Definition
Agelasta annamensis is a species of beetle belonging to the family Cerambycidae, commonly known as longhorn beetles.
Overview
The species was formally described by entomologist Stephan von Breuning in 1956. It is recorded from Vietnam, where the type locality is associated with the historical region of Annam (central Vietnam). As a member of the genus Agelasta, it is part of a group of small to medium‑sized cerambycids that are predominantly distributed in East and Southeast Asia.
Etymology / Origin
The specific epithet annamensis is derived from “Annam,” the former name for a central area of Vietnam. The suffix “‑ensis” denotes belonging to or originating from that region, indicating the species’ geographic association.
