- Ameive of the Guadeloupe (Ameiva cineracea)

This endemic terrestrial lizard strict of the Guadeloupe is known only by 3 individuals collected in 1914 with Large-Ilet (islet of less than one hectare located at 600 meters of Small-Borough).



The Indian Mongoose is probably the principal cause of its disappearance of the Guadeloupe. The cyclone of 1928 would have been fatal with the population of Large-Ilet.

This species, known only from Guadeloupe, has not been recorded since 1914. Its final extinction, presumed to be the result of a hurricane in 1928, follows a long period of decline inferred from fossil evidence and the historical literature. This decline, occurring first on large islands on which invasive mammals are now widespread, with populations surviving longer on satellite islands, is consistent with patterns of extinction following the introduction of mongoose and other exotic predators to Caribbean islands, although literature evidence suggests that the species may have had a restricted distribution on or have been lost from the large island of Guadeloupe some time prior to the first known introduction of mongoose.

This species was last known to survive on Grand Ilet off Petit-Bourg on the eastern coast of Basse-Terre, Guadeloupe, from where it was collected in 1914 (Breuil 2002). Fossil records extend its historical distribution to Guadeloupe, Marie-Galante, and their satellites (Henderson and Powell 2009).

Three individuals were collected in 1914. To date these represent the only known specimens although the species is recognizable from historical literature dating as far back as the 17th Century (Breuil 2002). This remnant population is presumed to have been destroyed by a hurricane in 1928 (Honegger 1981). Seventeenth Century sources refer to the species being ubiquitous on islands off Guadeloupe, though only present on part of the main island (Du Tertre 1654, 1667).

Available online: www.hedgeslab.org/pubs/275.pdf.

From Tucker et al. (2016):
"A more extensive phylogenetic study of West Indian Ameiva found that this island radiation was more closely related to Central American Holcosus than to South American Ameiva ameiva, though this finding was not well supported (BS = 50; Hower and Hedges, 2003). Goicoechea et al. (2016) also recovered a non-monophyletic Ameiva in their molecular study of Gymnophthalmoidea and resurrected the genus Pholidoscelis for the Caribbean species."
...
"The purpose of this study is to assess the phylogenetic relationships within Teiidae using a ‘‘next-generation” sequencing (NGS) anchored phylogenomics approach. This will provide an independent test of the findings and taxonomy proposed by Harvey et al. (2012) and Goicoechea et al. (2016). Our study recovers some well-supported differences in the higher-level phylogeny of Teiidae, but we also recover much of the phylogenetic structure proposed by Harvey et al. (2012)."
...
"Harvey et al. (2012) elected to keep the remaining South American and West Indian species together in Ameiva, though this grouping was not well supported. In contrast, Goicoechea et al. (2016) resurrected Pholidoscelis for the Caribbean ameivas due to paraphyly of the groups. Our data support the monophyly of these genera erected to address a historically paraphyletic Ameiva (Figs. 1–3). The South American group (A. ameiva and A. parecis) is more closely related to a clade of South American (Medopheos + (Cnemidophorus + Kentropyx)), whereas West Indian Pholidoscelis form the sister-group to Central American (Holcosus + Aspidoscelis deppei)."

From Day, D., (1981), The Doomsday Book of Animals, Ebury Press, London.:

Martinique was also the habitat for the Martinique Giant Ameiva (Ameiva major) which became extinct about 1960, possibly because of mongoose predation. The other extinct ameiva lizard, the Grand Islet Ameiva (Ameiva cineracea) which inhabited an islet off Petit-Bourg on the east coast of Basse-Terre, Guadeloupe, became extinct about 1920 when the islet was devastated by a hurricane.

Evolution, diversity and interactions with past human populations of recently extinct Pholidoscelis lizards (Squamata: Teiidae) from the Guadeloupe Islands (French West-Indies)

This paper aims to demonstrate how subfossil bone remains from Pleistocene and Holocene deposits can
help to reconstruct the history of recently extinct taxa through the example of Pholidoscelis lizards from
the Guadeloupe Islands in the French West Indies. To achieve this, we conducted a new anatomical and
zooarchaeological study of fossil Pholidoscelis remains collected from 23 archaeological and paleontological
deposits on the Guadeloupe Islands from which this genus is nowadays absent. Our results shed light on
the past existence of large Pholidoscelis lizards on all the Guadeloupe islands but also on the diculties of
condent specic identication for these remains. Nevertheless, we suggest a possible past occurrence of
the now extinct Pholidoscelis major on nearly all of the Guadeloupe islands. In addition, we identied a new
Pholidoscelis species, Pholidoscelis turukaeraensis sp. nov., on Marie-Galante Island, where no Pholidoscelis
lizards were previously reported. This new species underwent an increase in size after the end of the
Pleistocene period, possibly due to reduced predation pressure. We also highlight the consumption of
Pholidoscelis lizards by pre-Columbian Amerindians and the huge impact of European colonization, which
led to the extinction of all these lizards in less than 300 years.
