D i a g n o s i s.Asmallspecieswithpronotum in lateral view plain, in one level with elytra, narrower than elytra at humerus, completely covered with very fine parallel longitudinal furrows, without punctures except for some small punctures on lateral carina and hardly visible punctures in front edges, elytra glabrous, punctures in regular rows.
T y p e l o c a l i t y. Nouvelle-Calédonie, Sarra, Col d’Amieu, S 21°34’, E 165°46’, 489 m.
D e s c r i p t i o n o f h o l o t y p e (female) ( Figs 22 View Figs 14-23 , 41 View Figs 33-43 )
H a b i t u s. Cinnamon brown, with clypeus, lateral and apical margins of pronotum, and interstice 10 of elytra yellow ( Fig. 62 View Figs 60-64 ), pronotum matt, in lateral view plain ( Fig. 22 View Figs 14-23 ), with very fine longitudinal furrows, elytra matt, body small, shape longitudinal oval, base of elytra wider than pronotum, size [mm]: length 2.7, width of elytra at humeri 1.6, length of elytra 0.95; length of pronotum 0.8, maximum width 1.5.
H e a d. Sunk into thorax up to hind margin of eyes, frons covered very densely with micropunctures, matt, with shallow longitudinal groove on frons, distance between upper lobes of eyes 1.85 times eye length; antennae inserted above level of lower margin of eyes, and distant from eye; antennae yellowish brown, segments 7-11 darker brown and extended; clypeus transverse, yellowish brown, covered with few short white setae, apical margin bearing a pair of short lobes with a long seta each; labrum transverse, arcuate at apex; mandible yellowish brown with dark brown tip.
T h o r a x. Prothorax: pronotum evenly curved at sides and constricted towards apex from basal 1/3 onwards, pronotum broadest at base, in lateral view, pronotum in one level with elytra, i.e. not vaulted; anterior margin narrowly, lateral margins broadly yellow, lateral margins even, carinate, completely visible in dorsal view, basal margin not notched opposite to humerus, hind edges triangularly extended; pronotum glabrous, with very fine longitudinal furrows, without punctures except for some small punctures on lateral carina and hardly visible punctures in front edges, prothorax almost quadrate ( Fig. 57 View Figs 53-58 ), with coarse punctures, lateral margins simple, front margin slightly concave and plain, hind margin slightly convex; mesothorax: scutellum with fine punctures, dark brown; elytra broadest at humerus, then parallel to apical 1/5, glabrous, with nine regular rows of distinct punctures, plus scutellar row of punctures and row abutting lateral margin of elytra, interstices convex with fine transverse wrinkles; metathorax: legs yellowish brown, claws appendiculate, fore tibiae straight.
A b d o m e n.Sternitesandtergitesyellowishbrown,sterniteIII distinctly shorter than sternites IV to VII along midline, pygidium evenly vaulted with short white setae; egg dimple large, eggs found during the dissections measured 0.5 X 0.3 mm, kotpresse with dorsal sclerites straight, apodemes wider than rectum, ventral sclerite with apodemes rounded; spermatheca narrow, hook-shaped ( Fig. 41 View Figs 33-43 ).
V a r i a b i l i t y Elytra lighter, i.e. yellowish-brown with blurred cinnamon-brown markings; variability in size of females [mm] (mean±SD (max., min., n)): length 2.47±0.15 (2.65, 2.25, 7), width of elytra at humeri 1.42±0.12 (1.55, 1.20), length of pronotum 0.80±0.06 (0.90, 0,70) and width 1.36±0.12 (1.50, 1.15).
D i f f e r e n t i a l d i a g n o s i s Differs from all other species of Scaphodius in the pronotum being in one level with the elytra, from S. montrouzieri nov.sp., a species of similar size, by the pronotum being narrower than the elytra at humerus.
D i s t r i b u t i o n a n d b i o l o g y. Known from central New Caledonia mainland only.
E t y m o l o g y. Complanatus means flattened out, in one plane, referring to the pronotum.
