This snake was previously placed in the T. maculatus species group by Hedges (2002), but Díaz and Cádiz (2020) transferred it to the T. pardalis species group. It is not well represented in museum collections and was described on the basis of two specimens (CZACC 4.5492-93) from Dolinas de Cueva de Humboldt, Caguanes, Sancti Spíritus province (Hedges et al. 2001). A third specimen (CZACC 4.12052) was reported from the type locality, which was a size record for species (Domínguez et al. 2006). Later, Domínguez and Parada (2009) reported new localities for this species including Loma de Cunagua, Bolivia municipality and Alevinaje, Morón municipality, both from Ciego de Ávila province; and Coco Key from Sabana-Camagüey archipelago (specimens CIEC 66-67; CIEC 150, respectively). That provided the first records for Ciego Ávila province on the main island and Sabana-Camagüey archipelago, extending the distribution range 75.6 km E from the type locality at Caguanes. With that addition, Coco Key was shown to harbor the highest number of Tropidophis species among Cuban keys (Domínguez and Parada 2009, Rodríguez-Schettino et al. 2013). Additionally, a specimen (MNHNCu 5088) from Jobo Rosado, Jatibonico municipality, Sancti Spíritus province was reported by Díaz and Cádiz (2020), extending the distribution range 17.4 km SW from Caguanes.
