Threadsnakes are known for their conserved external morphology and historically controversial systematics, challenging taxonomic, biogeographic evolutionary researches in these fields. Recent morphological studies—mostly based on µCT data of the skull lower jaw—have resolved systematic issues within group, instance leading to description new taxa or re-positioning little-known scolecophidian tr...
