重庆市小唇泥蜂亚科种类调查及区系分析

Investigation and Fauna Analysis of the Subfamily Larrinae in Chongqing

通过近几年来对重庆市各区县的小唇泥蜂(Larrinae)种类资源的调查和查阅有关文献资料,共鉴定小唇泥蜂3族7属13种,属数约占中国小唇泥蜂昆虫总属数的46.67%,种数约占中国总种数的7.78%。重庆市现已知的小唇泥蜂中东洋区成分7种,跨东洋区与古北区共有成分3种,东洋、非洲区共有成分1种,东洋、古北及非洲区共有成分1种,东洋、古北及新北区共有成分1种;此外,已知种类跨中国华南与西南两区分布4种,跨华中、华南与西南3区分布4种,跨东北、华北与西南3区分布1种,跨华北、华中、华南与西南4区分布4种。调查结果显示,重庆小唇泥蜂亚科属级阶元的调查结果与中国已知属的分布特点吻合,但由于重庆生态环境特点及采集深度等因素的影响,重庆已知的各属种类数量相对较少。

In recent years, the fauna survey of the subfamily Larrinae in the family Crabronidae throughout various districts and counties in Chongqing was carried out, and the literature related to the subfamily was analyzed. As a result, 10 known species and 3 subspecies belonging to 3 tribes, 7 genera of the subfamily were identified. The number of genera and species account for about 46.67% and 7.78% of the total number of known Chinese genera and species respectively. In the fauna composition of the Larrinae species in Chongqing, there are 7 Oriental Region species, 30riental-Palearctic species, 1 Oriental-Africa species, 10riental-Palearetic-Africa species and 10riental-Palearctic-Nearetic species. Limited in Chinese zoogeographic regions, there are 4 species distributed in South China and South-West subregions, 4 species distributed in Central China, South China and South-West; 1 species in Northeast, North China and South-West; more over, 4 species distributed in North China, Central China, South China and South-West. The results show that the distribution of Larrinae genera in Chongqing and in China is consistent, because there is an influence from characteristics of the ecological environment in Chongqing, investigation depth and other factors, species of Larrinae genera in Chongqing are relatively less
