Abstract:
A peculiar population of Ravenna nivea (Nire, 1920) was discovered from the Yinggeling Mountain Mass of central Hainan. Its wing pattern and COI barcode data show considerable distinction from other geographic populations of R. nivea, including that of Bawangling, approximately only 40 km away and also located in Hainan. The p-distance value of the COI barcode between the Yinggeling and Bawangling populations was 1.1%, considerably higher than the value (0.6%) between Bawangling population and populations in eastern China, where the subspecific name howarthi Saigusa, 1993 applies. The population is regarded as a distinct subspecies ngiunmoiae Lo & Hsu, subsp. nov. The distinctness and high degree of COI haplotype diversity of R. nivea found in Hainan and Taiwan suggest continental islands may serve as glacial refugees for the butterfly and other organisms during previous glaciations, and the presence of the relict populations of montane butterflies like R. nivea may provide useful clues towards a better understanding of the geological history of mountain formation within islands.
摘要:
一个特殊的拉文纳妮维娅人口(Nire,1920)是从海南中部的鹦哥岭山群中发现的。它的机翼模式和COI条形码数据显示与R.nivea的其他地理种群有很大区别,包括霸王林的,大约只有40公里远,也位于海南。鹦哥岭和霸王岭种群之间的COI条形码的p距离值为1.1%,大大高于霸王人口与中国东部人口之间的数值(0.6%),子特定的名字howarthiSaigusa,1993年适用。该种群被认为是一个独特的亚种ngiunmoiaeLo和Hsu,subsp.11月。在海南和台湾发现的R.nivea的COI单倍型多样性的独特性和高度表明,大陆岛屿可能在先前的冰川时期成为蝴蝶和其他生物的冰川难民,像R.nivea这样的山地蝴蝶的残存种群的存在可能为更好地了解岛屿内山脉形成的地质历史提供有用的线索。
