Etymology. This species is named for the collector of the holotype, Clare F. Butcher.

Diagnosis. This species can be distinguished from the other species of the baiknami speciesgroup by the following combination of characters: smaller body, length 2.3–2.8 mm; male head bluntly triangular, widest across temples, ventral temporal lobe flat; male mid-femur weakly depressed at base and mid-tibia bent; shape of antennomeres and genitalia unique to species.

Description of Male. L e n g t h 2.3– 2.8 m m. Body brown, antenna, elytra, legs, and maxillary palpi paler ( Fig. 15c ). Head: Bluntly triangular, widest across temples, ventral temporal lobe flat ( Fig. 15c ). Antennomere 1 approximately 2 times longer than wide, 2–7 subquadrate, 8–10 weakly transverse. Frontal sulcus deep and reaching midpoint of eye from frontal rostral lobes. Anterior frontal fovea round. Posterior frontal fovea elongate. Eye large and prominent, one-third length of temple. Thorax: Prosternum as long as wide, widest at midpoint. Elytra rectangular ( Fig. 15c ). Meso- and metathorax trapezoidal, longer than wide. Male mid-femur weakly depressed at base. Male mid-tibia bent. Abdomen: Tergite IV with pair of oval or transverse patches of microtrichia. Aedeagus: Median lobe blunt ( Fig. 16c ). Phallobase of median lobe asymmetrical and triangular ( Fig. 16c ). Parameres asymmetrical, left paramere L-shaped, right paramere with thick setae apically ( Fig. 16c ).

Distribution. Gisborne, Taupo ( Fig. 17 : black squares).
