Pseudopelmatops indiaensis Chen View in CoL sp. nov.

( Figs. 7 View FIGURES 1–9 , 16 View FIGURES 10–17 , 23 View FIGURES 18–25 , 31 View FIGURES 26–33 )

Diagnosis. This species is readily differentiated from other Pseudopelmatops by wing with broad brownishblack costal band and a narrow brownish-black crossband extending from crossvein R-M to middle of cell cu 1 and connect to the costal band anteriorly, and palpus covered with fine, yellow setulae.

Description. Wing length 10.5–13.0 mm (abdomen missing). The whole body usually predominantly dark brown to black and sub-shining ( Fig. 7 View FIGURES 1–9 ).

Head ( Figs. 16 View FIGURES 10–17 , 23 View FIGURES 18–25 ): dark brown to black except the middle of frons with a very narrow yellow longitudinal stripe; the ventral 1/2 of face, parafacial and palpus yellow to yellow-brown. Palpus spatulate, sparsely covered with fine, yellow 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, dorsoapically rounded; arista plumose, longest ray slightly shorter or about equal to width of 1 st flagellomere.

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

Wing ( Fig. 31 View FIGURES 26–33 ). Largely hyaline with broad brownish-black costal band extending from the base of cell r 1 to the wing tip (posterior margin of costal band partly in cells br and r 4+5), and a narrow brownish-black crossband extending from crossvein R-M to middle of cu 1 and connect to the costal band anteriorly; pterostigma yellow-brown, narrow and long, about 0.90 times as long as cell c. Vein R 4+5 setose from base to crossvein R-M.

Legs. Coxa, trochanter and basal 3/5 of femora dark brown, other parts yellow; slender and long.

Abdomen missing (a label “ ♀ ”pinned under the specimen. The first author has observed the abdomen kept on a slide separately. However, the slide missed lately because of transportation).

Male. Unknown.

Distribution. India (Ranikhet).

Type data. Holotype ♀ ( BPBM), India: Ranikhet , 22 June 1949, I. M. Newell.

Etymology. This species is named after the type locality.

Remark. The wing pattern of this species is distinctive. It has a broad brownish-black costal band that is similar to that of Ps. continentalis Zia & Chen , and a narrow brownish-black crossband extending from crossvein R-M to middle of cu 1 and connect to the costal band anteriorly that similar to Ps. angustifasciatus Zia & Chen. The palpus of this species is sparsely covered with fine, yellow setulae which more like Pelmatops species than Pseudopelmatops .

Pseudopelmatops nigricostalis Shiraki, 1933

( Figs. 8 View FIGURES 1–9 , 32 View FIGURES 26–33 )

Pseudopelmatops nigricostalis Shiraki, 1933: 51 View in CoL . Type-locality: Arisan, Taiwan. Syntypes (2 males) in NTU. — Zia & Chen, 1954: 309. — Hardy, 1977: 77. — Wang, 1996: 113.

Diagnosis. This species differs from other congeners by the presence of 1 pair of frontal setae and 1 postalar seta in combination with entirely black femora.

Redescription. Body length 12mm; wing length 11.5mm. The body usually predominantly black and subshining ( Fig. 8 View FIGURES 1–9 ).

Head: Black except the middle of frons with a very narrow reddish longitudinal stripe, face with a narrow ill-defined grayish-yellow transverse band just dorsal to ventral margin, yellowish lunula and palpus, and reddish-yellow proboscis. Palpus narrow, parallel-sided and densely covered with strong, black setulae. Chaetotaxy reduced: head with orbital, frontal, medial vertical and genal setae present; postocellar, lateral vertical, and ocellar absent. Antenna distinctly longer than face, 1 st flagellomere 1/4–1/3 as wide as long, dorsoapically rounded; arista plumose, longest ray slightly shorter or about equal to width of 1 st flagellomere.

Thorax entirely dark brown to black except 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. 32 View FIGURES 26–33 ). Largely hyaline with broad brownish-black costal band extending from the base of cell r 1 to the wing tip (posterior margin of costal band partly in cells br and r 4+5); pterostigma yellow-brown, narrow and long, about as long as cell c. Halter yellow.

Legs. Slender and long,with the tibiae and tarsi reddish-brown, femora entirely black,.

Abdomen brown and elongate; tergites 1–2 nearly parallel-sided

Female. Unknown.

Distribution. China (Taiwan).

Type data. Syntypes 2♂ (Entomological Museum of the Government Research Institute, Taihoku, Formosa), CHINA: Taiwan : Arisan, Vll, X. (not examined) .

Remark. The redescription of this species is based on the original description ( Shiraki, 1933). We were unable to borrow the syntypes.
