中文摘要： 通过本项目研究获得了大量的研究资料和材料；揭示了该亚科昆虫在西南地区的多样性水平以及各属、种在西南地区的多样性与分布情况。 西南地区有该类群11属，占世界比例为16.2％，占全国92.3%。Episymploce属分布种类最多约为30种，占76.0%，其余各属在西南地区的分布均不超过10种；该亚科种类多分布于西南地区，华南地区次之，古北区分布很少；各地区间共有种较少，尤其是华南、西南和古北区之间，已知种大部分是地区特有种；原因可能是：1、蜚蠊物种在各地区相互隔离，各自进化，适应不同地理环境特点；2、对该类群的调查尚不能反映真实的地理分布状态。该亚科包括外群在内的14个属系统发育研究表明：该类群分为两个分支与外群并列，说明两个分支亲缘关系较远，二者关系需进一步研究；Scalida与Sigmella两属关系较远，与传统分类经验存在差异；其他属之间的关系基本符合传统观点。 对该亚科11属进行了分类研究，核对并重新描述了保存在俄罗斯、日本、英国以及中科院上海植生所的模式标本共计30种，拍摄了模式标本的特征图片；鉴定出30新种，已发表18种；厘定1属，提出1属级异名，发表相关研究论文9篇。

英文摘要： Huge amount of references and research materials were gotten through this project; diversity of Blattellinae in the southwestern region were further revealed, as well as Blattelliinae cockroach subfamily, genus and species diversity and distribution in the southwestern region. There are 11 genera of Blattelliinae cockroach were recorded from Southwest China, representing the world ratio of 16.2 percent, accounting for 92.3 percent of China. Most of species (30 species) of Episymploce distributes in this area, accounting for 76% , The other species distributiing in the southwestern region, not more than 10 species; Majority of the subfamily species are distributed in southern China, followed by southwest, Palaearctic distribution rarely;and they are less across regions, especially South China, Southwest comparing to Palaearctic; May be due to: 1. cockroach species isolated from each other in various regions, each evolution to adapt to different geographical characteristics of the environment; 2. the investigation of the taxa is not yet reflecting the true state of geographical distribution. The subfamily, including the outgroup total 14 genera used for phylogenetic studies show that: they divided into two branches, that is to say they blelong to different subfamily, but the relationship between the two needs further study; Scalida and Sigmella with distant relationship compare to that of the traditional classification of experience; the relationship between the other genera in line with the traditional point of view. There are thirty species type specimens were checked and re-descripted, which were stored in Russia , Japan, Shanghai Institute of Plant Physiology and Ecology Institute, British natural history museum, all type specimens were photographed; we revised 1 cockroach genus, proposed a genus-level synonyms Burchellia Rehn, 1933, Syn.n, and identified nearly 30 new species, of which, 18 new species were described. Nine research papers were published.
