The European species Nigrobaetis gracilis (Bogoescu & Tabacaru 1957) and more than 19 Asian and African species of Nigrobaetis Kazlauskas (in Novikova & Kluge) 1987 belong to the subgenus Margobaetis Kang & Yang 1994, which is characterized by peculiar asymmetric eggs and narrow paraglossa of larval labium. A new synonymy is established: Nigrobaetis (Margobaetis) minutus (Mller-Liebenau 1984) = N. paramakalyani Kubendran & Balasubramanian in Kubendran et al. 2015 = N. sumbensis Kaltenbach & Gattolliat 2023, synn.n.; winged stages (male and female imagines and subimagines) and eggs of this species are described for the first time. N. (M.) minutus is widely distributed on Oriental Region, being revealed in West Malaysia, Southern India, Sumba and Sulawesi islands in Indonesia. Winged stages (male and female imagines and subimagines) and eggs of Nigrobaetis (Margobaetis) klugei Sivaruban et al. 2022 are described for the first time.
欧洲物种 Gracilis nigrobaetis（Bogoescu 和 Tabacaru 1957）以及超过 19 种亚洲和非洲的 Nigrobaetis Kazlauskas（在 Novikova 和 Kluge 中）1987 属于 Margobaetis Kang 和 Yang 1994 的亚属，其特征是特殊的不对称卵和幼虫下唇的狭窄侧舌。建立了一个新的同义词：Nigrobaetis（Margobaetis）minutus（Müller-Liebenau 1984）=N. paramakalyani Kubendran 和 Balasubramanian 在 Kubendran 等人中。2015 = N. sumbensis Kaltenbach 和 Gattolliat 2023，synn.n.；该物种的有翅阶段（雄性和雌性成虫和若虫）和卵首次被描述。N.（M.）minutus 在东洋区广泛分布，在西马来西亚、印度南部、苏门答腊和印度尼西亚苏拉威西岛都有发现。Nigrobaetis（Margobaetis）klugei Sivaruban 等人的有翅阶段（雄性和雌性成虫和若虫）和卵。2022 年首次被描述。
