摘要

牙齿形态的研究是哺乳动物分类学和进化理解的基础。然而，牙齿异常可能导致错误识别和物种失效。我们报告了在河岸肌炎患者中观察到的两种不同的牙齿异常:(1)巴拿马成年男性牙弓两侧缺失第二上前磨牙(P3)的下颌畸形;(2)巴西成年男性牙弓一侧存在三个上门牙的多齿畸形。我们讨论了这些异常的遗传和生态基础，以及这些病例报告对理解蝙蝠进化发育生物学的重要性。

Dental abnormalities in Myotis riparius (Chiroptera, Vespertilionidae), with comments on its evolutionary implications

The study of tooth morphology is fundamental for the taxonomic and evolutionary comprehension of mammals. However, dental abnormalities can lead to misidentifications and species invalidations. We present two distinctive dental anomalies observed in Myotis riparius: (i) hypodontia, characterized by the absence of the second upper premolar (P3) on both sides of the dental arch in an adult male from Panama, and (ii) polyodontia, characterized by the presence of three upper incisors on one side of the dental arch in an adult male from Brazil. We discuss the genetic and ecological bases of these anomalies and the importance of these case reports for understanding the evolutionary developmental biology of bats.

期刊介绍： Mammalia is an international, multidisciplinary, bimonthly journal devoted to the inventory, analysis and interpretation of mammalian diversity. It publishes original results on all aspects of the systematics and biology of mammals with a strong focus on ecology, including biodiversity analyses, distribution habitats, diet, predator-prey relationships, competition, community analyses and conservation of mammals. The journal also accepts submissions on sub-fossil or recently extinct mammals.
