Genus Shellenius Ball, 1928
[Back to North American Derbidae]
Family Derbidae Spinola, 1839
Subfamily Otiocerinae Muir, 1917
Tribe Otiocerini Muir, 1917
Genus Shellenius Ball, 1928
Type species (in original combination): Otiocerus ballii McAtee 1923.
Widespread in US and Central America.
There are 5 species recognized in Shellenius as follows [See Metcalf 1945: 185]:
- Shellenius ballii (McAtee, 1923: 45) – USA: FL, IL, LA, MD, MS, OH, TN; CAN: ON (Bugguide adds Quebec and South Carolina)
- Shellenius gracilior (Fowler, 1904: 76) – Guatemala
- Shellenius griseus (Fowler, 1904: 75) – Mexico (Guerrero)
- Shellenius montanus (Fowler, 1904: 74) – Mexico (Guerrero), Panama
- Shellenius schellenbergii (Kirby, 1821: 18) – USA: AZ, FL, GA, IL, LA, MO, MS, NJ, NY, OH (Bugguide adds AL, WV)
Limited – species are seldom encountered.
Derbidae are known or assumed to feed on fungal hyphae as immatures. The significance of adult host associations are unclear. Hosts from Wilson et al. 1994 (also check FLOW, although no additional hosts as of 20 June 2017); plant names from USDA PLANTS or Tropicos.
- 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 (“on ash” in Spooner 1937)
Pale, fragile forms; wings greatly exceeding the abdomen (forewings rater narrow); frons extremely compressed, head strongly projecting; pustules along claval vein; clavus open, antennae with appendages; antennae with appendages; in lateral view, head projecting in front of eyes for a distance greater than width of eyes (vs. Anotia), dorsal and ventral margins approximately straight, rounded at apex (vs. Otiocerus, Apache).
After review of McAtee (1923), it appears that I have had these two species backwards, something Lois O’Brien tried to tell me (consequently, they may be backwards in Bartlett et al. 2011). Have corrected that below.
Description of S. schellenbergii from Kirby 1821: 18:
Schellenbergii. 7. O. pallidus, capite sanguineo, elytris absque vasis roseis.
Corpus pallidum. Caput oblongum, sanguineum : rostro obtusion vix ascendenti ; carinis superioribus approximatis niveis,inferioribus
McAtee (1923) In his key (to Otiocerus), characterized schellenbergii as ‘without distinct red or dark markings other than veins, [tegmina] lutescent, veins red’ and balli as ‘with distinct red or dark markings other than veins; with dark markings (sometimes red also); markings extensive, ‘cheifly’ in the form of spots; spots irregular in shape, aggregated, covering most of tegmen except clavus’
