First record of Mirinaba cadeadensis (Gastropoda: Strophocheilidae) in an anthropogenic shell mound from the Paraná coast, Southern Brazil

ABSTRACT Mirinaba cadeadensis Lange de Morretes, 1952 is restricted to the Paraná state, and found at the municipalities of Morretes, São José dos Pinhais, Paranaguá, Matinhos, and Guaratuba, associated to the Serra do Mar mountains. In this paper, we report the first record of this species in an anthropogenic shell mound. Two shells of M. cadeadensis were located in the internal stratigraphic layers of the Boguaçu shell mound. This is also the first shell mound record for Mirinaba.【摘要】由Lange de Morretes于1952年命名的卡氏米拉巴蜗牛（Mirinaba cadeadensis）仅分布于巴西巴拉那州，目前已知的分布地涵盖莫雷特斯、圣若泽杜斯皮尼亚伊斯、帕拉纳瓜、马廷斯及瓜拉图巴等市镇，其栖息环境与马尔山脉（Serra do Mar）密切相关。本研究首次报道了该物种在人为贝丘生境中的分布记录：在博瓜苏贝丘的内部地层层位中发现了2枚卡氏米拉巴蜗牛的贝壳。此次记录同时也是米拉巴蜗牛属（Mirinaba）物种在贝丘生境中的首次发现记录。
