Etymology. This species is named for one of the enthusiastic supporters of this study, Bonnie Boudreaux. She was a member of the first author’ s PhD advisory committee and provided valuable advice during this study, a major component of his dissertation.

Diagnosis. This species can be distinguished from the other species of the insignis speciesgroup by the following combination of characters: body length 2.3–2.6 mm; temporal lobe of male head projecting, slightly exceeding eye and with weakly concave ventral surface; ventral surface of male head with triangular setose process behind mouthparts; elytra subquadrate; shape of antennomeres and genitalia unique to species; known from Bay of Plenty.

Description. Length 2.3–2.6 mm. Body brown, antennae, legs, maxillary palpi, and elytra paler ( Fig. 68q ). Head: Male head triangular, widest across temples ( Fig. 69q ). Female head bluntly triangular, widest across eyes. Antennomere 1 approximately 1.5 times longer than wide, 2 longer than wide, 3 subquadrate, 4–6 longer than wide, 7–10 subquadrate. Frontal sulcus deep, reaching midpoint of eye. Anterior frontal fovea round, partially covered by frontal rostrum, posterior frontal fovea round. Eye large and prominent, approximately one-third length of temple. Temporal lobe of male head projecting, slightly exceeding eye, with weakly concave ventral surface ( Fig. 69q ). Ventral surface of male head with triangular setose process behind mouthparts ( Fig. 69q ). Thorax: Prosternum as long as wide, widest at one-third length. Elytra subquadrate ( Fig. 68q ). Meso- and metathorax trapezoidal, as long as wide. Abdomen: Male tergite IV with pair of transverse patches of microtrichia reaching middle, patches absent in female. Aedeagus: Median lobe of genitalia broad, with pair of small triangular processes apically, apical lobe with flat margin ( Fig. 70q ). Phallobase of median lobe symmetrical and rounded ( Fig. 70q ). Parameres symmetrical and slender, sparsely setose from midpoints to apices ( Fig. 70q ).

Distribution. Bay of Plenty ( Fig. 73 : white circle).

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