Eustrophopsis ornatus
(VanDyke, 1928)
Eustrophopsis ornatus is a of in the Tetratomidae, described by VanDyke in 1928. This species belongs to a small family of beetles sometimes referred to as polypore fungus beetles or false darkling beetles. The Eustrophopsis is part of a group of beetles associated with fungal , particularly wood-decaying fungi. Information regarding the specific and of this species remains limited in published literature.

Identification
No specific diagnostic features for distinguishing Eustrophopsis ornatus from or similar tetratomids are documented in the available sources. The Tetratomidae is characterized by elongate-oval to oblong body form, , and with five visible segments on all legs. -level identification within Eustrophopsis requires examination of subtle morphological characters including pronotal and elytral , antennal proportions, and male genitalia.
Habitat
Based on -level characteristics, Eustrophopsis ornatus likely inhabits forested environments where decaying wood and fungal growth occur. Tetratomidae are generally associated with polypore fungi and decaying wood, though specific microhabitat preferences for this are not documented.
Distribution
Records indicate presence in Middle America and North America. The exact range within these regions is not specified in available sources.
Ecological Role
As a member of Tetratomidae, this likely contributes to nutrient cycling in forest through association with wood-decaying fungi. The precise ecological function of E. ornatus has not been studied.
Similar Taxa
- Eustrophopsis bicolorCongeneric that would share similar body plan and preferences, requiring careful examination of coloration and elytral punctation for separation
- TetratomaRelated within Tetratomidae with similar and ecological associations; distinguished by differences in antennal structure and body proportions

Taxonomic note
The Tetratomidae has undergone taxonomic revision, with some authorities previously placing these beetles within Melandryidae or Tenebrionidae. Current classification recognizes Tetratomidae as a distinct family within Cucujiformia.
Data limitations
This is represented by only a single observation in iNaturalist, indicating it is either genuinely rare, under-collected, or difficult to detect due to its cryptic habits associated with fungi and decaying wood.
