Abstract
We describe a new species of the plethodontid salamander genus Cryptotriton from Honduras after comparing morphological, molecular, and osteological data from the holotype to that of the other nominal forms of the genus. The new species differs from all of the known species of Cryptotriton in at least one character from all three datasets. We also suggest placing C. wakei in the synonymy of C. nasalis after examining the morphological and osteological characters of the single known specimen of C. wakei.

Etymology. The specific name necopinus is a Latin adjective for unexpected. That name has two meanings in connection with the finding of this new species. Firstly, finding a member of Cryptotriton about 125 km SE of its previous eastern most known locality was certainly unexpected. Secondly, a group of seven collectors had spent six days and five nights in the area searching for amphibians and reptiles during March 2007 (Townsend et al. 2007) and at least two of those collectors had spent about a week in the area during 2006 (Townsend & Wilson 2009, Townsend et al. 2009). Thus, it was also unexpected to find an undescribed salamander species at the locality in such a short time period (two days and nights) after so many productive man-hours were previously spent there.
