Etymology. This species is named for one of the enthusiastic supporters of this study, Baik-Nam Park. He is the first author’ s father and has provided a lifetime of support and encouragement.

Diagnosis. This species can be distinguished from the other species of the baiknami speciesgroup by the following combination of characters: larger body, length 2.9–3.1 mm; antennomeres 4–10 with tubercles; triangular head with flat ventral temporal lobe; shape of antennomeres and genitalia unique to species.

Description. Length 2.9–3.1 mm. Body brown, antennae, legs, maxillary palpi, and elytra paler (Fig. 15a). Head: Male head triangular, widest across temples (Fig. 15a), temple lobed and flat ventrally. Female head rectangular, widest across eyes. Antennomere 1 approximately 2 times longer than wide, 2 longer than wide, 3 subquadrate, 4 elongate, 5–10 subquadrate, 4–10 with tubercles. Frontal sulcus reaching midpoint of eye from frontal fovea. Anterior frontal fovea round. Posterior frontal fovea round. Eye small and prominent, one-third length of temple in male, one-fourth length of temple in female. Thorax: Prosternum as long as wide, widest at midpoint. Elytra rectangular (Fig. 15a). Meso- and metathorax trapezoidal, longer than wide. Hind wings well-developed. Abdomen: Tergite IV with pair of transverse patches of microtrichia reaching middle. Aedeagus: Median lobe longer than parameres, S-shaped (Fig. 16a). Phallobase of median lobe symmetrical and rectangular (Fig. 16a). Parameres asymmetrical, right paramere elongate (Fig. 16a).

Distribution. Northland (Fig. 17: black circles).

Habitat. Most specimens of this species were collected using window and flight intercept traps or by sifting leaf and log litter in kauri, broadleaf, hardwood, and podocarp forests.
