Description
Original diagnosis after Kirkland, Eaton & Brinkman, 2013 [20268]: Small species of Texatrygon similar to T. avonicola in nearly all characters except that oral teeth have a marked depression at center of uvula expansion and weak cusplets extend up from around margin of tooth (Fig. 9.21A–W).
