Description. Holotype, Male. ( Fig. 5A View Fig ) Dimensions: LB: 8,6, LR: 1,9, WR: 1,3, LP: 3,2, WP: 3,2, LE: 5,4, WE: 3,5. N = 1 for all measurements.
Coloration. Integument black. Body surface, rostrum, head, and underside moderately shiny, with markings of round, metallic, green to reddish scales.
Head. Dorsal surface and lateral sides without scally markings; surface between eyes with single white setae; genae covered with white to greenish shiny hair-like scales, increasing intensity to ventral surface; forehead flattish; moderate medial longitudinal furrow from base of the eyes to base of the forehead; transverse groove at the base of the eyes confluent with medial furrow; eyes medium-sized, moderately convex from outline of head.
Rostrum. Longer than wide (LR/WR: 1,46), moderately rugose on all length; basal half covered with white setae; finely punctured on all length; without colourful scales; dorsum with deep medial furrow from base to anterior ½ forming moderate medial concavity; in dorsal contour nearly straight; in lateral contour convex dorsally, with moderate dorsal bulge; moderate furrow from base of eye to antennal scape; ventral part covered with setae and longer, white hairs; lateral parts without puncture.
Antennae with antennal scape nearly same length as funicle, scape reaching beyond hind margin of eye; sparse setae at anterior half; funicular segment 1,5 times longer than II, segment II 1,5 times longer than III, segments III – VI as long as wide, segment VII wider than long, club sub-ellipsoidal, 2,5 times as long as wide.
Prothorax sub globular, as long as wide (LP/WP: 1), strongly punctured with sparse corresponding setae; widest just before the middle, moderately convex in dorsal view; with moderate medial longitudinal groove at
279 disc; with the following markings of round, metallic green to goldish, yellowish shales: two roundish dots medially at disc, each redirected laterally; confluent anterior and posterior transverse groove at all length.
Elytra sub-ellipsoidal, (LE/WE: 1,54), slightly wider than prothorax and moderately longer than prothorax (WE/WP: 1,09; LE/WP: 1,68); striate punctate near suture, irregular puncture towards dorsolateral sides; in dorsal contour widest just at the middle, slightly convex; each elytron with the following scally markings of round, metallic green to goldish, yellow scales: 1) two roundish spots at medial part, one along intervals II to III, one redirected laterally; 2) two roundish spots at apical part along intervals II to III, one along apical ½,
280 one redirected to apex; spots can vary in size from smaller to larger, some exemplars have two additional roundish spots at sub-basal part, one along intervals II to III, one redirected laterally; larger growths at each elytral shoulder that vary in number along individuals.
Femora covered with rare white to golden setae and hair-like scales in all length; femora, tibia and tarsus without scally markings; fore-tibia with longer, brownish setae that are more intense along internal margin and towards anterior part and moderate denticules along internal margin; mid and hind tibiae with less dense setae, without denticles along internal margin. Male genitalia as shown in Fig. 5C, D View Fig .
Female. Elytra more ovate; genitalia as shown in Fig. 5 View Fig E-G; spots on disc of prothorax redirected posteriorly, with additional transverse line of scales along anterior margin; disc of prothorax without longitudinal medial groove.
Differential analyses. M. romblonensis sp. nov. in general appearance is unique for fauna of Sibuyan but can be related to M. (M.) puncticollis Heller, 1912 by general appearance and scally markings of metallic green colour. The new species can be distinguished by unique growths at each elytral shoulder, dorsally convex rostrum in lateral view that is widest at base ( M. romblonensis sp. new.) not at sub-apical part ( M. (M.) puncticollis Heller, 1912 ) ( Fig. 6C View Fig ).
Distribution. Sibuyan Island, Romblon.
Etymology. The specific epithet is a toponym to the type locality to Romblon Island, Philippines.
