D e s c r i p t i o n o f h o l o t y p e (male)(Figs5,6,21,27)

H a b i t u s. Yellowish brown with irregular darker brown markings on interstices of elytra, head, pronotum and elytra matt, body small, shape cylindrical, truncate ( Fig. 60 View Figs 60-64 ), pronotum as wide as base of elytra, pronotum with fine longitudinal furrows and additionally punctured, elytra glabrous with punctures in regular rows; size [mm]: length 2.15, width of elytra at humeri 1.3, length of elytra 1.45; length of pronotum 0.8, maximum width 1.3.

H e a d. Sunk into thorax up to hind margin of eyes, puncturation very dense and coarse, in-between microsculptured, matt, with shallow longitudinal groove on frons, eyes distant, distance between upper lobes of eyes 1.95 times eye length; antennae inserted above level of lower margin of eyes, antennae yellowish brown, antennomeres 7- 11 darker and widened; clypeus short, light brown, glabrous, basal margin slightly convex with a pair of lateral longitudinal hollowed extensions; labrum transverse, convex at apex; mandible large, yellowish brown with dark brown tip ( Fig. 27 View Figs 24-32 ).

T h o r a x. Prothorax: in lateral view, pronotum most vaulted near apical margin ( Fig. 21 View Figs 14-23 ), pronotum evenly curved at sides and constricted towards apex from basal 1/2 onwards, pronotum broadest at base; yellowish brown, a pair of blurred spots darker brown, lateral margins even, carinate, in dorsal view hind edges visible only, hind edges acute, tooth-like; pronotum glabrous, covered completely with both narrow longitudinal furrows and dense punctures, the latter more dense near lateral margin, prothorax densely covered with coarse punctures, with apical margin straight, prothorax densely covered with very coarse punctures, with front margin straight, lateral carina simple, narrow, hind margin straight; 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, matt; metathorax: legs yellowish brown, claws appendiculate, fore tibiae slightly bend, first tarsomeres of fore tarsi slightly widened.

A b d o m e n. Sternites, tergites and pygidium yellowish brown, with short white setae, sternite VII with a very shallow fovea, sternite III as long as sternites IV to VII along midline; aedeagus ( Figs 5, 6 View Figs 1-13 ), length of the aedeagus: 0.8 mm.

D e s c r i p t i o n o f f e m a l e. Dorsum and venter coloured as in male;

pygidium with a very short longitudinal ridge at middle at apex; mandibles, clypeus and labrum simple; egg dimple broad and deep.

V a r i a b i l i t y. Body darker brown than holotype, sometimes elytra with blurred brown markings. Variability in size [mm] (mean±SD (max., min., n)): length of male 2.21±0.04 (2.25, 2.15, 5), female 2.57±0.03 (2.60, 2.55, 5), width of elytra at humeri in male 1.32±0.03 (1.35, 1.30), female 1.57±0.03 (1.60, 1.55), length of pronotum in male 0.79±0.02 (0.80, 0.75), width 1.32±0.03 (1.35, 1.30), length of pronotum in female 0.87±0.03 (0.90, 0,85) and width 1.53±0.03 (1.55, 1.50).

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) , S. complanatus nov.sp., and S. montrouzieri nov.sp. by the many punctures in-between the parallel longitudinal furrows of the pronotum.

D i s t r i b u t i o n a n d b i o l o g y. Known from type locality only, collected by beating from Terminalia cherrieri (Combretaceae) . This tree is endemic to New Caledonia and threatened by habitat loss.

E t y m o l o g y. Dedicated to Eduard SUFFRIAN (1805-1876), who wrote the major revisions on Cryptocephalinae and proposed the genus Scaphodius in litteris.
