Fig. 23 View Figure 23

Diagnosis.

This species can be readily recognized by the following characters: (1) forewing with apical band broad, bearing large hyaline spot on posterior margin; pterostigmal band with basal branch broad, and apical branch greatly reduced; basal band reduced into large spot near anal margin; marginal spot absent or as 1-3 small spots (Fig. 23A-B View Figure 23 ); (2) meso- and metanotum blackish brown, with prominent pale yellow mesal stripe (Fig. 23A-B View Figure 23 ); in males, (3) inner apex of gonocoxites oblique, with 6-8 dark brown setae (Fig. 23E View Figure 23 ); (4) parameres twisted in S-shape, crossed mesally (Fig. 23E-F View Figure 23 ); in females, (5) medigynium with broad main plate and pair of lateral basal plates on middle portion; posterior arms one-third as long as main plate, axis extended beyond main plate for half of its length, with posterior slightly extruded (Fig. 23J-K View Figure 23 ).

Etymology.

The specific name refers to the type locality, Yaoluoping, Yuexi, Anhui.

Material examined.

Holotype: CHINA - Anhui Prov. • ♂; Yuexi, Yaoluoping National Nature Reserve ; 18 Aug. 2013; Qiu-Lei Men leg. Paratypes: CHINA - Anhui Prov. • 3♂♂, 5♀♀; same data as holotype .

Measurements.

Male: FL = 11.4-12.0 mm, FW = 2.9-3.1 mm; HL = 10.3-11.2 mm, HW = 2.8-3.0 mm. Female: FL = 11.3-12.1 mm, FW = 3.1-3.2 mm; HL = 10.1-11.1 mm, HW = 3.0-3.1 mm.

Description.

Male: Head (Fig. 23A, C View Figure 23 ): Frons, ocellar triangle, vertex and occiput dark blown. Rostrum yellowish; labrum yellowish brown. Labial and maxillary palps yellowish basally, gradually darkening toward apex, with apical segment dark brown. Antennal scape yellowish brown; flagellum brownish black, filiform with 39-42 flagellomeres. Thorax (Fig. 23A, D View Figure 23 ): Pronotum dark brown, with 10-14 black setae along anterior margin; meso- and metanotum dark brown, with pale yellow fusiform mesal stripe; scutella pale yellow. Pleura yellow. Legs yellowish brown, with distal tarsomere dark brown. Wings (Fig. 23A View Figure 23 ): Membrane hyaline, with brown markings. Forewing with apical band broad, bearing large hyaline spot on posterior margin; pterostigmal band with basal branch broad and apical branch greatly reduced; marginal spot absent or divided into 1-3 small spots; basal band reduced into large spot from M to anal margin; basal spot absent. Hindwing similar to forewing, but with relatively reduced markings. Marginal spot absent or faint; basal band smaller, usually not reaching anal margin. Abdomen (Fig. 23A, D View Figure 23 ): T2-T5 dark to black brown. Notal organ of T3 flat, covering acute postnotal organ on T4. A6 dark brown on basal two-thirds and yellow distally, projected on dorsal apex, with sparse long yellow setae. A7 and A8 elongate, uniformly yellow, constricted basally. Genitalia (Fig. 23E-G View Figure 23 ): Genital bulb oval, yellow. Epandrium broad basally, with square, deep terminal emargination, bearing dense setae distally. Cercus long clavate, slightly expanded towards apex. Hypandrium with shortened basal stalk, with pair of long strip-like hypovalves; each hypovalve rounded at apex, bearing long bristles along apical half on inner margin, not reaching apex of gonocoxites. Inner margin of gonocoxite oblique apically, with 6-8 stout setae. Gonostylus with large basal cup and obtuse triangular median tooth on inner margin. Parameres twisted in S-shape, crossed mesally, bearing dense short spines on inner margin and whole distal portion, with apex pointed. Aedeagus with ventral valves greatly shortened; dorsal valves greatly elongated, strongly curved dorsally, constricted basally and expanded towards rounded apex; bearing bundle of long hairs ventrally on basal third and enlarged dorsal process near middle. Lateral process distinctly triangular. - Female: Similar to male in wing patterns (Fig. 23B View Figure 23 ). Genitalia (Fig. 23H-K View Figure 23 ): Subgenital plate broad subbasally, narrowed towards apex, bearing long setae on caudal and lateral margins. Medigynium with broad main plate, pair of lateral basal plates on middle portion; posterior arms one-third as long as length of main plate, forming "water drop"-shaped emargination; axis with pair of small sclerotized structures near central position of main plate, extended beyond main plate for approximately half of its length, with posterior slightly extruded.

Distribution.

China: Anhui.

Remarks.

This new species resembles P. huayuani and P. sexspinosa in general appearance, but can be readily differentiated from the latter two species by the following characters: (1) wing markings with basal band reduced into a large spot extending from M to anal margin in forewing (cf. complete); (2) occiput dark brown (cf. yellowish brown).
