Other material examined. 1 male in SDEI: “ Philippinen, Luzon, Mt. Banahao ” .

Distribution. Philippines, Luzon (Prov. Quezon: Mt. Banahao).

Diagnosis. Distinguished by the reddish femora, the metallic elytral margin and the triangular middle spot.

Re-description. Size: Total length (without labrum) 5.9–6.7 mm (mean = 6.3 mm, n = 3). Head: Dark bluish green above, cupreous between orbital plates in males, genae violet, surface smooth, glabrous, each with 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, trans- versely waved, behind on neck; genae roughly longitudinally striated. Eyes pale yellow. Ratio between width of head and elytra = 1.1 in medium. Labrum (male Fig. 27 , female Fig. 28 ) distinctly wider than long, ratio between width and length = 2.1 in medium; with seven to eight marginal setae, unidentate in the middle of front edge; color rufous, at base and lateral margins with blue green hue in various extinction. Mandibles yellowish, brownish on apical and inner teeth in males and completely brownish except for the base in females. Labial and maxillary palpi testaceous, the last joint metallic dark greenish; basal segment of labial palpi with long erected white setae. Antennae slender, long, reaching the apical third of the elytral length in the males (antennae of female not complete); scape brownish yellow, with one long apical seta; antennomeres two to four mostly glabrous, brownish 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 somewhat rounded between the transversal constrictions in males, straight in the female; glabrous, with some white setae laterally before the anterior constriction; transversely waved before and behind the transversal constrictions and at the lateral margin, with irregular wrinkles on disc; color bluish green, cupreous besides the middle suture in males. Sternae and episternae metallic violet black, proepisternum with several white setae at the front margin, mesepisternum glabrous, the remaining setose; coupling sulcus of female mesepisternum not visible, due to bad condition of the specimen. Elytra: ( Fig. 25–26 ) parallel-sided, color dull brown on the disk, apically lightened at the suture; broadly bordered from the scutellum up to the apex by blue greenish color; elytral testaceous maculation consists of a small subhumeral dot, a small triangular middle dot, and a small or very small subapical dot. Surface with a fine microsculpture above, margin- ally smooth, 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 setose apically, brownish; coxae with white setae, testaceous; trochanters glabrous and testaceous; femora testaceous, brownish towards apex; tibiae and tarsi dark brownish; legs covered with some with setae, mesotibiae more densely setose. Aedeagus: ( Fig. 24 ) on left lateral view fusiform, straight, tapering, slightly enlarged at the front and the back, with a straight, blunt and slightly upturned apex (total length 2.4mm).
