Abstract

A new hemichordate species, Protoglossus graveolens, is described from Maine, U.S.A. Protoglossus graveolens is the second member of its genus and the only North American protoglossid. Protoglossus graveolens occurs intertidally, usually with another enteropneust, Saccoglossus bromophenolosus King et al., 1994. The new species is assigned to the genus Protoglossus based on the following criteria: 1) proboscis musculature; 2) proboscis coelom; 3) proboscis septa; 4) a basal sheath at the posterior end of the proboscis stalk; 5) inclination of the collar; 6) perihaemal spaces in the collar; 7) lack of esophageal pores. Protoglossus graveolens is differentiated from Protoglossus koehleri (Caullery & Mesnil, 1900) on the basis of size, coloration, proboscis and branchial skeleton morphologies, collar dimensions and intemal organization of the collar.
