Pseudopelmatops continentalis Zia & Chen View in CoL

( Figs. 6 View FIGURES 1–9 , 15 View FIGURES 10–17 , 25 View FIGURES 18–25 , 30 View FIGURES 26–33 , 39, 42 View FIGURES 34–42 , 47 View FIGURES )

Pseudopelmatops nigricostalis continentalis Zia & Chen, 1954: 310 View in CoL . Type-locality: Tianmushan, Zhejiang; Chongan [not Shao-Woo as originally recorded by Zia & Chen (1954)], Fujian, China. Lectotype male and three paralectotypes designated by Wang, 1996 in IZCAS. — Hardy, 1977: 76. — Wang, 1996: 112.

Diagnosis. This species is similar to P. nigricostalis Shiraki in wing markings, but differs by lacking frontal and postsutural supra-alar setae; and femora yellow except the basal 1/2–3/5 dark brown. It also closely resembles P. angustifasciatus in body coloration and chaetotaxy of the head and thorax, but is easily distinguished by having a much broader brownish-black costal band extending proximally to the base of cell r 1 ( Fig. 30 View FIGURES 26–33 ).

Description. Body length 13.5–16.0 mm; wing length 10.5–13.0 mm. The body usually predominantly dark brown to black and sub-shining ( Fig. 6 View FIGURES 1–9 ).

Head ( Figs. 15 View FIGURES 10–17 , 25 View FIGURES 18–25 ): dark brown to black except the middle of frons with a very narrow yellow longitudinal stripe; ventral 1/2 of face, parafacial and palpus yellow to yellow-brown. Palpus narrow, parallelsided and densely covered with strong, black setulae. Chaetotaxy reduced: head with orbital, medial vertical and genal setae present; postocellar, lateral vertical, ocellar, and frontal setae absent. Antenna almost equal to face, with 1 st flagellomere about 1/4–1/3 as wide as long, and 1 st flagellomere dorsoapically slightly sharp; arista plumose, longest ray slightly shorter or about equal to width of 1 st flagellomere.

Thorax entirely dark brown to black except for scutum with two slightly broad grayish-white microtrichose longitudinal stripes, halter yellow. Chaetotaxy reduced: only 1 notopleural, 1 postalar and 1 apical scutellar setae present.

Wing ( Fig. 30 View FIGURES 26–33 ). Largely hyaline with a broad brownish-black costal band extending from the base of cell r 1 to the wing tip, all the posterior margin in the cells br and r 4+5; pterostigma yellow-brown, narrow and long, about 0.97–1.00 times as long as cell c. Vein R 4+5 bare.

Legs. Slender and long. Coxa, trochanter and the basal 2/3 of femora dark brown, other parts yellow brown.

Abdomen elongate with tergites yellow-brown to dark brown; tergites 1–2 combined nearly parallel-sided and almost as long as tergites 3 and 4 combined.

Male terminalia: Epandrium large and broad, rounded in posterior view ( Fig. 39 View FIGURES 34–42 ); lateral surstylus small and short, apex rounded in lateral view ( Fig. 42 View FIGURES 34–42 ); medial surstylus with 1 black prensiseta. Glans slightly expanded medially, without distinct acrophallus and membranous subapical lobe ( Fig. 47 View FIGURES ).

Female. Unknown.

Distribution. China (Hunan, Hubei, Zhejiang, Fujian, Sichuan, Yunnan). Hunan and Hubei are new province records for this species.

Type data. Lectotype ♂ ( IZCAS), CHINA: Zhejiang: Tianmushan, 8. July 1936 (examined); paraletotypes: 1 ♂, same data with lectotype (examined); 1 ♂, same locality as lectotype, 20 July 1936 (examined); 1 ♂ ( IZCAS), CHINA: Fujian: Chongan , 24 July 1944 (examined).

Other specimens examined. CHINA: Hunan: Sangzhi , 1200m, 14 August 2001, J. Wen & N.T. Huang, 1 ♁ ( IZCAS) . Hubei: Shennongjia , 900m, 11 August 2004, Z. Wang, 1♁ ( IZCAS) . Sichuan: Mt. Emei , 27 July 1957, Y. C. Lu, 1♁ ( IZCAS) . Yunnan: Kunming , 1200 m, 7 July 1956, K. R. Huang, 1♁ ( IZCAS) .

Remark. The type specimens of Ps. angustifasciatus (females) and Ps. continentalis (males) were collected in the same days and locality. Considering sexually dimorphic of wing pattern in this group, a possibility that they are conspecific has been considered seriously. However, their unpublished DNA sequence data from author’s recent molecular experiment didn’t support this suppose so far.
