Rs is relatively long and cell m1 is petiolate. Tip of eighth sternite has long dense thick setae. Ninth tergite has a U-shaped depression. Lobe of gonostylus is subtriangular and posterior margin has a shallow V-shaped incision with a black sclerotized protuberance. Clasper of gonostylus is small and beak-like.

Head (Figs 38 View Figures 38–43 , 39 View Figures 38–43 ). Mostly brownish yellow. Dorsal part of rostrum brownish yellow, with distinct long nasus. Eyes black. Setae on head black. Antenna dark brown except scape brownish and pedicel yellow; first flagellomere longest, slightly longer than scape. Proboscis mostly brown with black setae; palpus greyish brown, with black setae.

Thorax (Figs 38 View Figures 38–43 , 39 View Figures 38–43 ). Mainly brownish. Pronotum yellow with a light brown spot at middle. Prescutum yellow with three brown stripes; median stripe narrowed basally with a light brown median line; lateral stripes oval, a little shorter than median stripe. Scutum yellow, each lobe with a brown stripe. Scutellum yellow with a brown margin. Mediotergite yellow with a brown area near hind margin. Pleuron brownish yellow. Setae on thorax brownish yellow. Legs with coxae and trochanters yellow; femora light brown with dark tips; tibiae and tarsi dark brown. Setae on legs black, except those on coxae yellow. Wings light brown; pterostigma dark brown with some macrotrichia; posterior margin of cell cua1 as wide as base; Rs relatively long, cell m1 petiolate (Fig. 40 View Figures 38–43 ). Halter length approximately 2.5 mm; halter stem pale yellow; halter knob brownish gray, with brownish setae.

Abdomen (Fig. 38 View Figures 38–43 ). Mainly brownish yellow. Abdominal segments 1-5 brownish yellow with yellow setae; remaining segments dark brown with light brown setae.

Hypopygium (Figs 44-48 View Figures 44–48 ). Eighth sternite with dense long thick setae at tip. Ninth sternite sclerotized, convex. Ninth tergite with a U-shaped depression, laterally with yellow setae. Hypopygium mostly brownish yellow, lobe of gonostylus triangular, slightly curved, broadened apically, posterior margin with shallow V-shaped incision and with black sclerotized protuberance. Clasper of gonostylus small, beak-like.

Semen pump (Figs 41-43 View Figures 38–43 ). Posterior immovable apodeme (pia) brownish yellow, rod-like, and directed backward. Compressor apodeme (ca) ginkgo-leaf-shaped and directed ventrally. Anterior immovable apodeme (aia) triangular.

Tipula (unplaced) cladomera was proposed by Alexander (1936a, as T. (Oreomyza) cladomera )) and some morphological differences were indicated. According to Alexander (1936a), males of T. (unplaced) cladomera are characterized by the following features: hypopygium with the lobe of gonostylus very large and of unusual shape, expanded outwardly, the apex with a U-shaped notch which forms two conspicuous lobes; eighth sternite with nine or ten very coarse setae on either side of midline of the caudal margin (Fig. 51 View Figures 49–52 ; Alexander 1936a: 230; pl. 2, figs 25, 26). After comparison of the type specimens of T. (unplaced) cladomera Alexander, 1936 with T. (Vestiplex) reposita Walker, 1848 and our specimens from Laos, we found that those specimens do not have clear differences and are characterized by the same features, even though the males of T. (unplaced) cladomera have no shorter cross-vein between cell dm and cell cua1 (Fig. 50 View Figures 49–52 ; Alexander 1936a: pl. 1, fig. 5), and T. (Vestiplex) reposita does have shorter cross-vein between cell dm and cell cua1 (Brunetti in Joseph 1974: 268, fig. 109). Altogether, through examining many specimens, including holotypes and paratypes, and the literature, we attribute such differences as intraspecific variation and consider these two species to be the same and T. (O.) cladomera to be a junior synonym of T. (unplaced) reposita . This species used to be placed in the Tipula subgenus Vestiplex , although in our opinion, such an arrangement is incorrect because of the unique male genital complex. Tipula (unplaced) reposita Walker, 1848 does not belong to any existing subgenus and is to be considered unplaced.
