Tope material: Holotype: ♂ ( NWAFU), China: Mt. Jianshan, Jinhua , Zhejiang Province, 15 June 2009, Lei Zhang leg. Paratypes: 1♂ ( NWAFU), China: Mt.Jianshan, Jinhua , Zhejiang Province, 15 June 2009, Lei Zhang leg. ; 1♂ ( NWAFU), China: Mt. Wuyi , Zhejiang Province, 20 July 2006 .

Measurements of topes: (in millimetres; 3♂♂): body length, ♂ 33.6–38.8; forewing length, ♂ 41.7–43.4; forewing width, ♂ 14.9–15.8; width of head including eyes, ♂ 9.8–10.3; pronotum width (including pronotal collar), ♂ 11.3–12.7; and mesonotum width, ♂ 9.9–10.5.

Etomologo: Te species name is a Latin adjective meaning ‘triangular’, signifying the triangular operculum.

Description of male: Head ( Fig. 13A, B, D). Mostly ochraceous. Head including eyes as wide as the base of mesonotum. Eyes fuscous and ocelli red. Ventral part of head brown, with a broad pale yellowish transverse band across head and postclypeus. Postclypeus less swollen. Anteclypeus yellowish green. Rostrum yellow, with apical part blackish, extending to trochanters of hind legs.

Torax ( Fig. 13A, 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 yellowish green, with a small spot medially and two pairs of blackish spots on posterolateral area. Mesonotum fuscous, with the following ochraceous markings: pair of delicate fasciae along submedian sigilla reaching to half of mesonotum, and irregular markings around the fasciae; and narrow fasciae along lateral margins of mesonotum. Cruciform elevation yellowish green.

Legs ( Fig. 13C). Yellowish green, with some brown patches. Fore femora swollen and equipped with three blackish brown spines beneath: primary spine pointed and slightly oblique to femur; secondary spine broader, erect; and subapical spine very small, with acute tip.

Wings ( Fig. 13A, B). Hyaline, slightly tinged with pale brown. Forewing with distinct spots on radial, radiomedial, medial, and mediocubital crossveins, and marginal series of faint and minute spots present on apex of longitudinal veins of apical cells.

Abdomen ( Fig. 13A, 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 yellow, triangular, separated from each other and broader than long, outer margins narrowly black reaching posterior margin of sternite II.

Genitalia ( Fig. 13G–I). Pygofer elliptical in ventral view, ochraceous, with apex blackish brown. Distal shoulder broadly triangular, distally extended into pointed lobe. Upper lobe of pygofer large, long, and erect. Basal lobes minute, placed laterally adjacent to side of pygofer. Uncus trapezoid, with a narrow and short median incision. Lateral branches of uncus protruding from below uncus and each with two narrow, long, and straight spines, medial spine shorter than lateral spine in ventral view.

Female: Unknown.

Distribution: China (Zhejiang).

Diagnosis features: Pomponia tricornisa can be distinguished from other species of the P. linearis species group by the long and straight spines of lateral branches of uncus, the medial spine which is shorter than the lateral spine, and the very small basal lobes of pygofer. Tis new species is most similar to P. subtilita within the P. linearis species group, but can be distinguished from P. subtilita by the triangular opercula and the large and erect upper lobe of the pygofer.
