Etymology. This species is named after the type locality, Cuvier Island, Coromandel.

Diagnosis. This species can be distinguished from the other species of the insignis species-group by the following combination of characters: body length 2.4–2.6 mm; temporal lobe of male head distinctly projecting, exceeding eye, with weakly concave ventral surface; ventral surface of male head with blunt process behind mouthparts and round setose depression; male elytra rectangular, female elytra subquadrate; shape of antennomeres and genitalia unique to species; known only from Coromandel.

Description. Length 2.4–2.6 mm. Body brown, antennae, legs, maxillary palpi, and elytra paler ( Fig. 68m ). Head: Male head triangular, widest across temples ( Fig. 69m ). Female head bluntly triangular, widest across eyes. Antennomere 1 approximately 1.5 times longer than wide, 2–7 longer than wide, 8–10 subquadrate. Frontal sulcus deep, reaching end of eye. Anterior frontal fovea round, partially covered by frontal rostrum, posterior frontal fovea round. Eye prominent, approximately one-third length of temple. Temporal lobe of male head distinctly projecting, exceeding eye and with weakly concave ventral surface ( Fig. 69m ). Ventral surface of male head with blunt process behind mouthparts and round setose depression ( Fig. 69m ). Thorax: Prosternum as long as wide, widest at one-third length. Male elytra rectangular ( Fig. 68m ), female elytra subquadrate. Male meso- and metathorax trapezoidal, longer than wide, female 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 processes apically, reaching apex of apical lobe ( Fig. 70m ). Phallobase of median lobe symmetrical and rounded ( Fig. 70m ). Parameres symmetrical and slender, sparsely setose from midpoints to apices ( Fig. 70m ).

Distribution. Coromandel ( Fig. 73 : black circle).

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