| Comment | |
| Etymology | Named after the large, terrestrial, golden-colored, non-winged dragon, Glaurung in Middle-earth – a character created by J.R.R. Tolkien in The Silmarillion (1977). Glaurung the Golden is the father of all dragons and tunneled into the sides of mountains forming burrows. The reduced expandable lateral flanks, yellow ventral and dorsal colors, with the construction of burrows beneath rocky outcrops is similar to the descriptions of Glaurung mentioned above, from ‘The Silmarillion’ and ‘The Children of Húrin’ (Tolkien 1977, Tolkien and Tolkien 2007). |
