挑战华莱士和林奈瓶颈：中国延斑蛛的研究

Challenging Wallacean and Linnean shortfalls: Ectatosticta spiders (Araneae, Hypochilidae) from China

摘要: 该文研究了青藏高原上的延斑蛛属蜘蛛。基于分子和形态学证据证实有16种延斑蛛，包括7新种：文殊延斑蛛，白马延斑蛛，何力延斑蛛，沙僧延斑，普贤延斑蛛，白象延斑蛛。从世界上只有一种延斑蛛到现在的16种延斑蛛，在10年内克服了林奈瓶颈。同时，延斑蛛过去只在陕西分布，该研究证实延斑蛛在青藏高原的东坡和南坡都有广泛的分布，突破了华莱士瓶颈。

Abstract: Ectatosticta spiders from the Qinghai-Tibet Plateau were studied. Multilocus molecular and morphological data identified 16 putative species, including seven new species: Ectatosticta wenshu Lin & S. Li sp. nov. , Ectatosticta baima Lin & S. Li sp. nov. , Ectatosticta helii Lin & S. Li sp. nov. , Ectatosticta shaseng Lin & S. Li sp. nov. , Ectatosticta puxian Lin & S. Li sp. nov. , Ectatosticta qingshi Lin & S. Li sp. nov. , and Ectatosticta baixiang Lin & S. Li sp. nov. This increase in the number of Ectatosticta species from a single species in 2008 to 16 in the current study highlights the Linnean shortfall in China. The previously known distribution of Ectatosticta spiders was from one locality in Shaanxi and is now expanded to the east and south of the Qinghai-Tibet Plateau.
