WWW.IRCF.ORG/REPTILESANDAMPHIBIANSJOURNAL T he Blindsnake family Typhlopidae (Squamata: Scolecophidia) comprises well over 40 currently recog- nized native West Indian species in as many as four genera (Hedges et al. 2014; but see also Pyron and Wallach 2014 and Nagy et al. 2015), plus the introduced invasive and parthe- nogenetic Braminy Blindsnake (Indotyphlops braminus; e.g., Wallach 2009; Hedges et al. 2014; Pyron and Wallach 2014; Domínguez 2015). In Cuba, 12 native species of Blindsnakes are currently recognized, four in the genus Typhlops and eight in the genus Cubatyphlops, in addition to I. braminus (Domínguez et al. 2013; Díaz and Cádiz 2014; Hedges et al. 2014; Pyron and Wallach 2014; Domínguez 2015). However, both in Cuba and throughout the region, addi- tional species remain to be described (Hedges et al. 2014). Probably attributable primarily to their secretive habits, the natural history of Blindsnakes is poorly known (e.g., Vitt and Caldwell 2009). In the West Indies, predators have been reported for only five species (see review in Henderson and Powell 2009; Table 1), representing only about 11% of all West Indian Blindsnakes. Moreover, these reports are lim- ited to eight predators, most of them snakes in the family Dipsadidae (Henderson and Powell 2009; Table 1). The only known instance of a lizard preying on a Blindsnake was a male Puerto Rican Crested Anole (Anolis cristatellus) eating a Puerto Rican Coastal Blindsnake (Antillotyphlops hypomethes; referred therein to the genus Typhlops; Colón 2009). Herein we report the second instance of a West Indian anole preying on a Blindsnake, in this case from eastern Cuba. At 0838 h on 9 June 2015, we observed an adult male Spanish Flag Anole (Anolis allogus Barbour and Ramsden 1919; 59 mm SVL, 3.8 g) eating a Blindsnake (Typhlops sp.; 155 mm SVL) midway up the ascending path to El Yunque (20°20’41.9”N, -74°34’01.5”W, WGS 84; 394 m asl), Baracoa, Guantánamo Province, Cuba. The lizard was resting on a bush trunk (8.5 mm diameter, 110 cm above the ground) in an almost vertical position with 57 mm (37% of SVL) of Fig. 1. Male Spanish Flag Anole (Anolis allogus) consuming a Blindsnake (Typhlops sp.) along the ascending path to El Yunque, Baracoa, Guantánamo Province.
