Migneauxia

Species within Migneauxia are distinguished from related latridiid genera primarily by subtle differences in elytral sculpture, body proportions, and male genitalia. The genus contains both larger-bodied species (e.g., M. grandis) and smaller, more compact forms. Accurate identification to species level generally requires examination of microscopic characters and dissection of male specimens.

Species in this genus inhabit environments with abundant fungal growth, including decaying plant matter, compost, leaf litter, and moist stored products. They are typically found in humid microhabitats where mold and fungal spores develop.

Documented from Denmark, Norway, and Sweden; broader distribution likely includes much of Europe given the presence of widespread species such as M. crassiuscula and M. psammeticha. Individual species show varying ranges, with some restricted to specific regions.

• LatridiusAnother genus in Latridiidae with similar small, oval body form and elytral striation; distinguished by differences in antennal club structure and pronotal shape
• EnicmusOverlaps in habitat preference and general appearance; Migneauxia species tend to have more convex body profiles and different elytral punctation patterns
