Etymology. This species is named after the type locality, Mercury Island, Coromandel.
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 distinctly projecting, exceeding eye, with flattened 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; only known from Coromandel of North Island.
Description. Length 2.3–2.6 mm. Body brown, antennae, legs, maxillary palpi, and elytra paler (Fig. 68l). Head: Male head triangular, widest across temples (Fig. 69l). Female head bluntly triangular, widest across eyes. Antennomere 1 approximately 1.5 times longer than wide, 2–3 subquadrate, 4–5 longer than wide, 6–10 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-half length of temple. Temporal lobe of male head distinctly projecting, exceeding eye, with flattened ventral surface (Fig. 69l). Ventral surface of male head with transverse process behind mouthparts and round depression bearing 3 patches of dense setae (Fig. 69l). Thorax: Prosternum as long as wide, widest at one-third length. Elytra subquadrate (Fig. 68l). 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 rectangular (Fig. 70l). Phallobase of median lobe symmetrical and rounded (Fig. 70l). Parameres symmetrical and slender with setae at apex and 1seta at midpoint (Fig. 70l).
