Taxonomic CommentsFormerly undescribed from southwest Oregon (see Frest and Johannes, 2000). Identified in Frest and Johannes (2000) as Fluminicola n. sp. 13. Recently described by Hershler et al. (2007) as Fluminicola warnerensis.
Ecology & Habitat
Diagnostic Characteristics
Differs from similar F. turbiniformis in its larger size (SH, SW, P = 0), darker body pigment, less prominent sperm storage area in the coiled oviduct, complete overlap of the seminal receptacle by the albumen gland, broader bursa copulatrix, absence of a seminal receptacle duct, and frequent occurrence of a papilla-like capsule gland opening. Distinguished from geographically proximal F. erosus and F. lunsfordensis by its more elongate shell, more convex shell whorls, single basal cusp of the central radular tooth, and enlarged large central cusp of the lateral radular tooth. Also differs from the former in its larger size and from the latter by its weakly angled adapical portion of the aperture (Hershler et al., 2007).
