Head, pronotum, scutellum and elytra dark reddish brown with strong dark greenish metallic reflections, less intense on head; ventral surfaces dark reddish brown, darker and with hint of metallic luster on meso- and metathoracic ventrites and episterna; labrum, palpi, antennae and legs yellowish orange (Fig. 1e). Length: 2.67 mm (range: 2.48–3.10 mm); width: 1.38 mm (range: 1.20–1.61 mm).
Head hypognathous at rest; frons and vertex regularly convex, finely microsculptured, densely, deeply punctured, except medially on frons, sulcate above eyes with sulcus impressed, also punctured above transverse supra-antennal swellings, nearly touching at middle; glabrous except for long seta at middle of supraocular furrow and sparse short, fine appressed whitish setae on short genae. Clypeus nearly as long as wide at apex, punctured at base with smaller punctation than frons. Labrum small, smooth, about 1.5x as wide as long, weakly emarginate at apex. Last maxillary palpomere elongate, gradually narrowing at apical half toward blunt apex. Eyes large, bulging, entire. Antennae slender, reaching beyond middle of elytra; scape nearly cylindrical, slightly bent posteriorly, twice as long as thick, strongly narrowed at base; pedicel short, nearly spherical, less than half as long as scape; antennomeres 3–10 elongate, club-shaped, 3–6 glossy with sparse golden setae, 7–11 slightly incrassate, finely granulose, clothed with dense, short, fine hairs; antennomeres 3–4 subequal, longer than pedicel; fifth antennomere longer than fourth and sixth, and slightly shorter than seventh; antennomeres 8–10 subequal, as long as sixth; eleventh antennomere longest, pointed, obliquely cut at apex internally. Pronotum transverse (1.45x as wide at base than long at middle), convex with stronger declivity toward anterior angles; anterior border straight, produced forward medially, with very fine margin near anterior angles, narrower than posterior border, weakly bisinuate, with very short median lobe before scutellum, finely margined; anterior angles obtuse, slightly produced forward, with trichobothria displaced towards anterior border bearing long anterior setae; posterior angles obtuse, with trichobothria at angle and long obliquely, posteriorly and dorsally bent golden setae; sides more or less regularly curved, widest at middle, with narrow explanate margin; surface glabrous, shiny, very finely microsculptured, slightly irregular, with dense, deep, slightly elongate punctures, larger than distance separating them and sometimes confluent, forming irregular strigose areas on disc. Hypomera smooth, very finely shagreened, with few scattered punctures near basal border; anterior border straight. Anterior border of prosternum concave, very narrow before procoxae; prosternal process about half as wide as transverse diameter of procoxae, transversely expanded at apex to enclose procoxae posteriorly, finely rugose, with relatively long, erect fine whitish hairs. Mesoventrite as wide as prosternal process basally, shortly spatulate at apex, glossy with fine punctures and fine short whitish hairs. Metaventrite slightly longer than mesoventral process, glossy and glabrous on disc, with sparse punctures basally and deep median longitudinal notch at posterior border; sides moderately rugose-punctate, with relatively dense short appressed fine whitish hairs. Scutellum arched, slightly longer than wide at base, round at apex, glossy with few scattered punctures on disc. Elytra long, slightly wider at base than base of pronotum, gently curved at sides, broadest at middle and regularly curved at apex; elytra with very weak transverse impression at basal 1/3; humeri strongly marked, concealing elytral margin from above, unpunctured; eight regular striae on each elytron, with only striae 3–5 slightly disarranged at basal third, impressed with longitudinally conjoined slit-like small punctation mostly on disc and inner striae or dot-like deep punctures elsewhere, larger in posthumeral area; additional short scutellar stria of small punctures, double basally, reaching basal 1/3 of elytra and short subhumeral dotted, curved stria joining marginal bead of punctures before middle of elytron; intervals weakly convex basally and on disc, more convex at apical and lateral declivities of elytra; intervals glossy, with very fine, scattered dot-like punctures. Femora dilated at middle; tibiae weakly curved, shorter than corresponding femur; tarsi shorter than corresponding tibia, with first pro- and mesotarsomeres strongly dilated in males; claws appendiculate. Abdominal ventrites finely shagreened; basal process and sides of first ventrite with fine punctures and sparse fine whitish hairs; ventrites 2–4 with sparse short whitish hairs at apical half; last visible ventrite emarginate at apical border with sparse erect fine setae close to border. Penis (Fig. 2f) proportionally small, narrow and slender, strongly curved ventrally at base, nearly straight at middle, tapering and slightly curved ventrally at apex, with tip pointing ventrally; sides subparallel in dorso-ventral view, widened preapically at level with operculum, smoothly curved and slightly elongate and round at apex.
Females (Fig. 4d): The metallic shine of females is bronzy instead of green, and besides the lack of tarsal modifications, they also have a slightly heavier built, the last visible ventrite of their abdomen is entire and, as most females of Kumatoeides gen. nov., they have the intervals in lateral declivities of elytra more strongly raised. Spermatheca (Fig. 5d) weakly sigmoidal; cornu bulbous, longer than wide, slightly strangled at base, connected to nodulus, twice as long as cornu, strongly narrowed at middle, at level with insertion of spermathecal gland, bulbous at basal half, with spermathecal duct inserted prebasally, opposite to cornu orientation.
Diagnosis: This is the only species of Kumatoeides gen. nov. with dorsal metallic surfaces. A similar species, and possibly the closest known relative, K. anomala sp. nov., which is also found in the Mt. Mandjélia, has a hint of metallic shine on head and pronotum, but otherwise it is perfectly recognizable by the scrambled punctation basally on elytra. The two species have very similar spermathecae, more stylized in the case of K. metallica sp. nov.
Derivatio nominis: The name is a feminine form for the adjectives metallicum (Latin) or µεταλλικóς (Greek), referred to the metallic appearance of dorsal integuments of the insect.
Distribution: Kumatoeides metallica sp. nov. is only known from mid to high elevations in Mt. Mandjélia, on the northern part of the Massif du Panié (Fig. 3a).
