Hemitriton asper Dugès, 1852

According to the original tag on the jar, three syntypes (HE 1219–1221; Fig. 5A) of H. asper are in the MADUG. Unfortunately, Dugès’ original description does not list the number of specimens he used to describe the species, and as was the custom of the time, no holotype was designated either. Measurements of only one specimen are reported in the description; we assume these are metric, but the unit of measurement is not given. Thireau (1986) reported two additional syntypes in the Museum National d’Histoire Naturelle, Paris (MNHP 1082 (two specimens). The type locality given is the same as that in the original description. Our conclusion is that Dugès took some of the syntypes with him to Mexico; these comprise a total of five specimens.

Current valid name: Calotriton asper (Dugès, 1852) .

Abstract

The type specimens of amphibians and reptiles of the Museo de Historia Natural Alfredo Dugès, at the University of Guanajuato (MADUG) were reviewed following Smith & Necker’s (1943) summary. Owing to this collection’s eventful history and its historical importance as the oldest herpetological collection in Mexico, a review of its conservation status was needed. After many years, the collection has received proper recognition at the University of Guanajuato with a portion of the herpetological types considered “Precious Assets” of the university. We found 34 type specimens pertaining to 18 taxa; six are additional specimens to those previously reported; six herpetological types are missing, including the body of the type of Adelophis copei. All specimens are in good to reasonable condition except for the type of Rhinocheilus antonii, which has dried out completely. All specimens are illustrated to show their condition.
