Hylodes alfredi Boulenger, 1898

Two specimens (HE 1038, 1039, Fig. 11A–B) in the MADUG are labeled as types. We cannot assign these specimens to the category of types since there is no indication in the original description by Boulenger that he used more than the two specimens sent to the British Museum by Dugès and these are catalogued as BMNH 1947.2.15.54 (formerly 98.2.19.1) and 1947.2.14.55 (formerly 98.4.7.1) (see Frost 2015 for more details). The specimens at the MADUG and those used by Boulenger all are from Atoyac, Vera Cruz (Veracruz). It is possible that Dugès had a large series of specimens of which a subset were sent to the Natural History Museum, London, and after Boulenger’s description Dugès labeled as types the specimens he had retained. Although they may be topotypes they have no status as primary types.

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.
