Type species: Pelastoneurus arcuatus Loew, 1861 (subsequent designation by Coquillett, 1910: 583 ). Leptocorypha Aldrich, 1896: 315 . Type species: Leptocorypha pavo Aldrich, 1896 (monotypy). Synonymized by Robinson (1970: 47) . According to Brooks (2005) , the broad concept of Paraclius can be recognized by the following combination of characters: arista-like stylus bare to strongly pubescent, not plumose; clypeus flat or weakly pronounced, distinctly shorter than face in males, not exceeding lower margin of eyes; wing vein M 1 bent beyond crossvein dm-m; mid and hind femora usually with one preapical seta. Outside of the lineage of species related to P. arcuatus (Loew) , the type species of Paraclius , a meaningful generic concept for the species currently included in Paraclius based on synapomorphies is still pending, and the genus is presently better seen as a holding taxon, like Hercostomus ( Brooks 2005 ) .
