Description. Measurements (n=2): LB: 13.3-14.9 (holotype 14.9; mean 14.1); LR: 2.1 (holotype 2.1; mean 2.1); WR: 1.5-1.6 (holotype 1.5; mean 1.55); LP: 3.2-3.3 (holotype 3.3; mean 3.25); WP: 3.0-3.1 (holotype 3.0; mean 3.05); LE: 8.2-8.8 (holotype 8.8; mean 8.5); WE: 5.0-5.3 (holotype 5.3; mean 5.15).
Body black, shiny except for ventral side with weaker lustre, with markings of metallic blue, green to yellow scales on all parts except for femur, tibia and dorso-lateral part of prothorax, mixed with pale brown scales; single scales round, groups of scales recumbent; scales on antenna and coxa elongate. Dorsal surface of head with indistinct punctuation, lateral portions with strong punctation, distinctly engraved in posterior portion behind the eyes. Eyes small, strongly prominent, if see dorsally. Dorsoapical portion weakly bulging dorsally along ½ of the forehead, three times as wide as eye. Rostrum 1.5 times as long as head, longer than wide (LR/WR 1.4) with distinct longitudinal medial groove stretching from base of dorsal part of forehead to apical 1/3, and with sparse light brown hairs on basal part to middle of forehead; two large elevated portions on each side of longitudinal medial groove, bulges narrowing along apical part and extended to base; apical part with distinct transverse groove along apical third; deep subovate impression from apical ½ to mouthparts, impression distinctly incurved on apex; two large bulges on each side of impres-

sion; lateral and ventral parts covered with metallic green to golden scales; short, wide, light brown hairs on apical part; antennal scrobe reaching anterior margin of eye, two large bulges on sides of antennal scrobe, bulges distinct from dorsal surface of rostrum; in dorsal contour rostrum wider in basal part, narrowing toward middle and distinctly raised to apex; ventroapical portion of rostrum strongly widened and markedly convex; in lateral contour distinctly rounded from base to apex. Antennal scape covered with white pink scales along internal margin; scape straight, widened to apex; antennal scape with short and strong variable hairs, arranged in longitudinal rows; basal antennomere twice as long as wide, slightly widened to apex, same length as antenomere II; antenomere II 1.5 times as long as wide along apex and two times as long as wide along basal part, twice longer than antenomeres III-VI; III-VI subequal in size, same length and width, same length with VII, but narrower; club straight from base to just before the medial portion widest at apical 1/2, three times as long as wide. Prothorax strongly rugose, sub-rectangular, with very fine punctation, slightly longer than wide (LP/WP 1.1), anterior margin straight, slightly bulging dorsally, with hair-like scales on lateral parts, posterior margin slightly curved, with fine, deep, lanceolate medial groove on dorsum; pronotum with the following markings: 1) two longitudinal scale lines on each side of medial groove; 2) wide longitudinal scale line stretching from dorsolateral part to lateral ½; 3) patch of scales on each lateroventral part; 4) ventral part completely covered with single scales; ventral part with two transverse grooves, one along posterior, one along anterior margin; in dorsal contour widest in middle, in lateral contour without

bulges, with narrow impression at apical half. Elytra slender, LE/WE 1.66, with deep longitudinal grooves, strongly rugose, punctation very indistinct, corresponds groves, short, brown hairs in all length, hairs longer and denser from apical half of elytra to apex; each elytron with fine longitudinal scale line at suture and one more at lateral margin, with number of chaotically dispersed scally spots, number of scally spots vary in some specimens; elytra distinctly narrowed toward apical third, with slightly rounded apical margins; LE/LP 2.67, WE/WP 1.77; elytra more convex in middle, if see laterally, with incurved laterobasal margin; ventral surface of the body completely covered with single scales except for ventrites III-IV with few single scales at lateral parts; ventrite V with brown hair-like scales along outer margin. Coxa covered with elongated scales (procoxa completely, mid and hind coxa in inner part); femur densely covered with single scales in all length except for apical half, without or with few scales, two rows of long, dark brown hairs, one at inner margin, one in outer margin; tibia with line of scales at inner margin, mingled with long, dark hairs in all length; tarsus with small, round scales, mingled with short, pale hairs; tarsite I and II subequal in size, tarsite III larger. Aedeagus as in Fig. 2.10 View Fig -13.
Female. Measurements (n=3): LB: 15.1-15.5 (mean 15.27); LR: 2.5-2.7 (mean 2.6); WR: 1.3-1.6 (mean 1.43); LP 3.0-3.4 (mean 3.23); WP: 3.8-4.2 (mean 4.0); LE: 8.6-9.2 (mean 8.8); WE: 5.6-6.9 (mean 6.43). Larger, elytra widest just at the middle, in lateral contour incurved at sub-basal part, widened to widest middle and slightly narrowed to apical ½, after sharply decreased to apex. Genitalia as shown in Fig. 2.14 View Fig -17.
Etymology. The specific epithet is the Latinised adjective derived from the area the specimens were collected from.
Mimicry. The colour pattern of this species corresponds to Expachyrhynchus palawanensis Rukmane, 2019 ( Fig. 4), which was described from the same location in Palawan Island (Rukmane 2019).
