The Harderian gland transcriptomes of Caraiba andreae, Cubophis cantherigerus and Tretanorhinus variabilis, three colubroid snakes from Cuba

Tropidophis feicki Schwartz, 1957 is restricted to densely forested limestone mesic areas in western Cuba (Schwartz & Henderson 1991; Henderson & Powell 2009). This species has been reported from about 20 localities distributed from near Guane, in Pinar del Río Province, to Ciénaga de Zapata, in Matanzas Province Rivalta et al., 2013; GBIF 2020; Fig. 1). On 30 June 2009 and on 22 December 2011 we found an adult male and an adult female Tropidophis feicki (ca. 400 mm SVL; Fig. 2), respectively, at the entrance of the “Cueva de la Virgen” hot cave (22.8201, -80.1384; 30 m a.s.l.; WGS 84; point 14 in Fig. 1). The cave is located within “Mogotes de Jumagua” Ecological Reserve, Sagua La Grande Municipality, Villa Clara Province. This locality represents the first record of this species for central Cuba, particularly for Villa Clara Province. This new record is about 123 km northeast (airline distance) of the nearest previous record at Playa Máquina, Ciénaga de Zapata, Matanzas Province (Rodríguez & Rivalta 2007).

Tropidophis maculatus (Bibron, 1840) is a mesophilic snake inhabiting forest patches and open secondary scrub savannas in western and central Cuba (Schwartz & Henderson 1991; Rodríguez et al. 2013). The only dietary records for this species are the lizards Anolis angusticeps and A. alutaceus, for individuals from Havana city (Collette 1961). Herein we provide new data on the diet of wild T. maculatus. On 17 April 2010, we found a juvenile female Tropidophis maculatus (140 mm SVL) at Soroa (22.7960, -83.0060; 200 m a.s.l.), Candelaria Municipality, Artemisa Province. We found the snake at 1317 hours under a rock with a big stomach bulge (Fig. 1). It later regurgitated a partially digested male Anolis homolechis that had been swallowed head first (ca. 40 mm SVL; Fig. 2). The predominant vegetation in the area is semi-deciduous forest.
