Diagnosis. Metapocyrtus (Metapocyrtus) ilgas sp. nov. is distinguished from any other Metapocyrtus species in Panay Island based on its unique pronotal and elytral markings.
Description. Male. Dimensions: LB: 9.3mm. LR: 1.8mm. WR: 1.8mm. LP: 3.5mm. WP: 3.5mm. LE: 5.8mm. WE: 4.3mm. N=1.
Integument black. Body surface, rostrum, head, and underside with weak luster.
Head finely punctured on dorsum with few sparse pubescence, frons with sparse pink, round scales, lateroventral parts below the eye with sparse pink elliptical scales with very few piliform scales, forehead between eyes nearly flattish, midline groove distinct extending from the vertex towards the transverse groove. Eyes smallsized and feebly convex, barely protruding from the outline of

head. Rostrum weakly rugose with coarse punctures on basal 2/3 rd and finely punctured on apical third, as long as wide (LR/WR: 1.8mm / 1.8mm), dorsum with sparse and adpressed brownish setae, lateral surface before antennal scrobe with sparse peach elliptical scales interspersed with minute adpressed piliform scales and below antennal scrobe are long white adpressed, piliform scales, anterolateral margin with whitish, long suberect setae, ventral surface with long suberect whitish setae; transverse basal groove deep and highly distinct; longitudinal groove along midline distinct extending up to basal half; dorsum with two oblique subparallel ridges which gradually declines towards dorsolateral margins; lateral sides with weakly expanded apicad. Antennal scape slightly longer than funicle, scape reaching a little beyond the hind margin of eye, covered with subadpressed fine lightcolored hairs, and funicle with suberect yellowish hairs. Funicular segments I and II almost of the same length, three times longer than wide; segments III–VII nearly as long as wide; club subellipsoidal, nearly 3 times longer than wide. Prothorax globose, as long as wide (LP/WP: 3.5/ 3.5mm), finely punctured especially towards the anterior margin, widest at middle, moderately convex on dorsal surface, dorsal contour highest point at the middle. Prothorax with the following scaly markings of pink round scales: a) stripe at the anterior margin widened laterally, b) two subtriangular scaly markings on each side of disc starting at posterior margin tapered towards the middle, and c) broad patch before the coxa confluent with the anterior stripe. Elytra subovate, longer than wide (LE/ WE: 5.8/ 4.3mm), slightly wider and moderately longer than prothorax (WE/WP: 4.3/ 3.5mm, LE/ LP: 5.8/ 3.5mm), distinctly punctured with very minute pubescence, moderately convex, dorsal contour highest at middle, lateral contour evenly arcuate, widest at middle. Each elytron with the following scaly markings of pink and tangerine round scales: a) thick transverse basal stripe from stria II towards lateral margin, b) one longitudinal thick stripe on interval III extending from base to apex, c) thick transverse medial band from suture towards lateral margin broadened laterally, d) one long marginal stripe extending from base towards apex confluent with the basal, and medial stripe, and the long stripe at interval III, and e) skewed subcircular spot on apical third confluent with the long stripe on interval II. Legs with moderately clavate femora. Femora black covered with adpressed setae and light orange elliptical scales near the apical margin. Tibiae covered with subadpressed yellowish setae, weakly serrate along inner edge with few protruding teeth. Fore and mid tibiae bear a mucro at apex. Tarsomeres pubescent. Forecoxae covered with colored piliform scales and with light orange elliptical scales; mesocoxae and metacoxae covered with hairs. Mesoventrite covered with light colored hairs and with light orange round scales on distal ends. Metaventrite sparsely covered with light colored piliform scales and with light orange round scales on distal ends. Ventrite I slightly depressed on disc, covered with light colored piliform scales and with light yellow to orange round scales towards lateral margin. Ventrite II to V sparsely covered with whitish hairs and piliform scales which tends to get denser at distal ends. Ventrite V flattened, apical half finely coarsely rugose, with minute hairs.

Female. Dimensions: LB: 10.0mm: LR: 1.5mm: WR: 1.0mm. LP: 4.0mm. WP:4.0mm. LE: 6.0mm. WE: 4.0mm. N=1.
Habitus as shown in Figures 2 B, D View Figure 2 .
Females differ from males in the following: a) the scaly markings in head, rostrum, pronotum, elytra and legs are yellowgreen, b) elytra longer and moderately wider, and d) ventrite I slightly convex on disc. Otherwise female similar to the male.
Etymology. Metapocyrtus (Metapocyrtus) ilgas sp. nov. is named after the beetle research center of Daugavpils University in appreciation for the successful cooperation which led to the discovery of this new species.
