Bottom Line: Generally, we found that south and south-west of Japan, Philippines Archipelago, parts of Indonesia, and Vanuatu have the highest diversity of sea krait species.The occurrence records were georeferenced and compiled as a database for each sea krait species.This database can be freely used for future studies.

ABSTRACT
The genus Laticauda (Reptilia: Elapidae), commonly known as sea kraits, comprises eight species of marine amphibious snakes distributed along the shores of the Western Pacific Ocean and the Eastern Indian Ocean. We review the information available on the geographic range of sea kraits and analyze their distribution patterns. Generally, we found that south and south-west of Japan, Philippines Archipelago, parts of Indonesia, and Vanuatu have the highest diversity of sea krait species. Further, we compiled the information available on sea kraits' occurrences from a variety of sources, including museum records, field surveys, and the scientific literature. The final database comprises 694 occurrence records, with Laticauda colubrina having the highest number of records and Laticauda schistorhyncha the lowest. The occurrence records were georeferenced and compiled as a database for each sea krait species. This database can be freely used for future studies.

Figure 6: Distribution of Laticaudasaintgironsi, regional view and zoomed in (A).

Mentions: Laticaudacolubrina has the largest range of any sea krait species (Table 1; Figure 3; Suppl. material 1), spanning from Tonga, in the south-east, through Fiji, Vanuatu, the Solomon Islands, New Guinea, Palau, most of the Indonesian coast, the Philipines, Taiwan, and reaching its northernmost limits in southern Japan and its westernmost limits in the Bay of Bengal, in the Andaman Islands and on the Myanmar coast (Figure 3; Suppl. material 1). Although the species exhibits a great degree of morphological variability across its distribution range, all populations are currently regarded as a single species (Heatwole 2010; Heatwole et al. 2005; Heatwole and Cogger 2013; Lane and Shine 2011b). In contrast, all other species of the Laticaudacolubrina group have very narrow distribution ranges. Laticaudafrontalis is considered endemic to Loyalty Islands and the islands of Vanuatu (Cogger and Heatwole 2006) (Figure 4; Suppl. material 1). Except for this latter location, the available records indicate that the species is sympatric with Laticaudacolubrina throughout Vanuatu (Figures 3 and 4; Suppl. material 1). Laticaudaguineai has a very small distribution range, known from only two areas in southern Papua New Guinea (Heatwole et al. 2005) (Figure 5; Suppl. material 1). Laticaudasaintgironsi is endemic to New Caledonia, including the Loyalty Islands (Figure 6; Suppl. material 1), as reported by other authors (Cogger and Heatwole 2006; Heatwole and Cogger 2013). In the Loyalty Islands, the species occurs in sympatry with Laticaudafrontalis (Figures 4 and 6; Suppl. material 1).
