Abstract

A new species, , is described from the ancient lake Matano, Sulawesi island, Indonesia. The morphology of this species was studied by means of light and scanning electron microscopy. has a remarkable valve ultrastructure. The valve surface is ornamented with numerous longitudinal siliceous ribs and siliceous verrucae. Valve face delineated from the mantle by a thickened marginal ridge. Raised sterna border the raphe branches. Raphe is distinctly undulate with distal ends hooked strongly to the ventral side. The only similar species to is described from New Caledonia. Comparison of both taxa is given and is transferred to . The taxonomic placement of both taxa is evaluated, and the phenomenon of external siliceous ornamentation is discussed.

摘要

一种新物种,[物种名称未给出],是从印度尼西亚苏拉威西岛的马塔诺古湖描述的。通过光学显微镜和扫描电子显微镜对该物种的形态进行了研究。[物种名称未给出]具有显著的瓣膜超微结构。瓣膜表面装饰有许多纵向硅质肋和硅质疣。瓣膜面由加厚的边缘脊与套膜分隔。凸起的腹板与中缝分支相邻。中缝明显呈波浪状,远端强烈钩向腹侧。与[物种名称未给出]唯一相似的物种是从新喀里多尼亚描述的[另一物种名称未给出]。给出了两个分类单元的比较,并将[物种名称未给出]转移到[另一分类单元名称未给出]。评估了两个分类单元的分类位置,并讨论了外部硅质装饰的现象。
