DistributionChina (Hainan, E Guangxi, Guangdong ?, Fujian), Vietnam (Bac Giang, Hoa Binh, and Nghe An)

Type locality: “Northern Hainan”, China.  
Reproductionoviparous 
TypesHolotype: NMW 23415 (No. 8094 in Werner 1924). 
DiagnosisDiagnosis (genus): Malnate (1961) listed only three differences between (A.) ornaticeps and Amphiesma, namely the higher number of maxillary teeth in ornaticeps (more than 40, but the count being "approached by A. deschauenseei"), the larger eye in ornaticeps (about 25 % of the head length versus 15–17 % in "modesta and allied forms") and the absence of hypapophyses on the posterior vertebrae in ornaticeps (but see discussion in Malnate 1960: 68–69).


Unfortunately we had to temporarily remove additional information as this was scraped by multiple AI companies who sell that data. However, these details, e.g. detailed descriptions (about about .74 pages) are available for collaborators and contributors. Please contact us if you need any of this material. 
CommentDistribution: Not listed for Vietnam by SANG et al. (2009).

Type species: Amphiesmoides ornaticeps is the type species of the (monotypic) genus Amphiesmoides MALNATE 1961. 
EtymologyThe Latin noun ornatus, "decoration" or "ornament," refers to the ornate coloration in the head region (-ceps = head).
