Diagnosis

This species can be diagnosed by the shape of the dorsal expansions of the hypandrium, especially by the two apical processes. Also, the shape of the posterolateral angles of pygophore (flat and quadrangular) is unique. The female genitalia is also diagnostic with the presence of a carina on the surface of gonocoxites 8, and the strongly convex gonocoxites 9.

Description

Dry preserved specimens pale yellow to green, probably green in life, punctures concolorous. General body shape oval ( Fig. 10B View Fig ), medium size. Head triangular. Juga slightly juxtaposed at apex, rounded. 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 produced in small pyramidal spines. Apex of scutellum obtuse; 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 slightly produced; at least distal half of tibiae dorsally sulcated. Abdominal venter slightly convex; anterior margins of spiracles surrounded by yellow callus.

Male genitalia ( Fig. 15A,B View Fig ). Pygophore quadrangular ( Fig. 15A,B View Fig ), nearly as long as wide. Median region of dorsal rim ( Fig. 15A View Fig , dr) sinuous; lateral third of dorsal rim folded toward genital chamber; marginal processes of dorsal rim triangular ( Fig. 15A View Fig , mp), closely related to the parameres ( Fig. 15A View Fig , pa). Posterolateral angles flat, quadrangular ( Fig. 15A View Fig , pan). Median excavation of ventral rim V-shaped in ventral view ( Fig. 15B View Fig , vr). Hypandrium surpassing ventral rim ( Fig. 15A,B View Fig , hy); with 1+1 broad laminar-like expansions flanking segment X, dorsally bearing two narrow, apical rounded processes: one laterad ( Fig. 15A View Fig , lpr) and other backward directed ( Fig. 15A View Fig , ppr); ventral wall shorter than dorsal expansions, in a channel-like structure ( Fig. 15B View Fig , vw). Parameres spatulated, apical and medial spines present. Segment Xogival ( Fig. 15A, X View Fig ), with 1 +1 tubercle laterad to the constriction line. Male not dissected.

Female genitalia ( Fig. 16A,B View Fig ). Gonocoxites 8 quadrangular ( Fig. 16A View Fig , gc8); posterior margin slightly convex; apical half of sutural margins divergent; transversal carina arising from the sutural angles. Laterotergites 8 and 9 equal in length ( Fig. 16A View Fig , la8, la9); posterior angle of laterotergites 8 acute; posterior angle of laterotergites 9 obtuse. Gonocoxites 9 trapezoidal, strongly convex ( Fig. 16A View Fig , gc9). Gonapophyses 9 with 1+1 triangular sclerotized areas ( Fig. 16B View Fig , g9). Anterior thickening of vaginal intima in a ring-like structure ( Fig. 16B View Fig , tvi). Base of internal rod of ductus receptaculi bulbousshaped. Capsula seminalis subcylindrical ( Fig. 16B View Fig , cs), with three processes variable in length ( Fig. 16B View Fig , pcs): two reaching the free margin of posterior annular flange ( Fig. 16B View Fig , paf) and another shorter.

Distribution

Costa Rica: Costa Rica, Guanacaste.

Phylogenetic considerations

Chloropepla costaricensis   forms a monophyletic group with C. aurea   and C. pirani   , by sharing humeral angles produced in spine (10) and femur apical process moderately produced (80).

Etymology

The species was named after the country where the specimens were collected.
