species. Examination of many collections showed that C. bicrenata's 

 range extends from northern Alabama to north central Tennessee. In 

 northern Tennessee and southern Kentucky C. whitei occurs, continuing 

 north to Hart County, Kentucky, and west into southern Illinois. The 

 only substantial morphological difference between C. bicrenata and C. 

 whitei is the shape and placement of the lateral process of the male 

 second pleopod endopod tip. Although this difference in morphology is 

 consistent, other distinguishing characteristics are too variable to be 

 reliable. Furthermore, significant dispersal barriers that might provide 

 reproductive isolation do not appear to exist along the boundary 

 between the ranges of C. whitei and C. bicrenata. 



Caecidotea meisterae is herein synonymized with Caecidotea 

 whitei, and C. whitei reduced to a subspecies of Caecidotea bicrenata. 

 The rest of the taxonomy proposed by Lewis and Bowman (1981) for 

 other "alabamensis" species, i.e., Caecidotea antricola, C. beattyi and C. 

 jordani, remains unchanged.
