Diagnosis. The new species is unique from its congeners for its stouter body, and the presence of three longitudinal stripes in the pronotum and the two large triangular scaly patches in the elytra.

Description. Male.

Dimension: LB: 10mm. LR: 2.0mm. WR: 1.8mm. LP: 3.5mm. WP: 3.8mm. LE: 6.5mm. WE: 5.0mm. N=1

Integuments black. Body and pronotal surface, rostrum, head, legs, and underside moderately lustrous.

Head dorsal surface rugopunctate; forehead between eyes weakly and evenly depressed with distinct median ridge reaching posterior margin of eyes, sparsely adorned with appressed, round, iridescent golden yellow orange and pink scales interspersed with sparse, appressed piliform, iridescent orange scales; lateral surface below the eye with elliptical scaly markings of appressed, tessellated, round and ovate, iridescent yellow-orange scales, interspersed with pale greenish iridescent appressed piliform scales; eyes small-sized and weakly convex, not prominent on the outline of head.

Rostrum separated from the head by a distinct transverse groove almost reaching the lateral margin, coarsely rugopunctate until apical third; with subappressed, sparse, piliform iridescent turquoise scales, and distinct median furrow until the middle, adorned with sparse, appressed, iridescent, round yellow-orange scales, apical third weakly punctured with few suberect setae; slightly longer than wide (LR 2.0 mm; WR 1.8 mm), lateral surface before antennal scrobe with tessellated, appressed round and ovate, iridescent yellow-orange scales contiguous with that of the head, below antennal scrobe with suberect, piliform, iridescent turquoise scales; dorsal contour in lateral view flat until apical third then gradually declines towards apex, lateral contour in dorsal view weakly constricted at base and gradually widens towards apex; dorsolateral margin weakly rounded. Antennal scape and funicle subequal in length. Scape with sparse, subappressed setae, funicle with suberect setae. Antennae with segments 1 and 2 subequal in length, twice longer than wide; segment 3 significantly shorter than segment 1 and 2 but slightly longer than segment 4–6; segments 4 to 6 as long as wide; segment 7 slightly longer and wider than 4 to 6; club subelliptical, nearly three times longer than wide.

Prothorax subglobular, truncated at both ends, posterior margin wider than anterior margin; slightly wider than long (LP 3.5mm; WP: 3.8mm); very weakly and finely rugopunctate, punctures with appressed, minute, piliform, white setae; dorsum with the following scaly markings composed of tessellated, appressed, round, iridescent pale yellow scales: a) longitudinal stripe medially, and b) longitudinal stripes on each side of dorsum, both extending from posterior and anterior margin, c) transverse stripes on basal and apical margin, and d) thin band near lateral margin before coxae, contiguous with posterior and anterior stripes; dorsal contour in lateral view weakly convex, lateral contour in dorsal view weakly convex, widest before middle.

255 Elytra ovate, irregularly punctured, longer than wide (LE: 6.5mm; WE: 5.0mm), significantly wider and almost twice longer than prothorax (WE: 5.0mm; WP: 3.8mm; LE: 6.5mm; LP 3.5mm), each elytron covered with two broad scaly bands composed of appressed, round, iridescent golden yellowish and turquoise scales covering most of body surface except the middle and postmedial area near suture; lateral contour in dorsal view uniformly convex, slightly narrow at base then gradually widens towards middle then dilates towards a subacute apex; apex with short, suberect setae. Legs with moderately clavate femora. Femora covered with sparse subappressed, iridescent red-orange and pale green piliform scales and subapically with a patch of sparse, round and lachrymiform, iridescent red-orange scales. Tibiae denticulated and with long suberect dense setae on inner margin, weakly rugose on outer surface, and covered with sparse suberect setae that are shorter at base and longer at apex as well as sparse and appressed round red-orange iridescent scales near base. Protibiae and mesotibiae mucronate at apex. Tarsi moderately long and pubescent. Tarsomere 1 subtriangular, longer than tarsomere 2; tarsomere 2 short and triangular; tarsomere 3 bilobed, slightly longer than tarsomere 2; tarsomere 5 subequal with combined tarsomere 1 and 2; tarsal claws free.

Coxae covered with piliform scales. Procoxae with a patch of appressed, iridescent yellow-orange, round scales on anterior side. Mesoventrite sparsely covered with suberect iridescent colored piliform scales and white setae. Metaventrite covered with sparse colored piliform scales and white setae on middle and distally with patch of circular to elliptical appressed, iridescent red-orange scales. Ventrites 1 and 2 with dense suberect setae on middle and on sides with sparse, appressed, iridescent orange scales; Ventrite 1 with more dense scales than Ventrite 2. Ventrites 3–5 with sparse

256 setae. Ventrite V flattened, rugopunctate on apical half with sparse, suberect setae and sparse subappressed iridescent green piliform scales.

Female.

( Figure 2 B, D View Fig )

Dimension: LB: 12–14.1mm. LR: 1.5– 1.6mm. WR: 1.4–1.8mm. LP: 3.0– 3.5mm. WP: 3. 0– 3.5mm. LE: 7.0– 8.0mm. WE:5.0– 5.5mm. N= 2 Females differ from males in the following characteristics: a) rostrum squarish and shorter, b) forehead in between the eyes has shallow depression; b) pronotum as long as wide (LP: 3.0- 3.5mm, WP: 3. 0-3.5mm); d) pronotum with sparse minute iridescent orange scales in between the three longitudinal scaly stripes; f) apical declivity abrupt with a protruding acuminate elytral apex; g) Ventrite 1 and 2 convex; h) Ventrite 5, flattened. Otherwise, female is similar to the male.

Etymology. The specific epithet “ sidlakan ” is the Bisayan term for the east where the type localities are situated in Mindanao Island.

Distribution. Philippines (Mindanao: Davao de Oro, Maragusan, Mt. Candalaga). Philippines (Mindanao: Davao Oriental, Lupon, Brgy. Calatagan)
