Phryneta coeca is a species of longhorn beetle belonging to the family Cerambycidae, subfamily Lamiinae. It was first formally described by the German entomologist Karl Hintz in 1919.

Description
Phryneta coeca, like other members of the Cerambycidae family, is characterized by its generally elongated body and typically long antennae, which often exceed the length of its body. The specific epithet "coeca" (from Latin caeca, meaning "blind") indicates a distinctive feature of this species: it possesses significantly reduced or vestigial eyes. This adaptation differentiates it from many other longhorn beetles that typically have well-developed compound eyes.Members of the genus Phryneta are often robust, relatively large beetles with sturdy bodies, and may exhibit cryptic coloration (mottled patterns of brown, grey, or black) that provides camouflage against tree bark. Larvae of longhorn beetles are xylophagous, meaning they bore into and feed on wood.
Distribution and Habitat
This species is native to various parts of East and Southern Africa. Recorded occurrences include countries such as Tanzania, Mozambique, the Democratic Republic of Congo, Kenya, and South Africa. Its natural habitat includes forested or wooded environments where host trees for its wood-boring larvae are abundant. Adult beetles may be found on or near their host plants, potentially feeding on sap, pollen, or foliage.Etymology
The specific epithet coeca (or caeca) is derived from the Latin word meaning "blind." This denomination is applied to species that exhibit reduced or absent visual organs. In the case of Phryneta coeca, it points to the particularly small or non-functional eyes, which can be an adaptation for species living in dimly lit environments (such as within wood or under bark) or those that rely more heavily on tactile and chemosensory cues for navigation and foraging.References
