Exocelina kakapupu

Size and shape: Beetle small (TL-H 3.15–3.4 mm, TL 3.55–3.8 mm, MW 1.7–1.85 mm), with oblong-oval habitus, broadest at elytral middle. Coloration: as in Exocelina soppi sp. n. and Exocelina pseudosoppi sp. n (Fig. 48). Surface sculpture: Punctation as in Exocelina soppi sp. n. and Exocelina pseudosoppi sp. n. but denser and coarser; microreticulation evidently stronger than in these species. Structures: Pronotum without lateral bead or with weak traces of lateral bead. Base of prosternum and neck of prosternal process with distinct ridge, anteriorly rounded, smooth, with very small anterolateral extensions. Blade of prosternal process lanceolate, relatively broad, slightly convex, with distinct bead and few setae; neck and blade of prosternal process evenly jointed. Abdominal sternite 7 broadly truncate apically. Male: Antenna simple (Fig. 22A). Protarsomere 4 with large, thick, strongly curved anterolateral hook. Protarsomere 5 ventrally with anterior row of 13 short setae and posterior row of 3 short setae (Fig. 22B). Abdominal sternite 7 with 2–7 lateral striae on each side. Median lobe with strong submedian constriction in ventral view and almost truncate apex in lateral view (Figs 22C, D). Paramere with notch on dorsal side and elongate subdistal part, with numerous, dense, long, thin setae; setae of proximal part longer, thicker, distinctly visible (Fig. 22E). Female: Without evident differences in external morphology from male, except for abdominal sternite 7 without striae.
