Rhacognathus americanus

University of Alberta E.H. Strickland Entomological Museum

SeasonalityThe seasonality of this species is unknown, though a single collecion from July exits in the Strickland Museum. IdentificationThis species has a prominent dark brownish-black colour that is mottled with dull yellow. It is broadly oval in shape with an elongated face; juga longer than the clypeus and touching anteriorly. This characteristic allows for easy identification from other asopine bugs, with the exception of Apatetitcus bracteatus (Fitch), which also has elongated juga; however, in the latter the juga do not meet anterior of the clypeus. The pronotum has very broad projections on both sides. The fore-femora lack the ventral tubercle present in genus Perillus Stal. Connexivum are widely exposed and are mostly dark with pale spots along the margins on each abdominal segment. It is of medium size; length 9-11 mm (Blatchley 1926).
