| Abstract |
Two new species of the genus Promesostoma, P. infundibutum nov. spec. and P. hymanae nov. spec., are described from the mesopsammal of the San Juan Archipel (Washington, USA). They are closely related to P. dipterostylum Karling from the Californian coast. These three species have a differentiated seminal receptacle with special cuticular structures, which represents a remarkable synapomorphy. The cuticular connection between the styler and the seminal receptacle was unknown untill now in the organization of turbellarians. |
