V.E. Pilipenko & P. Starkevich. A new species of Tipulidae from Nepal brownish with tips dark brown. Tibiae and tarsal segments dark brown. Tarsal claws with a tooth. Wing pale brown, sparsely variegated by darker brown and whitish subhyaline areas. Abdominal segments 1–4 yellow; segments 5–9 brown to dark brown. Tergites with posterior margins narrowly pale, dorsally with brown median stripe and narrow lateral streak.

Hypopygium ( Fig. 4A–K). Hypopygium dark brown. Dorsal surface of tergite 9 covered with setae, its posterior margin with two finger-shaped lobes directed caudally and provided with abundant setae ( Figs 4A, 4C). Ventral side of tergite 9 yellow, with a pair of blackened, microscopically roughened lobes ( Fig. 4D). Gonocoxite entirely cut off from sternite 9, apically produced into two spines ( Figs 4B, 4E); outer spine slender, brownish-black, slightly curved, with subacute tip; inner spine shorter, yellowish with blackened obtuse tip. Outer gonostylus narrow, elongate, finger-shaped ( Fig. 4F). Inner gonostylus elongate, brownish yellow ( Figs 4G, 4H). Upper beak short and obtuse; lower beak in shape of black narrow lobe, dorsal crest with margin sloping, basally expand- ed into hump. Medial surface beneath the lower beak with a short medially broadened lobe having a blackened edge ( Fig. 4G). Sternite 9 with ventral lobe of A9S nearly triangular with rounded tip, covered with setae ( Fig. 4B). Dorsal lobe of A9S elongate, gently curved, with narrowed and blackened tip ( Figs 4B, 4I). Adminiculum triangular in ventral view, basally broad, apically extended, with acute tip ( Fig. 4B). Sperm pump with central vesicle swollen ( Fig. 4J). Compressor apodeme with a broad and deep median incision ( Fig. 4K). Posterior immovable apodeme narrow. Anterior immovable apodeme in shape of round- ed plate. Aedeagus yellow, about 3.3 times as long as sperm pump ( Fig. 4J). Distal part of aedeagus funnel-shaped, with two rounded microscopic formations; margin with short triangular tip.

Female. Body length 21.2 mm, wing length 19.1 mm (n = 1). Generally similar to male. Antenna short, if bent backward reaching prescutum.
