Type species: Limnophila brevifurca Osten Sacken, 1860 ( North America ) .

Adult.

Small crane flies with body length 5.8-7.3 mm and wing length 7.1-8.2 mm. Body coloration varies from gray or bluish-gray to brown.

Head: Vertex with small tubercle. Head broadly round- ed posteriorly. Antennal flagellum 14-segmented. Verticils exceeding length of respective segments.

Thorax: Pronotum large. Mesonotal prescutum with small but distinct and separate tubercular pits at frontal margin. Pseudosutural fovea large. Wing setoseless, usually without pattern, sometimes with brownish spots at cord and at base of Rs ( D. adjuncta ( Walker, 1848)) . Stigma light, setoseless. Vein Sc long, reaching distinctly beyond branching point of Rs, sc-r at or slightly beyond branching point of Rs, cell r 3 without additional cross-vein, discal cell always present, cell m 1 very small, missing in some specimens, anal vein nearly straight, anal cell long and narrow with widely rounded posterior margin. Wing squama setoseless.

Abdomen: Abdominal tergites with paired transverse sutures. Male terminalia: ninth tergite wider than longer, posterior margin nearly straight, gonocoxite elongate with large interbase and without ventro-mesal lobe. Two pairs of gonostyli. Outer gonostylus long and slender, sclerotized, smooth, shortly bidentate at apex. Inner gonostylus elongate, fleshy and setose. Interbase spoon-shaped. Parameres separate. Aedeagus simple, straight elongate tube.

Subgenus includes 13 species worldwide and has Holarctic and Oriental distribution. Five species recorded from East Palearctic, five from West Palearctic, four from Oriental and two from Nearctic Regions ( Oosterbroek, 2020), no fossil species ( Evenhuis, 2014).

Larva. As described for the genus, except frons, which is reduced to a trapezoidal plate and abdominal segments VI- VII having ventral creeping welts.

Pupa. As described for the genus.
