We report on the predation of a veined treefrog (Trachycephalus venulosus) and an ocellated treefrog (Itapotihyla langsdorffii), both species with noxious skin secretions, by black lion tamarins (Leontopithecus chrysopygus). The two predation events took place in Morro do Diabo State Park, an Atlantic Forest reserve in southeastern Brazil. The veined treefrog was removed from a tree hollow by an adult male, whereas the ocellated treefrog was caught on the ground after it jumped from the tree attempting to escape capture. The frogs were completely ingested and no food sharing occurred in either of the events. We did not observe any signs of irritation during the event or when the group was followed in the next day in either of the cases. These are the first reports of lion tamarins ingesting anurans with noxious secretions on the skin.

黑狮狨 (Leontopithecus chrysopygus, Callitrichinae) 捕食树蛙（无尾目：狨科）的有毒皮肤分泌物

我们报告了黑狮狨猴 (Leontopithecus chrysopygus) 捕食有脉纹树蛙 (Trachycephalus venulosus) 和 ocellated 树蛙 (Itapotihyla langsdorffii) 这两种具有有毒皮肤分泌物的物种。这两次捕食事件发生在巴西东南部大西洋森林保护区莫罗杜迪亚波州立公园。有脉的树蛙被一名成年雄性从树洞中取出，而有纹的树蛙则是从树上跳下试图逃脱捕获后被抓到地上。青蛙被完全摄入，在任何一个事件中都没有发生食物共享。在任何一种情况下，我们都没有在事件期间或第二天跟踪该组时观察到任何刺激迹象。这是关于狮子狨猴摄入皮肤上有有毒分泌物的无尾目的首次报道。
