Eudontomyzon graecus is distinguished from its European congeners by possessing the following character states: nonparasitic mode of life; adults with large, blunt labial teeth covering all fields in a pavement-like arrangement; one or more bicuspid teeth in the first anterial row; two or more bicuspid teeth in the first posterial row; 7-11 teeth on the infraoral lamina; endolateral formula, 2-2-2; 2-5 velar tentacles without wings; ammocoetes and adults with 53-61 trunk myomeres; rounded caudal fin; relatively longer tail length against TL; ammocoetes with relatively shorter trunk length against TL; weakly pigmented (i.e., +) upper lip; unpigmented tongue precursor bulb; unpigmented areas lateral to the tongue precursor elastic ridge (Ref. 84195). |
