Systematics and diversification of Anindobothrium Marques, Brooks & Lasso, 2001 (Eucestoda: Rhinebothriidea)

Tapeworms of the genus Anindobothrium Marques, Brooks & Lasso, 2001 are found in both marine and Neotropical freshwater stingrays of the family Potamotrygonidae. The patterns of host association within the genus support the most recent hypothesis about the history of diversification of potamotrygonids, which suggests that the ancestor of freshwater lineages of the Potamotrygonidae colonized South American river systems through marine incursion events. Despite the relevance of the genus Anindobothrium to understand the history of colonization and diversification of potamotrygonids, no additional efforts were done to better investigate the phylogenetic relationship of this taxon with other lineages of cestodes since its erection. This study is a result of recent collecting efforts to sample members of the genus in marine and freshwater potamotrygonids that enabled the most extensive documentation of the fauna of Anindobothrium parasitizing species of Styracura de Carvalho, Loboda &amp...Anindobothrium Marques, Brooks & Lasso, 2001属的绦虫，可寄生于海产魟类以及江魟科(Potamotrygonidae)的新热带淡水魟。该属内的宿主关联模式，支持了当前关于江魟科分化历史的最新假说——该假说认为，江魟科淡水支系的祖先通过海侵事件定殖至南美水系。尽管Anindobothrium属对于理解江魟科的定殖与分化历史具有重要意义，但自该类群被建立以来，尚未有后续研究深入探究其与其他绦虫纲支系的系统发育关系。本研究依托近期针对海产及淡水江魟体内该属类群的采集工作，实现了对寄生于Styracura de Carvalho, Loboda &...属物种的Anindobothrium类群迄今为止最全面的类群记录。
