The real identity of Leptodira nycthemera Werner, 1901 from Ecuador... 119 The real identity of Leptodira nycthemera Werner, 1901 from Ecuador: a junior synonym of Oxyrhopus petolarius

Leptodira nycthemera Werner, 1901, was described from a specimen collected in Ecuador. No information on the holotype was published after its description. In the most recent review of Leptodeira, L. nycthemera was considered to be a synonym of L. a. annulata, although the author emphasized that the holotype was lost and did not include the pholidotic data from the original description in his account of L. a. annulata. Since this review, a number of authors have accepted this synonymy. Recently, analyzing specimens of Leptodeira in the Museum für Naturkunde, Berlin, Germany, we discovered the holotype of Leptodira nycthemera. This holotype is re-described here, and its correct identity is determined. Based on the analysis of meristic characters and the color of the holotype, we recognize Leptodira nycthemera as a junior syno-nym of Oxyrhopus petolarius
