Cylapocoris fulvus Wolski sp. nov.

( Figures 4 , 16 , 34 , 45–49 , 50 , Table 1)

Diagnosis. Recognized by the pronotum with relatively broad, yellowish stripe along posterior margin ( Fig. 4 ), the dirty yellowish scutellum ( Fig. 4 ); endosoma with distinctly developed ML and thin and curved LS that is broadened at the basal one third and sharpened apically ( Fig. 45 ).

C. fulvus is most similar to C. simplex in sharing a similar body length and coloration of the corium ( Figs. 10 ). Together with C. barensis , C. marmoreus , C. simplex , and C. sulinus it shares an endosoma with the distinctly developed MS and similar shape of the DSS ( Figs. 56 , 80, 85 ; Carvalho 1982: Fig. 5 ). C. fulvus can, however, be easily distinguished by the coloration of the pronotum and scutellum ( Fig. 4 ) and the shape of the endosoma ( Fig. 45 ).

Description. Male. COLORATION ( Figs. 4 , 16 ). Mostly blackish brown, with large, dirty yellowish and yellowish areas. Head. Almost entirely blackish, except for dirty yellowish apical two thirds of clypeus and mandibular plate; antenna yellowish; extreme apex of segment I and base of segment II with narrow, fuscous annulation; labium with basal half yellowish and apical half dirty yellowish fuscous. Thorax. Pronotum. Blackish, with broad, yellowish stripe posteriorly, occupying almost one third of pronotum. Mesoscutum and scutellum. Dirty yellowish. Thoracic pleura. Blackish, except for yellowish ventral margin of proepimeron; scent gland efferent system dirty yellowish. Hemelytron. Mostly brown, somewhat darker basally; apex of endocorium and inner margin of cuneus with yellowish tinge; membrane fuscous; outer portions of veins of each cells dirty yellowish. Legs. Dirty yellowish. Abdomen. Dirty yellowish brown. STRUCTURE, TEXTURE, AND VESTITURE ( Figs. 1 , 16 , 34 ). Head. Shiny, covered with dense, semirecumbent setae; antenna thin; segment II cylindrical, covered with fine, semirecumbent setae; apex of labium reaching slightly beyond metacoxae. Pronotum. Covered with moderately deep punctation. Mesoscutum and scutellum. Scutellum moderately convex. Hemelytron. Rows of punctures along R+M vein, medial fracture, and vein on clavus indistinct, reaching beyond half of hemelytron; membrane with several obvious setae near outer margin.

Male genitalia. Aedeagus ( Fig. 45 ). Endosoma distinctly elongate; DSS strongly shortened and widened; ML distinctly developed, occupying most of endosoma; LS broadened at the basal one third and sharpened apically. Right paramere ( Figs. 46–47 ). Apical process: lateral view: slightly curved, sharpened at extreme apex; dorsal view: relatively sharpened apically; medial process moderately developed, relatively sharpened; left lateral margin almost straight. Left paramere ( Figs. 48–49 ). Paramere body: moderately broadened; apical process: lateral view: slightly curved; dorsal view: dorsal margin weakly sinuate; subapical incision distinct.

Antenna. Length of segment I 0.38–0.45 (0.45), II 0.9–0.93 (0.9), III 0.55–0.55 (0.5), IV 0.63. Labium. Length of segment I 0.53, II 0.55, III 0.5, IV 0.35. Pronotum. Length 0.61–0.62 (0.61), width of anterior margin 0.58–0.63 (0.58), length of lateral margin 0.53, width of posterior margin 1.25.

Female. Unknown.

Etymology. The specific name is taken from the Latin “ fulvus ” meaning tawny yellow and refers to the coloration of the posterior lobe of pronotum and scutellum.

Biology. Unknown.

Distribution. Ecuador (Orellana Province) ( Fig. 50 ).
