Etymology. This species is named for one of the enthusiastic supporters of this study, James H. Boone. He assisted with specimen access through loans and during the first author’ s visit to the Field Museum of Natural History, Chicago, IL.

Diagnosis. This species can be distinguished from the other species of the insignis speciesgroup by the following combination of characters: body length 2.7–3.0 mm; temporal lobe of male head distinctly projecting, exceeding eye, with concave 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.

Description. Length 2.7–3.0 mm. Body brown, antennae, legs, maxillary palpi, and elytra paler ( Fig. 68v ). Head: Male head triangular, widest across temples ( Fig. 69v ). Female head bluntly triangular, widest across eyes. Antennomere 1 approximately 1.5 times longer than wide, 2–8 longer than wide, 9–10 subquadrate. Frontal sulcus deep, reaching midpoint of eye. Anterior frontal fovea round, partially covered by frontal rostrum, posterior frontal fovea oval. Eye prominent, approximately one-third length of temple. Temporal lobe of male head distinctly projecting, exceeding eye, with concave ventral surface ( Fig. 69v ). Ventral surface of male head with transverse process behind mouthparts and round depression bearing 3 patches of dense setae ( Fig. 69v ). Thorax: Prosternum as long as wide, widest at one-third length. Elytra subquadrate ( Fig. 68v ). Meso- and metathorax trapezoidal, as long as wide. Abdomen: Male tergite IV with pair of small round patches of microtrichia, patches absent in female. Aedeagus: Median lobe of genitalia broad and rectangular ( Fig. 70v ). Phallobase of median lobe symmetrical and rounded ( Fig. 70v ). Parameres symmetrical and slender, sparsely setose from apical two-thirds to apex ( Fig. 70v ).

Distribution. Taranaki, Taupo, Waikato ( Fig. 74 : stars).

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