ABSTRACT The Neotropical Region or Neotropics, contains vast expanses of rain forest and river systems representing some of the most biologically diverse ecosystems on Earth, but much of its resident biota remains undescribed and undocumented, and some of it is at risk of extirpation and extinction. Anthropogenic disturbances, especially deforestation, urbanization, and climate change, threaten the integrity of the Neotropics and its biodiversity. In the Neotropics, freshwater habitats are particularly susceptible to environmental stressors and freshwater species throughout the Neotropics have experienced marked declines greater than those of other groups when compared to marine and terrestrial systems. Advances in taxonomic descriptions, preparation of keys, and faunal assessments will aid future studies as well as conservation efforts.

新热带地区水生昆虫系统学和生物多样性研究进展：引言

摘要 新热带地区或新热带地区包含大片雨林和河流系统，代表地球上一些生物多样性最丰富的生态系统，但其大部分常驻生物群仍未得到描述和记录，其中一些处于灭绝和灭绝的危险之中。人为干扰，尤其是森林砍伐、城市化和气候变化，威胁着新热带地区及其生物多样性的完整性。在新热带地区，淡水栖息地特别容易受到环境压力因素的影响，与海洋和陆地系统相比，整个新热带地区的淡水物种经历了比其他群体更大的下降幅度。分类描述、密钥准备和动物群评估方面的进展将有助于未来的研究和保护工作。
