovea elongate. Eye small, approximately one-third length of temple. Thorax: Prosternum as long as wide, widest at midpoint. Elytra approximately triangular ( Fig. 37g ). Meso-and metathorax trapezoidal, as long as wide. Aedeagus: Median lobe slender and simple ( Fig. 38g ). Phallobase of median lobe symmetrical and rounded ( Fig. 38g –h ). Parameres asymmetrical, left long, bent with divided apex ( Fig. 38g –h ).

Distribution. Northland ( Fig. 40 : star).

Habitat. The holotype of this species was collected by pyrethrin-fogging fungusy logs in hardwood and podocarp forests.
