Figure 4 AIguana insularis sanctaluciae hatchlings (northeast Saint Lucia) B hatchling I. insularis insularis (IGU143, Union Island, Grenadines). The I. insularis hatchlings in both A and B show strong dark green to light green banding on the body and the tail, with a white mark at the scapular level C hatchlings alien I. rhinolopha in Florida. These iguanas have a nearly uniform green body with only some brown narrow banding on the body.

Figure 3 Photographs of three adult male Iguana insularis insularis on the Tobago Cays (Grenadine Islands). A IGU105 (Baradal). This male has the typical coloration of I. insularis insularis with faint black banding, eye with visible white area, nasal horns, small subtympanic plate and very few and small tubercles on the neck, but also presents atypical sublabial scales and conical scales on the nape B IGU112 (Petit Rameau) is a typical older male I. insularis insularis, with no black bands on the body (not shown in this photograph) C IGU110 (Petit Bateau) has a body with small and narrow ventral black bands and numerous black scales on the body. 1. relatively small subtympanic plate 2. mosaic of small scales 3. very low to low number of small neck tubercles 4. lateral and median horns 5. white visible in the eye. 6. brown eye 7. light cream coloration in old adults; green in juveniles and younger adults 8. light dewlap with some black scales (C) 9. small number of small gular spikes (not always visible on the photographs) 10. light body with different degrees of persistence of black stripes 11. light and high dorsal spikes with a pink or orange hue.

Figure 2 Distribution of iguanas in the Grenadine Islands (modified from Henderson and Powell 2018; Breuil et al. 2019). Note there are alien iguanas on some islands and not all of the island clusters shown here have purebred populations of I. insularis insularis. The grey line south of St. Vincent marks the break between the Saint Vincent Bank to the north and the Grenada Bank to the south. The black line between Petit St. Vincent and Petit(e) Martinique shows the political boundary between St. Vincent and the Grenadines to the north and Grenada to the south. The Grenadine Islands form an archipelago from the south of St. Vincent to the north of Grenada. Almost all the Grenadine Islands in St. Vincent and the Grenadines were surveyed during this work and, with the exception of Savan Island, had iguanas at the time of our visits. Petit Mustique was inaccessible during our survey. The islets of Sugar Loaf, Green Island,c and Sandy Island (all in Grenada) are reported to no longer have iguanas (Henderson and Powell 2018) but iguanas fitting the morphology of I. insularis insularis have been observed on Carriacou and Mabouya Islands (see text).

Figure 1 A distribution of the five Iguana species recognized by Breuil et al. (2020). The Lesser Antilles contain three endemic species (I. delicatissima, I. insularis, I. melanoderma) and the invasive aliens I. iguana and I. rhinolopha, which hybridize with the endemic insular taxa. The grey line between Central and South America indicates the approximate limit between the two recognized continental species, but the taxonomy and distribution of iguanas in this area warrants further investigation B the three geological banks referred to in this paper are separated by two horizontal dash black lines. The black line indicates the political boundary between the country of St. Vincent and the Grenadines to the north and Grenada to the south. The iguanas are named according to the results of this study and Breuil et al. (2020).

Figure 1 Map of Montserrat showing approximate collection localities of Chlamydotheca unispinosa. Empty valves were collected from a dry pool along Blackwood Allen Trail (A) and in a muddy puddle along Jack Boy Hill Trail (B).

Figure 3 Neighbor-Joining tree of COI nucleotide sequences (codon positions 1, 2, and 3) from the Montserrat specimen of Chlamydotheca unispinosa, four of the most similar sequences and one outgroup. All positions containing gaps and missing data were eliminated. There was a total of 620 positions in the final dataset. Bootstrap values (1000 replicates) are shown at each node. Branch lengths represent evolutionary distances (p-distance) and are in the units of the number of base differences per site. All analyses were completed in MEGA 7 (Kumar et al. 2016).
