Sagola southlandensis Park and Carlton , new species

( Figs. 58k , 59l , 63 )

Type Material. Holotype. NEW ZEALAND: Southland: 1♂ ( NZAC), aedeagus dissected and mounted in balsam on a clear plastic card, “New Zealand SL Croyden Bush Gore 5-Sep-04”, “Forest floor litter from area subject to flooding”, “76.03 Southland Hills Hokonui”, “ HOLOTYPE Sagola southlandensis Park and Carlton 2013 ”. Original label does not mention who collected the type specimen, but it was collected by J. Nunn. Paratype (1 male). NEW ZEALAND: Southland : 1♀ ( JTN), same data as holotype .

Etymology. The species name is based on the biotic region of the type material, Southland.

Diagnosis. This species can be distinguished from the other species of the misella speciesgroup by the following combination of characters: larger body, length 2.7–2.8 mm; male antennomeres 4–10 enlarged; eye larger, approximately one-half length of temple; shape of antennomeres and genitalia unique to species; only known from Southland.

Description of Male. Length 2.7–2.8 mm. Body brown, antennae, legs, maxillary palpi, and elytra paler ( Fig. 58k ). Head: Round, as long as wide, widest across eyes ( Fig. 58k ). Antennomere 1 approximately 1.5 times longer than wide, 2–10 subquadrate, 4–10 enlarged, 6–11 with tubercles. Frontal rostrum rectangular, lobes continuous. Frontal sulcus reaching midpoint of eye. Posterior frontal fovea elongate. Eye prominent, approximately one-half length of temple. Thorax: Prosternum as long as wide, widest at midpoint. Elytra rectangular ( Fig. 58k ). Meso- and metathorax trapezoidal, longer than wide. Abdomen: Male tergite IV without pair of patches of microtrichia. Aedeagus: Median lobe of genitalia triangular, curved as S-shaped vertically ( Fig. 59l ). Phallobase of median lobe symmetrical and rounded ( Fig. 59l ). Parameres asymmetrical, right longer than left, with setae apically ( Fig. 59l ).

Distribution. Southland ( Fig. 63 : black square).

Habitat. Specimens of this species were collected by sifting forest litter.
