Etymology. This species is named for one of the enthusiastic supporters of this study, Roger G. Booth. He assisted with type examinations and access to specimens during the first author’ s visit to the Natural History Museum, London.

Diagnosis. This species can be distinguished from the other species of the major species-group by the following combination of characters: body length 1.8–2.0 mm; eye large, two-thirds length of temple; ventral temple of male head with depressed and projecting temporal lobe, surface concave; shape of antennomeres and genitalia unique to species; only known from Auckland.

Description. Length 1.8–2.0 mm. Body brown, antennae, legs, maxillary palpi, and elytra paler ( Fig. 66d ). Head: Male head triangular, widest across temples ( Fig. 66d ). Female head bluntly triangular, widest across eyes. Ventral temple of male head with depressed and projecting temporal lobe and surface concave ( Fig. 66r ). Thick, dense setae on male gular depression. Antennomere 1 approximately 1.5 times longer than wide, 2 longer than wide, 3 subquadrate, 4 longer than wide, 5–10 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. 66d ). Meso- and metathorax trapezoidal, longer than wide. Abdomen: Tergite IV with pair of transverse patches of microtrichia reaching middle, patches absent in female. Aedeagus: Median lobe of genitalia broader apically with long process dorsally and membranous tube extending from apex ( Fig. 66j ). Phallobase of median lobe symmetrical and rounded ( Fig. 66j ). Parameres symmetrical, broader than median lobe, setose from midpoints to apices ( Fig. 66j ).

Distribution. Auckland ( Fig. 67 : star).

Habitat. Specimens of this species were collected using yellow pan and Malaise traps or by sifting rotten wood.
