except area around the eyes, with small patch of scales along inner margin of each eye. Forehead with moderate dorsal bulge, 2.5 times as wide as eye width. Rostrum roughly dotted, longer than wide: LR/WR, dorsally with oblong medial bulge and two weak impressions one on each side, subbasal lateral impression very weak; lateral parts with metallic scales only on latero-ventral part. Antenna strongly punctured on all length; basal antennomere 1.5 times as long as wide, slightly shorter than antennomere II; antennomere II two times as long as wide, 1.5 times longer than III-VI; III-VI subequal in size, same length and width, shorter than antennomere VII; antennomere VII longer than wide; club strongly elongated, narrow at base, widest just after the middle. Prothorax finely punctured, (LP/ WP 1.04); anterior edge straight; posterior edge straight dorsally, dorso-lateral part slightly bended then strongly folded to underside, mingled with short light hairs along dorsal part; prothorax with the following markings: 1) two longitudinal spots medially on disc, each slightly redirected laterally from the middline; 2) longitudinal line along middline of each lateral part, line widened toward apex; 3) ventral part above coxae with transverse line of metallic pink scales and small patches of scales below coxae. Elytra widest just at the middle, LE/WE 1.4, intervals smooth, corresponded by shallow puncture rows with short, light brown hairs; subbasal part folded, apical part without long, dark hairs; each elytron with the following scally markings: 1) patch of scales along subbasal fold; 2) interrupted longitudinal line of scales along lateral margin; 3) 1-5 small patches at apical part towards apex; 4) interrupted transverse line slightly below midline from interval II to lateral margin; 5) 3-6 small patches at basal part. In lateral contour widest just after the midline towards apex. LE/LP 2.52, WE/WP 1.86. Femur with two longitudinal line of scales, one along inner, one along outer margin. Hind tarsite II very short, wider than long. Aedeagus as in Fig. 3. 11-13. Eversion of endophallus as shown in Fig. 5B, 6B.

Female ( Fig. 3.1-5, 3.15 -16). Measurements (n=5): LB: 15.7-18.9 (mean 16.86); LR: 2.3-2.5 (mean 2.38); WR: 2.0-2.4 (mean 2.18); LP: 3.2-3.9 (mean 3.46); WP: 3.5-4.1 (mean 3.68); LE: 9.8-11.4 (mean 10.36); WE: 6.2-7.8 (mean 6.86).

Differential analyses. Polycatus caterinae sp. nov. is similar to P. barsevskisi sp. nov, P. panayensis Schultze, 1918 and P. negrosensis by it’s markings on disc of pronotum. Species might be easily distinguished from the rest of the species by its smooth intervals on elytra, rostrum with shallow impressions dorsally and II segment of tarsus, that is wider than long.

Etymology. The species is dedicated to Caterina Moriconi wife of one of the authors (Alessandro Bramanti).
