Phaea rufiventris is a species of longhorn beetle belonging to the family Cerambycidae, subfamily Lamiinae. These beetles are characterized by their typically long antennae, which can often be longer than their body. The specific epithet "rufiventris" is derived from Latin, meaning "red belly," which points to a distinguishing characteristic of this species.

Description
Phaea rufiventris is generally a slender-bodied beetle. While specific dimensions can vary, species within the genus Phaea are typically small to medium-sized longhorn beetles. As implied by its name, a key diagnostic feature of P. rufiventris is the presence of a reddish coloration on its ventral (underside) abdomen, which contrasts with its typically darker dorsal (upper) surface, often dark brown or black. Like other longhorn beetles, it possesses prominent antennae that are often elongated.
Distribution
Species of the genus Phaea are primarily found in the Neotropical realm, encompassing Central and South America. Phaea rufiventris itself is known to inhabit regions within this broad geographic area, though precise distribution data can be localized to specific countries or even sub-regions depending on documented collections.
Ecology and Biology
As with many other members of the Cerambycidae family, the larvae of Phaea rufiventris are wood-borers. They typically develop within the wood of various host trees, often feeding on dead, decaying, or sometimes live timber. This larval stage can last for an extended period, contributing to the decomposition of wood in their ecosystems. Adult beetles are typically short-lived. While specific adult feeding habits for P. rufiventris are not extensively documented, adult longhorn beetles may feed on pollen, nectar, tree sap, or occasionally foliage, though some species do not feed extensively as adults. Their role in the ecosystem includes nutrient cycling through wood degradation and serving as a food source for insectivorous animals.
