Lycodon subannulatus(DUMÉRIL, BIBRON & DUMÉRIL 1854)
The species account records climbing or partly arboreal habits. It does not quantify the time spent in trees or establish a single habitat preference across its range. Its atlas account links 1 named island or island-group record to the source literature.

A closer look
The 2026 revision uses Dryocalamus subannulatus. This page retains the earlier checklist name and address for continuity.
Literature documented · Section 4.3, pp. 13–14
Nomenclatural update; the original checklist and records remain separate.
Biological records are not reassigned between species by a change of genus alone.
The species account records egg-laying reproduction. A verified Philippine clutch-size range, incubation interval and breeding calendar are not established here.
Literature documented · Reproduction field
Reproductive mode reported for this named species.
Mode alone does not establish litter or clutch size, seasonal timing, or captive husbandry requirements.
The species account records climbing or partly arboreal habits. It does not quantify the time spent in trees or establish a single habitat preference across its range.
Literature documented · Comment: Habitat
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.
The atlas records Lycodon subannulatus from these named Philippine areas: Palawan. These are literature areas rather than a continuous range boundary.
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.
Across the archipelago
Documented islands: gold · island groups: dashed circles
Island-level records · not continuous habitat coverage. Dashed circles locate groups, not individual observations.

Living with wildlife
Venom classification not yet added · 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.
