FIGURE 1. R. aleutensis n. sp. (A–C) Ventral, ventrolateral, and lateral views of genital segments of whole worm, showing pores and claspers. The specimen was highly contracted, somewhat obscuring the secondary annulation. (D) Chaetae, from left to right: two ventral chaetae (segments VIII and XX) from a Finger Creek specimen, two ventral chaetae (VI and XII) and a pair (XXX) from a Little Thumb Creek specimen. (E–F) Transverse views of VIII, showing spermathecae joining the gut; and X, showing male pores and ectal part of atria; reconstructed from sections. No accessory glands were visible at the spermathecal pores of this specimen. (G) Sagittal view of atrium, from a dissection. Arrow indicates beginning of prostate glands (glands omitted in part for clarity). One of the vasa deferentia is embedded in the atrial muscle near the ental end; the other could not be followed in this specimen. Scale bars 100 m (D), 400 m (E–F).
