Venom effects and medical significance are different from toxicity rankings. Do not handle a snake on the basis of this summary.
The account records a marine habitat. Island names on the map identify reported coastal areas; they are not land occupancy or a boundary of the species’ marine range. Its atlas account links 1 named island or island-group record to the source literature.

A closer look
Natural history & identification
Taxonomic context
The account warns that Philippine specimens formerly identified as this species were reassigned to H. melanocephalus. A national checklist listing alone does not resolve the identity of those specimens.
Literature documented · Comment: Philippine specimen identifications
Species-level database summary; literature review, not expert validation.
The cited account does not establish population-wide variation or the conditions at every Philippine locality.
Reproduction
The species account records live-bearing reproduction, using the term ovoviviparous. A verified Philippine litter-size range and reproductive calendar are not established here.
Reproductive mode reported for this named species.
Mode alone does not establish litter or clutch size, seasonal timing, or captive husbandry requirements.
Ecology & habitat
The account records a marine habitat. Island names on the map identify reported coastal areas; they are not land occupancy or a boundary of the species’ marine range.
Literature documented · Existing checklist occurrence statement and distribution review
The original evidence level is retained.
A country listing cannot establish an island or a precise locality.

Distribution record & sources
Indian Ocean (Philippines: Visayan area, Panay; New Guinea), Gulf of Thailand, Vietnam, Indonesia and New Guinea, Australia
Type locality: New Guinea (in error, fide DAVID & INEICH 1999)
The atlas records Hydrophis belcheri from these named Philippine areas: Panay. These are literature areas rather than a continuous range boundary.
Venomous · Effects not yet summarised in this atlas
Observe from a distance. Do not handle, corner or capture a snake to identify it. An incomplete venom account is not evidence that a species is safe to handle.
After a suspected snakebite, keep the person still and arrange urgent medical care. Avoid tight tourniquets, cutting, suction and unproven remedies. Do not wait to identify the snake before seeking help.

Synonymy partly after COGGER 1983. Hydrophis pachycercos FISCHER 1855 has been removed from the synonymy of H. belcheri by RASMUSSEN et al. (200).
Distribution: not on the Solomon Islands (Bougainville Island) by McCoy 2015 although the species was listed by SMITH 193 for the Solomons. Specimens that were earlier on referred to as C. belcheri from the Philippines (AMNH 3091, BMNH 1926.5.28.11) appear to belong to the species Leioselasma melanocephala (Gray, 1849), which is widely distributed along the coasts of southern Japan, China, and Taiwan and in the Gulf of Tonkin [KHARIN 2005].
The name Aturia is preoccupied and thus all species of Aturia have been referred to Chitulia (WILLIAMS & WALLACH 1989).
Habitat: marine.
