Chloropepla rideri sp.n. ( Figs 10A View Fig , 11 View Fig , 12 View Fig )
Diagnosis
Chloropepla rideri sp.n. differs from the remaining species of Chloropepla 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.

Holotype. Brazil, Bahia: ♂, labeled BRAZIL, Bahia, Encruzilhada , 960 m, nov. 1972, M. Alvarenga col.’ ( AMNH) . Paratypes. Brazil, Bahia: 6♀ and 4♂ labeled as the holotype ( AMNH; 1♀ and 1♂ UFRG). Minas Gerais: 2♀ and ♂ ‘ BRAZIL, Minas Gerais (Minas Geraes)., Pedra Azul , 900m, November, 1972, M. Alvarenga col.’ ( AMNH) .
Description
Dry preserved specimens pale yellow, probably green in life, punctures concolorous. General body shape oval ( Fig. 10A View Fig ), small sized. Head triangular. Juga juxtaposed at the apex. Proportionof antennalsegments: I <II <III ≤ IV ≤ V. Bucculaevanescentat base. First rostral segment slightly surpassing buccula. Proportion of rostral segments: I <II> 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 View Fig ). Pygophore rectangular ( Fig. 11A,B View Fig ), approximately 0.2 times longer than wide. Median region of dorsal rim ( Fig. 11A View Fig , dr) bilobate; lateral third of dorsal rim slightly folded toward the genital chamber; marginal processes of dorsal rim triangular ( Fig. 11A View Fig , mp), closely related to the parameres ( Fig. 11A View Fig , pa). Median excavation of ventral rim U-shaped ( Fig. 11A View Fig , vr). Hypandrium ( Fig. 11A,B View Fig , hy) surpassing ventral rim; with 1+1 broad laminar expansions flanking the segment Xdorsally, bearing an elongated process ( Fig. 11A View Fig , 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 View Fig , vwhy). Paramere club-shaped ( Fig. 11C View Fig ), apical and medial spines present. Segment Xogival ( Fig. 11A, X View Fig ) with 1 +1 lateral carina at base. Phallus ( Fig. 11D–F View Fig ). Articulatory apparatus ( Fig. 11D–F View Fig , aa) about half the length of phallotheca ( Fig. 11D–F View Fig , ph). Phallotheca cylindrical, with two pairs of processes: 1 +1 elliptical at base of the posterior wall (= processus phallothecae 1) ( Fig. 11D View Fig , prphI); 1 +1 ear-like at postero-lateral angles of the anterior wall (= processus phallothecae 2) ( Fig. 11F View Fig , prphII). Conjunctiva reduced ( Fig. 11D View Fig , cj), completely obscured by phallotheca. Vesica short ( Fig. 11D,E View Fig , ve), cylindrical and much wider than the final portion of the ductus ejaculatory; basal portion surrounded by a collar-like process ( Fig. 11D View Fig , vp).
Female genitalia ( Fig. 12 A,B View Fig ). Gonocoxites 8 rectangular ( Fig. 12A View Fig , gc8), posterior margin convex, apical third of sutural margins divergent. Apical angle of laterotergites 8 acute ( Fig. 12A View Fig , la8); obtuse in laterotergites 9 ( Fig. 12A View Fig , la9). Laterotergites 9 slightly shorter than laterotergites 8. Gonocoxites 9 trapezoidal ( Fig. 12A View Fig , gc9), posterior margin straight. Gonapophyses 9 with 1+1 triangular sclerotized regions ( Fig. 12B View Fig , g9). Anterior thickening of vaginal intima tube shaped ( Fig. 12B View Fig , tvi), nearly as long as the gonapophyses 9. Base of internal rod of ductus receptaculi bulbousshaped. Capsula seminalis subcylindrical ( Fig. 12B View Fig , cs), with three processes variable in length ( Fig. 12B View Fig , pcs): two surpassing the posterior annular flange ( Fig. 12B View Fig , paf) in almost half of their length and the third nearly reaching the anterior annular flange ( Fig. 12B View Fig , aaf).
Distribution
Brazil: Bahia and Minas Gerais.
