Genus Otiocerus Kirby, 1821
Type species (in original combination): Otiocerus stollii Kirby 1821: 16.
Distribution: Widespread in the Nearctic (esp. south) and Central America.
There are currently 17 species recognized in this genus. Varietal forms are probably color variations, but the status of these taxa have not been recently examined.

Known host plants:
Derbidae are known or assumed to feed on fungal hyphae as immatures. The significance of adult host associations are unclear.
Otiocerus stollii - Quercus
Mostly white or yellow-themed, fragile forms; wings greatly exceeding the abdomen; frons extremely compressed, head strongly projecting; clavus open, antennae with appendages; in lateral view, dorsum of head straight (vs. sinuate in Apache) dorsal margin of wings nearly straight, demarcation between vertex and frons obtusely angular (vs. rounded in Shellenius).
Teneral specimens do not have fully developed color patterns.
