【摘要】 多距石蛾科Polycentropodidae是毛翅目Trichoptera中较大的科，隶属于环须亚目Annulipalpia、纹石蛾总科Hydropsychoidea。在本研究之前世界已知约605种（隶属于2亚科、20属），分布于世界各动物地理区。 本科成虫区别于其他科的主要鉴别特征为：下颚须5节，末节长至少为第4节长的2倍。前胸背板窄小，中胸盾片具一对互相接近的小毛瘤，前足胫节具端前距，后足胫节内距圆锥形，前翅R₁不分叉。 多距石蛾幼虫生活于水中，广泛分布于各种清洁的流水和静水栖境中，由于不同种类对水体环境的敏感性各不相同，可作为溪流、河流、湖泊和池塘等水体水质监测的指示生物。 本研究依据采自于中国17省市自治区标本的观测，分别对多距石蛾科5属64种作了详细形态描述，同时对所有中国旧有记录进行了厘定，共记录了中国多距石蛾科81种，隶属于1亚科6属，其中包括30个新种(圆叶缺叉多距石蛾Polyplectropus rotundifolius sp．nov．，三歧缺叉多距石蛾Polyplectropus trifurcatus sp．nov．，三角缺叉多距石蛾Polyplectropus trigonius sp．nov．，钩状缺叉多距石蛾Polyplectropus unciformis sp．nov．，指状缺叉多距石蛾Polyplectropus digitaliformis sp．nov．，具针缺叉多距石蛾Polyplectropus aciculatus sp．nov．，肘肢缺叉多距石蛾Polyplectropus cubitalis sp．nov．，柱肢缺叉多距石蛾Polyplectropus subteres sp．nov．，端截缺叉多距石蛾Polyplectropus truncatulus Zhong，Yang and Morse，sp．nov．，端突缺叉多距石蛾Polyplectropus convexus Zhong，Yang and Morse，sp．nov．，斧端缺叉多距石蛾Polyplectropus dolabriformis Zhong，Yang and Morse，sp．nov．，颚状缺叉多距石蛾Polyplectropus mandibuliformis Zhong，Yang and Morse，sp．nov．，距枝缺叉多距石蛾Polyplectropus rectangulus Zhong，Yang and Morse，sp．nov．，喙端缺叉多距石蛾Polyplectropus rostriformis Zhong，Yang and Morse，sp．nov．，扇形缺叉多距石蛾Polyplectropus flabllifolius sp．nov．，具齿缺叉多距石蛾Polyplectropus dentatus sp．nov．，三角缘脉多更多还原

【Abstract】 In present thesis, 81 species in 6 genera of the single recorded subfamily Polycentropodinae from China of the tricopteran family Polycentropodidae are listed and checked, their distribution characteristic is discussed as well. Among them, 64 species including 30 new to science and 7 new records to China are described and figured. Specially, the biogeography of two genera Cernotina Ross (new record to China) and Polyplcetropus Ulmer are discussed too, their distribution show a circle-Pacific pattern. In addition, 3 new species groups in the genus Polyplcetropus Ulmer and I in Plectrocnemia Stephen are recognized and suggested, the phylogeny between 5 apecies groups of the former genus is reconstructed in particular. Further, keys to all genera as well as species in the family of China are provided.All specimens in this study including types are deposited in the Insect Collection of Nanjing Agricultural University, China, except one Cernotina sinensis sp. nov. male in Clemson University Arthropod Collection, South Carolina, USA.Polycentropodinae Ulmer, 1903更多还原
