Figs 15 , 16

Diagnosis.

This species can be recognized by the following features: (1) forewing apical band broad with large hyaline spot posteriorly; pterostigmal band with broad basal branch and thin or incomplete apical branch; marginal spot conspicuous; basal band broad; basal spots greatly reduced, faint (Figs 15C-D , 16A-B ); (2) meso- and metanotum black brown to black, with narrow or indistinct yellow mesal stripe (Figs 15C-D , 16A-B ); in males, (3) gonocoxites with 4-5 stout setae on inner apex ventrally, and triangular notch on subapical portion (Fig. 16G ); (4) parameres crossed mesally, twisted in S-shape (Fig. 16G, I ); in females, (5) medigynium with main plate broad, elongate, twice as long as wide; a pair of lateral basal plates on middle part of main plate; axis extended beyond main plate for half of its length anteriorly (Fig. 16K-L ).

Etymology.

The specific name is dedicated to Yuan Hua, the collector of the type specimens.

Description.

Male: Head (Figs 15C , 16A, C-D ): Frons, vertex and occiput yellowish brown; broad black transverse band passing through ocellar triangle and extending to inner margins of compound eyes. Rostrum yellow, with labrum brown; labial and maxillary palps yellow basally and gradually darkened towards apex, with apical segment dark brown. Antennal scape unevenly yellowish brown; pedicel and flagellum dark brown, filiform, with 35-37 flagellomeres. Thorax (Figs 15C , 16A, D ): Pronotum brownish black, bearing 10-12 black setae along anterior margin; meso- and metanotum unevenly black, bearing narrow yellow mesal stripe, with scutellum dark brown. Pleura and coxae pale. Legs yellowish, with tarsi darkened toward apices. Wings (Figs 15C , 16A ): Forewing membrane hyaline, with wing markings dark brown. Apical band broad, with hyaline inner spot. Pterostigmal band complete, with basal branch approximately three times as wide as apical branch; basal band broad; marginal spot separated, thin, striped or absent; basal spot greatly reduced. Hindwing similar to forewing, but with relatively reduced markings and slightly smaller. Abdomen (Figs 15C , 16A, E ): T2-T5 black. Notal organ of T3 flat triangular, covering acute postnotal organ on T4. A6 cylindrical, basal three-fourths brownish black, distal third yellowish brown, slightly projected on dorsal apex with sparse long dark brown setae. A7 and A8 elongate, usually yellow, constricted basally, gradually wider toward apices. Genitalia (Fig. 16F-I ): Genital bulb long oval, yellow. Epandrium broad basally, narrowed towards apex, with U-shaped terminal emargination, bearing dense setae. Cercus long clavate, expanded apically, yellowish brown, with slightly darker apex. Hypandrium with reduced stalk and pair of slender hypovalves, extending two-thirds length of gonocoxites; hypovalve bearing separated long setae on inner margin. Gonocoxite bearing 4-5 stout setae on inner apex ventrally and triangular notch on subapical portion. Gonostylus with large basal cup and obtuse triangular median tooth on inner margin. Parameres twisted in S-shape, mesally crossed, bearing dense short spines on inner margin and whole distal portion; apex long, acute. Ventral valves greatly shortened. Dorsal valves of aedeagus elongated, bearing bundle of long hairs ventrally on base and enlarged dorsal process on subapical portion dorsally. Lateral process distinctly triangular. - Female: Similar to male except, relatively denser wing markings (Figs 15D , 16B ). Genitalia (Fig. 16J-L ): Subgenital plate broad subbasally, narrowed towards apex, with V-shaped terminal emargination, bearing long setae on distal third laterally. Medigynium with well-developed main plate, twice as long as wide; middle part bearing pair of lateral basal plates; posterior arms slender, half length of main plate, forming large, deep U-shaped emargination; axis elongated, bifurcated anteriorly, extended beyond main plate for half of its length, with posterior distinctly extruded.

Distribution.

China: Chongqing, Hubei, Shaanxi.

Remarks.

This new species resembles P. sexspinosa in appearance, but can be readily differentiated from the latter by: (1) meso- and metanotum unevenly black, bearing an indistinct narrow (cf. distinct) yellow mesal stripe; (2) basal spot greatly reduced (cf. absent); (3) hypovalve extremely slender (cf. broad); separated (cf. dense) long setae on inner margin; (4) middle (cf. basal) region of medigynium bearing a pair of lateral basal plates.
