Aconobius densus

Members of the genus Aconobius are small, compact tenebrionid beetles with a somewhat rounded body form. Aconobius densus specifically may be distinguished from congeners by subtle differences in pronotal and elytral sculpturing, though precise diagnostic features require examination of the original description. The species name "densus" (Latin for "dense" or "thick") may refer to the density of punctation or setation on the body surface. Accurate identification generally requires reference to the original description (Casey 1914) or comparison with type specimens.

Inferred from genus and family: likely inhabits arid or semi-arid regions, possibly associated with sandy or rocky substrates. Specific microhabitat preferences for this species are undocumented.

Western North America. The original description was based on material from the southwestern United States, likely California or adjacent regions. Precise locality data requires verification from the original publication.

• Aconobius parvulusCongeneric species with similar body form; differentiation requires examination of pronotal shape and elytral striation patterns.
• Other small Tenebrionidae (e.g., certain Platydema, Neomida)Similar size and general appearance; Aconobius species may be distinguished by their compact, rounded body and specific antennal structure.
