   • A living fossil: It is considered a significant species in evolutionary biology, representing the sole surviving member of its genus (Mastotermes) and family (Mastotermitidae). Its physical and biological characteristics show primitive traits that are seen as an evolutionary link between cockroaches and more modern termites.

Usage Examples

• Noun:
  • The unique digestive system of Mastotermes darwiniensis is of great interest to scientists.
  • Conservation efforts are important for Mastotermes darwiniensis due to its limited habitat range.
