The author reports about the results of a study of Porthetinae (Pamphagidae) and other Acridoidea preserved in some European museums. The taxonomy of African Porthetinae is still poorly known; some genera were established on variable characters (e.g.: the number of the flagellum segments, the shape of the hind femora or the prosternal tubercle) and collections generally hold only few specimens of this group. These insects are characterized by a remarkable sexual dimorphism, the males generally are winged while females are apterous. Because many species were described only from one sex (sometimes the female sex), there are objective difficulties to identify them correctly. The following synonymies are proposed here: Pagopedilum Karsch, 1896 = Stolliana Bolívar, 1916; Pagopedilum brevis (Walker, 1870) = Pagopedilum martini Bolívar, 1915; Cultrinotus poultoni Bolívar, 1915 = Cultrinotus luanensis Uvarov, 1953. The male of Pagopedilum bradyanum (Saussure, 1887) and adults male and female of Pagopedilum brevis (Walker, 1870) (known only from the nymph) are described. The distinction of the genera Lobosceliana Dirsh, 1958 and Xiphoceriana Dirsh, 1958 is revealed to be very difficult and they are probably synonyms, but more material should be studied. The stridulatory system found in different genera of Porthetinae is briefly described. Further, the South African Batrachotetrix cantans Saussure, 1888 (Pamphagidae: Akicerinae) is recorded for the first time in Namibia, Barombia tuberculosa sublaevis Bolívar, 1905 (Acrididae: Catantopinae) is synonymized with B. t. tuberculosa Karsch, 1891, a probable new brachypterous species of Rhachitopis (Acrididae: Euryphyminae) is reported from Angola, the Namibian Pycnodictya herero Karny, 1910 (Acrididae: Oedipodinae) is recorded for the first time from Angola, and the Tanzanian Tmetonota dispar Miller, 1929 (Acrididae: Oedipodinae) is recorded for the first time from Kenya.
作者报告了一项对保存在一些欧洲博物馆中的牧草蝗亚科（癞蝗科）及其他蝗总科昆虫的研究结果。非洲牧草蝗亚科的分类学仍鲜为人知；一些属是基于可变特征建立的（例如：触角节数、后股节形状或前胸背板瘤），而且该类群的馆藏标本通常很少。这些昆虫具有显著的雌雄二型性，雄性通常有翅，而雌性无翅。由于许多物种仅根据一个性别（有时是雌性）进行描述，因此正确鉴定它们存在客观困难。本文提出了以下同义关系：Pagopedilum Karsch，1896 = Stolliana Bolívar，1916；Pagopedilum brevis（Walker，1870）= Pagopedilum martini Bolívar，1915；Cultrinotus poultoni Bolívar，1915 = Cultrinotus luanensis Uvarov，1953。描述了Pagopedilum bradyanum（Saussure，1887）的雄性以及Pagopedilum brevis（Walker，1870）（仅若虫已知）的成年雄性和雌性。结果表明，很难区分1958年的Lobosceliana Dirsh属和1958年的Xiphoceriana Dirsh属，它们可能是同义词，但需要研究更多材料。简要描述了在牧草蝗亚科不同属中发现的发音系统。此外，首次在纳米比亚记录到南非的鸣蝗Batrachotetrix cantans Saussure，1888（癞蝗科：阿克蝗亚科），1905年的Barombia tuberculosa sublaevis Bolívar（蝗科：斑腿蝗亚科）与1891年的B. t. tuberculosa Karsch同义，报道了安哥拉一种可能的新的短翅型拉氏蝗属（Rhachitopis）物种（蝗科：阔颊蝗亚科），首次在安哥拉记录到纳米比亚的赫氏密点蝗Pycnodictya herero Karny，1910（蝗科：斑翅蝗亚科），以及首次在肯尼亚记录到坦桑尼亚的异色短角蝗Tmetonota dispar Miller，1929（蝗科：斑翅蝗亚科）。
