• Relatively abundant at the type locality but overall sampling remains limited (more records likely) Zenodo

🖼 Appearance & Ontogeny

• Overall background is beige to light brown with increasingly tight and conspicuous spotting as specimens grow Zenodo
• Significant variation in body proportions—e.g., head-length, cleithral width, and caudal peduncle length—observed between the holotype and paratypes (up to ~50 mm difference), suggesting ontogenetic change Zenodo
