Distribution. ARGENTINA: Misiones, Buenos Aires (NEW RECORD); BRAZIL: Santa Catarina. Male ( Fig. 1). General color and morphology as described by Thomas & Yonke (1990)for the female holotype. Measurements (n = 5): head length (1.50–1.80); width (2.10–2.25); length of antennal segments: I (0.43–0.47); II (0.59–0.62); III (0.74–0.86); IV (0.98–1.09); V (1.17–1.21); pronotum length (1.80–2.10); width (4.80–5.40); scutelum length (3.00–3.60); width (3.15–3.60); body length (7.80– 8.40); abdominal width (4.80–5.10).
Genitalia. Pygophore subquadrangular, posterolateral angles truncate. Dorsal rim subrectilinear edged by dense setae ( Fig. 2). Ventral rim sinuous, deeply excavatedmesally ( Fig. 3). Surface of ventral wall shallowly depressed between posterolateral angles, projected dorsad partially covering parameres and proctiger posteriorly ( Fig. 4). Lateral margins delimiting this depression withdense setae ( Fig. 3). Parameres long and curved, apex subtriangular ( Figs. 5, 6). Proctiger slightly bilobate at apex ( Figs. 2, 3). Phallus simple, robust, longer than wide ( Figs. 7–9). Phallotheca bearing 1+1 basal processes. Conjunctiva covering ventro-laterally the base of vesica ( Figs. 8, 9). Vesica short, dorsally bilobed ( Figs. 7, 8); ductus seminis distalis curved, surpassing apexof vesica ( Figs 7–9). Figs. 1–11. Banasa chacaThomas, 1–9 male, 10–11 female. 1, dorsal view; 2–4, pygophore, respectively dorsal, ventral, and posterior; 5–6, left paramere, lateral and mesial; 7–9, phallus, respectively dorsal, ventral, and lateral; 10, receptaculum seminis and ausenwand, ventral; 11, capsula seminalis and ductus receptaculis. aaf: anterior annular flange; ch: chitinellipsen; cj: conjunctiva; cs: capsula seminalis; di: diverticula; dr: dorsal rim; dre: ductus receptaculi; dsd: ductus seminis distalis; g9: gonapophyses 9; gc9: gonocoxites 9; la9: laterotergites 9; p: proctiger; paf: posterior annular flange; par: paramere; pi: pars intermedialis; tg9: thickening of gonapophyses 9; tvi: thickening of vaginal intima; v: vesica; vr: ventral rim; X: tenth segment. Scales: 1 = 1 mm; 2–9 = 0.5 mm; figures 5, 6 and 11 in the same scale. Female. Measurements (n = 7): head length (1.50–1.90); width (2.10–2.4); length of antennal segments: I (0.40–0.50); II (0.40–0.60); III (0.80–1.10); IV (0.10–1.11); V (1.10–1.30); pronotum length (1.60–2.10); width (4.80–5.70); scutelum length (3.10–3.90); width (3.00–3.50); body length (8.40– 9.80); abdominal width (4.60–5.60). Internal genitalia ( Figs. 10, 11). Gonapophyses 9 with 1+1 arched sclerotized areas close to elliptical ring sclerites (chitinellipsen, sensu Dupuis 1955). Thickening of the vaginal intima somewhat elliptical. Ductus receptaculi before the vesicular area subequal in lengthto this area. Pars intermedialis short, constrictedat base; anterior and posterior annularflanges directed toward ductus receptaculi. Capsula seminalis constricted at base, anterior lobe subequal in length to pars intermedialis, posterior lobe bearing two diverticula laterally directed; margin of capsula opposite to diverticula convex.
Comments. The inclusion of B. chacainto the patagiatagroup is confirmed by characteristics of male pygophore, namely ventral rim with a deep, narrow, quadrate emargination ( Figs. 3, 4, vr), and proctiger bilobate ( Figs. 2, 4, p), as well as by the presence of two diverticula at capsula seminalis in thefemale internal genitalia ( Fig. 11, di). IlexparaguariensisSaint Hilaire (Aquifoliaceae)wasfirst recorded as a host of B. chacaby Chiaradia & Milanez (2007).
