Omalorphanus
Campbell & Chandler, 1987
Omalorphanus is a of () described in 1987 from the H.J. Andrews Experimental Forest in Oregon. The sole , Omalorphanus aenigma, was noted by its authors for possessing multiple unusual morphological features that complicated its taxonomic placement. The genus was ultimately assigned to Omaliinae based on its distinctive defense gland structure and arrangement.

Identification
The is characterized by a unique and complex omaliine- defense gland on 8, along with distinct on tergites 2–6. These features were considered unusual enough that Campbell and Chandler described the as having 'a number of unusual morphological features' that made placement difficult.
Habitat
Known from montane forest at elevations of 1,100–1,200 meters (3,500–4,000 feet) in the H.J. Andrews Experimental Forest, Oregon.
Distribution
Known only from the locality in the H.J. Andrews Experimental Forest, Oregon, USA.
Behavior
Possesses a defense gland on 8 that emits an offensive secretion or vapor to repel enemies.
Similar Taxa
- Microsilphinae (as tribe or subfamily)Shared characteristics of the defense gland and arrangement initially suggested possible placement in this group, though Microsilphinae was restricted to southern hemisphere .
- EmpelinaeThe omaliine- defense gland and features also limited possible placement to this , though the single was unknown to the authors.

Type locality
The H.J. Andrews Experimental Forest is a long-term ecological research site in the Cascade Range of Oregon, suggesting the may be associated with mature coniferous forest .
