Figrue 2 in The diversity and distributions of the beetles (Insecta: Coleoptera) of the Guadeloupe Archipelago (Grande-Terre, Basse-Terre, La Désirade, Marie-Galante, Les Saintes, and Petite-Terre), Lesser Antilles
Figrue 2. Outline map of physical relationships of the individual islands of the Guadeloupe Archipelago. Note the -200 isobath lines indicating the extent of the Guadeloupe Bank. This approximately shows the maximum of the increased areas of the islands during Pleistocene glacials, when sea levels were lower than at present, and only three separate islands ("Grand Guadeloupe," and Les Saintes, and Marie-Galante) existed (Clark et al. 2009).

Figure 1. The islands of the central and eastern West Indies and adjacent continental land masses, showing in the east the main island arc of the Lesser Antilles and the location of the Guadeloupe Archipelago.
Figure 4 in The beetles of the Lesser Antilles (Insecta, Coleoptera): diversity and distributions
Figure 4. General fluctuation of relative sea levels (RSL) in the later part of the Pleistocene, derived from Waelbroeck et al. (2002) and Shackleton (2000) by Lascu (2005). This shows how varying were the sea levels (and thus island shorelines and island areas) through the last quarter of the Pleistocene. The result is that at times of lower sea levels during global glacials the islands of the Lesser Antilles had more exposed land and were closer to each other and overwater dispersal between islands was facilitated. Additionally, over this time span the higher islands of the southern islands were increasing in area and elevation through volcanic activity.
Figure 5 in The beetles of the Lesser Antilles (Insecta, Coleoptera): diversity and distributions
Figure 5. The larger and sometimes connected paleo-islands of the eastern West Indies at times of maximum low sea levels during the last glacial, about 26,000 to 20,000 yBP. Some of the present islands of the Lesser Antilles thus had considerably larger areas and were joined with other islands on their marine bank as continuous land, and the islands were closer to each other. The glacial low sea levels approximated the insular shelf margins. The isobath (depth) line is shown here at -200 m below the present sea level. The evidence for sea level depression in the last glacial is for a decrease of as much as -150 m (Clark et al. 2009). The larger island areas are the exposed submarine banks that represent the true biogeographic islands that were isolated from each other. Note that some of the islands paralleling the north coast of South America were still isolated by seawater and were thus oceanic islands, even though they lie on or near the continental shelf of South America.
