DiagNosis. This new species is similar to P. clavata Du, Li et Wang, 2011 and P. subclavata Du, Wang et Li, 2014 in the male genitalia. It can be distinguished from P. clavata and P. subclavata by the costa having a digitate process, which is spine-shaped in P. clavata and absent in P. subclavata. The new species is also similar to P. saligna Du et Wang, 2012, but it can be separated by the slender juxta lobe almost reaching the apex of the uncus and the slender aedeagus more than four times the length of the saccus; in the latter species, the strong juxta lobe reaches before the base of the uncus and the thick aedeagus is approximately 2.5 times the length of the saccus.
DescriptioN. Adult (Fig. 3) wingspan 8.0‒11.0 mm. Head with vertex shining white, frons khaki, occiput deep ochreous brown. Labial palpus with first and second segments pale ochreous yellow; third segment white except brown distally, about same length as second. Antenna with scape white; flagellum white on basal 1/3 and white annulated with black on distal 2/3 on dorsal surface, blackish brown on ventral surface. Thorax and tegula deep ochreous brown. Forewing orange yellow to ochreous yellow; antemedian fascia white edged with black scales, straight and uniform, extending from costal 1/4 obliquely outward to basal 3/5 of dorsum; costal spot at basal 3/4, white edged with black scales except along costal margin, sub-rounded, large and occupying anterior 2/3 of wing width; cilia gray mixed with black, except white around apex. Hindwing and cilia gray. Fore- and midlegs black, mid tibia with a tuft of long white scales at apex, tarsi marked with white at apex of each tarsomere; hindleg grayish brown, tarsus marked with white at apex of each tarsomere.
Male genitalia (Fig. 11). Uncus wide at base, narrowed toward apex, distal 2/5 furcate, forming two slender processes narrowly rounded at apex. Gnathos very narrow, sub-triangular, approximately 2/3 length of uncus. Tegumen divided from posterior 1/4, not distinctly narrowed anteriorly. Valva slightly widened medially, narrowed to rounded apex, with a tuft of dense setae distally; costa slightly arched, with a digitate process at middle. Sacculus extremely long and narrow, more than twice length of costa, setose distally. Saccus broad, longer than uncus, blunt at apex. Juxta not divided, extremely long, almost reaching apex of uncus; basal lobe reaching before apex of saccus. Aedeagus thick, as long as or slightly longer than sacculus; cornutus thorn-like, approximately 1/8 length of aedeagus, placed beyond middle.
Female genitalia (Fig. 16). Apophyses anteriores about 3/5 length of apophyses posteriores. Lamella postvaginalis rectangular, posteromedially overlapped with a triangular plate bearing dense setae. Antrum subtriangular, scobinate on ventral surface, slightly protruded posteromedially. Ductus bursae with basal 2/3 entirely sclerotized; distal 1/3 dilated, partially membranous, with large sclerites bearing denticles. Corpus bursae elliptical; signum absent.
DistributioN. China (Hainan).
Etymology. The specific epithet is derived from the Latin simil- and the specific name of another species, referring to the similarity of the two species.
