MATERIAL EXAMINED FROM PHOTOGRAPHS. PHILIPPINES: 1 ex. ( Fig. 1 F ): Luzon, Isabela, Maconacon Forest , 17°22'27"N 122°08'42"E, 23.VII.2012, O. Ramos .

ADDITIONAL DATA. PHILIPPINES: Polillo , centre of the island ( BAKER, 1925) coordinates: 14°52'N 121°56'E ; Luzon , Quirino ( PORION & AUDIBERT, 2017) coordinates: 16°16′48″N, 121°34′48″ E .

7 MALE GENITALIA. Dark brown with dorsal portion of pygofer and basodorsal portion of gonostyli paler. Pygofer higher than long, with posterior margin slightly sinuate in lateral view ( Fig. 3 A ). Anal tube slightly elongate, 1.20 times as long as broad, broader at 2/3 of total length ( Fig. 3 B ); lateral margins slightly sinuate ( Fig. 3 B ) and apical margin strongly notched in dorsal view ( Fig. 3 B ). Gonostyli elongate with ventral margin slightly curved and posterior margin rather acutely rounded in lateral view ( Fig. 3 A ); mediobasal lateral hook projecting lateroventrally and strongly pointed, with a broadly developed basal portion ( Fig. 3 A, C ).

8 NOTE. BAKER (1925) reported that the species was “common in the forests of central Polillo”. Its relation to P. samaranus is explained under the latter. The first record of P. polillensis outside Polillo was given by NAGAI & PORION (1996: fig. 225) who illustrated a specimen from North Luzon. Recent material in the collections of MHNL, RBINS and UPLB provide a better view of the distribution of the species which appears to be widespread in the eastern part of Luzon. A rather large population was recently observed on a trunk of the hardwood tropical tree Dracontomelon dao (Blanco) Merr. & Rolfe ( Anacardiaceae ) at Mt Makiling ( Fig. 2 ), representing the southernmost record of the species as well as the first record of a host plant. Six pairs were observed on the tree ( Fig. 2 C ), indicating that July might be the reproduction period of the species. During a second survey of the same tree in September 2017, no specimen was observed.

DISTRIBUTION. Philippines: Luzon and Polillo ( Fig. 4 ).
