Economic Importance

Species are seldom encountered, but the type species of this genus was found on Coconut during a survey of possible phytoplasma vectors.

Plant associations

Litophallus schellenbergiiAcer, Carpinus caroliniana, Sabal palmetto, Fraxinus (“on ash” in Spooner 1937)
Litophallus inornatus – Coconut palm (Cocos nucifera L.).

Recognition

A key to genus was provided in Bahder et al. (2025).

Description of S. schellenbergii from Kirby 1821: 18:

Schellenbergii. 7. O. pallidus, capite sanguineo, elytris absque vasis roseis.

[female]
Long. corp. lin. 2.
Expans. alar. lin. 7-1/4

Corpus pallidum. Caput oblongum, sanguineum : rostro obtusion vix ascendenti ; carinis superioribus approximatis niveis,inferioribus

Diagnosis from Bahder et al. (2025)

“Medium-sized. Head in lateral view broad, lachrymiform or broadly rounded and projected for distance
greater than maximum width of eye; head broader than long (length 0.5–0.8x greatest width); vertex convex, apex
rounded. Vertex narrowly triangular, lateral margins in contact at head apex, disc deeply concave (median carina
obsolete). Frons strongly narrowed with lateral margins in close contact for entire length. Pits on lateral margins
of vertex and frons. Lateral ocelli obscure or absent. Antennae with scape bearing elongated curved projection
(projection shorter than antennal length), pedicel elongated and curved, about 3x longer than scape. Apex of rostrum
reaching hind coxae, apical segment short (about as wide as long). Composite vein reaching CuP before wing
margin (i.e., clavus open), C5 cell (i.e., procubital cell) closed. Stridulatory plate on trailing margin of hindwing
small, with concave external margin. Hind tibia lacking lateral spines, second tarsal segment bearing two apical
spines. Hind tibial spinulation 4–(4–5)–2. Aedeagal shaft straight, lacking processes, endosoma simple (lacking
processes in type species).”

Collecting

Found infrequently, like many Otiocerini, occasionally at (or near) lights, or on the underside of leaves. Litophallus inornatus was found sweeping coconut fronds (inspection may be more effective)
