Type species. Cerabilia maori Laporte de Castelnau, 1867 , by monotypy.

Description. Body length 6.1–11.4 mm; stout or slender. Color dark, rufous to black. Metallic luster absent. Dorsal surface shiny or dull, mostly glabrous. Head, pronotum, and elytra with dense micropores. Head. Rather small, compared to pronotum (very large in C. takaka ). Mandibles moderately long and curved. Labrum moderately transverse. Eyes small or moderately large, slightly or moderately convex. Tempora inflated or not. Antennae: segments 1–3 with a deep longitudinal furrow dorsally; segment 2 symmetrically inserted into segment 1 (scape). Frons smooth or wrinkled (with oblique strioles). Mentum: median tooth present, subrounded, subtruncate or subtriangular apically; lateral lobes acute apically, much shorter than median tooth. Palpi: terminal segment obtuse or truncate apically; maxillary and labial segments sparsely setulose. Thorax. Pronotum impunctate, moderately wide or very wide, subcordate, trapezoid, subquadrate or subrectangular; anterior bead incomplete, obsolete medially; a single setiferous puncture (anteriorly) or two setiferous punctures (anteriorly and posteriorly) on each side; laterobasal foveae single (outer foveae absent, inner foveae sulciform) or double (outer foveae present, inner foveae sulciform); pronotal base slightly to strongly emarginate, partly covering elytral base. Scutellum visible, with tip slightly or strongly projected behind elytral base. Prosternum wrinkled. Metepimera short, rounded apically. Legs. Moderately long. Metatrochanters about half as long as femora. Pro-, meso-, and metatibiae with an apical ctenidium (comb-like structure). Cleaning organ of protibiae with two setal clips. Metatibiae curved. Metatarsomeres 5 glabrous ventrally. Elytra. Oblong or subovate. Basal margin complete, reaching scutellum (incomplete, reaching base of stria 1 in C. takaka ). Shoulders well developed, obtuse. Scutellar setiferous pore absent (present at base of stria 2 in C. kaihoka , C. takaka , and C. willi ). Striae present (9 in number), consisting of impressed lines. Intervals depressed (slightly convex in C. cordata ; 9 in number); interval 3 without setiferous puncture (with a single medial puncture in C. kaihoka and C. takaka ). Preapical punctures present (2 in number). Umbilicate series with 12 to 16 setiferous punctures separated into two major groups (6(7)+6(8)), with or without 1 seta in between. Subapical sinuations present or absent. Apices obtuse or obtusely rounded. Sternum VII of male with or without dense coarse punctures medially. Aedeagus. Lateral view ( Fig. 8–19 ): moderately or strongly arcuate, wide or slender; base with or without lobe or bead; apex subtriangular, with extreme tip usually narrow, very long, and curved downward. Dorsal view: symmetrical (ostium of membranous area dorsal); apex usually rounded (rarely truncate, triangular or laterally hooked), usually straight (deflected to the left in C. aphela ). Right paramere larger, conchoid; left paramere slender, digitiform.
