Etymology: Echidna: Greek, echidna = viper, 1847 (Ref. 45335); awa: Name 'awa' from the Japanese word meaning 'bubble', in reference to the spots on the jaws of the new species, which are reminiscent of bubbles. A noun in apposition.
Eponymy: In Greek mythology Echidna was a female monster, and mother of many other monsters including the Hydra. Hesiod described her as “half a nymph with glancing eyes and fair cheeks, and half again a huge snake, great and awful, with speckled skin.” (Ref. 128868), visit book page.
