- Triunfusincarnatus sp.n. Figs. 15 A– F, 16G, 17 Diagnosis. Valvifers 8 equal in length to laterotergites 9. Valvifers 9 flat with posterior margins straight. Lateral sclerotized areas of valvulae 9 scarcely defined or scle- rotized. Diameter of proximal ductus receptaculi greater than diameter of median wall of vesicular area. Capsula seminalis without processes, shorter than pars intermedialis. Description. Measurements : Table 4. Colouration. Gen- eral colour orange-castaneous dorsally, dark brown ven- trally; densely punctate. Head and clypeus with oranges callosities; ocelli orange; antennomeres brownish, ex- cept antennomere 5 orange-castaneous; yellow blotches on antenniferous tubercles and maxillary plates; labium orange-brown. Outline of anterolateral margins of prono- tum and a medial longitudinal line on scutellum orangecastaneous. Pro-, meso-, metasternum and evaporatorium dark brown; ostiolar peritremes orange. Legs dark brown, except coxae, trochanters, and apical third of each femora orange. Connexivum yellowish-orange. Abdominal ster- nites dark castaneous, sublateral band from prosternum to abdominal sternite 7 yellowish-orange. Spiracles dark castaneous. Trichobothria castaneous. Head (Fig. 15A, D): Anteocular processes absent. Proportions of antenno- meres: 1> 2 <3> 4 <5 (Fig. 15E). Thorax: Pronotum with anterior angles not produced; anterolateral margins straight, smooth; humeral angles not produced (Fig. 15A, D). Gyrification of evaporatorium with high wrinkles; an- terolateral margin of each evaporatorium rounded; outer margin of each metapleural evaporatorium concave (Fig. 15F). Membrane with veins linear, some bifurcate basally. Hemelytra not surpassing apex of abdomen. Female terminalia: Valvifers 8 subequal in length to laterotergites 9, partially covering valvifers 9. Laterotergites 8 triangu- lar, posterior margins straight. Valvifers 9 flat, leveled, relative to the position of segment X; posterior margins straight, lateral margins entire. Laterotergites 9 triangu- lar, posterior margins obtusely rounded. Female genitalia: Valvulae 9 with 1 + 1 lateral areas scarcely defined or sclerotized, placed along with ring sclerite. Ectodermal ductus (Fig. 16G): diameter of the proximal ductus recep- taculi greater than diameter of median wall of vesicular area. Annular flanges divergent. Pars intermedialis rec- tilinear. Capsula seminalis globose, without processes, shorter than pars intermedialis. Male. Unknown. Etymology. Incarnatus, in Latin, orange, referring to the orange body colour; adjective. Type material: Holotype ♀, ‘ BRAZIL, Rio Grande do Sul, [prob- ably São Lourenço do Sul] | [?]. iv.1995 Loescher L. leg.’ (MECB) <Illustrated specimen, abdomen and terminalia prepared>. Distribution.
