Description

Male. Dimensions (in mm): N = 2. LB 7.8-8.1 (holotype 7.8, â: 7.95), LR 1.2-1.3 (1.3, â: 7.95), WR 1.1-1.2 (1.1, â: 1.05), LP 3.0-3.1 (3.0, â: 3.05), WP 2.8-2.9 (2.8, â: 2.85), LE 4.8-5.0 (4.8, â: 4.9), WE 3.5-3.7 (3.5, â: 4.9).

Habitus as shown in Fig. 3 A-D.

Integument of elytra black; integument of pronotum, head, scape and legs dark ferruginous; funicle, tarsi, rostrum black. Body surface, rostrum and head weakly lustrous and underside subopaque.

Body subglabrous. Head subglabrous, sparsely, minutely pubescent; lateroventral parts with yellow ochre and turquoise round and elliptic scales interspersed with light-coloured recumbent piliform scales, forehead between eyes slightly depressed, covered with metallic, yellow ochre and turquoise round and elliptic scales; median groove indistinct. Ros-trum strongly rugose especially in basal half, sparsely, minutely pubescent, slightly longer than wide (LR/WR 1.18), dorsum bearing V-shape ridge and minute, light-coloured hairs; lateral surface with recumbent light-coloured hairs and long, light-brown hairs at the anterolateral mar-gin; transverse basal groove distinct, beset with sparse, light yellow ochre and torquiose round scales; dorsal surface moderately convex. Eyes medium-sized and feebly convex. Antenna clavate, scape as long as funicle, moderately covered with fine, light-coloured hairs. Funicular antennomeres I and II of the same length, nearly three times longer than wide; antennomeres III-VII as long as wide; club subovoid, nearly three times longer than wide. Prothorax globular, slightly longer than wide (LP/WP 1.07), weakly granulated with sparse pubescence, widest at mid-length, moderately convex, with a faint groove along mid-line and with the following scaly markings of metallic yellow ochre, turquoise and light blue, round scales: a) thin band approximately 1/6 length of pronotum along anterior margin, b) thin transverse band at mid-length, sometimes interrupted at centre and c) lateroventral stripe before the coxa confluent with the anterior and median bands. Elytra subelliptical (LE/WE 1.37), slightly wider and twice longer than prothorax (WE/WP 1.25, LE/LP 1.6), subglabrous, striate-punctate, weakly convex, with very minute and sparse light-coloured pubescence. Elytra with the following scaly markings of yellow ochre and turquoise, round scales: a) basal transverse band from suture towards the lateral sides, b) median transverse band, c) subtriangular patch on apical third, d) thick band along lateral margin confluent with basal band, median band and triangular patch at apical third and e) faint stripe along suture. The elytral marks seem to create four squares on the dorsum of the elytra. Apex of elytra with erect bluish piliform scales and light-coloured hairs. Legs with strongly clavate femora. Femora dark ferruginous, but black towards apical half, covered with bluish recumbent piliform scales. Tibiae dark ferruginous, but black towards apex, covered with black piliform scales towards outer surface and black erect hairs on inner margin; serrate along inner margin. Fore and mid-tibiae bearing mucro at apex. Tarsomeres covered with pubescence dorsally. Coxae with light-coloured to greenish recumbent piliform scales. Mesoventrite with sparse and minute light-coloured hairs. Metaventrite with light-coloured suberect hairs and pale yellow to turquoise, round scales at lateral sides. Ventrite I faintly depressed on disc with light-coloured, suberect hairs and sparse light-coloured piliform scales towards sides. Ventrite II with short, light-coloured, suberect hairs and sparse light-coloured piliform scales towards sides. Ventrites III-IV with sparse, light-coloured, short hairs. Ventrite V flattened, apical half finely densely punctured with suberect hairs.

Male genitalia as shown in Fig. 4 A-C. Aedeagal body short and slender and apicad bluntly produced with acute apex; aedeagal apodemes twice longer than aedeagal body.

Female. Dimensions (in mm): N = 2. LB 9.0-9.3 ( â: 9.2), LR 1.0-1.1 ( â: 1.05), WR 1.2-1.4 ( â: 1.3), LP 3.0-3.1 ( â: 3.05), WP 3.0-3.1 ( â: 3.05), LE 6.0-6.2 ( â: 6.1), WE 4.0-4.2 ( â: 4.1).

Females differ from males by the following characters: a) pronotum more convex, b) elytra obovate (LE/WE 1.47-1.62), longer and wider (WE/WP 1.33-1.35, LE/LP 2.0) than in males, c) apex of elytral declivity with tuft of bristles and e) ventrite I flattened or slightly convex on disc. Otherwise, females are similar to males.

Diagnosis

Metapocyrtus ged sp. nov. belongs to the subgenus Metapocyrtus s.s. for its rostrum with V-shape ridge and rounded dorsolateral edges, as well as elytra laterally elliptical or dorsally ovate. The species is distinct from the rest of Metapocyrtus s.s. by its unique elytral ornamentation.

Etymology

The specific epithet Metapocyrtus ged is after the acronym of Gloria E. Detoya, Chief Operating Officer/Quality Management Representative of the University of Mindanao for her unwavering support to the Coleoptera Research Center.

Distribution

The new species is, so far, known only in the Province of Davao del Sur.
