Description. Male. Measuremants: LB: 6.7 7.2 (holotype 7.1, mean 6.98); LP: 1.7 1.9 (holotype 1.9, mean 1.82); LE: 5.0 5.3 (holotype 5.2, mean 5.16); LR: 1.2 1.3 (holotype 1.3, mean 1.26); WP: 1.7 1.8 (holotype 1.8, mean 1.76); WE: 3.6 3.8 (holotype 3.8, mean 3.7); WR: 1.1 (holotype 1.1, mean 1.1). N=5 for all measurements. Dorsal habitus as shown in Fig. 1A View Figure 1 .

Body black, with markings of glossy yellow to goldish, round to recumbent scales.

Forehead nearly three times as wide as eye width; eyes slightly prominent from the outline of the head, widest just after the middle dorsally; LR/ WR 1.18; rostrum dorsally covered with round, shiny scales except apical 1/2; frontal part of rostrum slightly widened apically; in lateral contour slightly increased just before the middle, sulcus with impression at base of the eye; lateral parts covered with round shiny scales at basal part and with scales and short light hairs at apical part; dorsal furrow of antennal scrobe sharp, wide Vshaped.

Antennal scape covered with eliptic scales from base to apical 1/2, short light hairs on all length; segments I to VII subegual in length, except segment II of slightly longer length, nearly same lenght and width, covered with eliptic shiny scales; club short, slightly longer whan wide, divided into three parts, first and third part beeing same width and second narrower; club without shiny scales.

Pronotum nearly as long as wide, LP/WP: 1.05, with the following markings of round to recumbent shiny scales: 1) longitudinal medial line at disc dorsally in all length; 2) wide longitudinal line at each dorsolateral edge in all length; 3) large patch from one lateroventral edge to other; dorsal contour slightly widened just before the middle; lateral contour straight; both basal and apical concavities covered with short, light hairs.

Femora with scally markings at basal part, bare before the middle, with markings from middle to apical half and bare to apex, mid femora with scaly markings from base to apical half, mingled with light hairs in all length; tarsus covered with scales, mingled with longer light hairs, hairs longer along inner margin.

Elytra longer than wide, LE/WE 1.37, widest just in the middle, each elytron with the following scally patches: 1) two longitudinal patches at basal 1/2, one along intervals II to III, second along intervals VI to VII; 2) four patches at medial part, one redirected apically, from middle of interval I to middle of interval III, two patches along interval V, one redirected basally, one apically, one medial patch redirected laterally along interval VII; 3) triangularshaped patch at apical part before apex; 4) two sutural patches, one before the middle, one from apical 1/2; 5) lateral margin with solid line of scales that in some cases are interupted and divided in smaller patches; in lateral contour slightly impressed just before the middle, bulged along apical 1/2 and decreased to apex.

Male genitalia as shown in Fig. 4 View Figure 4 .

Female. Measurements: LB: 7.68.0 (mean 7.78); LP: 1.9 2.1 (mean 2); LE: 5.5 5.9 (mean 5.74); LR: 1.3 1.4 (mean 1.36); WP: 1.7 1.9 (mean 1.8); WE: 4.1 4.3 (mean 4.22); WR: 1.1. N=5 for all measuremants. Dorsal habitus as shown in Fig. 1B View Figure 1 .

Differential analyses. The new species is similar to second species of the genus Excalidiopsis gen. nov.: Excalidiopsis bramanti sp. nov. Species might be distinguished by the following morphological features: 1) scally markings in E. palawanensis sp. nov. of goldish to yellowish colour, while greenish in E. bramanti sp. nov.; 2) segment II nearly same size as rest in E. palawanensis sp. nov. while at least 1.5 times longer than rest in E. bramanti sp. nov.; 3) sulcus laterally with groove at base of the eye in E. palawanensis sp. nov. and just before the distal margin of eye in E. bramanti sp. nov.; 4) dorsal furrow sharp in E. palawanensis sp. nov., but moderate in E. bramanti sp. nov.; 5) elytra of E. bramanti sp. nov. wider, more strongly rounded, in lateral contour more stronghy bulging.
