Genus HERCOSTOMUS Loew, 1857a

HERCOSTOMUS Loew, 1857a: 9 . Type species: Sybistroma longiventris Loew [Palearctic], by original designation.

DASYARTHRUS Mik, 1878b: 5 . Type species: Gymnopternus inornatus Loew , by original designation.

MICROHERCOSTOMUS Stackelberg, 1949: 687 (as subgenus). Type species: Hercostomus (Microhercostomus) dilatitarsis Stackelberg , by original designation. Synonymized by Grichanov (1997a).

AHERCOSTOMUS Yang & Saigusa, 2001a: 239 (as subgenus). Type species: Hercostomus (Ahercostomus) jiangchenganus Yang & Saigusa , by original designation.

NOTES: Hercostomus is known from all realms; however, this genus is clearly polyphyletic and its limits should be redefined. It reaches its highest diversity in the Palearctic, especially in the southeast. Representatives are found in a wide variety of habitats, ranging from coastal dunes to humid forests and springs.
