Enneothrips (Enneothripiella) flavens Moulton, 1941: 318 .

Comments. As mentioned above, E. flavens ( Figs 6, 7 ) resembles ( Figs 20, 30 , 40 , 50 , 67 ) enigmaticus ( Figs 19, 29 , 39 , 49 , 66 ) and was recorded as the key pest of peanuts for several decades. Closer examination of its biology, however, revealed that it does not breed on Arachis spp. ( Lima et al. 2022), but is oligophagous and has been found on Campomanesia guazumifolia and Adenanthera macrocarpa . Collection records show E. flavens to be found in southern and southeastern Brazil, in the states of Minas Gerais, Santa Catarina, S„o Paulo. Lima et al. (2022) provided an updated description of this species.
