Diagnosis
This species is superficially close to
P. spiraliola
sp. nov.
in forewing pattern, but it can be easily differentiated by the slightly arched subbasal band, the oblique straight antemedial band and the smaller costal patch at 2/3 that is connected to the postmedial band. The male genitalia are also characterised by the sclerotized gnathos, the saccular margin without spine-like projection, and the aedeagus, which is as long as the valva.

Description
Adult (
Figures 2
(B) and 3(B)). Head: Frons golden brown; vertex white. Antenna with scape white entirely, same length as diameter of eye; fragellum white dorsally. Labial palpus with 3rd segment dark brown, 2nd segment yellowish brown and scattered with fuscous scales, almost same length as 3rd segment. Thorax: thorax and tegula dark brown. Wing expanse 8.0–
8.5 mm
. Forewing ground colour dark brown; three bands all white edged with fuscous scales: subbasal band slightly arched towards wing base; antemedial band straightly oblique towards wing base, traversed from 1/4 of costal margin to 1/3 of posterior margin; postmedial band reaching costal patch; costal patch at 2/3, somewhat semi-circular proceeded and followed by fuscous scales; apical patch almost occupies apical part; fringes grayish dark brown, white except near apex. Hindwing more or less lanceolate; Hindwing ground colour pale grayish dark brown; Fringes dark grayish dark brown. Leg: tibia of hind leg dark brown ventrally, yellowish brown dorsally; only white at apex; one pair of asymmetric spurs at base.

Male genitalia (
Figure 4
(B,Ba–b)).
Uncus inverted and funnel-shaped, wide at base, gradually narrow to apex, round caudally, slightly bent inward, setose laterally, longer than gnathos. Gnathos tougue-shaped, wide at base, shorter than uncus. Tegumen simple. Valva simple, more or less broad; costal margin slightly dentate and setose from 4/5 to apex; saccular margin dentate and setose from 1/2 to apex. Saccus wide at base, same length as uncus. Aedeagus simple, gradually narrowed from 3/5 to apex, almost same length as valva. Cornutus dividing into 3–4 parts apically, almost half length of aedeagus.
Female genitalia (
Figure 5
(A,Aa)).
Papilla anales largely developed, setose rarely, as same length as abdominal eighth sternum. Apophyses posteriores bearing slightly broader tips anteriorly, more than 1.5 times longer than apophyses anteriores. Apophyses anteriores 1.5 times longer than abdominal eighth sternum. Lamella postvaginalis membranous, round caudally. Lamella antevaginalis large, sclerotized, and incised medially, dense setose caudally. Antrum short-cylinder, 1/3 length of papilla anales. Ductus bursae cylindrical posteriorly, gradually wider to corpus bursae. Corpus bursae large ovate, bearing tiny spines.

Etymology
The specific name of the new species is derived from the Latin,
infundibulum
(=funnel) plus –
ina
(=adjective suffix), referring to the inverted funnel-like uncus of male genitalia.
Distribution
Cambodia
(West, South; new).
