Fig. 3 , 4E,F,G .

Type material. Female. Holotype. ‘’ PHILIPPINES / Luzon, Dingalan , Aurora / I. 2019 / local collector leg.’’ (white rectangular label, printed); ‘’ HOLOTYPE / Pachyrhynchus phaleratus ssp. dannylayroni / Rukmane, 2019 / det. Rukmane A. 2019’’ (red rectangular label, printed) .

Distribution: Luzon Island, Aurora Province.

Description. Female. Measurements (Holotype): LB: 13.1; LR: 1.9; WR: 1.8; LP: 4.0; WP: 3.7; LE: 8.9; WE: 6.2. Rostrum wider than long, LR/WR 1,05; pronotum slightly longer than wide, LP/WP 1.08; elytra nearly 1.5 times longer than wide, LE/ WE 1.44; elytra more than two times as long as prothorax, LE/LP 2.23; elytra wider than prothorax, WE/WP 1.66. Body surface black, shiny, with pale green markings of round to recumbent scales. Dorsal habitus as shown in Fig.3 . Prothorax with same markings as in P.phaleratus ssp. phaleratus .

part, from base to submedial part; 2) longitudinal line along lateral margin in all length; 3) two elongated sutural patches at apical part; 4) two roundish patches medially, two roundish patches at apical ½; 5) longitudinal stripe from the middle to apical 1/2 along interval IV; 6) triangular patch near apex laterally; elytra widest just in the middle, apex firmly rounded. Metasternum covered with round pale green scales; two patches on ventrite I, each redirected laterally; round patch of scales on each side of ventrite II. Genitalia as illustrated in Fig. 4 E-G.

Male unknown.

Differential analyses. This new subspecies is delimitated from P.phaleratus ssp. phaleratus mainly by its unique markings on elytra, which are much more thick than in P.phaleartus ssp. phaleratus .

Etymology. This subspecies was named after Danny Layron in appreciation of cooperation and possibility to study current material.
