Xestocoris tibialis
This record describes Xestocoris tibialis (species). Recorded family: Rhyparochromidae. Recorded order: Hemiptera.
Identification and Appearance
Male readily distinguished by the greatly expanded fore tibiae. Based on details in O'Donnell's redescription of both X. tibialis and X. nitens , the females of X. nitens may be distinguished by the more obscure outer border of the clavus (marked by clear line of punctures in X. nitens ); the shorter scutellum relative to length of claval commissure (0.56:0.56 vs. 0.68:0.40 in X. nitens ); and a narrower vestigial membrane (membrane present only as a small triangular flap vs. membrane reduced to a broadly rounded flap extending to level of apex of corium in X. nitens ).

About True Bugs, Cicadas, Hoppers, Aphids and Allies: the wider group
Order-level background for Hemiptera, the group containing Xestocoris tibialis. Species-specific details appear above.
Group overview
Hemiptera (true bugs) includes over 80,000 described species across cicadas, aphids, leafhoppers, shield bugs, and bed bugs. Aphids alone cost global agriculture an estimated $2.5 billion annually in crop losses.
Ecological role of the group
Many Hemiptera are essential food sources for birds and predatory insects. Cicadas provide massive nutrient pulses during emergence events - a single Brood X emergence can involve trillions of individuals across 15 states.
Economic and practical significance of the group
The brown marmorated stink bug (Halyomorpha halys) caused $37 million in apple crop losses in a single year in the U.S. Mid-Atlantic region. Bed bug infestations in the U.S. increased by 500% between 2001-2010, costing the hotel industry hundreds of millions annually.
Recorded sources for this group: USDA, EPA, University research. Imported estimates may describe particular regions or reporting periods.
