H a b i t u s. Dark brown with yellowish markings on pronotum and elytra, pronotum shiny with longitudinal furrows ( Fig. 61 View Figs 60-64 ), elytra matt, basal four antennomeres yellowish brown, body small, shape cylindrical, truncate, male mandibles simple, pronotum wider as base of elytra, size [mm]: length 2.25, width of elytra at humeri 1.55, length of elytra 1.6; length of pronotum 0.85, maximum width 1.5.
H e a d. Sunk into thorax up to hind margin of eyes, dark brown with a pair of triangular yellow spots at level of upper margin of eyes, puncturation of frons dense and coarse, at base with longitudinal furrows, with shallow longitudinal groove on frons, distance between upper lobes of eyes 1.13 times eye length; antennae inserted slightly above level of lower margin of eyes, antennae yellowish brown with antennomeres 6–11 dark brown; clypeus triangular, yellow, with transverse furrows, glabrous, basal margin simple ( Fig. 25 View Figs 24-32 ); labrum transverse, slightly arcuate at apex, with long white setae surpassing apex; mandible simple, dark brown.
T h o r a x. Prothorax: pronotum evenly curved at sides and constricted towards apex from basal 1/5 onwards, pronotum broadest at base, in lateral view pronotum most vaulted at middle, dark brown with apical margin, hind angles and a pair of longitudinal markings at base yellowish brown, lateral margins even, carinate, not visible in dorsal view, basal margin with a triangular notch opposite to each humerus, hind edges acute, tooth-like, pronotum glabrous, completely covered with longitudinal furrows, without punctures, opposite to scutellum semicircular furrows, prothorax densely covered with very coarse punctures, lateral carina simple, front margin slightly concave, bend downwards, hind margin concave; mesothorax: scutellum smooth, dark brown; elytra basally broadest then gradually attenuate, glabrous, with nine regular rows of distinct punctures, plus scutellar row of punctures and row abutting lateral margin of elytra, interstices convex with transverse wrinkles; metathorax: legs yellowish brown with femur and tibia partly dark brown, first tarsomeres of fore- and mid tarsus widened, claws appendiculate, fore tibiae straight.
A b d o m e n.Sternitesdarkbrown,withshortwhitesetae,sterniteVIIwithadistinct fovea, tergites light brown, pygidium yellowish brown with a bulging yellow longitudinal carina and apical margin bulging yellow, sternite III longer than sternites IV to VII along midline; aedeagus ( Figs 3, 4 View Figs 1-13 ), length of the aedeagus: 0.9 mm.
D e s c r i p t i o n o f f e m a l e. In female distance between upper lobes of eyes 1.36 times eye length, dorsum and venter coloured as in male; mandibles, clypeus and labrum simple; egg dimple broad and shallow; spermathecal duct very long, straight and densely coiled up ball-like close to spermatheca, spermatheca hook-shaped, as long as wide, receptacle little wider than pump only ( Fig. 40 View Figs 33-43 ).
V a r i a b i l i t y Sometimes basal margin of pronotum broadly yellowish brown. Variability in size [mm] (mean±SD (max., min., n)): length of male 2.35±0.13 (2.50, 2.25, 3), female 2.66±0.09 (2.80, 2.60, 4), width of elytra at humeri in male 1.53±0.03 (1.55, 1.50), female 1.71±0.10 (1.80, 1.60), length of pronotum in male 0.80±0.05 (0.85, 0.75), width 1.52±0.03 (1.55, 1.50), length of pronotum in female 0.89±0.03 (0.90, 0.85) and width 1.70±0.12 (1.80, 1.55); distance between upper lobes of eyes in male 1.069 (1.066, 1.071) times eye length, in female 1.356 (1.266, 1.448) times eye length.
D i f f e r e n t i a l d i a g n o s i s Differs from the similar species S. striaticollis (MONTROUZIER) by the concave hind margin of prothorax and the less distant eyes.
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. Dedicated to Xavier MONTROUZIER (1820-1897), who described the first species of Scaphodius and many more insects from New Caledonia in the 19 th Century.
