Abstract

Until now, Molossus melini was known only from its type locality, in the south of Santa Fe province, Argentina. Specimens of this species were collected in 2021 from a roost in a Fraxinus tree of the urban woodland of Paraná city, Entre Ríos province, Argentina. Bat identification was made by comparing external and cranial characters and measurements with those reported in the bibliography and corroborated by a phylogenetic analysis based on the cytochrome b gene. Also, multivariate morphometric analyses showed that cranial measurements, but not external ones, are informative enough to discriminate M. melini from the other Molossus species in Argentina (M. currentium, M. fluminensis, and M. molossus). This new record extends the distribution of M. melini from the south of Santa Fe province by 230 km to the northeast and represents the first record of the species in the Espinal ecoregion.

形态和分子分析证实，阿根廷Espinal生态区存在新描述的蝙蝠物种Molossus melini。

到目前为止，人们只知道Molossus melini位于阿根廷圣达菲省南部的典型地区。该物种的标本于2021年从阿根廷恩特雷里奥斯省巴拉那市城市林地的一棵Fraxinus树上的栖息地采集。蝙蝠的鉴定是通过将外部和头部特征和测量结果与参考文献中报道的进行比较来进行的，并通过基于细胞色素b基因的系统发育分析来证实。此外，多变量形态计量学分析表明，颅骨测量（而非外部测量）的信息足以将M.melini与阿根廷的其他Molossus物种（M.currentium、M.fluminensis和M.Molossus）区分开来。这一新记录将M.melini的分布从圣达菲省南部向东北延伸了230公里，并代表了该物种在西班牙生态区的第一个记录。补充信息：在线版本包含补充材料，可访问10.1007/s13364-023-00679-1。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
