Abstract

A new genus and new species of Trechina (Coleoptera: Carabidae: Trechinae: Trechini), Ryukyuaphaenops pulcherrimus gen. & sp. nov. is described from the Ryukyu Archipelago, Japan. This is the first troglomorphic Carabidae in the Ryukyus and probably the most cave-adapted beetle in Japan. Interestingly, our observations suggest that this new trechine beetle is not similar to any genera of Trechina distributed in Kyushu and Taiwan, which are geographically close to the Ryukyu Archipelago, but is more similar to several aphaenopsian genera distributed in the inland of China. The genetic diversity of the new species is discussed based on mitochondrial DNA (COI-5’, COI-3’, 16S).

从日本西南部琉球群岛发现一种蛙形三尖杉甲虫（鞘翅目：杉科：Trechinae）

描述了来自日本琉球群岛的一种新属和新种--Ryukyuaphaenops pulcherrimus gen.这是琉球群岛的第一种蛙形甲虫，也可能是日本最适应洞穴的甲虫。有趣的是，我们的观察结果表明，这种新的三尖杉甲虫与分布在与琉球群岛地理位置相近的九州和台湾的任何三尖杉属都不相似，而与分布在中国内陆的几个甲虫属更为相似。本文基于线粒体 DNA（COI-5'、COI-3'、16S）讨论了该新种的遗传多样性。
