Etymology. This species is named for one of the enthusiastic supporters of this study, Dorothy Prowell. 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 major species-group by the following combination of characters: body small, length 1.5–1.7 mm; eye large and prominent, two-thirds length of temple; ventral temple of male head with depressed and distinctly projecting temporal lobe, surface concave; shape of antennomeres and genitalia unique to species; only known from Wellington.

Description. Length 1.5–1.7 mm. Body brown, antennae, legs, maxillary palpi, and elytra paler ( Fig. 66e ). Head: Male head triangular, widest across temples ( Fig. 66e ). Female head bluntly triangular, widest across eyes. Ventral temple of male head with depressed and distinctly projecting temporal lobe, surface concave ( Fig. 66s ). Thick, dense setae on male gular depression. Antennomere 1 approximately 2 times longer than wide with dull surface, 2 longer than wide, 3–10 subquadrate. Frontal sulcus shallow, reaching midpoint of eye. Anterior frontal fovea oval, partially covered by frontal rostrum, posterior frontal fovea oval. Eye large and prominent, two-thirds length of temple. Thorax: Prosternum as long as wide, widest at one-third length. Elytra rectangular ( Fig. 66e ). Meso- and metathorax trapezoidal, longer than wide. Abdomen: Tergite IV with pair of transverse patches of microtrichia reaching middle. Aedeagus: Median lobe of genitalia broader apically with tube extending from apex ( Fig. 66k ). Phallobase of median lobe symmetrical and rounded ( Fig. 66k ). Parameres symmetrical and narrow, with process at midpoint, setose from midpoints to apices ( Fig. 66k ).

Distribution. Wellington ( Fig. 67 : white circle).

Habitat. Unknown.
