Diagnosis. Mesonotum ( Fig. 2A View FIGURE 2 ) with a black narrow band, adjacent to lateral margin, extending from posterior margin of pronotum to scutellar suture; scutellum with a pair of paramedial oval black maculae. Pronotum ( Fig. 2A View FIGURE 2 ) with posterior margin roundly excavated. Forewing ( Fig. 2D View FIGURE 2 , see arrow) with M vein partially fused to crossvein m-cu3. Male pygofer ( Fig. 2E, F View FIGURE 2 ), subrectangular; without dorsal processes; ventral margin with a small dentiform apical process; posterior margin truncated. Subgenital plates, in ventral view ( Fig. 2G View FIGURE 2 ) subtriangular, wider at base and narrowing toward apex; lateral margins with elongated microsetae. Aedeagus, in lateral view ( Fig. 2E, K, L View FIGURE 2 ), with shaft tubular, curved anterad, slightly tapering towards the apex. Female sternite VII ( Fig. 3A, C View FIGURE 3 ) subpentagonal, lateral margins with small acute projection in the median third; posterior margin rounded, slightly excavated medially.

Measurements. Males: total 5.9–6.3 (n = 21); females, 7.0– 7.5 mm (n = 25).

Coloration. Yellow to orange ( Fig. 1D–G View FIGURE 1 ). Crown and pronotum ( Fig. 2A View FIGURE 2 ) without maculae. Mesonotum ( Fig. 2A View FIGURE 2 ) with a black narrow band, adjacent to lateral margin, extending from posterior margin of pronotum to scutellar suture; scutellum with a pair of paramedial oval black macules. Forewing ( Figs 1D, F View FIGURE 1 , 2D View FIGURE 2 ) yellow with apical portion fuscous; a black or dark-brown band, partially outlining areas in red or orange, extending adjacently along almost the entire margin of clavus, directed towards the brachial cell after the anal veins, forming a large X-shaped macula when the wings in rest; central and inner anteapical cells and second and third apical cells often with a one dark macula. Legs ( Fig. 2E, G View FIGURE 2 ) yellow. Abdomen ( Fig. 3A, B View FIGURE 3 ) yellow except dorsal portion orange medially.

Description. Head, in dorsal view ( Fig. 2A View FIGURE 2 ), moderately produced anteriorly, median length of crown approximately three-quarters of interocular width; transocular width about six-sevenths of humeral width of pronotum; crown subrectangular; coronal maculae distinct. Head, in frontal view ( Fig. 2B View FIGURE 2 ), with face slightly wider than high; frons approximately 1.4 times longer than wide; maxillary plate produced ventrally, not surpassing the clypeus apex; clypeus approximately 1.7 times longer than maximum width, lateral margins parallel, apex rounded. Head, in lateral view ( Fig. 2C View FIGURE 2 ), with crown-face transition approximately rounded; frons convex. Forewing ( Fig. 2D View FIGURE 2 ) semi-hyaline, approximately 3.5 times longer than maximum width; M vein partially fused to crossvein m-cu3; second and third apical cells approximately rectangular, slightly expanded apically, fourth apical cell rhomboid; alar appendix narrow; apex rounded. Profemur with AD, AM, and PD rows reduced and poorly defined, with exception of apical setae AD 1, AM 1, and PD 1, respectively; AV and PV rows absent; IC row formed by slightly arched comb of fine setae, beginning at midlength and extending to apex. Protibia, in cross-section, semi-circular; AV row formed by approximately 15–16 setae, the 5–6 at basal third nearly half the length of the 10 distal ones, which are slightly longer and thicker towards apex; AD and PD formed by a single apical seta (AD 1 and PD 1); PV row with a single subapical seta.

Female terminalia. Sternite VII ( Fig. 3A, C View FIGURE 3 ) subpentagonal, 1.1 times wider than long; lateral margins straight and parallel, convergent in the apical third, with small acute projection in the median third; posterior margin rounded, slightly excavated medially. ʻInternalʼ sternite VIII membranous. Pygofer ( Fig. 3B, D View FIGURE 3 ) elongate, 1.7 times as long as maximum height; dorsal margin straight; ventral margin broadly rounded; macrosetae distributed near apex and ventral margin; apex truncated. Ovipositor ( Fig. 3B View FIGURE 3 ) slightly surpassing apex of pygofer, curved dorsally. First valvifer ( Fig. 3E View FIGURE 3 ) subtriangular, higher than long; anterior and dorsal margins straight, posterior margin oblique; angles rounded. First valvula of ovipositor ( Fig. 3E, F View FIGURE 3 ) elongated, height approximately constant throughout the length; dorsal sculptured area submarginal, present throughout apical half, expanded to the ventral region only in the apical portion, sculptured area striated; apex acute. Second valvifer ( Fig. 3I View FIGURE 3 ) higher than long. Second valvula of ovipositor ( Fig. 3G, H View FIGURE 3 ) elongated, fused to each on median portion; dorsal margin translucent, without ducts from base to near start point of teeth; apical portion slightly expanded, dorsal margin with several irregular small teeth and with one slightly larger rounded tooth, ducts ramified, root-shaped, ventral margin with few small teeth near apex. Gonoplac ( Fig. 3I, J View FIGURE 3 ) expanded on apical half; external surface along ventral margin and apex with dentiform cuticular projections and few short and robust setae; apex rounded.

Remarks. Salvina undata comb. nov. is easily recognizable from the other species of the genus due to the absence of maculae on the crown and pronotum ( Fig. 1D, F View FIGURE 1 ). While, S. distinctissima comb. nov. has a red median apical macula on the crown and a red macula on the pronotum, behind each eye ( Fig. 1A View FIGURE 1 ) and S. dorsisignata has three dark brown maculae in the pronotum, one median and one on each side ( Fig. 1B View FIGURE 1 ). Salvina undata comb. nov. is frequently found feeding on trees of Cinnamomum amoenum (Nees & Mart.) Kosterm ( Lauraceae ) in the locality where the specimens from Paraná, São José dos Pinhais (25°36’18”S, 49°11’37”W) were collected ( Domahovski 2021: fig. 46). Nymphs in different growth stages are also found with some frequency. The adults are found throughout the year, but always with low abundance.
