( Figs. 3e , 4e , 5 )

Type Material. Holotype. NEW ZEALAND: Northland: 1♂ ( NZAC), aedeagus dissected and mounted in balsam on a clear plastic card, “New Zealand: ND: Omahuta S.F., Kauri Res., litter 74/81 10 Oct 1974, JC Watt”, “ HOLOTYPE Sagola northlandensis Park and Carlton 2013 ”.

Etymology. The species name is based on the biotic region of the type locality, Northland.

Diagnosis. This species can be distinguished from the other species of the hirtalis group by the following combination of characters: antennomere 1 elongate, approximately 3 times longer than wide; antennomere 4 elongate; posterior frontal fovea elongate; eye small, one-third length of temple; hind wings well-developed; shape of genitalia unique to species.

Description of Male. Length 3.0 mm. Body brown and elytra, legs, maxillary palpi yellowish brown ( Fig. 3e ). Head: As long as wide, widest across eyes ( Fig. 3e ). Antennomere 1 approximately 3 times longer than wide, 2–3 longer than wide, 4 elongate, approximately 1.5 times longer than wide, 5 longer than wide, 6–10 subquadrate. Frontal sulcus deep and reaching behind eye from end of frontal rostral lobes. Anterior frontal fovea round, posterior frontal fovea elongate. Eye small and prominent, one-third length of temple. Thorax: Prosternum as long as wide, widest at one-third length. Elytra rectangular ( Fig. 3e ). Hind wings well-developed. Meso- and metathorax trapezoidal, longer than wide. Abdomen: Tergite IV with pair of transverse patches of microtrichia reaching middle. Aedeagus: Median lobe longer than parameres with semicircular apical lobe ( Fig. 4e ). Phallobase of median lobe asymmetrical and triangular ( Fig. 4e ). Right paramere divided into 2 branches from base, and minor branch divided into 2 long branches ( Fig. 4e ).

Distribution. Northland ( Fig. 5 : white circle).

Habitat. The holotype and only known specimen of this species was collected by sifting litter.
