The pierid Charonias theano (Boisduval), an endangered butterfly species, has been rarely observed in nature, and has not been recorded in the state of São Paulo in the last 50 years despite numerous efforts to locate extant colonies. Based on museum specimens and personal information, C. theano was known from 26 sites in southeastern and southern Brazil. Recently, an apparently viable population was recorded in a new locality, at Serra do Japi, Jundiaí, São Paulo, with several individuals observed during two weeks in April, 2011. The existence of this population at Serra do Japi is an important finding, since this site represents one of the few large forested protected areas where the species could potentially persist not only in the state of São Paulo, but within its entire historical distribution.
濒危蝴蝶物种——皮耶里德绢斑蝶（Charonias theano，由布瓦杜瓦尔命名）在自然界中很少被观察到，尽管人们为寻找现存种群付出了诸多努力，但在过去50年里，圣保罗州都没有该物种的记录。根据博物馆标本和个人信息，绢斑蝶在巴西东南部和南部的26个地点被发现过。最近，在圣保罗州容迪亚伊市的雅皮山（Serra do Japi）一个新地点记录到了一个显然有生存能力的种群，2011年4月的两周内观察到了几只个体。雅皮山存在该种群是一项重要发现，因为这个地点是少数几个大型森林保护区之一，该物种不仅有可能在圣保罗州，而且在其整个历史分布范围内继续生存。
