CommentDiagnosis. Typhlops mcdowelli is most closely related to T. depressiceps but distinguished therefrom by its total middorsal count (431 - 464 vs. 631 - 713), length/width rat io (44 - 53 vs. 61- 81), dorsal rostral shape (oval vs. parallel) and posterior rostral border (angled vs. linear), angle of preoral snout in lateral aspect (inclined at 30° vs. horizontal), vertical position of tip of rostral keel in lateral view (above supra labials vs. below supralabials), gular region (visible in lateral profile vs. invisible), and apical spine (short, needlelike and horizontally oriented vs. long, transversely flatt ened and vertically oriented) (Table 2 in WALLACH 1996). 
EtymologyNamed after Samuel B. Mcdowell, American herpetologist (1928-2014).
