Abstract

Chironomids of the genus Shilovia Makarchenko (Diamesinae, Boreoheptagyiini) from the mountains of Central Asia are revised using both morphological characters and molecular data. Illustrated descriptions of the adult male Shilovia xinhuawangi sp. nov. from Xinjiang Uygur Autonomous Region of China, S. yakovlevi sp. nov. from East Kazakhstan and redescription of S. rara Makarchenko from Tajikistan and Kyrgyzstan are provided. The result of morphological study is congruent with DNA barcoding analyses using COI sequences. The average K2P interspecific nucleotide distances within S. xinhuawangi sp. nov. and S. yakovlevi sp. nov. are 0.03% and 0.3% respectively. The nucleotide distances between the two new species and S. rara can be considered interspecific. Phylogenetic analysis using Maximum likelihood (ML) and Bayesian inferences (BI) support the placement of S. xinhuawangi sp. nov. and S. yakovlevi sp. nov. within the monophyletic genus Shilovia.

摘要

使用形态特征和分子数据修订了中亚山脉的沙利奥维亚属（Diamesinae，Boreoheptagyiini）摇蚊。提供了来自中国新疆维吾尔自治区的沙利奥维亚·辛华旺吉新种、来自哈萨克斯坦东部的沙利奥维亚·雅科夫列夫新种和来自塔吉克斯坦和吉尔吉斯斯坦的沙利奥维亚·拉腊的形态学描述。形态学研究的结果与使用 COI 序列的 DNA 条形码分析一致。在沙利奥维亚·辛华旺吉新种和沙利奥维亚·雅科夫列夫新种内的平均 K2P 种间核苷酸距离分别为 0.03%和 0.3%。这两个新种与沙利奥维亚·拉腊之间的核苷酸距离可被视为种间距离。使用最大似然（ML）和贝叶斯推断（BI）的系统发育分析支持沙利奥维亚·辛华旺吉新种和沙利奥维亚·雅科夫列夫新种在单系的沙利奥维亚属内的位置。
