(white label) ( BRAA) ; 3 females - PHILIPPINES / Luzon, Laguna prov., Santa Maria / III. 2018 / local collector leg. (white label) ( DUBC). All with additional red label : ‘’ PARATYPE / Eupyrgops mitoraji Bramanti & Bramanti 2020 ’’.

Distribution. Luzon Island, Quezon and Laguna provinces (Fig. 8).

Description. Female. Body length: 13.7 – 14.8 (mean 14.23, n=3); width: 7.1 – 8.2 (mean 7.8, n=3). Integument black, body surface shiny except underside with weaker luster, with markings of yellow to orange round to recumbent scales with golden reflections.

Head slightly pubescent, with general puncture. Forehead slightly raised dorsally, with general round scales between the eyes; clearly divided from the rostrum by a transverse groove. Eyes rather big, two times as wide as forehead, strongly prominent from the outline of the head, peak just after the middle. Rostrum strongly bulging dorsally, in lateral view metarostrum straight, with deep puncture, prorostrum oblique, with weaker puncture. Antennal scrobe short, do not reach anterior margin of the eye. Scape nearly same length as funicle; scape and antennomers mingled with shorter to longer yellowish hairs in all length; antennomers I-II subequal in size, twice as long as wide, two times as long as each of antennomer III-VII; antennomers III-VII subequal in size, same length and width.

Prothorax strongly punctured. With the following three scally markings: 1) sub-triangular bimodal patch medially on disc along basal margin, patch in some cases separated in the middle into two smaller patches; 2) transverse band along apical margin in all length, patch raised along medial part of the disc and interrupted along midline; 3) big patch on latero-ventral part extending to underside; In dorsal contour raised from base, widest just at the middle, then gradually narrowed to apical margin. Basal and apical margins straight. Nearly same length and width ( LP / WP 1.01).

Elytra with moderate puncture rows arranged in equal intervals. Basal half rather pubescent, apical part with longer hairs that correspond puncture. Each elytron with ten to thirteen irregularly arranged ovate scally patches that vary in size and one additional longitudinal band along lateral margin from medial portion to apex. Underside with markings of yellow to orange scales. Elytra ovate, strongly convex ( WE / LE 0.77) in dorsal contour widest just at the middle, then strongly narrowed to subapical constriction. Femur mingled with short light hairs in all length; strongly widened along medial portion; with two roundish patches along internal margin. Tibia thin and slender, covered with long golden hairs along internal margin. Spicula as illustrated in Fig. 7 . Male unknown.

Differential analyses. E. mitoraji sp. nov. in general appearance is similar to E. variabilis Yoshitake, 2017 ( Fig. 2.2 – 2.3 ) from Cayagan Valley region, but additionally to geographic isolation, new species might be easily distinguished by more strongly convex prothorax with rather deep puncture, more strongly rounded elytra together with unique scally markings.

Etymology. The new species is named in memory of the sculptor Igor Mitoraj (1944 – 2014), are genius and nature lover.
