Popis: Dilobopterus costalimai Young (Fig 1d) Female genitalia (Fig 3a–m). Female sternite VII (Fig 3a), in ventral view, subrectangular, median length 0.6x its maximum wide; lateral margins slightly convergent posteriorly and posterior margin with a small median lobe slightly concave centrally; surface with scattered microsetae. Sternite VIII (Fig 3b) partially membranous, with median and lateral areas more sclerotized. Pygofer (Fig 3c), in lateral view, posterior margin moderately projected; surface almost entirely covered by numerous macrosetae, with scattered microsetae. First valvifer (Fig 3d), in lateral view, rhomboid; posterior half with numerous microsetae. Valvulae I (Fig 3f), in lateral view, blade-shaped, shaft widened towards apex and basal area curved dorsally; with a conspicuous fold along ventral margin, with sculpturing pattern formed by rectilinear processes, arranged horizontally. (DSA) extending nearly 2/3 of apical shaft, with sculpturing pattern formed by filiform processes arranged obliquely; (VSA) less developed, formed by scale-like processes limited to subapical area; preapical portion gradually tapered to round apex, with denticulate margins. Second valvifer (Fig 3e) in lateral view, subtriangular, anterior margin heavily sclerotized. Second valvulae (Fig 3i, k), in lateral view, broad beyond basal curvature, dorsal margin declivous towards apex and ventral margin straight. Dorsal margin of shaft bearing numerous not spaced teeth, each tooth subtriangular with numerous denticles on both margins, anterior and posterior (Fig 3j); preapical prominence present (Fig 3k). Gonoplacs (Fig 3m), in lateral view, anterior portion narrow as long as the posterior portion which is markedly expanded; fine submarginal macrosetae along ventral margin; apex widely rounded. Distribution. Argentina: Misiones, Corrientes (Young 1977). New records: Jujuy (Yuto) . Associated plants. Citrus sinensis (Remes Lenicov et al. 1999), Coffea arabica L. (Marucci et al. 2001), Vernonia condensata (Milanez et al. 2001). Biological data. Studies conducted on C. sinensis probed that this sharpshooter feeds mainly on new shoots and leaves (Marucci et al. 2004). With respect to oviposition, D. costalimai lays eggs in isolation on leaf epidermis along the ribs of new leaves (Fundecitrus 1999). It is one of the most abundant species on northeastern Argentinean citrus plants. Phytosanitary importance. Confirmed vector of Xylella fastidiosa subsp. pauca in plants of Citrus sinensis (L.) Osb. and Coffea arabica L. from Brazil (Marucci et al. 2008).
