description: <i>Triunfus carvalhoi</i> sp.n. Figs. 14 A– F, 16 B, D – F, 17, 18 Fv, L, 20 B, D, H, J, L <b>Diagnosis.</b> Valvifers 8 shorter than laterotergites 9. Valvifers 9 swollen, posterior margins convex. Lateral scle- rotized areas of valvulae 9 well-defined, sclerotized. Diameter of proximal ductus receptaculi equal to diameter of median wall of vesicular area. <i>Capsula seminalis</i> equal in length to <i>pars intermedialis</i>, with a process. <b> Description. <i>Measurements</i></b> : Table 4. <i>Colouration</i>: Gen- eral colour dark brown dorsally and ventrally; densely punctate. Head and clypeus with ferruginous callosities; antennomeres uniformly brownish; brown blotches on antenniferous tubercles and maxillary plates. Sublateral margins of pronotum and lateral margins of coria fer- ruginous. Pro-, meso-, metasternum and evaporatorium dark brown. Coxae, trochanters, and apical half of each femur ferruginous, tibiae and tarsi brown. Connexivum ferruginous. Abdominal sternites brown, sublateral band from prosternum to abdominal sternite 7 ferruginous. Spiracles dark brown. Trichobothria brown. <i>Head</i> (Figs. 14A, D–E, 20D, F, H): Anteocular processes absent. Proportions of antennomeres: 1&gt; 2 &lt;3&gt; 4 &lt;5 (Figs. 14D, 18 Fv, 20H). <i>Thorax</i>: Pronotum with anterior an- gles not produced; anterolateral margins straight, smooth; humeral angles not produced (Figs. 14A, 20J). Gyrifica- tion of evaporatorium with high wrinkles; anterolateral margin of each evaporatorium rounded; outer margin of each metapleural evaporatorium concave (Fig. 18L). Membrane with veins linear, some bifurcated basally. Hemelytra not surpassing apex of abdomen. <i>Abdomen</i>: Posterolateral angles of each connexivum not produced (Figs. 14A, 20L). <i>Female terminalia</i> (Figs. 14F, 16B, D): Valvifers 8 shorter than laterotergites 9, partially cover- ing valvifers 9. Laterotergites 8 triangular, straight api- cally. Valvifers 9 swollen, leveled, relative to the position of segment X; posterior margins convex, lateral margins with 1 + 1 processes. Laterotergites 9 triangular, obtusely rounded apically (Fig. 16B). <i>Female genitalia</i>: Ectoder- mal ductus (Fig. 16 E–F): Diameter of proximal ductus receptaculi equal to diameter of median wall of vesicular area. Annular flanges divergent. <i>Pars intermedialis</i> recti- linear. <i>Capsula seminalis</i> globose, equal in length to <i>pars intermedialis</i>, with a process. <b>Male.</b> Unknown. <b>Etymology</b>. This species is named in honour to Dr. Ger- vásio Silva Carvalho, specialist dedicated to phylogeny and biogeography of Neotropical Auchenorrhyncha. <b>Type material</b>: Holotype &amp;female;, ‘ BRAZIL, Rio Grande do Sul, Tri- unfo | Projeto Sitel/Corsan | 7 – 11.i.2002 | Equipe do Projeto leg.’ | ‘ 17302-1 MCTP’ (MCTP). – Paratype: &amp;female;, ‘ BRAZIL, Rio Grande do Sul, Capão do Leão’ (UFRG) &lt;illustrated specimen&gt;. <b>Distribution.</b> Brazil: Rio Grande do Sul (Fig. 17).
