Type locality: 4.9 km S La Tinta, Guantánamo Province, Cuba, 5 meters elevation.  
Reproductionoviparous 
TypesHolotype: MNHN Cu 4552 (field tag number 191296), a male, collected on 29 June 1990 by Richard Thomas, S. Blair Hedges, Emilio Alfaro, and Daniel McCallister. 
CommentDiagnosis: A moderately large and slender species of the T. biminiensis group differing from all members of the species group in the Bahamas and Cuba in having a short rostral (Fig. 8), reflected in the high rostral indent (RI) value (Fig. 10F), and a large preocular apical diameter (Fig. 10C). The short rostral is also reflected in the width of the upper arm of the anterior nasal, which is relatively larger in T. contorhinus (ANT-NAS/RW1 = 0.49) than other species in the group except T. notorachius and T. anousius. It further differs from T. biminiensis in having a rostral with an acuminate posterior edge, not broadly rounded, and a more slender body (TL/MBD 63 versus 39–51). It differs from T. biminiensis, T. arator, and T. perimychus in having a narrower rostral (Fig 10A) that is relatively broad on the apex of the snout (Fig. 8). From T. perimychus, it also differs in being larger (316 mm versus 280 mm TL), having more middorsal scales (502 versus 453– 496), and a more slender body (TL/MBD 63 versus 41–59). In body shape, it is more slender (TL/MBD 63) than T. notorachius, T. anousius, and T. arator (Table 2). From T. anousius, it also differs in having scale row reduction at 31% TL rather than 2% TL. From T. arator, it further differs in having 24–22 scale rows rather than 26–24 rows and in having fewer middorsal scales (502 versus 578–579). 
EtymologyFrom the Greek, kontos, short, and rhinos, nose, an adjective meaning short-nosed.
