Type depository. Holotype male in MNHN, allotype female in CDFC, paratypes in CDFC, JWGC, and ZSMC.

Type status. Paratype male in CDFC, type labels: “ PHILIPPINES, North Luzon Island, Cagayan Province, Coll. DHEURLE. Ch.; Santa Ana , VIII-2015, local collector, Ismael Lumawig lg.; PARATYPE, Cylindera (Cylinderina) , vandenberghei Dheurle, 2016 [printed, red]” . Paratype female in JWGC with same labels .

Distribution. Philippines, Luzon (Prov. Cagayan: Santa Ana).

Diagnosis. Distinguished by reddish femora and the almost shining elytra lacking maculation.

Re-description. Size: Total length (without labrum) 5.7–6.0 mm (mean = 5.8 mm, n = 2). Head: Clypeus and frons glossy dark green or dark blue, vertex and orbital plates glossy violet or greenish between orbital plates; genae violet, or greenish ventrally; surface smooth, glabrous, with each two setigerous punctures next to the eyes in front and at the center; strong longitudinal striae on vertex and orbital plates, the striae becoming slightly concentric on vertex, and finer, irregular, transversely waved, behind on neck; genae roughly longitudinally striated. Eyes pale yellow. Ratio between width of head and elytra = 1.0 in medium. Labrum (male Fig. 53 , female Fig. 54 ) distinctly wider than long (ratio between width and length = 1.8 in medium); with six marginal setae, unidentate in the middle of front edge; color glossy dark green or bluish with rufous tooth. Mandibles testaceous, teeth brownish. Labial and maxillary palpi testaceous, the last joint metallic dark; basal segment of labial palpi with long erected white setae. Antennae slender, long, reaching the apical fourth in the male, the half of the elytral length in female; scape with one long apical seta; antennomeres one and four rufous, with metallic luster; antennomeres five to eleven dark blackish brown, dull, finely and evenly pubescent. Thorax: Pronotum as wide as long (ratio between width and length = 1.0 in medium), sides straight, somewhat convergent towards base; glabrous, transversely waved before and behind the transversal constrictions and at the lateral margin, with irregular wrinkles on disc; color violet, somewhat greenish at front and base. Sternae and episternae glossy black, glabrous; mesepisternum of females with a longitudinal furrow over its whole length. Elytra: ( Fig. 51–52 ) parallel-sided; color bluish violet, with green reflections at the shoulders, broadly and curved bordered from the scutellum up to the apex by glossy violet color, with a bright glossy violet band at the front third of the elytra. Surface with a fine microsculpture above, glossy in the female, smooth in the male, with larger punctures laterally; shoulders glossy; preapical impression strong, apical microserration extremely fine; apical border distinctly rounded and restricted towards middle suture, with a tiny sutural spine. Epipleurae rufous. Ventral aspect: Venter glabrous, black; coxae glabrous, testaceous apically; trochanters glabrous and testaceous; femora, tibiae and tarsal segments testaceous, brownish apically; legs covered with some white setae, mesotibiae more densely setose. Aedeagus: ( Fig. 50 ) on left lateral view fusiform, stout and straight, tapering, slightly enlarged in the middle and concave on the other side, with a straight, blunt apex (total length 2.1mm).
