GENUS HAUSTORIUS MÜLLER, 1775

Type species: Haustorius arenarius Slabber, 1769 .

Diagnosis: Large haustoriids (5–16 mm). Maxilla 2 outer lobe narrow and lanceolate, more than twice size of inner lobe. Pleon overhanging urosome; epimeron 3 smooth, ventrally curved (without hook). Telson cleft emarginate.

Known species: Haustorius algeriensis Mulot, 1968 ; H. arenarius Slabber, 1769 ; H. canadensis Bousfield, 1962 ; H. mexicanus Ortiz et al., 2001 *; H. orientalis Belan-Santini, 2005 .

*The status of H. mexicanus is unclear. If a true Haustorius (in our definition above), it would represent the only Haustorius in the GoM. However, we have been unable to obtain specimens of this species and have not located it at its type locality.

Range: Restricted to open coasts in the Atlantic and Mediterranean.
