Pantomorus includes several Neotropical species that have lost humeri and hind wings (they are flightless). They are common in treeless areas where they usually reproduce by parthenogenesis, same as those of the generaAramigus and Atrichonotus.
Pantomorus auripes is similar to P. prasinus in size, shape of body and vestiture, which is composed on green-golden scales and suberect setae, longer near the apex of the elytra. It belongs to the P. auripes species group, revised by Lanteri et al. (1991).
The species is probably parthenogenetic (Lanteri 1995b, Lanteri & Normark 1995) and is infected with the bacterium Wolbachia, which induces this kind of reproduction in several groups of insects (Rodriguero et al. 2010a).
The analysis of potential distribution suggests that could colonize other countries outside its native range of distribution, especially South Africa and southeastern Australia (Lanteri et al. 2013b).
Associated with vegetation typical of Pampean and Espinal biogeographic provinces, such as Baccharis salicifolia (Ruiz & Pav.) Pers (= chilca) and Wedelia glauca (Ort) Hoffm ex Ilicken (= sunchillo) (Asteraceae) (Lanteri et al. 2002a). The latter is a weed toxic for cattle, broadly distributed in southern Brazil, Uruguay and Argentina, down to the Río Colorado river.
In Argentina it causes damage in Helianthus annuus L. (Asteraceae), Medicago sativa L. (Fabaceae) and Solanum tuberosum L. (Solanaceae) (Lanteri 1994, Lanteri et al. 2002a) and in Brazil, inLycopersicum esculentum Mill. (Solanaceae) (Silva et al. 1968).
