Etymology: Crystallaria: Latin, cristallum = ice (Ref. 45335); cincotta: Named for Daniel A. Cincotta, for his devotion toward studies of fish diversity of West Virginia, including efforts toward conservation of the Elk River drainage and its diverse ichthyofauna..
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic. Temperate
North America: Cumberland, Elk, Green and Muskingum river drainages of the Ohio River basin, USA. Known only to be extant in the Elk River, West Virginia.

Morphology | Morphometrics
(total): 11 - 13;
soft rays: 11 - 13. Distinguished from populations of Crystallaria asprella of the Gulf Coast, Mississippi River and Wabash River by a combination of the following features: gape width larger approximately equal to or exceeding the inter-pelvic fin base width; a preorbital blotch distinctly separate from the anterior orbital rim; pelvic fins distinctly falcate in both sexes; cheek scale rows reduced (modally 2); opercle scale rows reduced (modally 2); number of midlateral blotches higher (modally 13); number of anal-fin rays lower (modally 13); number of dorsal-fin spines lower (modally 12); and scales below the lateral line higher (modally 11) (Ref. 74948).
Found mostly in waters with moderate flows over a sand, gravel and cobble mix of benthic substrate within the lower sections of riffles or upper parts of pools (Ref. 75199).
