Type material. Holotype. Male. ‘’ PHILIPPINES / Luzon , Ilocos, Adams / VII. 2019 / local collector leg.’’ (white rectangular card, printed) ; ‘’ HOLOTYPE / Pachyrhynchus kirkalayroni / Rukmane, 2019 / det. Rukmane A. 2019’’ (red rectangular card, printed).
Distribution: Luzon Island, Ilocos Province.
Description. Dimensions (holotype): LB: 13.7; LE: 8.9; WE: 5.8; LP: 4.5; WP: 4.9; LR: 1.9; WR: 2.0.
Integument coppery brown, body strongly shiny except underside with weaker luster; body marked with pale green round to recumbent scales. Dorsal habitus as shown in Fig. 1D View Fig .
Rostrum wider than long (LR/WR 1.05), covered with pubescence, bulging on apical part, with peak slightly before middle, moderate subtriangular impression on basal half, two weak bulges on basal ½, longitudinal groove from middle of the rostrum to middle of forehead; lateral parts with few round scales on genae and after antennal scape; short light hairs laterally near apex mingled with few long golden hairs; antennomers rather rarely covered with long light hairs, scape covered with pubescence on basal part and few long light hairs on apical part. Head glabrous, finely punctured; eyes small, slightly prominent from the outline of the head. Forehead with weak medial impression, moderately wrinkled, nearly two times as wide as eye width.
Prothorax subspherical, wider than long (LP/WP 1.09), widest just before the middle; weakly punctured; scaly markings same as in P. sagittatus sp. nov. (see description part).
Legs thick; coxa with patch of pale green roundish scales and pubescence; femur with short light hairs on basal part and patch of round scales on apical part; hairs or scales.
Elytra subovate (LE/WE 1.53), with weakly pronounced intervals, nearly smooth; each elytron with the following scaly markings: 1) rectangular patch of scales at subbasal part from interval I to lateral margin; 2) thick transverse medial line from one lateral margin to another; 3) narrow longitudinal line at basal part before middle along interval III and one more along interval VII, lines connect rectangular patch and medial line; 4) longitudinal line along lateral margin in all length; 5) subtriangular patch at apical part from apex to apical ½ along interval II to lateral margin; widest just in the middle; on dorsal dimension narrow at the base, where gradually increased to middle, widest just in the middle, then rounded and decreased to apex.
Elytra wider than prothorax (WE/WP 1.23), nearly twice as long as prothorax (LE/LP 1.93). Genitalia as shown in Fig. 4 View Fig H-I.

Distribution: Luzon Island, Nueva Vizcaya Province.
Description. Dimensions: LB: 10.3-10.9 (Holotype 10.5, mean 10.57); LE: 7.1-7.8 (Holotype 7.1, mean 7.37); WE: 4.2-4.6 (Holotype 4.2, mean 4.4); LP: 2.9-3.3 (Holotype 3.1, mean 3.1); WP: 2.7-2.9 (Holotype 2.7, mean 2.77); LR: 1.6-1.8 (Holotype 1.7, mean 1.7); WR: 1.5-1.7 (Holotype 1.5, mean 1.57).
