Cylapocoris castaneus (Carvalho) comb. nov.

( Figures 1 , 13 , 23–27 , 50 , Table 1)

Adcylapocoris castaneus Carvalho 1989b: 80 , Figs. 1–4 (n. sp.); Carvalho & Froeschner 1994: 485 (list); Schuh 1995: 19 (catalog); Gorczyca 2006b: 25 (catalog).

Diagnosis. Recognized by the following set of features: antennal segment II stout, with narrow, yellowish annulation apically ( Figs. 1 , 13 ); pronotum impunctate, rugose ( Fig. 1 ); vestiture on membrane distinctly developed, occupying entire surface outside cells; endosoma with mesial lobe (ML) distinctly developed, occupying most of endosoma ( Fig. 23 ); right paramere distinctly curved, with apical process, in dorsal view, with sinistrolateral margin distinctly convex medially ( Figs. 24–25 ).

Most similar to C. laevigatus , C. marmoreus , C. simplex , and C. sulinus in sharing endosoma devoid of sclerites AS, LS, and MS with distinctly developed mesial lobe (MS), occupying most of endosoma ( Figs. 51, 56 , 80, 85 ). Together with C. costaricaensis it shares densely distributed vestiture on membrane ( Fig. 90 ). With C. laevigatus it shares impunctate, rugose pronotum ( Figs. 1 , 38 ). C. castaneus can, however, be distinguished by the apical process of the right paramere, in dorsal view, with sinistrolateral margin distinctly convex medially ( Fig. 25 ).

Redescription. Male. COLORATION ( Figs. 1 , 13 ). Dorsum almost entirely dark castaneous. Head. Dark castaneous except for dark yellowish posterior half of buccula and gula; antennal segment I dirty yellowish dark castaneous; segment II blackish with narrow, contrastingly pale, yellowish annulation apically; segments III and IV blackish, with brownish basal one third of segment III; labium dirty yellowish brown. Thorax. Pronotum. Dark castaneous with somewhat darker, dark brown pronotal calli. Thoracic pleura. Castaneous with dirty yellowish and reddish areas. Hemelytron. Membrane fuscous. Legs. Procoxa dirty yellowish with reddish tinges; meso- and metacoxae dark brown with dirty yellowish areas; metafemur dirty yellowish tinged with red; metatibia and metatarsus dirty yellowish; remaining leg segments lacking in the examined specimen. Abdomen. Dark brown with indistinct dirty yellowish areas. STRUCTURE, TEXTURE, AND VESTITURE ( Figs. 1 , 13 ). Head. Covered with setae similar to those present on dorsum but more irregularly distributed; antennal segment II relatively stout, somewhat thickened medially, entirely covered with semirecumbent, relatively short, thick, black setae. Thorax. Pronotum. Impunctate, slightly rugose. Mesoscutum and scutellum. Scutellum moderately convex. Hemelytron. Membrane covered with relatively dense setae on entire area outside cells. Abdomen. Covered with relatively dense, semirecumbent setae.

Male genitalia. Aedeagus ( Fig. 23 ). Endosoma membranous with distinctly developed, ellipsoidal mesial lobe (ML); DSS relatively long, longer than its basal width, cylindrical. Right paramere ( Figs. 24–25 ). Apical process: lateral view: curved medially, sharply pointed apically; dorsal view: sinistrolateral margin distinctly curved medially; extreme apex and medial process obtuse; paramere body: distinctly thickened, curved apically; dorsal surface with bundle of erect, long setae. Left paramere ( Figs. 26–27 ). Paramere body: somewhat thickened, with bundle of erect, long setae; apical process: lateral view: straight, weakly thickened near apex, sharply pointed apically; dorsal view: dorsal margin slightly sinuate; extreme apex relatively elongate; subapical incision relatively deep.
