Diagnosis. Metapocyrtus um is distinct among the endemic Metapocyrtus in Mindanao. The unique coloration of the elytra with intervals I–III reddish brown, the ornamentation of the pronotum and the elytra with sparse light-yellow ochre and turquoise round scales on the dorsolateral sides, and the ovate elytra with the dorsum moderately and uniformly convex in profile with a steep apical declivity, easily distinguishes this species from its congeners.

Description. Male. Dimensions: LB: 9.0–9.9 (holotype 9.0mm). LR: 2.0–2.2 (2.0mm). WR: 1.2–1.32 (1.2mm). LP: 3.2–3.52 (3.2mm). WP: 3.0–3.3 (3.0mm). LE: 6.5– 7.15 (6.5mm). WE: 5.0–5.5 (5.0mm). N=2.

Integument of elytra and legs reddish brown and black; head, rostrum, antennae and tarsi black. Body surface, rostrum, head, and underside with a weak luster. Body subglabrous. Head finely punctured, sparsely minutely pubescent, dorsally with dispersed metallic pale-yellow ochre round to elliptic scales, with pale-yellow ochre setae on lateroventral parts; forehead between eyes not depressed, with scattered light-yellow ochre round scales and sub-adpressed white setae. Rostrum weakly rugose on basal half, finely punctured on apical half, nearly twice longer than wide (LR/WR:2/ 1.2mm), bearing whitish, moderately long suberect adpressed setae on dorsum and longer whitish suberect setae on lateral and ventral surface interspersed with adpressed hairs; transverse basal groove distinct but not reaching lateral margin; longitudinal groove along midline distinct; dorsal surface almost flat, apex weakly convex. Eyes medium-sized, feebly convex. Antennal scape and funicle of almost same length, covered with suberect adpressed fine light-colored hairs. Funicular segments I and II almost of same length, three times longer than wide; segments III–VII nearly as long as wide; club sub-ellipsoidal, nearly 3 times longer than wide. Prothorax sub-globular, nearly as long as wide (LP/WP:3/ 3.2mm), surface black with a tinge of red on apical half, finely punctured, sparsely minutely pubescent, widest at middle, nearly flattish on dorsal surface, sparsely covered with light yellow ochre and turquoise round scales, with turquoise setae on lateral surface. Elytra ovate (LE/WE:6.5/ 5mm), slightly wider and twice longer than prothorax (WE/WP: 5/ 3mm, LE/LP: 6.5/ 3.2mm), finely punctured, minutely pubescent, dorsum moderately uniformly convex in profile, with steep apical declivity, apex with dense long white hairs; body surface mostly black except for intervals I–III reddish brown, sparsely covered with light-yellow ochre and turquoise round scales on dorsolateral side which become denser towards lateral margin. Legs with moderately clavate femora. Femora red in color, black toward apical margin, densely covered with suberect long white setae. Tibiae covered with suberect long white setae, weakly serrate along inner edge. Fore tibiae with mucro at apex. Tarsomeres covered with sparse pubescence. Coxae covered with pale bluish to yellowish setae and with sparse turquoise elliptical scales. Mesoventrite covered with light colored subadpressed setae. Metaventrite with light colored adpressed setae and dense light yellow-ochre round scales on lateral sides. Ventrite I depressed at middle with colored adpressed setae, very dense yellow adpressed setae towards middle, sparse light yellow-ochre and turquoise round scales towards lateral margins. Ventrite II to V sparsely covered with adpressed setae. Ventrite V flattened, apical half finely densely punctured, with minute hairs and long whitish and bluish setae.Male endophallus as shown in Figure 1 E, F .

Female. Dimensions: LB: 12.0– 12.7mm: LR: 2.0– 2.1mm: WR: 1.7–1.8mm. LP: 3.0– 3.2mm. WP: 4.2–4.5mm. LE: 9.0– 9.5mm. WE: 6.9–7.5mm. N=2.

Etymology. The new species is named after the initials of the University of Mindanao, UM. The color of the new species is reminiscent of the university’s color symbol.

Distribution. Metapocyrtus um is known from Mt. Malambo, Marilog, Davao City.

DNA barcode. The sequence record is deposited in the NCBI (National Center for Biotechnology Information) database with accession number: OL333551 .
