description: <b> <i>Chloropepla rideri</i> sp.n.</b> (Figs 10A, 11, 12) <i>Diagnosis</i> <i>Chloropepla rideri</i> sp.n. differs from the remaining species of <i>Chloropepla</i> by the unique shape of the hypandrium, with the broad dorsal expansions bearing elongated processes. Also, in the female internal genitalia the well developed thickening of vaginal intima and the long processes of the capsula seminalis are distinct in this species. <i>Specimens examined</i> <i>Holotype</i>. Brazil, Bahia: &amp;male;, labeled BRAZIL, Bahia, Encruzilhada, 960 m, nov. 1972, M. Alvarenga col.’ (AMNH). <i>Paratypes</i>. Brazil, Bahia: 6&amp;female; and 4&amp;male; labeled as the holotype (AMNH; 1&amp;female; and 1&amp;male; UFRG). Minas Gerais: 2&amp;female; and &amp;male; ‘ BRAZIL, Minas Gerais (Minas Geraes)., Pedra Azul, 900m, November, 1972, M. Alvarenga col.’ (AMNH). <i>Description</i> Dry preserved specimens pale yellow, probably green in life, punctures concolorous. General body shape oval (Fig. 10A), small sized. Head triangular. Juga juxtaposed at the apex. Proportionof antennalsegments: I &lt;II &lt;III ≤ IV ≤ V. Bucculaevanescentat base. First rostral segment slightly surpassing buccula. Proportion of rostral segments: I &lt;II&gt; III ≥ IV. Pronotum trapezoidal, anteriorhalf slightly declivous; puncturesuniformly distributed, cicatrices immaculate. Basal two thirds of anterolateral margins crenulated. Anterior margin concave, behind the eyes truncated. Humeral angles acute, but not produced into spines. Scutellum with punctures uniformly distributed. Hemelytra wide, almost obscuring connexiva completely. Corium uniformly punctured; apical angle of corium obtuse, reaching base of connexivum VII; yellow callus at apex of radial vein present. Peritreme attaining nearly ¾ of metapleura, ostiole elliptical. Distal spine of dorsal surface of femur distinct; at least distal half of tibiae dorsally sulcated. Abdominal venter slightly convex; anterior margins of spiracles surrounded by yellow callus. Male genitalia (Fig. 11A–F). Pygophore rectangular (Fig. 11A,B), approximately 0.2 times longer than wide. Median region of dorsal rim (Fig. 11A, dr) bilobate; lateral third of dorsal rim slightly folded toward the genital chamber; marginal processes of dorsal rim triangular (Fig. 11A, mp), closely related to the parameres (Fig. 11A, pa). Median excavation of ventral rim U-shaped (Fig. 11A, vr). Hypandrium (Fig. 11A,B, hy) surpassing ventral rim; with 1+1 broad laminar expansions flanking the segment Xdorsally, bearing an elongated process (Fig. 11A, epr), extending from the base to almost the apex of the expansion; ventral wall of hypandrium shorter than dorsal wall, flat, without processes (Fig. 11B, vwhy). Paramere club-shaped (Fig. 11C), apical and medial spines present. Segment Xogival (Fig. 11A, X) with 1 +1 lateral carina at base. Phallus (Fig. 11D–F). Articulatory apparatus (Fig. 11D–F, aa) about half the length of phallotheca (Fig. 11D–F, ph). Phallotheca cylindrical, with two pairs of processes: 1 +1 elliptical at base of the posterior wall (= processus phallothecae 1) (Fig. 11D, prphI); 1 +1 ear-like at postero-lateral angles of the anterior wall (= processus phallothecae 2) (Fig. 11F, prphII). Conjunctiva reduced (Fig. 11D, cj), completely obscured by phallotheca. Vesica short (Fig. 11D,E, ve), cylindrical and much wider than the final portion of the ductus ejaculatory; basal portion surrounded by a collar-like process (Fig. 11D, vp). Female genitalia (Fig. 12 A,B). Gonocoxites 8 rectangular (Fig. 12A, gc8), posterior margin convex, apical third of sutural margins divergent. Apical angle of laterotergites 8 acute (Fig. 12A, la8); obtuse in laterotergites 9 (Fig. 12A, la9). Laterotergites 9 slightly shorter than laterotergites 8. Gonocoxites 9 trapezoidal (Fig. 12A, gc9), posterior margin straight. Gonapophyses 9 with 1+1 triangular sclerotized regions (Fig. 12B, g9). Anterior thickening of vaginal intima tube shaped (Fig. 12B, tvi), nearly as long as the gonapophyses 9. Base of internal rod of ductus receptaculi bulbousshaped. Capsula seminalis subcylindrical (Fig. 12B, cs), with three processes variable in length (Fig. 12B, pcs): two surpassing the posterior annular flange (Fig. 12B, paf) in almost half of their length and the third nearly reaching the anterior annular flange (Fig. 12B, aaf). <i>Distribution</i> Brazil: Bahia and Minas Gerais. <i>Etymology</i> The species was named in honor of Dr. David Rider for his great contribution to the knowledge of Pentatomoidea.
