Bothriechis nigroviridis
species of reptile

Bothriechis nigroviridis is a pit viper species found in the mountains of Costa Rica and Panama. No subspecies are currently recognized. The specific name is derived from the Latin niger (black) and viridis (green) in reference to its distinctive color pattern.
Common names
Black-speckled palm-pit viper, speckled palm viper, black-spotted palm viper, yellow-spotted palm viper.
Description
Adults may exceed 80 centimetres (31 in), although most are less than 60 centimetres (24 in) in length. They are relatively slender and have a prehensile tail. Two exceptionally large females were reported by Hammack and Antonio (1991) that measured 89.2 centimetres (35.1 in) and 93.7 centimetres (36.9 in).
The color pattern usually consists of an emerald green (rarely yellowish green) ground color with strong black mottling. There may also be pale green dorsal blotches that have black edges. The belly is yellowish green and lightly mottled with black.
Begin with the source’s own compact description: “Bothriechis nigroviridis” is species of reptile. The dossier treats that line as a proposition to test through Bothriechis, nigroviridis and species, not as a finished interpretation.
Why this record matters
The phrase “species of reptile” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Sep 29, 2025. The linked authority identifier is Q839883. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1991.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
