Bucephalogonia xanthophis (Berg) View in CoL
( Fig 1b View FIGURE 1 )
Additional characters of the female genitalia ( Fig 2 View FIGURE 2 ). Valvifers I ( Fig 2b View FIGURE 2 ), in lateral view, subtriangular, dorsal margin with an internal fold and scarcely more sclerotized anteriorly; apical half heavily covered by spiniform processes. Valvulae I ( Fig 2e–h View FIGURE 2 ), in lateral view, blade-shaped; shaft straight basally, with apical half curved dorsally; basal area, in lateral view, with a dorsal lobe ( Fig 2e View FIGURE 2 ) and ventral surface covered by numerous spiniform processes ( Fig 2g View FIGURE 2 ). Dorsal sculptured area (DSA) extending nearly ¾ of apical shaft, with sculpturing pattern formed by oblique filiform processes. Ventral sculptured area (VSA) less developed, formed by scale-like processes, not imbricate, becoming clearly distinct towards subapical area. Ventral interlocking device long, attaining basal half of shaft. Preapical area of blade with denticles on ventral margin, apex acute ( Figure 3h View FIGURE 3 ). Valvifers II ( Fig 2d View FIGURE 2 ), in lateral view, subrectangular shaped, with robust microsetae clustered near articulation point; posterior margin more sclerotized. Valvulae II ( Fig 2i–k View FIGURE 2 ), in lateral view, broad beyond basal curvature, with dorsal margin of shaft almost straight and bearing numerous contiguous teeth, each tooth ( Fig 2j View FIGURE 2 ) subtriangular with posterior margin declivous and longer than anterior margin, both bearing numerous rounded denticles. Preapical prominence present; apical area distinctive with margins sharpened and denticulate, apex rounded ( Fig 2k View FIGURE 2 ); ducts reaching teeth margin and apex. Gonoplacs ( Fig 2l View FIGURE 2 ), in lateral view, with basal half narrow, 0.5x longer than posterior portion, distinctly expanded; with submarginal macrosetae extending anteriorly along ventral margin; apex narrowly round.

Associated Plants. Citrus sinensis Osb. ( Remes Lenicov et al. 1999) , Vitis vinifera L. ( Ringenberg 2008), Prunus domestica L. ( Hickel et al. 2001), Coffea sp. (Garita Cambronero et al. 2008), Vernonia condensata (Baker) , Duranta repens L. ( Marucci et al. 2003), Zea mays L. ( Luft Albarracin et al. 2009), Brassica napus L. var. oleifera ( Paris et al. 2012) . New records on Allium cepa L. ( Amaryllidaceae ), Olea europaea L. var Arauco (Oleaceae) , Solanum tuberosum L. ( Solanaceae ), Tecoma stans (L.) ( Bignoniaceae ), Gossypium sp. (Malvaceae) , Baccharis sp. (Asteraceae) .
Biological data. Faunistic studies done by Remes Lenicov et al. (1999) and Dellapé et al. (2016), on citrus agroecosystems located in northeastern Argentina, showed that B. xanthophis is a predominant species throughout the year that not only occurs on citrus plants but also take refuge on weeds.
Phytosanitary importance. This species is a confirmed vector of the bacterium Xylella fastidiosa subsp. pauca in Brazil, where it is considered the most important vector in relation to its transmission capacity ( Fundecitrus 1999). B. xanthophis is also referred as a potential vector in coffee by Leite & Nunes (2003). In Argentina, screening tests on specimens collected from citrus orchards in Misiones and Entre Ríos provinces were positive for the bacterium ( de Coll et al. 2000; Dellapé et al. 2016).
