Syntormon is a genus of flies in the family Dolichopodidae.

It includes about 110 species worldwide, more than 50 of which were described from the Palaearctic realm.

[3] The name Syntormon is derived from the Ancient Greek word συντορμόω (syntormóō, "I connect by inserted pins"); it refers to the second segment of the antennae which has a small thumb-shaped projection going into the inner side of the third segment, appearing as if it were a pin inserted into a socket.

[1][4][5] The following species are included in the genus:[note 1] Subgenus Syntormon Loew, 1857: Subgenus Drymonoeca Becker, 1907: Unrecognised species: Synonyms: Syntormon guizhouensis Wang & Yang, 2006[13] is an unavailable name, as it does not satisfy ICZN Articles 16.1 and 16.4: the original publication does not explicitly indicate the name to be intentionally new, and the fixation of name-bearing types for the species is not explicit.
