CommentHabitat: rainforest near sea level 
EtymologyThe specific epithet “echidna” refers to the half woman–half snake monster goddess Echidna (Greek: χιδνα) from Greek mythology. According to Greek legends, Echidna married the massive monster Typhon, becoming mother of all major monsters of Greek myths (e.g., Hydra, Cerberus). Her name is used herein in reference to the contrastasting anterior/posterior coloration pattern of the new species, alluding to Echidna’s hybrid nature.
