角蚜亚目的角兵蚜与大多数群居昆虫不同，它们生活在植物的开放表面。由于缺乏巢穴和其他明显的生态相关因素，目前还不清楚为什么第二宿主士兵可能已经进化。在这里，我提出了一个分子系统发育分析的32种Cerataphidini，其中包括10种属Ceratovacuna和Pseudoregma产生角士兵。进化史表明，有角的士兵进化了一次，并失去了一两次。大多数有角的士兵是一个形态上特化的种姓，两个拥有非特化士兵的物种独立地来自特化种姓的物种。Ceratovacuna属似乎经历了相对快速的辐射。将次级寄主植物和地理范围映射到昆虫发生上表明，竹子是祖先的次级寄主植物，亚洲热带和亚热带是Astegopteryx，Ceratoglyphina，Ceratovacuna Chaitoregma和Pseudoregma以及整个部落的祖先地理区域。有证据表明，在所有主要的部落谱系中，分离热带和亚热带谱系的替代事件以及一些谱系的分散。基于这些结果，我提出了角兵进化的原因和后果的假设。
The horned soldier aphids of the Cerataphidini, unlike most social insects that reside in nests, live on the open surface of plants. The lack of a nest and other obvious ecological correlates makes it unclear why secondary‐host soldiers might have evolved. Here I present a molecular phylogenetic analysis of 32 species of the Cerataphidini, including 10 species from the genera Ceratovacuna and Pseudoregma that produce horned soldiers. The phylogeny suggests that horned soldiers evolved once and were lost once or twice. Most horned soldiers are a morphologically specialized caste and two species that have unspecialized soldiers are independently derived from species with specialized castes. The genus Ceratovacuna appears to have undergone a relatively rapid radiation. Mapping secondary‐host plants and geographic ranges onto the phylogeny suggests that bamboos were the ancestral secondary‐host plants and that the Asian tropics and subtropics were the ancestral geographic regions for the genera Astegopteryx, Ceratoglyphina, Ceratovacuna Chaitoregma, and Pseudoregma and possibly for the entire tribe. There is evidence for vicariant events that separate the tropical and subtropical lineages in all of the major lineages of the tribe and for dispersal of some lineages. Based on these results, I present hypotheses for the causes and consequences of horned‐soldier evolution.
