(Figs 1–3)
Diagnosis. Mesonotum (Fig. 2A) 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) with posterior margin roundly excavated. Forewing (Fig. 2D, see arrow) with M vein partially fused to crossvein m-cu3. Male pygofer (Fig. 2E, F), subrectangular; without dorsal processes; ventral margin with a small dentiform apical process; posterior margin truncated. Subgenital plates, in ventral view (Fig. 2G) subtriangular, wider at base and narrowing toward apex; lateral margins with elongated microsetae. Aedeagus, in lateral view (Fig. 2E, K, L), with shaft tubular, curved anterad, slightly tapering towards the apex. Female sternite VII (Fig. 3A, C) 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). Crown and pronotum (Fig. 2A) without maculae. Mesonotum (Fig. 2A) 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, 2D) 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) yellow. Abdomen (Fig. 3A, B) yellow except dorsal portion orange medially.
Description. Head, in dorsal view (Fig. 2A), 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), 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), with crown-face transition approximately rounded; frons convex. Forewing (Fig. 2D) 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. Metafemur with setal formula 2:2:1, with inner seta of second pair reduced in size. Metatibial AD row with 2–5 small intercalary setae between macrosetae; PD, AD, and PV rows with 15–16, 9–11, and 38–42 macrosetae, respectively; AV row with approximately 7–9 macrosetae distributed only in the middle third of tibia. Metatarsomere I longer than combined length of two distal tarsomeres; plantar surface with two rows of setae, external row with longer and robust setae than inner row; pecten with 4–5 platellae. Metatarsomere II pecten with 3 platellae.
Male terminalia. Pygofer, in lateral view (Fig. 2E, F), subrectangular, length approximately twice the height; dorsal and ventral margins approximately straight; ventral margin with a small dentiform apical process; posterior margin truncated; apex rounded. Anal tube (Fig. 2E) cylindrical; tergite X four times longer than wide. Subgenital plates, in lateral view (Fig. 2E, H) slightly surpassing the pygofer apex, narrow at base and apex, widened on median third; apex rounded; in ventral view (Fig. 2G) subtriangular, wider at base and narrowing toward apex; lateral margins with elongated microsetae; apex of each plate rounded. Connective (Fig. 2I) slightly shorter than style. Style (Fig. 2E, I, J) with some elongated setae on apical third of ventral margin; apex slightly curved ventrally. Aedeagus, in lateral view (Fig. 2E, K, L), with shaft tubular, curved anterad, slightly tapering towards the apex, apex subacute; gonopore apical.
Female terminalia. Sternite VII (Fig. 3A, C) 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) 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) slightly surpassing apex of pygofer, curved dorsally. First valvifer (Fig. 3E) subtriangular, higher than long; anterior and dorsal margins straight, posterior margin oblique; angles rounded. First valvula of ovipositor (Fig. 3E, F) 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) higher than long. Second valvula of ovipositor (Fig. 3G, H) 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) 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). 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) and S. dorsisignata has three dark brown maculae in the pronotum, one median and one on each side (Fig. 1B). 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.
