Fig. 50–52 , 93–95 , 151–153

Type species. Colpodes crenatus Chaudoir, 1878 , by present designation.

Description. Body length 12.8–20.2 mm. Color mostly dark. Metallic luster absent. Dorsal surface mostly glabrous. Forebody very wide in comparison to elytra. Head. Moderately wide or very wide. Mandibles moderately long or very long. Labrum subtruncate or emarginate anteriorly. Eyes moderately convex, separated from buccal fissures; a single setiferous puncture on inner side of each eye (posteriorly). Tempora inflated or not. Neck constriction deep dorsolaterally. Mentum tooth entire, acute apically; two small circular foveae; two long setae. Submentum with two, four, or six long setae. Palpi with terminal segment truncate apically. Ligula with two setae. Paraglossae glabrous. Thorax. Pronotum cordate or suborbicular; a single setiferous puncture on each side (anteriorly). Prosternum glabrous or pubescent apically, not compressed into a vertical ridge. Legs. Moderately long or very long. Metacoxae with three or four posteroventral setae. Metafemora with two to four posteroventral setae. Protibiae with dorsal longitudinal groove; cleaning organ with three clip setae. Meso- and metatarsomeres 1–4 poorly or well developed, tricarinate or not carinate dorsally, shallowly or deeply bisulcate laterally. Metatarsomeres 4 moderately bilobed, moderately or strongly asymmetrical apically. Metatarsomeres 5 glabrous ventrally. Elytra. Oblong, ovate, or subovate. Fused along suture (hindwings vestigial). Basal margin complete (reaching about scutellum) or incomplete (reaching about stria 1). Shoulders narrow, rounded or obtuse. Sides widest about middle. Scutellar setiferous pore visible or not. Scutellar striole short. Striae complete, consisting of impressed lines. Interval 3 without setiferous punctures. Umbilicate series with 17–25 setiferous punctures. Apices rounded or mucronate. Abdomen. Sterna IV–VI: both sexes with two long apical ambulatory setae. Sternum VII (last visible sternum): male with two long apical ambulatory setae; female with four or six long apical ambulatory setae. Aedeagus. Lateral view: strongly arcuate, semicircular; basal lobe of basal bulb present; internal sac with or without scale-like sclerites. Dorsal view: moderately wide, symmetrical (ostium of membranous area dorsal) or asymmetrical (ostium of membranous area deflected to the left); basal bulb close to membranous area.

Remarks. The generic name is derived from Kupe (the legendary Polynesian navigator to whom is attributed the discovery of New Zealand) and Platynus (the type genus of the tribe Platynini ), genus masculine. The morphological characters unifying species of Kupeplatynus are: forebody wide in comparison to elytra; a single setiferous puncture on inner side of each eye (posteriorly); mentum tooth entire, acute apically; metatarsomeres 4 asymmetrical apically; interval 3 of elytra without setiferous punctures; abdominal sterna IV–VI of both sexes with two long apical ambulatory setae; aedeagus (in lateral view) strongly arcuate, semicircular. Kupeplatynus species occur in northern areas of the North Island. See also Remarks under Kiwiplatynus .
