尽管它在Indomalayan地区的Myrmicinae中相对较大，但Paratopula惠勒的收集事件很少。本文讨论了在香港发现的拟石蛾属，并提出拟石蛾属（Paratopula bauhinia sp. nov）为一新种。这一增加使该属的全球描述的物种数量达到12种，其中4种只知道来自生殖种姓。羊蹄甲拟盾介壳虫，新种可以通过以下特征的组合来与先前描述的物种区分：下颌骨咀嚼边缘上的10个齿，顶部尖锐的毛，前胸背板前缘的圆形中间部分，后叶柄宽于长，直，钝的propodeal刺。本文提供了一个修订后的八种副托普拉虫的分类检索表。此外，首次描述了狭叶轮甲博尔顿的雌性种姓。这两个属的稀有性也讨论了他们潜在的夜间和树栖习性的基础上。
Despite its relatively large size among the Myrmicinae of the Indomalayan region, collection events of Paratopula Wheeler are rare. Here we discuss the discovery of Paratopula in Hong Kong and present Paratopula bauhinia sp. nov as a new species. This addition brings the number of globally described species for the genus to twelve species, four of which are known only from the reproductive caste. Paratopula bauhinia sp. nov . can be distinguished from previously described species by the combination of the following features: 10 teeth on the masticatory margin of mandibles, apically acute hairs, a rounded median portion of the anterior margin of the pronotum, postpetiole broader than long, and straight, blunt propodeal spines. A revised key for the eight species of Paratopula known from the worker caste is provided. Additionally, the female caste of Rotastruma stenoceps Bolton is described for the first time. The rarity of these two genera are also discussed on the basis of their potentially nocturnal and arboreal habits.
