Chloropepla caxiuanensis sp.n. ( Figs 10C View Fig , 17 View Fig , 18 View Fig )

Diagnosis

Chloropela caxiuanensis sp.n. may be distinguished by characteristics of the hypandrium: the shape of the dorsal expansions and the shape of the ventral projection. The reduced thickening of vaginal intima associated to the shape of capsula seminalis are also useful to differentiate the females of this species.

Specimens examined

Holotype. Brazil, Pará: ♂, labeled ‘ Flona Caxiuanã- Melgaço , Pará, Brasil, XI-2003 Fernandes, J.A.M. ’, ‘ Base da Estação Científica Ferreira Penna , coleta manual noturna sob luz branca’ ( MPEG) . Paratypes. Brazil, Pará: ♀ labeled as the holotype ( UFRG). Venezuela, Amazonas: 1♂ and 3♀ ‘ VENEZUELA, Exp. Territorio Amazonas, Mount Marahuaca , N. Slopes, Benitez Camp, May 1-25, 1950, J. Maldonado Caprilles col., Drake Colln.’ ( NMNH) .

Description

Dry preserved specimens pale yellow, probably green in life, punctures concolorous ( Fig. 10C View Fig ). Anterior margin of the pronotum with sparse dark punctures. Anterior margin of humeral angles with a dark line. Dark line in the apical half of lateral surface of antennal segment I, and along the lateral surface of antennal segment II. Apical third of antennal segment III dark, segment IV and Vwith at least the apical ¾ dark. Apex of tibia and tarsal segments Iand II bordered by black; base of tarsal segment III bordered by black. Posterolateral angles of connexiva with tiny dark acute process.

General body shape oval ( Fig. 10C View Fig ), medium size. Head triangular in shape. Juga surpassing clypeus, slightly juxtaposed at apex, obtuse. Lateral margins sinuate. Proportion of antennal segments: I <II <III <IV=V. Buccula evanescent at base of head; anterior angle with an acute process (denticle); first rostral segment slightly surpassing buccula. Rostrum reaching the third abdominal segment; proportion of rostral segments: I <II>III≥ IV. Pronotum trapezoidal, anterior half slightly declivous; cicatrices immaculate. Basal two thirds of anterolateral margins crenulated. Anterior margin concave, behind the eyes truncated. Humeral angles acute, but not produced into spines. Apex of scutellum obtuse; punctures uniformly distributed. Hemelytra wide, almost obscuring connexiva completely. Corium uniformly punctured; apical angle of corium obtuse, reaching half of connexivum VII; yellow callus at apex of radial vein present. Peritreme attaining nearly three-quarters of metapleura, ostiole elliptical. Distal spine of dorsal surface of femur inconspicuously produced; at least distal half of tibia dorsally sulcated. Abdominal venter slightly convex; anterior margins of spiracles surrounded by yellow callus.

Male genitalia ( Fig. 17 View Fig A–F). Pygophore quadrangular ( Fig. 17A,B View Fig ), almost as long as wide. Median region of dorsal rim ( Fig. 17A View Fig , dr) in an open and shallow “V”; lateral third of dorsal rim folded toward the genital chamber; marginal processes of dorsal rim digitiform ( Fig. 17A View Fig , mp), closely related to the parameres ( Fig. 17A View Fig , pa). Median excavation of ventral rim U-shaped in ventral view ( Fig. 17A View Fig , vr); infolding of ventral rim with 1+ 1 darkish process dorsally produced, on the sides of the excavation. Hypandrium surpassing ventral rim ( Fig. 17A,B View Fig , hy); with 1+1 broad laminar-like expansions flanking the segment X, dorsally bearing a laminar process near the apex ( Fig. 17A View Fig , dpr); ventral wall of hypandrium almost as long as dorsal wall, projected posteriorly in a gutter-like process and medially projected in 1+ 1 triangular flaps ( Fig. 17B View Fig , vpr). Paremere cylindrical at base and spatulated at apex ( Fig. 17C View Fig ), only apical spine present; lateral surface, near the apex, with granular texture. Apex of segment Xogival ( Fig. 17A, X View Fig ), with 1 +1 lateral tubercle at base. Phallus ( Fig. 17D–F View Fig ). Articulatory apparatus ( Fig. 17D–F View Fig , aa) about half the length of phallotheca ( Fig. 17D– F View Fig , ph). Phallotheca cylindrical, with two pairs of processes: 1+1 elongated at base of the posterior wall (= processus phallothecae 1) ( Fig. 17D View Fig , prph1) and 1 +1 ear-like at postero-lateral angles of anterior wall (=processus phallothecae 2) ( Fig. 17F View Fig , prph2). Conjunctiva reduced ( Fig. 17D View Fig , cj), completely obscured by phallotheca. Vesica short ( Fig. 17D View Fig , ve), bulbous; basal portion surrounded by a collar-like process ( Fig. 17D View Fig , vp).

Female genitalia ( Fig. 18A,B View Fig ). Gonocoxites 8 quadrangular ( Fig. 18A View Fig , gc8); posterior margin slightly convex; apical forth of sutural margins divergent. Laterotergites 8 and 9 equal in length ( Fig. 18A View Fig , la8, la9); both with apical angle triangular (nearly acute). Gonocoxites 9 trapezoidal ( Fig. 18A View Fig , gc9). Gonapophyses 9 with 1+ 1 triangular sclerotized regions ( Fig. 18B View Fig , g9). Anterior thickening of vaginal intima reduced, hood-shaped ( Fig. 18B View Fig , tvi). Base of internal rod of ductus receptaculi bulbous-shaped. Capsula seminalis subcylindrical ( Fig. 18B View Fig , cs), with three processes variable in length ( Fig. 18B View Fig , pcs): one reaching the free margin of posterior annular flange ( Fig. 18B View Fig , paf) and the other two shorter.
