Genus SCELLUS Loew, 1857a

SCELLUS Loew, 1857a: 22 . Type species: Hydrophorus spinimanus Zetterstedt [Palearctic, Nearctic], designation by Coquillett, 1910c: 603.

ANOPLOMERUS Rondani , error, see Ulrich (1972) and Hurley (1995).

ANOPLOPUS Rondani , error, see Ulrich (1972) and Hurley (1995).

NOTES: Scellus is restricted to the Holarctic realm. In the Nearctic, most species are western, except for the widespead species S. exustus . Adults have been collected in swampy, high­mountain meadows, pastures on the plains, and on the bark of trees ( Hurley, 1995).

Genus THAMBEMYIA Oldroyd, 1956

THAMBEMYIA Oldroyd, 1956: 210 . Type species: Thambemyia pagdeni Oldroyd [Oriental], by original designation.

CONCHOPUS Takagi, 1965: 49 . Type species: Conchopus rectus Takagi , by original designation. Synonymized by Meuffels & Grootaert (1984). Listed by Bickel & Dyte (1989).

PARAPHROSYLUS , authors, not Becker, 1922a, misid, listed by Bickel & Dyte (1989).

NOTES: Thambemyia is known from the

Palearctic and Oriental realms and Hawaiian

Islands, but most of the species have been described from coastal Japan ( Takagi, 1965). Like Paraphrosylus , species of Thambemyia live exclusively in the intertidal zone of rocky seashores or coral reefs. The predaceous larvae live among barnacles in the littoral zone and pupate in the valves of dead barnacles ( Sunose & Satô, 1994a, 1994b). Thambemyia borealis was probably introduced into North America by human­assisted dispersal, taking into account its recent discovery and its disjunct distribution in the Nearctic ( Masunaga et al. 1999).

Genus THINOPHILUS Wahlberg, 1844

THINOPHILUS Wahlberg, 1844: 37 . Type species: Rhaphium flavipalpe Zetterstedt [Palearctic, Afrotropical], by monotypy.

THINOPHILUS Schiødte, 1844: 44 . Type species: Rhaphium flavipalpe Zetterstedt , by monotypy; preocc. by Thinophilus Wahlberg, 1844 .

NOTES: Thinophilus is known from all realms and is found mostly in coastal habitats such as shores and saltmarshes. In contrast to Paraphrosylus and Thambemyia , Thinophilus species are mainly found on wet sand or muddy substrates.
