AppearanceHesus cordatus is set off from other species in the genus, especially from the similar looking species H. humeralis by having the basal part of the third antennal segment ochraceous and having two pale rings on the tibia (unicolorous in H. humeralis).
NamingThe species was first described in 1803 by Fabricius as Aradus cordatus. Later the type species for the genus Hesus, (Hesus annuliger Stål, 1862 ) was synonymized with cordatus, so effectively it is now also the type species (officially not, of course). Species sunk into synonymy with H. cordatus include:
Hesus annuliger Stål, 1862 (Mexico)
Crimia cincticornis Walker, 1873 (Brazil)
Hesus semiolus Bergroth, 1894 (Brazil)
DistributionThe species has a wide distribution range throughout Central and South America, having been recorded from Mexico, Costa Rica, Nicaragua, French Guyana, Brazil, Ecuador, Colombia and Peru.
