Etomologo: Te species name is derived from the type locality. Description of male: Head ( Fig. 17A, B, D). Mostly ochraceous. Head including eyes slightly wider than the base of the mesonotum. Eyes fuscous and ocelli yellow. Ventral part of head brown, with a broad pale yellowish transverse band across head and postclypeus. Postclypeus much swollen. Anteclypeus ochraceous. Rostrum yellow, with apical part blackish, extending to posterior margin of abdominal sternite II.

Thorax ( Fig. 17A, E). Pronotum longer than head, almost brown; inner area of pronotum with fuzzy fuscous longitudinal fascia medially and fuzzy patches on each side. Pronotal collar ochraceous, with a small spot medially and two pairs of blackish spots on posterolateral area; lateral part of pronotal collar obtusely dentate. Mesonotum fuscous, with the following ochraceous markings: pair of delicate fasciae along submedian sigilla reaching to half of mesonotum; paired lobate fasciae along parapsidal suture; and narrow fasciae along lateral margins of mesonotum. Cruciform elevation ochraceous, posterior angles of cruciform elevation with black markings.

Legs ( Fig. 17C). Yellowish ochraceous, with some brown patches. 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 very small.

Wings ( Fig. 17A, B). Hyaline, slightly tinged with pale brown. Forewing with distinct spots on radial, radiomedial, and medial crossveins, and obscure fuscous spot present on the mediocubital crossvein; marginal series of faint and minute spots present on apex of longitudinal veins of apical cells.

Abdomen ( Fig. 17A, B, E, F). Cylindrical, much longer than distance from head to cruciform elevation. Abdominal tergites brown, with posterior margins of each tergite narrowly black. Abdominal sternites translucent and yellow. Timbal covers semicircular and brown; timbal concealed by timbal cover in dorsal view. Opercula ochraceous, separated, with posterior margins semicircular and extending to posterior margin of sternite II.

Genitalia ( Fig. 17G–I). Pygofer elliptical in ventral view, ochraceous, with apex blackish brown. Distal shoulder broadly triangular, distally extended into pointed lobe. Upper lobe of pygofer relatively large and erect, substantially confluent with pygofer margin in ventral view ( Fig. 17G). Basal lobes large and paramedian, obliquely inward, with apex widely separated. Uncus trapezoid, with a narrow and short median incision. Lateral branches of uncus protruding from below uncus and each with spines: medial spine long and straight; lateral spine very short, lateral spine shorter than medial spine in ventral view. Description of female ( Fig. 18A–E): Wingspan slightly larger. Operculum small, posterior margin just reaching abdominal sternite II. Ovipositor relatively long, narrowly indented, protruding beyond segment IX; posterior margin of segment 7 incised at middle.

Distribution: China (Xizang).

Diagnostic features: Tis new species can be distinguished from other species of the P. linearis species complex by the large and robust body and by the junction of the radiomedial crossvein of the hindwing and the FIrst median vein of the hindwing being located nearly at the base of the FIrst median vein.

Remarks: Pomponia xizangensis was collected from Motuo County, Xizang Autonomous Region, China, and this species might also be distributed in adjacent areas in Bhutan and West Nepal.
