Placosternus is a genus of beetles in the family Cerambycidae, containing the following species: [1]
Beetles are a group of insects that form the order Coleoptera, in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently. The largest of all families, the Curculionidae (weevils) with some 80,000 member species, belongs to this order. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops.

Placosternus crinicornis is a species of beetle in the family Cerambycidae. It was described by Chevrolat in 1860.
Placosternus difficilis, commonly known as the Mesquite Borer, is a wood boring longhorn beetle which resembles a black and yellow wasp. Larvae of mesquite borers are deposited in mesquite trees. It has been seen to be attracted to mesquite trees when there is freshly cut or broken limbs and logs. Adults use nectar and pollen as a food source.
Placosternus erythropus is a species of beetle in the family Cerambycidae. It was described by Chevrolat in 1835.
