The diagnosis contrasts a yellow underside with a dark midventral line against the orange-to-salmon underside of H. philippinum. It also reports fewer paired dark dorsal spots, with colour and scalation considered together. Its atlas account links 1 named island or island-group record to the source literature.

Natural history & identification
Appearance & identification
The diagnosis contrasts a yellow underside with a dark midventral line against the orange-to-salmon underside of H. philippinum. It also reports fewer paired dark dorsal spots, with colour and scalation considered together.
Literature documented · Diagnosis: comparison with H. philippinum
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 egg-laying reproduction. A verified Philippine clutch-size range, incubation interval and breeding calendar are not established here.
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.
Taxonomic context
Hologerrhum dermali is retained in the atlas’s dated checklist under Cyclocoridae. The authority is BROWN, LEVITON, FERNER & SISON 2001. Earlier names and the original source notes are preserved below for comparison.

Distribution record & sources
Philippines (Panay)
Type locality: 1500 m elevation in the area known locally as “Hang-gud Tubig” (“Big Water”), on the western face of Mt. Madja-as, Barangay Alojipan, Municipality of Culasi, Antique Province, Panay Island, Philippines.
The atlas records Hologerrhum dermali from these named Philippine areas: Panay. These are literature areas rather than a continuous range boundary.
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.
