A new locality and reproductive record for the Hispaniolan Gracile Boa (<i>Chilabothrus gracilis</i>)

phis, C. fordii, C. gracilis, and C. striatus) are endemic to Hispaniola and some of its satellite islands (Reynolds et al. 2023).The latter species is a large-bodied generalist, reaching a reported maximum snout-vent length (SVL) of 2,000 mm, whereas the other three species are smaller, with SVLs no longer than 905 mm, and more specialized (Henderson and Powell 2009;Reynolds et al. 2023).Of these, C. gracilis (Fig. 1) is considered the most specialized in both morphology and ecology, with a characteristic long, slender, and strongly laterally compressed body (Henderson and Powell 2002;Reynolds et al. 2016).The species is polytypic, with the nominate subspecies, C. g. gracilis, inhabiting largely coastal areas of much of the island (Fig. 2) and C. g. hapalus occurring basically along the Tiburon Peninsula in southwestern Haiti.The taxonomic status of the disjunct population from the Barahona Peninsula remains unknown.The species is listed as Near Threatened (NT) on the IUCN Red List of Threatened Species (Henderson et al. 2021) and as Vulnerable (VU) on the Dominican Lista Roja Nacional (MIMARENA 2019).New locality and distribution.-Weherein report a new locality in the Distrito Nacional, Santo Domingo Province, Dominican Republic, along the southern coast of the island (Fig. 3), where an adult female was captured (Fig. 1) on 6 September 2023 at Cuesta Hermosa II, Av.Jacobo Majluta next to the Rio Isabela (18.51481, -69.95282).This is the first record along the southeastern coast of Hispaniola.Photographic vouchers of the adult female and one of her neonates (see below) have been deposited in the Florida Museum of Natural History (UF:Herp:195940-1).The identity of the species was confirmed by Robert Powell.Habitat at the new locality is adjacent to a mesic riparian forest with some level of disturbance, but the canopy cover is quite dense and a good portion of the area supports some undergrowth.Typical habitat of the species is thought to be lowland wooded forests, often associated with rivers
