(Figs 3, 18, 28, 38, 48, 57, 58, 63)
Female macroptera. Body bicolored, brown and yellow (Fig. 3). Antennal segments brown, except for basal half of segment I and apical half of II, basal fourth and extreme apex of III and extreme bases of IV and V light brown (Fig. 18). Legs yellow. Head yellow medially and brown laterally, ocellar triangle brown (Fig. 28). Pronotum with longitudinal yellow bands medially and laterally, brown sub-laterally; mesonotum yellow with anterior and anterolateral areas brown, mesonotum yellow with posterior sub-lateral areas brown (Fig. 38). Fore wing brown, with pale circular spot at basal fourth (Fig. 48). Abdominal tergites I and X yellow, II–VIII with median oval brown area, with lateral thirds yellow, IX with median brown area and lateral, anterior and posterior thirds yellow. Ocellar triangle without sculpture, ocellar setae III long and inside the triangle; posterior area of head transversely striate with a few long reticles on extreme posterior area; mouth cone short, not surpassing prosternum. Pronotum transversely striate (Fig. 28). Mesonotum transversely striate, about 20 lines of sculpture. Metanotum transversely almost fully reticulate, except for anterior fourth with transverse lines of sculpture, internal markings absent (Fig. 38). Meso- and metafurca with spinula (Fig. 57). Abdominal tergites II–VII with around 10 transverse lines of sculpture on lateral thirds (Figs 58, 63); II–V with posteromarginal comb of microtrichia incomplete, VI with microtrichia medially and laterally and without microtrichia sublaterally, VII–VIII with complete comb of microtrichia (Fig. 63).
Measurements— holotype in microns: Body length 1375. Head length 118, width 138; pronotum length 115, width 170; fore wing length 750; antennal segments I–IX length, respectively 20, 36, 46, 50, 38, 40, 12, 10, 12.
Male. Unknown.
Etymology. The species is named after the severely deforested Atlantic Rainforest, the second-largest South American forest, where the holotype was collected.
Material studied. Female holotype: Brazil. Santa Catarina: Nova Teutônia [Seara], on leaves of Phytolacea divia, 10.xi.1949 (F.Plaumann col.) (USNM).
Comments. This species is distinctive in the genus by the metafurca with spinula and the coloration of the abdominal tergites with oval brown areas. In addition, ocellar setae III are longer than in any other Enneothrips (Fig. 28). It shares with E. amazonicus the tergite VII with complete posteromarginal comb of microtrichia (Figs 62, 63).
