Cosmosycanus, a new genus of harpactorine assassin bug established for Agriosphodrus perelegans (Heteroptera: Reduviidae)

A new monotypic genus Cosmosycanus is established for Agriosphodrus perelegans Breddin, 1903. This genus is separable from Agriosphodrus Stål, 1867 by the head being much longer than the pronotum, and the posterior pronotal lobe lacking a median depression. The new genus is also distinguished from Sycanus Amyot and Serville, 1843 by the smooth posterior pronotal lobe and the unspined and non‐tuberculate scutellum. The type species, Cosmosycanus perelegans, comb. nov. is redescribed and considered the senior synonym of Sycanus elongatulus Distant, 1919.     

北京维管植物三十年之变化

植物名称是人类对植物研究与利用等活动的基础。植物名称的变化可能成为不同行业之间交流的障碍, 错误或含混的植物名称可能会造成不便甚至损失。北京作为中国的首都, 在生物多样性保护与生态文明建设的背景下, 对于植物多样性信息变化的管理水平和能力要求更高。及时并准确地更新植物名称的变化及其过程, 对于植物学工作者、园林工作者和与植物相关产业从业者都十分重要。本文基于过去30年间(1992‒2021年)北京各类维管植物的名称信息, 记录了自1993年《北京植物志》(1992年修订版)以来的维管植物名称的变化过程: 包括34个新类群、175个新记录、509个新异名, 49个错误鉴定, 以及50个存疑类群。过去30年间, 北京的维管植物发生了很大的变化。本文结果可作为北京维管植物多样性监测和保护的重要参考。
