Abstract: Snow scorpionflies are notable for their unusual activity during the cold winter months as adults. Although widely distributed in boreal or high-altitude areas of the Palearctic and Nearctic Regions, their presence in China has not been documented until now. This paper reports the first discovery of three species of snow scorpionflies, Boreus altaicus Nikolajev, 2015, B. beybienkoi Tarbinsky, 1962, and B. transiliensis Nikolajev, 1998 from Xinjiang Uygur Autonomous Region, northwestern China, and provides new insights into their morphology and biology. These discoveries increase the number of known Mecoptera families in China from three to four.

摘要：雪蝎蛉因其成虫不同寻常地在寒冷的冬季月份中活动而得名。虽然在古北区和新北区的北部和高海拔地域有广泛的分布，它们此前还未在中国被记录到。本文报道三种雪蝎蛉——阿尔泰雪蝎蛉Boreus altaicus Nikolajev, 2015、贝氏雪蝎蛉B. beybienkoi Tarbinsky, 1962和伊犁雪蝎蛉B. transiliensis Nikolajev, 1998在中国西北部新疆维吾尔自治区的首次发现，并补充其形态学和生物学信息。这些发现将中国已知长翅目昆虫科的数量从三个提升为四个。
