Etymology | The specific epithet “carsticola” is a noun in the nominative case singular used in apposition, derived from German “ Karst” (originally from Latin “ carsus”) used for “limestone landscapes” and “ cola”, a Latin word meaning “resident”, “inhabiting” or “dwelling in”. The name is given in reference to the limestone mountain habitat of the new species. The generic name “ Laodracon” is a Latinized noun in masculine nominative singular form, which gives reference to its area of occurrence in central Laos. The word “dracon” is derived from Greek “δράκων” (drakon) meaning “dragon” or a “basilisk” and refers to mythological serpents; it is widely used as a part of genus-level names within the subfamily Draconinae. |
