Identification
Lochmaeocles can be distinguished from other Onciderini by a combination of morphological features typical of the tribe, including body shape and antennal characteristics. Species-level identification within the genus requires examination of specific characters such as elytral pattern, body proportions, and male . The genus name has been variously spelled in historical literature.

Life Cycle
with , larval, pupal, and stages. develop within wood, with development likely extending across multiple seasons based on observations of related wood-boring .
Behavior
are . are wood-borers that tunnel through dead wood; those of L. cornuticeps have been documented developing in branches girdled by twig-girdler (Oncideres spp.).
Ecological Role
contribute to wood decomposition by tunneling through dead branches. Some may serve as secondary inhabitants of branches initially girdled by other species.
Human Relevance
Of interest to and natural historians. Some are collected through rearing from infested wood. No significant economic impacts documented.

Rearing notes
Based on successful rearing of L. cornuticeps, wood should be collected from freshly dead branches showing minimal external signs of . Branches 1–3 inches in diameter are most productive. Rearing containers must balance moisture management to prevent mold or desiccation.
