Diagnosis: Metapocyrtus salesi sp.n. is related to Metapocyrtus kitangladensis Cabras, Medina & Zhang, 2018 which was described from Bukidnon and Marilog, Davao City. However, M. salesi sp.n. is easily distinguishable by the following characteristics: a) smaller size, and stouter body, b) globular and more convex pronotum, c) thick longitudinal bands on each disc of pronotum, c) wider, more arcuate, and strongly convex elytra with unique scaly markings consisting of three transverse bands, and f) genitalia with shorter temones, and strongly curved ventrally near the base of aedeagal body.

Description: Dimensions: LB: 7.5-8.8 (holotype 7.5 mm, â:8.25). LR: 1.5- 1.8 (holotype 1.5 mm, â: 1.65). WR: 1.1-1.5 (holotype 1.1 mm, â:1.3). LP: 2.1-2.9 (holotype 2.1 mm, â:2.55). WP: 2.8-3.8 (holotype 2.8 mm, â:3.3). LE: 5.0-5.9 (holotype 5.0, â:5.4). WE: 3.6- 4.5 (holotype 3.6, â:4.05). N=2. Integument black. Body surface shiny.

Body subglabrous. Head subglabrous, forehead between eyes covered with metallic light-yellow ochre round scales and light-colored and red elliptical scales with a tinge of metallic purple around eyes; lateroventral parts with light yellow ochre round and elliptical scales interspersed with metallic yellow-orange hair-like elliptic scales. Rostrum weakly rugose on basal half, mostly smooth on apical half, sparsely pubescent, slightly longer than wide (LR/WR: 1.36), dorsum bearing minute yellow-orange adpressed hairlike scales, likewise on dorsolateral sides, and long light brown hairs at the anterolateral margin; transverse basal groove distinct; basal half with shallow depression beset with metallic yellow- ochrecolored round and elliptic scales; lateroventral part behind antennal scrobe densely covered with yellow-green to yellow-orange long hair-like scales; dorsal surface weakly convex. Eyes medium-sized and feebly convex. Antenna moderately clavate, scape slightly shorter than funicle, moderately covered with fine light-colored hairs. Funicular segments I and II almost of the same length, nearly 3 times longer than wide; segments III-VII slightly longer than wide; club sub-elliptical, nearly 3 times longer than wide.

Prothorax subglobular, wider than long ( LP /WP: 0.75), glabrous, widest before middle, weakly convex, disc and sides beset with yellow-orange round scales, with the following scaly markings of metallic light yellow-green round scales: a) thin band at the anterior and posterior margin, b) thin band along mid-length, c) thick longitudinal bands on each disc, and c) lateroventral stripe before the coxa confluent with the anterior and posterior marginal band.

Elytra strongly ovate ( LE /WE:1.39), wider and longer than prothorax ( WE /WP: 1.29, LE / LP: 1.39), black, sub-glabrous beset with sparse, minute and weak setiferous punctures, each puncture with light-colored short seta, strongly convex, widest at the middle. Elytra beset with yellow-orange and violet round scales, with the following scaly bands of metallic yellow, and emerald green round scales: a) irregular transverse band behind the base extending from stria I to lateral side, b) median transverse band from stria I to lateral side and c) triangular band on apical third. All three bands confluent on lateral side. Apex round with yellowish hair-like scales.

Legs with moderately clavate femora. Femora covered with light-colored hairlike scales and yellow-green and violet round to elliptic scales towards apical part. Tibiae covered with subrecumbent light-colored bristles, yellow-green, red, and violet long elliptical scales towards outer margin, and serrate along inner edge. Fore and mid tibiae bear a mucro at apex. Tarsomeres covered with pubescence. Procoxae covered with light-colored hair and with pale green and light yellow-ochre elliptic scales on the anterior side. Mesocoxae and metacoxae with light-colored hairs Mesoventrite covered with light-colored adpressed bristles and yellow-green round scales towards lateral margin.

Metaventrite with light-colored adpressed bristles and light yellow-ochre round scales at lateral margin. Ventrite I feebly depressed on disc with light-colored adpressed bristles and sparse light yellow-ochre round scales towards lateral margin. Ventrite II with long light brown adpressed bristles, shorter towards margin. Ventrites III-V with sparse light-colored short bristles. Ventrite V flattened, apical half finely densely punctured.

Male genitalia as shown in Figure 4 A-C.Aedeagal body short and stout, thick and nearly as long as its apodeme in profile; apex rounded.

Female. Dimensions: LB: 8.5-9.8 mm (â:9.15): LR: 1.5- 1.9 (â:1.7): WR: 1.1- 1.5 (â:1.3). LP: 2.4- 2.9 (â:2.65). WP: 2.9- 3.5 (â:3.2). LE: 6.0- 7.0 (â:6.5). WE: 4.8- 5.3 (â:5.05). N=2.

Habitus as shown in Figure 3 B, D .

Pronotum wider than long, slightly shorter than in the male, not perfectly subglobular. Elytra longer and wider than the male, widest at middle. Shape of the elytra ovate with a moderate depression in the lateral side just before the lateral margin. Otherwise mentioned, similar to male. Female genitalia as shown in Figure 4 D-F

Etymology. Salesi, a noun in genitive case, named after Dr. Anthony Sales, the regional director of the Department of Science and Technology in Region XI for his contribution in the advancement of research.

Distribution. Metapocyrtus salesi sp.nov. is known so far from the province of Davao de Oro
