Gongylosoma pallidonuchalis

Gongylosoma pallidonuchalis (Gongylosoma pallidonuchalis) is a snake recorded for Vietnam in the project inventory. Its supporting occurrence note is “Expert range list”. The accepted scientific name is retained because regional snake taxonomy and species boundaries can change, while similar-looking species may require scale counts, anatomy or genetic evidence for reliable separation. This profile therefore distinguishes the recorded identity and occurrence from broader biological context instead of inventing unsupported locality, size, diet or breeding details (project species data; Reptile Database taxonomy).

Gongylosoma snakes are small, secretive terrestrial colubrids that occupy leaf litter, loose soil and other forest-floor cover. They forage for small prey among ground debris and may be difficult to detect because of their concealed habits and subdued coloration. Species identification depends on scalation, pattern and locality. These are genus-level biological notes rather than confirmed Vietnamese observations of this species, so exact activity, diet, body size, habitat and reproductive values are not inferred (general Gongylosoma account; Reptile Database).
