Cerataphidini is a taxonomic tribe of aphids within the family Aphididae (order Hemiptera, suborder Sternorrhyncha). Members of this tribe are characterised by their association with the external surfaces of host plants rather than residing in concealed nests. The tribe is primarily distributed in subtropical and tropical regions of Southeast Asia, including the Malay Peninsula and the island of Sulawesi.
Taxonomy
- Kingdom: Animalia

- Class: Insecta
- Order: Hemiptera
- Suborder: Sternorrhyncha
- Superfamily: Aphidoidea
- Family: Aphididae
- Tribe: Cerataphidini
Morphology and Behavior
- Species in Cerataphidini are often referred to as “horned soldier aphids” because many possess prominent corniform (horn‑like) extensions on their bodies.
- Unlike many other aphid groups that form protective colonies or nest within plant tissues, cerataphidines typically inhabit the exposed surfaces of leaves and stems.
- Some taxa exhibit a caste‑like division of labor, with “soldier” morphs defending colonies against predators, a behavior documented for members of this tribe.
Geographic Distribution
- The tribe is most diverse in the humid, warm climates of Southeast Asia. Documented records highlight its prevalence in the Malay Peninsula, as well as on the island of Sulawesi in Indonesia.
Biodiversity and Observation Records
- As of the latest publicly available data, the citizen‑science platform iNaturalist lists 619 observations of Cerataphidini species, indicating a moderate level of documentation by naturalists and researchers.
Research and Literature
- Phylogenetic studies have addressed the evolutionary relationships within Cerataphidini, contributing to a better understanding of its placement among aphid lineages.
- The tribe’s distinctive ecological niche—occupying open plant surfaces rather than concealed nests—has been highlighted in entomological literature as an example of ecological diversification among aphids.
