NEW ZEALAND: Marlborough Sounds : 5♂♂ 4♀♀ ( LUNZ), same data as holotype ; 1♀ ( LUNZ), Middle Trio Island , 15 II 1995, J.W.M. Marris, LUNZ 95 /6 litter ex Melicytus / broadleaf forest .

Etymology. This species is named for one of the enthusiastic supporters of this study, JeongNam Lee. She is one of the first author’ s colleagues and assisted with molecular components of the phylogenetic analysis.

Diagnosis. This species can be distinguished from the other species of the insignis speciesgroup by the following combination of characters: body length 2.4–2.7 mm; temporal lobe of male head distinctly projecting, exceeding eye, with C-shaped ventral surface; ventral surface of male head with transverse process behind mouthparts and round depression bearing three patches of dense setae; elytra subquadrate; shape of antennomeres and genitalia unique to species; only known from Marlborough Sounds.

Description. Length 2.4–2.7 mm. Body brown, antennae, legs, maxillary palpi, and elytra paler ( Fig. 68x ). Head: Male head triangular, widest across temples ( Fig. 69x ). Female head bluntly triangular, widest across eyes. Antennomere 1 approximately 1.5 times longer than wide, 2–3 subquadrate. 4–6 longer than wide, 7–10 subquadrate. Frontal sulcus deep, reaching midpoint of eye. Anterior frontal fovea round and partially covered by frontal rostrum, posterior frontal fovea oval. Eye large and prominent, approximately onethird length of temple. Temporal lobe of male head distinctly projecting, exceeding eye, with C-shaped ventral surface ( Fig. 69x ). Ventral surface of male head with transverse process behind mouthparts and round depression bearing 3 patches of dense setae ( Fig. 69x ). Thorax: Prosternum as long as wide, widest at one-third length. Elytra subquadrate ( Fig. 68x ). Meso- and metathorax trapezoidal, as long as wide. Abdomen: Male tergite IV without patch of microtrichia. Aedeagus: Median lobe of genitalia broad, with bluntly triangular apical lobe ( Fig. 70x ). Phallobase of median lobe symmetrical and rounded ( Fig. 70x ). Parameres symmetrical and slender, with setae at apex and midpoint ( Fig. 70x ).

Distribution. Marlborough Sounds ( Fig. 74 : white squares).

Habitat. Specimens of this species were collected using pitfall traps in forsts of Melicytus J. R. Forst. & G. Forst. (Violaceae) , Myoporum Sol. ex G. Forst. (Scrophulariaceae) , and Rhopalostylis Klotzsch ex Baill. (Euphorbiaceae) ; one was taken by sifting leaf litter in Melicytus /broadleaf forests.
