    How integrative taxonomy can save a species from extinction: The supposedly extinct mouse opossum Cryptonanus ignitus (Diaz, Flores and Barquez, 2000) is a synonym of the living C. chacoensis (Tate, 1931)

    We reviewed the taxonomic status of the “extinct” mouse opossum Cryptonanus ignitus (Diaz, Flores and Barquez, 2000). This species is only known from the type, an adult male collected in the province of Jujuy, northwestern Argentina, in 1962. Based on both qualitative and quantitative external and cranial traits and the analysis of DNA sequences extracted from the 57-year-old type skin, we confirm the suggestion of previous researchers that C. ignitus is an elderly example of the living species C. chacoensis (Tate, 1931). Most of the supposedly diagnostic morphological traits of C. ignitus (e.g., zygomatic arches unusually wide and robust, postorbital process of the jugal massively developed, prominent temporal scars) are age-correlated in didelphids and were observed in other adult specimens of C. chacoensis. The clay coloration of the ventral pelage of C. ignitus, which allegedly sets apart this species from other congeners, is here reported for new examples of C. chacoensis from other localities. Our results suggest the need to carefully evaluate the taxonomic status of other species supposed to have become extinct in recent times in mainland South America. © 2019 Deutsche Gesellschaft für Säugetierkunde

    Molecular and morphological identification of Phylloderma stenops Peters, 1865 (Chiroptera, Phyllostomidae) and new records for Colombia
    (Centro de Referencia em Informacao Ambiental, 2019-01-01) Martínez-Cerón J.M.; Patiño-Castillo E.; Carvalho-Madrigal S.; Díaz-Nieto J.F.; Universidad EAFIT. Departamento de Ciencias; Biodiversidad, Evolución y Conservación
    Based on revisionary work of recently collected material in Colombian museums we confirm the presence of Phylloderma stenops Peters, 1865 in 6 new localities for the country, including the first record of the species in the dry lowlands of the northern Caribbean coast, and the increase by more than 800 m of the elevational range of the species in Colombia. DNA-barcoding confirmed our morphological identification, and supported a paraphyletic composition of the cis-Andean populations. Our records exemplify the little knowledge on the ecogeographic distribution of this species and provide further evidence to consider this as a widespread but rare species. © Martínez-Cerón et al.
