Polyderis laeva (Say, 1823)

Bembidium laevum Say, 1823a: 88. Type locality: "Arlington [Middlesex County], Mass[achusetts]" (neotype label). Neotype (♀), designated by Lindroth and Freitag (1969: 339), in MCZ [# 33057]. Note. Because Say (1823a: 88) used the epithet laevum with the generic name Bembidium , the specific name derives from the Latin adjective laevus, - a, - um (left, clumsy [figurative]), not from the Latin adjective laevis, - e (smooth). Therefore, used with the feminine generic name Polyderis , the specific name is laeva, not laevis as used by modern authors.
