一个新的蝗虫属，Armstrongium gen。 nov.，属于 Lentulidae 科（直翅目：Acridoidea：Caelifera），被指定为包含两个相当不寻常且相关的物种，即 A. viridipes 规格。十一月以及 A. pondoense 规格。十一月，这些是从南非夸祖鲁-纳塔尔省南半部的单独的本土森林栖息地收集的。除了性别二态性增强之外，由于头部形态显着不同，某些其他诊断特征和构成中的结构适应对于扁豆科来说似乎是新的。外阴上异常的副叶的存在在这个家族中是独一无二的，而雄性尾叶、副肛和外阴叶上可观察到的变化表明这些元素在交配过程中联合发挥作用，并起到额外的耦合器官的作用。描述并充分说明了两性解剖学和形态学的关键特征，同时还列出了区分物种的主要诊断特征。还提供了有关生物地理学、物候学、栖息地关联和气候的相关信息，以及各个栖息地的详细描述。
A new grasshopper genus, Armstrongium gen. nov., in the family Lentulidae (Orthoptera: Acridoidea: Caelifera), is designated for the inclusion of two rather unusual and related species, namely A. viridipes spec. nov. as well as A. pondoense spec. nov., which were collected from separate indigenous forest habitats in the southern half of KwaZulu-Natal Province, South Africa. In addition to heightened sexual dimorphism, due to strikingly dissimilar head morphology, certain other diagnostic features and structural adaptations in their make-up appear new to Lentulidae. The presence of extraordinary ancillary lobes on the epiphallus are without parallel in this family, while observable modifications to the male cerci, paraprocts and epiphallic lophi suggest that these elements act in combination and function as additional coupling organs during mating. Key characters in the anatomy and morphology in both sexes are described and fully illustrated, while the principal diagnostic characters for differentiating species are also tabled. Pertinent information on biogeography, phenology, habitat associations and climate, as well as detailed descriptions of respective habitat sites, are also provided.
