Distribution. Philippines, Luzon (Prov. Aurora: Dingalan, Prov. Mt. Province, Prov. Nueva Vizcaya: Imugan, Kayapa,).

Diagnosis. Distinguished by the dark femora and the color of the elytra.

Re-description. Size: Total length (without labrum) 5.3–6.2 mm (mean = 5.7 mm, n = 13). Head: Dark coppery above; 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 ratio between width of head and elytra = 1.3 in medium. Labrum (male Fig. 15 , female Fig. 16 ) distinctly wider than long, ratio between width and length = 2.5 in medium; with six to seven marginal setae, unidentate in the middle of front edge; color blackish brown, in some specimens with a small metallic luster at the lateral margin. Mandibles yellowish, more or less rufescent on apical and inner teeth. 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 half of the elytral length in the males, a little shorter in the females; antennomeres one to four dark, with metallic luster; scape with one long apical seta, the other three antennomeres almost glabrous; 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, glabrous or with some white setae at lateral margin, transversely waved at lateral margin, remainder with irregular wrinkles; color dark coppery. Sternae and episternae metallic dark coppery, proepisternum with some white setae marginally; mesepisternum glabrous, the remaining setose; mesepisternum of females with a longitudinal furrow in the upper half. Elytra: ( Fig. 12–13 ) parallel-sided, somewhat rounded in the middle; color dull brown, apically lightened in some specimens, lateral margin blackish cupreous; elytral testaceous maculation consists of a slender middle band, which nearly reaches the middle suture, and a medium sized subapical dot; a small subhumeral dot is present or lost. Surface with a fine microsculpture, and many larger, evenly spaced punctures laterally; preapical impression strong, apical microserration fine and irregular in some specimens; apical border distinctly rounded and restricted towards middle suture, with a small sutural spine. Epipleurae rufous. Ventral aspect: Venter setose, dark brown, with metallic luster in some specimens; coxae with white setae; trochanters testaceous; coxae, femora, tibiae and tarsi dark, with little metallic reflections; legs covered with some with setae, mesotibiae more densely setose. Aedeagus: ( Fig. 14 ) on left lateral view fusiform, straight, tapering, slightly enlarged in the middle, with a straight, blunt apex, slightly knobbed and curved downwards (total length 2.4 mm).
