Etymology. This species is named after the type locality, Chatham Islands.

Diagnosis. This species can be distinguished from the other species of the auripila speciesgroup by the following combination of characters: body smaller, length 1.8–2.0 mm; ventral surface of head weakly convex; eye small, approximately one-third length of temple; frontal sulcus deep and linear, almost reaching vertexal fovea; anterior frontal fovea round and covered by frontal rostrum; posterior frontal fovea elongate; shape of antennomeres and genitalia unique to species.

Description. Length 1.8–2.0 mm. Body brown, antennae, maxillary palpi, elytra, and legs paler ( Fig. 37c View Fig ). Head: Male head as long as wide, widest across eyes ( Fig. 38k View Fig ), ventral surface of head weakly convex. Antennomere 1 approximately 1.5 times longer than wide, 2 longer than wide, 3–7 subquadrate, 8–10 weakly transverse. Frontal sulcus deep and linear, reaching almost vertexal fovea. Anterior frontal fovea round and covered by frontal rostrum, posterior frontal fovea elongate. Eye small, approximately onethird length of temple. Thorax: Prosternum as long as wide, widest at one-third length. Elytra approximately triangular ( Fig. 37c View Fig ). Meso- and metathorax trapezoidal, longer than wide. Aedeagus: Median lobe bent S-shaped ( Fig. 38c View Fig ). Phallobase of median lobe symmetrical and rectangular ( Fig. 38c View Fig ). Parameres symmetrical and weakly curved with 1 seta apically and 3 setae on middle ( Fig. 38c View Fig ).

Distribution. Chatham Islands ( Fig. 39 View Fig : black square).

Habitat. Specimens of this species were collected using pitfall traps or by sifting forest litter in a coastal area.
