On a new and puzzling American rotifer (Rotifera: Monogononta, Lecanidae)

Abstract

A new species of monogonont rotifer, Lecane difficilis n.sp., is described from French Guyana. The taxon also occurs in Brazil and North Carolina, USA, following reassessment of illustrated literature records. The superficial similarity of L. difficilis with the Old World tropical L. unguitata (Fadeew) may account for some non-verifiable records of the latter from the New world.
