摘要

描述了婆罗洲石灰岩山上的二新种:产自马来西亚沙捞越的D. heteropleura sp. nov.和产自印度尼西亚东加里曼丹的D. stenoacron sp. nov.。第一种在婆罗洲的横纹中是独一无二的，它有放射状的横纹:在所有的轮毂上都有很宽的间隔，除了最后的1.5个轮毂，在那里它们的间隔很近;第二种属于没有放射状肋骨的一小群物种，但比它们中的任何一种都大。

Two new species of Diplommatina Benson, 1849 (Gastropoda, Caenogastropoda: Diplommatinidae) from Borneo

Two new species of Diplommatina from limestone hills on Borneo are described: D. heteropleura sp. nov., from Sarawak (Malaysia) and D. stenoacron sp. nov., from East Kalimantan (Indonesia). The first is uniquely identified among the Bornean Diplommatina by the arrangement of radial ribs: widely spaced on all whorls except the last 1.5, where they are closely spaced; the second belongs to a small group of species without radial ribs but is larger than any of them.
