D i a g n o s i s.Aspeciesofintermediatesize,pronotum and head unicolorous orange, elytra reddish brown, shiny, pronotum glabrous, densely punctured, as wide as base of elytra, elytra with very short adherent setae, more dense on apical part, with punctures in rows and interstices punctured and with transverse wrinkles.

T y p e l o c a l i t y. Nouvelle-Calédonie, Yaté, Rivière bleue, S 22°10, E 166°51.

D e s c r i p t i o n o f h o l o t y p e (male) ( Figs 9, 10 View Figs 1-13 , 30 View Figs 24-32 )

H a b i t u s. Orange-brown, elytra reddish brown, shiny, pronotum glabrous, densely punctured, elytra with very short adherent setae, with punctures in rows and interstices punctured and with transverse wrinkles, body of intermediate size, shape cylindrical, widest at humerus and attenuate towards apex of elytra and pronotum, pronotum as wide as base of elytra; size [mm]: length 3.85, width of elytra at humeri 2.65, length of elytra 2.65; length of pronotum 1.45, maximum width 2.65.

H e a d. Moderately large, sunk into thorax up to hind margin of eyes, orange-brown, puncturation rugulose, with a very shallow longitudinal depression at middle, almost round and relatively small, eyes distant, distance between upper lobes of eyes 1.58 times eye length; antennae inserted above lower margin of eyes, antennae orange-brown, antennomeres 7 to 11 darkened and expanded; clypeus with transverse wrinkles, broad, apically with a pair of lobes; labrum transverse, narrow; mandible with dark brown tip, with two large teeth ( Fig. 30 View Figs 24-32 ).

T h o r a x. Prothorax: pronotum evenly curved at sides and strongly attenuate towards apex from basal 1/5 onwards, pronotum broadest at base, without impressions; lateral margins even, carinate, getting more explanate towards base, simultaneously visible in dorsal view in hind edges only, hind angles acute, tooth-like; pronotum with puncturation dense, partly punctures fused but not forming regular furrows, prothorax almost quadrate ( Fig. 58 View Figs 53-58 ), lateral margins simple, front margin slightly convex and bend downwards, hind margin slightly concave; mesothorax: scutellum smooth, brown; elytra basally broadest then gradually attenuate, punctures small and in nine regular rows plus scutellar row and row abutting lateral margin of elytra, punctures in furrows, all striae with very short white adhesive setae, interstices convex except for plain base of elytra, with micropunctures and irregular transverse wrinkles; metathorax: legs orange-brown, claws black, appendiculate, fore tibiae straight.

A b d o m e n.Sternitesandtergitesorange-brown,withshortwhitesetae,sterniteVII without fovea, sternite III as long as sternites IV to VII along midline, pygidium without longitudinal median carina, only slightly bulging centrally; aedeagus ( Figs 9, 10 View Figs 1-13 ), length of the aedeagus: 1.0 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; clypeus with a pair of lobes as in male, but lobes slightly shorter; pygidium as in male; size

[mm]: length 3.85, width of elytra at humeri 2.65, length of elytra 2.6; length of pronotum 1.3, maximum width 2.6.

V a r i a b i l i t y. No variability in external morphology was detected, variability in size [mm] (mean±SD (max., min., n)): length of male 3.77±0.08 (3.85, 3.70, 3), width of elytra at humeri 2.62±0.03 (2.65, 3.60), length of pronotum 1.43±0.03 (1.45, 1.40) and width 2.58±0.06 (2.65, 2.55).

D i f f e r e n t i a l d i a g n o s i s.Differsfromtheotherspecieswithsetoseelytra and yellow tarsi, S. forcipatus (Baly) , by the regular rows of elytral punctures, the sparse short elytral setae, and the colouration of pronotum and head.

D i s t r i b u t i o n a n d b i o l o g y. Known from the South of New Caledonia mainland only.

E t y m o l o g y. Dedicated to its collector, the Chrysomelidae specialist Dr. Pierre Jolivet, Paris.
