Definition
Oberea shirakii is a species of beetle belonging to the family Cerambycidae, commonly known as longhorn beetles. It is classified within the genus Oberea, which comprises slender, wood‑boring insects.
Overview
The species was formally described in the mid‑20th century and is recorded from East Asia, with confirmed occurrences in Japan and Taiwan. Like other members of its genus, O. shirakii is associated with woody plants, where its larvae develop within stems or branches. Adult beetles are typically active during the warmer months, but detailed phenology and ecological interactions for this specific species have not been extensively documented in the scientific literature.
Etymology / Origin
The specific epithet shirakii honors an individual bearing the surname Shiraki, presumably a contributor to entomology or the collector of the type specimen. The practice of naming species after persons is common in taxonomic nomenclature, but the exact identity of the honoree is not definitively recorded in accessible sources.
Characteristics
- Morphology: Oberea species are characterized by elongated bodies and relatively long antennae, often exceeding the body length. O. shirakii conforms to this general body plan; however, precise measurements, coloration patterns, and distinguishing morphological traits are not detailed in widely available references.
- Life Cycle: The life cycle likely mirrors that of congeners, involving egg deposition in plant tissue, larval boring and feeding within stems, pupation inside the host, and emergence of the adult beetle.
- Habitat: Recorded from forested or semi‑urban habitats where suitable host plants are present. Specific host plant species for O. shirakii are not conclusively identified in the literature.

Note: While the existence of Oberea shirakii as a taxonomic entity is supported by catalogues of Cerambycidae, specific biological and ecological details remain limited in publicly accessible sources. Accurate information on its precise distribution, host preferences, and morphological diagnostics is not confirmed.
