Wang, Ji-Shen & Gong, You-Jing, 2021, Taxonomy of the Panorpaguttata group (Mecoptera: Panorpidae), withdescriptions of fourteen new species from China, Zootaxa 4981 (2), pp. 241-274 : 254-255

Panorpa hirundo Wang , sp. n.

( Fig. 9 )

Etymology. The specific epithet hirundo , meaning swallow in Latin, refers to the male A6 of this species being swallow tail-shaped at the dorsal apex. Noun in apposition.

Diagnosis. The new species is peculiar by the combination of the following characters: 1) wings devoid of markings; in males, 2) A6 with deep arcuate emargination and forming pair of triangular lobes laterally at dorsal apex; 3) parameres bifurcated with ventral branch long and stout, greatly enlarged subapically with pointed apex; and in females, 4) medigynium with main plate nearly diamond-shaped and broadest at middle.

Type series. CHINA: Sichuan: Holotype ♂ (CN20Pa00104), Mt. Emei , 3000 m, 29°31’33’’ N 103°20’03’’ E, 25.vii.2020, leg. Dan-Chen Zhu; paratypes 6♂ 3♀ (CN20Pa00105– CN20Pa00113), same data.

Measurements. Male: AtL 10.0– 10.4 mm, AbL 7.6–8.2 mm, BL 10.0–11.0 mm, FL 11.6–12.0 mm, FW 2.5–2.6 mm, HL 10.5–11.0 mm, HW 2.5–2.6 mm; Female: AbL 6.2–7.2 mm, BL 10.0– 12.6 mm, FL 11.5–12.4 mm, FW 2.5–2.7 mm, HL 10.2–11.3 mm, HW 2.4–2.6 mm.

Description-male. Head. Vertex, occiput and rostrum yellowish brown, ocellar triangle black.

Wings. Membrane hyaline, tinged with yellowish brown, and devoid of markings. Forewing 1A ending approximately at same level with ORs; and two cross-veins between 1A and 2A. Hindwings similar to forewings.

Abdomen. T1–T5 yellowish brown to dark brown, with pale, continuous median stripe extending from T1 to T5. A6 yellowish brown, cylindrical, with deep arcuate emargination on dorsal apex, and forming pair of triangular lobes laterally. A7 and A8 yellowish brown, A7 nearly cylindrical and slightly humped on dorsal apex, A8 constricted basally and beveled apically.

Male genitalia. Genital bulb yellowish brown, oval. Epandrium extending beyond middle of gonostylus, slightly tapering towards apex, with deep U-shaped terminal emargination and forming two parallel finger-like processes. Hypandrium Y-shaped and approximately 7/8 as long as gonocoxites, with greatly reduced basal stalk shorter than 1/5 length of hypovalves. Hypovalves narrow, divergent in basal half and nearly parallel in distal half, with sparse long bristles along inner margin. Gonostyli shorter than half length of gonocoxites, with broad disc-shaped basal lobe and subtriangular median tooth. Parameres furcated into two slender and glabrous branches; ventral branch long and stout, slightly curved inwards apically, greatly enlarged subapically with pointed apex; dorsal branch thinner and shorter, approximately 4/5 as long as ventral branch and lesser enlarged subapically. Ventral aedeagal valves membranous, rounded, and covered with numerous microtrichia; dorsal processes slender, greatly elongated, nearly parallel, and tapering to subacute apex in distal 1/4.

Description-female. Similar to males in general appearance except for darker terga.

Female genitalia. Subgenital plate broadest at middle with slightly emarginated apex and sparse long setae on distal margin. Medigynium with broad main plate approximately half as long as axis and widest at middle; posterior arms very thin, approximately 1/2 as long as main plate; apodemes of axis thick, greatly divergent at base.

Distribution. CHINA: Sichuan: Mt. Emei ( Fig. 2 ).
