Tribe Otiocerini Muir, 1917
Genus Shellenius Ball, 1928
Type species (in original combination): Otiocerus ballii McAtee 1923.
Distribution: Widespread in US and Central America.
There are 5 species recognized in Shellenius as follows:
Shellenius ballii (McAtee, 1923) - USA: FL, IL, LA, MD, MS, OH, TN; CAN: ON
Shellenius gracilior (Fowler, 1904: 66) - Guatemala
Shellenius griseus (Fowler, 1904: 75) - Mexico (Guerrero)
Shellenius montanus (Fowler, 1904: 74) - Mexico (Guerrero), Panama
Shellenius schellenbergii (Kirby, 1821) - USA: AZ, FL, GA, IL, LA, MO, MS, NJ, NY, OH
Limited - species are seldom encountered.
Known host plants:
Derbidae are known or assumed to feed on fungal hyphae as immatures. The significance of adult host associations are unclear.
Shellenius ballii - Acer (maple, Aceraceae), Carpinus caroliniana Walter (American hornbeam, Betulaceae), Sabal palmetto (Walter) Lodd. ex Schult. & Schult. f. (cabbage palmetto, Arecaceae), Fraxinus (ash, Oleaceae)
Shellenius schellenbergii - Acer, Carpinus caroliniana, Sabal palmetto, Fraxinus
Pale, fragile forms; wings greatly exceeding the abdomen; frons extremely compressed, head strongly projecting; pustules along claval vein; clavus open, antennae with appendages; in lateral view, head projecting in front of eyes for a distance greater than width of eyes (vs. Anotia), distally rounded (vs. Otiocerus, Apache).
