Diagnosis: Metapocyrtus kuehli sp.nov. superficially resembles the elytral patterns of Metapocyrtus (Orthocyrtus) mansaka Cabras, Bollino & Medina, 2018 but is not related at all. Metapocyrtus kuehli sp.nov. is most related to Metapocyrtus lindabonus Schultze, 1922 but differs from the latter by having wider, and less rugose rostrum with nearly well-defined edges and faint medial groove, presence of two thin bands on anterior and posterior margin of pronotum, having wider and more convex elytra with three prominent, broad, and defined transverse bands. The genitalia of Metapocyrtus kuehli sp.nov. has a more blunt and bigger apical orifice and longer temones.
Description: Dimensions: LB: 10.0- 12.5 mm (holotype 12.5 mm, â: 11.06). LR: 2.0- 2.5 mm (2.5 mm, â: 2.21). WR: 1.4-1.7 mm (1.7 mm, â: 1.53). LP: 3.0- 4.0 mm (4.0 mm, â: 3.42).WP: 3.0- 4.0 (4.0 mm, â: 3.42). LE: 7.0- 8.5 mm (8.5 mm, â: 7.73). WE: 4.5- 5.4 mm (5.4, â:4.9). N=20.
Integument black. Body surface shiny.
Body mostly glabrous. Head mostly glabrous, sparsely pubescent with minute hairs; forehead between eyes with short adpressed brown hair; median groove distinct reaching the vertex; lateroventral side with yellow-green hairlike scales. Rostrum weakly rugose on basal half, minutely punctured on apical half, longer than wide (LR/WR: 1.47), bearing minute light brown hairs in the dorsal surface, and long light brown hairs at the lateral sides and anterolateral margin; transverse basal groove distinct; longitudinal groove along the midline on basal half slightly distinct; dorsum finely punctured; dorsal surface weakly convex. Eyes medium-sized and feebly convex. Antennal scape and the funicle nearly as long, moderately covered with fine light-colored hairs. Funicular segments I and II are almost of the same length, 3 times longer than wide; segments III-VII nearly as long as wide; club sub-ellipsoidal, nearly 3 times longer than wide.
Prothorax subglobular, as long as wide(LP /WP: 1.0), glabrous, widest at middle, weakly convex, with the following scaly markings of cream and turquoise round scales: a) thin band at the anterior margin, b) thin band at the posterior margin, and c) broad lateroventral stripe before the coxa confluent with the anterior and posterior marginal band.
Elytra ovate (LE /WE:1.57), nearly as wide but moderately longer than prothorax(WE /WP: 1.35, LE / LP: 2.13), black, sub-glabrous, with very minute and sparse setiferous punctures, moderately convex, apex rounded, sparsely covered with light colored fine hairs. Each elytron with the following scaly bands of cream, blue, and turquoise-colored round scales: a) basal transverse band which extends from stria I to lateral margin, b) median transverse band from stria I to lateral margin, c) short post-median stripe on lateral margin which reaches apical ¼ and confluent with median band, and d) subtriangular band on apical 1/3 extending from stria I to interval VIII. Each band prominently with blue and turquoise scales and cream-colored scales towards the outer margin.
Legs with moderately clavate femora. Femora, and tibiae covered with light-colored hair. Tibiae covered with sub recumbent light-colored bristles, short on outer margin and long on the inner edge, moderately serrate along the inner edge. Fore and mid tibiae bear mucro at the apex. Tarsomeres are covered with sparse pubescence. Coxae with light-colored hair. Mesoventrite with light-colored adpressed bristles. Metaventrite with light-colored adpressed bristles, very sparse turquoise hair-like scales, and round cream-colored scales towards margin. Ventrite I depressed on disc with light-colored adpressed bristles. Ventrite II with long light brown adpressed bristles dense at middle and short 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 2 A-C.
Female. Dimensions: LB: 11.1-13.5 mm (â: 12.9 mm): LR: 1.8-2.0 mm (â: 1.95 mm): WR: 1.3-1.8 mm (â:1.68). LP: 3.1- 4.0 mm (â: 3.78 mm). WP: 3.1-5.0 (â:4.53). LE: 8.0- 9.8 mm (â:9.35). WE: 5.5-7.5 mm (â:7.0). N=15.
Habitus as shown in Figure 1 B-D
Pronotum wider than long, slightly shorter than in the male, not perfectly subglobular. Elytra longer and wider than in male, widest at middle and strongly convex; lateral side with a moderate depression just before the margin. Otherwise mentioned, similar to male.
Female genitalia as shown in Figure 2 D-F
Etymology. Kuehli, a noun in genitive case, name after Dr.Yannick Kuehl for his help in promoting research and conservation activities of Philippine biodiversity through the National Geographic Society.
Distribution. Metapocyrtus kuehli sp.n. is known from Maragusan, Davao de Oro. So far this is the only known locality of this species.
