New distribution records and variation of the two common lowland salamanders Bolitoglossa colonnea (Dunn, 1924) and B. lignicolor (Peters, 1873) in Panama (Amphibia: Caudata: Plethodontidae)

We revise the geographic distribution of two common lowland salamanders in western Panama. We close the widest gap in the known distribution of Bolitoglossa colonnea with a first record for the province of Veraguas and extend its known vertical distribution to a third life zone. For B. lignicolor we present additional localities in the province of Chiriquí and the first record from Comarca Ngöbe-Buglé that close the gap between extreme western Panama and the Azuero Peninsula. We present morphological, molecular, and coloration data for both species.
