报道了采自南非夸祖鲁-纳塔尔的四种新蝗总科昆虫。一新属，Silvanidiella gen.nov.，是为了适应两个新的小型物种，S. amazulu spec. nov.和S. griqua spec. nov.另外，还发现了另一个独特的单型新属Pondoidium gen. nov.，以P.trilineatum spec. nov.为属型，并记述了采自祖鲁兰中部的另一新种S. Margaretae spec. nov.，与最近建立的森林属Silvanidium Brown，2012年一致。所有这些类群都具有典型的雕刻面部形态，也显示出强烈的两性异形，这表明与长期建立的核心属Eremidium Karsch，1896的亲缘关系。突出的解剖和生殖特征，特别是在男性的情况下，进行了描述和充分说明，而临时的关键用于区分新的类群。介绍了关于植物地理学、物候学、生境关系和气候方面的现有资料，以及实地收集的数据和已知的分布情况。
Four new Acridoidea in the family Lentulidae from KwaZulu-Natal, South Africa, are described as new to science. A new genus, Silvanidiella gen.nov., is erected to accommodate two diminutive new species, S. amazulu spec. nov. and S. griqua spec. nov. In addition, another distinctive monotypic new genus, Pondoidium gen. nov., with P. trilineatum spec. nov. as its generotype, is described, as is another new species from central Zululand, S. margaretae spec. nov., referable to the recently established sylvan genus Silvanidium Brown, 2012. All these taxa possess characteristically sculptured facial morphology and also display strong sexual dimorphism, suggesting affinities with the long-established core genus Eremidium Karsch, 1896. Salient anatomical and genitalic characters, especially in the case of males, are described and fully illustrated, while provisional keys for differentiating the new taxa are provided. Available information on biogeography, phenology, habitat association and climate aspects, together with field collection data and known distribution, is presented.
