Etomologo: Te species name is derived from the type locality.

Description of male: Head ( Fig. 15A, B, D). Mostly greenish yellow afer death. Head including eyes as wide as the base of the mesonotum. Eyes blackish brown and ocelli yellow. Ventral part of head fuscous, with a broad yellow transverse band across head and postclypeus, which extends to anterior part of prothorax. Postclypeus moderately swollen. Anteclypeus green. Rostrum ochraceous, with apical part blackish, extending almost to posterior margin of abdominal sternite II.

Torax ( Fig. 15A, E). Pronotum longer than head, almost greenish yellow; inner area of pronotum ochraceous, with brown markings along FIssures and on parts between posterior ends of paramedian and lateral FIssures. Pronotal collar yellowish green, with brown small spot medially and two paired spots on posterolateral area; lateral part of pronotal collar obtusely dentate. Mesonotum fundamentally brown, with the following yellow markings: paired delicate fasciae along submedian sigilla, and paired lobate fasciae along parapsidal suture. Cruciform elevation yellowish green, posterior angles of cruciform elevation with black markings.

Legs ( Fig. 15C). Green, with some brown markings. Fore femora swollen and equipped with three blackish brown spines beneath: primary spine pointed and oblique to femur; secondary spine broader and erect; and subapical spine small and with acute tip.

Wings ( Fig. 15A, B). Hyaline, slightly tinged with pale brown. Forewing with fuscous spots on radial and radiomedial crossveins; marginal series of faint and minute spots present on apex of longitudinal veins of apical cells.

Abdomen ( Fig. 15A, B, E, F). Cylindrical, much longer than distance from head to cruciform elevation. Abdominal tergites brown, tergites VII and VIII darker than others, with posterior margins of each tergite narrowly black. Abdominal sternites translucent, sternites II–VI ochraceous, and sternites VII–VIII blackish ochraceous. Timbal covers semicircular and brown; timbal completely concealed by timbal cover in dorsal view. Opercula yellowish green, separated, with posterior margins semicircular and extending to posterior margin of sternite II.

Genitalia ( Fig. 15G–I). Pygofer elliptical in ventral view, yellow, with apex blackish brown. Distal shoulder of pygofer acute and erect, distally extended into pointed lobe. Upper lobes large, substantially confluent with pygofer margin in ventral view ( Fig. 15G). Basal lobes of pygofer relatively long, large, and paramedian, nearly straight and parallel to each other. Uncus trapezoid, with a narrow and short median incision. Lateral branches of uncus protruding from below uncus and each with two spines; spines comparatively short, subequal in length in ventral view.

Description of female ( Fig. 16A–E): Wingspan slightly larger. Operculum small, posterior margin just reaching abdominal sternite II. Ovipositor relatively long, narrowly indented, not protruding beyond segment IX, posterior margin of segment 7 incised at middle.

Distribution: China (Hainan).

Diagnosis features: Tis new species can be distinguished from other species of the P. linearis species complex by the obscure and fuscous spots only on radial and radiomedial crossveins of forewing and by the long lateral branches of uncus, which have comparatively short spines.
