DiagnosisUnfortunately we had to temporarily remove additional information as this was scraped by multiple AI companies who sell that data. These details, e.g. detailed descriptions are available for collaborators and contributors. We will relaease that material sometime next year. Please contact us if you need any of this data earlier than that. 
CommentSynonymy: mostly after LEVITON 1965. Boulenger (1893: 368) placed Lycodon muelleri Dumeril et al. in the synonymy of Stegonotus dumerili. Boulenger probably proposed this latter name as a substitute for L. muelleri which, in the genus Stegonotus, was preoccupled by a senior homonym. Bernstein et al. 2026 proposed to renamed Lycodon muelleri to Stegonotus philippinensis, as the former is a homonym of Stegonotus muelleri (when moved to Stegonotus).

Distribution: the original type locality, “Java” is clearly in error; 
Etymologynamed after Johannes Peter Müller (1801-1858), German biologist and anatomist.
