Diagnosis. 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. Capsula seminalis equal in length to pars intermedialis, with a process.

Description. Measurements: Table 4. Colouration: 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. Head (Figs. 14A, D–E, 20D, F, H): Anteocular processes absent. Proportions of antennomeres: 1> 2 <3> 4 <5 (Figs. 14D, 18 Fv, 20H). Thorax: 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. Abdomen: Posterolateral angles of each connexivum not produced (Figs. 14A, 20L). Female terminalia (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). Female genitalia: Ectoder- mal ductus (Fig. 16 E–F): Diameter of proximal ductus receptaculi equal to diameter of median wall of vesicular area. Annular flanges divergent. Pars intermedialis recti- linear. Capsula seminalis globose, equal in length to pars intermedialis, with a process.
