TypesHolotype: MNHN Cu 4550 (field tag number 191295), on 28 June 1990 by S. Blair Hedges, Richard Thomas, and Daniel McCallister. 
CommentDiagnosis: An apparently small species of Typhlops of the T. biminiensis species group distinguished from other members of the group by a lack of pigment (except for the eyes). From T. arator it can be distinguished by a relatively smaller and differently shaped rostral (Figs. 8, 10A in THOMAS & HEDGES 2007) and fewer dorsal scales (465–513 versus 578–579). The rostral of T. anousius is narrower dorsally (RW1) and at the labial border (RW3) than that of its closest relative, T. perimychus (Fig. 10E); RW1/RL1 = 0.74–0.77 versus 0.79–1.05 in T. perimychus. Typhlops anousius is the most extreme all the species in the width of the upper arm of the anterior nasal: ANTNAS/RW1 = 0.40–0.64 versus 0.34–0.39 in T. perimychus. In its narrow rostral T. anousius is somewhat similar to T. epactius, although its rostral is narrower (RW1/RL1, 0.74–0.77 versus 0.78–0.85) and straighter sided. Additionally, T. anousius differs from T. epactius in its lack of pigment with the latter having normally pigmented scale rows 9–11 (neck-midbody), its shorter tail (TL/TA 55–56 versus 40–48) and in being somewhat heavier bodied (TL/MBD 45–55 versus 55–58), and in having 24 scale rows (reducing at 2% TL) rather than 22 (no reduction). 
Etymology From the Greek, anousios, meaning without substance, ghostly, in reference to its lack of pigment.
