Diagnosis.
Abdomen is reddish brown with thick brownish yellow setae. Eighth sternite extended backward, posterior margin has a deep median notch. Posterior margin of ninth tergite extended with sclerotized depression. Lobe of gonostylus is fleshy with a V-shaped depression at posterior margin. Clasper of gonostylus is duck-shaped.
Description.
Male (n = 8): body length 20-23 mm, wing length 16-18 mm, antenna length 5-6 mm.
Head (Figs 19 View Figures 19–22 , 21 View Figures 19–22 ). Mostly brownish yellow. Dorsal part of rostrum brownish yellow; nasus blacked; eyes dark black. Setae on head black. Antenna dark brown, except scape brownish and pedicel yellow; first flagellomere longest, slightly longer than scape. Proboscis mostly brownish, with black setae. Palpus greyish brown, with black setae.
Thorax (Figs 19 View Figures 19–22 , 21 View Figures 19–22 ). Mainly brownish. Prescutum brownish yellow with three pale yellow stripes; median stripe broad basally with a light brown median line, lateral stripes oval, shorter than median stripe. Scutum brownish yellow, each lobe with two pale yellow stripes. Scutellum gray-yellow. Mediotergite yellow with long brownish yellow setae. Thoracic pleuron mostly brownish throughout, except middle of pleuron bright yellow or tinged brown. Setae on thorax brownish yellow. Legs coxae and trochanters grayish yellow, femora light brown, with subterminal dark band, tibiae, and tarsi brownish. Setae on legs black except those on coxae grayish yellow. Wings brownish yellow, with dark brown spots at the origin of Rs, M, and R4+5. Pterostigma dark brown with some macrotrichiae, Rs relatively long; cell m1 petiolate (Fig. 22 View Figures 19–22 ). Halter length approximately 2.5 mm; halter stem brownish yellow, with brownish yellow setae; halter knob pale yellow (Fig. 21 View Figures 19–22 ).
Abdomen (Fig. 19 View Figures 19–22 ). Mainly brownish yellow. Abdominal segments 1-6 brownish yellow with yellow setae; segments 7 and 8 with brown setae. Hypopygium reddish brown, with brown setae.
Hypopygium (Figs 19 View Figures 19–22 , 23-27 View Figures 23–27 ). Eighth sternite extended backward, posterior margin with a deep median notch and setae; two small, triangular processes present at bottom of notch. Posterior margin of ninth tergite extended with ossified depression; middle of extension with a small spiny protrusion. Ninth sternite with dark-brown setae laterally. Lobe of gonostylus fleshy with dense, dark-brown setae on outer side and dense, black, obtuse spinules on inner side, posterior margin with a V-shaped depression. Clasper of gonostylus duck-shaped; posterior crest with longer setae.
Semen pump (Figs 28-30 View Figures 28–33 ). Posterior immovable apodeme (pia) reddish brown, rod-like, and directed backward, symmetrical on both sides. Compressor apodeme (ca) fan-shaped and directed ventrally. Anterior immovable apodeme (aia) wing-shaped. Other appendages complex, as shown in Figures 28-30 View Figures 28–33 .
Female (n = 2): body length 22-23 mm, wing length 17-18 mm, antenna length 5-6 mm.
Female resembles male in head and thorax, except abdomen plump (Fig. 20 View Figures 19–22 ). Eighth tergite and eighth sternite reddish brown throughout. Ninth tergite, ninth sternite, and basal region of tenth tergite dark reddish brown (Figs 31-33 View Figures 28–33 ).
Ovipositor reddish brown (Figs 31-33 View Figures 28–33 ). Cercus narrowed toward tip. Hypovalve curved, broad apically.
Type material.
Holotype: male (CAU), Laos: Champasak, Soukhouma, Dond Hua Sao N. B., 2017.VI.19, Liang Wang (light trap). Paratypes: 2 males 2 females (CAU), Laos: Champasak, Sabaidee Valley, 2017.VI.16, Liang Wang (light trap); 5 males (CAU), Laos: Champasak, Soukhouma, Dond Hua Sao N. B., 2017.VI.19, Liang Wang (light trap).
Distribution.
Laos (Champasak).
Etymology.
The species is named after Champasak Province, where the type locality is located.
Remarks.
This new species is somewhat similar to T. (N.) coquilletti Enderlein, 1912 from Japan and T. (N.) sinica Alexander, 1935 from China (Zhejiang) in having a similarly shaped hypopygium, but it can be separated from these species by the shape of the eighth sternite and ninth tergite, posterior margin of eighth sternite with V-shaped notch which with two long triangular processes at bottom, and posterior margin of ninth tergite with a small spiny protrusion at middle. In T. (N.) coquilletti , the posterior margin of eighth sternite is without processes and V -shaped depression, and the posterior margin of the ninth tergite has a V-shaped notch. In T. (N.) sinica , the eighth sternite is without processes and V-shaped depression, and the posterior margin of the ninth tergite is extended with a sclerotized U-shaped depression.
