墾丁高口蝸(Hypselostoma kentingensis sp. nov.),南台灣一新種陸貝

摘要


在2010時作者的研究團隊在墾丁國家公園進行生物多樣性研究時,發現一細微陸貝,鑑定後發現因為角板與腔板融合成一角腔板,確定是高口蝸(Hypselostoma)的一新種,描述於本文。本新種與同屬其他種類比較,有以下鑑別特徵:1.在下顎板與下軸板之間有1-2枚結節狀突起,2.角腔板的角板部份比較低而不成裙擺狀外翻,3.終螺層末端游離部份稍長,4.體型較小,5.有下軸板。

A micro land snail was found in Kenting National Park during a biodiversity survey in 2010. It is identified as a new species, Hypselostoma kentingensis sp. nov., and is described in this article. This new species is distinguishable from congeneric species by having 1. one basal lamella and 1-2 basal nodules between the lower palatal lamella and subcolumellar lamella, 2. weak and not flared angular portion of anguloparietal lamella, 3. slightly longer detached whorl, 4. smaller shell dimensions, and 5. a subcolumellar lamella.
