Hydatostega plumbea
Hydatostega plumbea is a species of long-legged fly in the family Dolichopodidae, described by Aldrich in 1911. It belongs to the subfamily Hydrophorinae, a group of predatory flies often associated with aquatic or semi-aquatic habitats. The genus Hydatostega is characterized by species with hydrophilous tendencies. Information on this species remains sparse, with only 5 observations recorded on iNaturalist as of the available data.
Hypocharassus
Hypocharassus is a genus of long-legged flies (Dolichopodidae) comprising five described species distributed across the Nearctic, Oriental, and Palearctic regions. The genus is the sole member of the tribe Hypocharassini within subfamily Hydrophorinae. Species are associated with marine and coastal habitats, with adults flying low over wet sand and larvae inhabiting intertidal zones. The Korean species H. cavitarsus represents the first Palearctic record, expanding the genus's known range.
Liancalus genualis
Liancalus genualis is a species of long-legged fly in the family Dolichopodidae, notable as the only member of its genus known from eastern North America. Like other dolichopodids, it is a predatory fly. The species was described by Loew in 1861.
Liancalus limbatus
Liancalus limbatus is a species of long-legged fly in the family Dolichopodidae, described by Van Duzee in 1917. The genus Liancalus belongs to the subfamily Hydrophorinae, a group associated with aquatic and semi-aquatic habitats. Like other dolichopodids, members of this genus are predatory as adults. The specific epithet "limbatus" refers to a bordered or edged characteristic, though the precise morphological basis for this name is not documented in available sources.
Liancalus querulus
Liancalus querulus is a species of long-legged fly in the family Dolichopodidae, first described by Osten Sacken in 1877. As a member of this large and diverse family, it shares the characteristic elongated legs and metallic coloration typical of dolichopodids. The genus Liancalus includes species associated with moist habitats, though specific details for L. querulus remain limited in available sources.
Scellus virago
Scellus virago is a species of long-legged fly in the family Dolichopodidae, first described by Aldrich in 1907. Members of this genus are associated with aquatic or semi-aquatic habitats. As with other Dolichopodidae, adults are predatory. The species is known from limited observational records.
