Plethodon neomexicanus are slim, elongated and short-legged salamanders. Females average 55.5 mm and males average 54.4 mm in length. They usually have 18-19 costal grooves and 19-20 trunk vertebrae (Williams 1973).

Adults are brown with fine brassy-colored stippling dorsally (Stebbins 2003). Ventrally, the pigment is reduced to the extent that they almost appear transparent (Williams 1973).

Young Plethodon neomexicanus have faint gray or brassy dorsal stripes. Molecular data indicate that these salamanders are mostly closely related to Plethodon larselli , the Larch Mountain salamanders (Stebbins 2003).
