Type species - Limnobia ferruginea Meigen, 1818 , by subsequent designation of Coquillett, 1910 (Palaearctic).

Adult.

Medium-sized crane flies. Korean species with body length 4.5-9.0 mm ( Fig. 2A ) and wing length 5.8-9.5 mm. Body coloration varies from yellow to gray or brown.

Head: Apical antennomere small to very small, distinctly shorter than preceding segment.

Thorax: Prescutum and presutural scutum with indistinct longitudinal stripes or stripes completely missing. Wing iridescent, long and narrow, posterior margin evenly rounded, without angulate extension. Wing with dark- er areas surrounding base of Rs, at cord and along distal margin of discal cell. Apex of Sc and sc -r close to branching point of Rs. Radial sector usually long, longer than stem of cell r 3 or vein R 2+3, only as an exception, radial sector short, like in type species P. ferruginea , or Kore- an species P. melanommata . Anal vein slightly sinuous, reaching wing margin before level of Rs base.

Abdomen: Epandrium wider than long. Gonocoxite usually with ventro-mesal lobe at base. Apex of outer gonostylus usually simple, bifid in some species. Inner gonostylus fleshy and setose, wider at base, narrower at apex. One pair of parameres. Aedeagus simple, not branched, slightly arched and tube-shaped, apex curved upwards. Ovipositor with long, slightly arched cercus, hypovalva wedge-shaped with long parallel setae along dorsal margin.

Subgenus has only Palaearctic distribution. It includes 21 extant species, 16 of which occur in Eastern and 10 in Western Palaearctic ( Oosterbroek, 2021). No fossil species are ascribed to this subgenus ( Evenhuis, 2014).

Larva and pupa generally as in the characters of the genus mentioned above.
