Definition
Hycleus rouxi is a taxonomic name that has been used to refer to a species of blister beetle belonging to the family Meloidae and the genus Hycleus.
Overview
The genus Hycleus comprises numerous species of Meloidae that are distributed throughout the Old World, especially in the Palearctic and Afrotropical regions. Members of this genus are commonly known as “blister beetles” because many produce a toxic compound called cantharidin, which can cause skin irritation. The specific epithet rouxi has historically been applied to a distinct species within this genus, but detailed information regarding its distribution, ecology, and morphology is scarce in readily accessible scientific literature.
Etymology / Origin
The species name rouxi is likely an eponym honoring a person with the surname Roux, a common practice in zoological nomenclature. The original describer of the species (often cited as “Pic” or another early 20th‑century entomologist) assigned the name in recognition of that individual’s contributions or collection of the specimen.
Characteristics
Accurate information is not confirmed.
General characteristics of Hycleus species include:
- Elongated, soft-bodied adults ranging from 5 to 20 mm in length.
- Brightly colored or patterned elytra, often with contrasting spots or bands.
- A pronotum that is usually wider than the head and may possess lateral margins.
- Antennae that are filiform with 11 segments.
Because species‑specific descriptions for Hycleus rouxi are not readily available in major taxonomic databases or recent revisions, any detailed morphological traits, life cycle, host plant associations, or precise geographic range remain unverified.

Note: The absence of comprehensive, peer‑reviewed information on Hycleus rouxi limits the ability to present a full encyclopedic entry. Further research in specialized entomological literature, museum collections, or taxonomic monographs would be required to confirm the species’ validity and detailed attributes.
