Malacobdella arrokeana (Nemertea: Bdellonemertea), a new species of nemertean from the Southwestern Atlantic Ocean entocommensal in Panopea abbreviata (Bivalvia, Heterodonta, Hiatellidae) in Argentina

Malacobdella arrokeana, a new species of entocommensal nemertean is described from the mantle cavity of the bivalve Panopea abbreviata in Argentine waters. This discovery expands the distribution of the genus, including the Southern Hemisphere for the first time, and represents a new host record. Ma...
