Cylapocoris marmoreus Wolski  sp. nov.

( Figures 8View FIGURES 1 – 12, 19View FIGURES 13 – 22, 56–61View FIGURES 51 – 60View FIGURE 61, Table 1)

Diagnosis. Recognized by the small body length (3.7 mm), the dorsum with relatively large, yellowish patches ( Fig. 8View FIGURES 1 – 12), the antennal segment II with relatively broad, apical, yellowish annulation ( Fig. 19View FIGURES 13 – 22), the endosoma with the DSS strongly reduced, as long as its width ( Fig. 56View FIGURES 51 – 60), the other endosomal sclerites absent ( Fig. 56View FIGURES 51 – 60), and the ML strongly developed, occupying most of endosoma ( Fig. 56View FIGURES 51 – 60).

C. marmoreus  is most similar to C. barensis  , C. fulvus  , C. simplex  , and C. sulinus  in sharing the pale patch on apex of the corium ( Figs. 4, 10– 11View FIGURES 1 – 12) and an endosoma with the distinctly developed ML and distinctly reduced DSS ( Figs. 45View FIGURES 40 – 49, 80, 85View FIGURES 80 – 89; Carvalho 1982: Fig. 5View FIGURES 1 – 12). The present new species can, however, be distinguished by the pale patches on the dorsum ( Fig. 10View FIGURES 1 – 12) and the shape of the endosoma ( Fig. 56View FIGURES 51 – 60).

Description. Male. COLORATION ( Figs. 8View FIGURES 1 – 12, 19View FIGURES 13 – 22). Dark castaneous with relatively large, dirty yellowish patches. Head. Mostly dark brown; vertex with two distinct, yellowish patches laterally, each contiguous inner margin of eye and two pale patches on pronotal collar; frons with indistinct, dirty yellowish tinges; antennal segment I dark brownish with yellowish brown one fourth and annulation at extreme apex; segment II dark brown except for contrastingly pale, dirty yellow annulation at apical one third; segment III and IV blackish; labial segment I dark reddish with dark brown basal portion; remainder of labium fuscous. Thorax. Pronotum. Dark castaneous with large, brownish and dirty yellowish areas; pronotal collar with two very broad, dirty yellowish patches medially; anterior lobe with single yellowish brown patch between pronotal calli, contiguous with pronotal collar; remainder of pronotum with large, dirty yellowish and brownish patches occupying most of posterior lobe, posterior margin, and humeral angle. Mesoscutum and scutellum. Mesoscutum blackish with two yellowish, relatively large patches laterally; scutellum dark castaneus  , with yellowish patch basally. Thoracic pleura. Blackish; scent gland efferent system fuscous with dark red peritreme. Hemelytron. Mostly dark castaneous with numerous dirty yellowish patches on clavus, corium, and extreme apex of cuneus; membrane blackish, with outer portion of major cell vein yellowish. Legs. Blackish dark brown with dirty yellowish areas; procoxa blackish; meso- and metacoxa blackish basally, dirty yellowish apically; trochanters dirty yellowish, tinged with red; femora dark brownish with yellow patches; tibiae dark brownish, with three, indistinct, dirty yellowish annulations: one situated near base, second situated medially, and third situated apically; tarsus dirty yellowish brown. Abdomen. Blackish. STRUCTURE, TEXTURE, AND VESTITURE ( Figs. 8View FIGURES 1 – 12, 19View FIGURES 13 – 22). Head. Slightly rugose, covered with moderately dense, irregularly distributed setae; antennal segment I somewhat narrowed basally, remainder of segment I almost cylindrical; segment II relatively stout, thickened toward apex; labium thin, long, with apex reaching pygophore. Thorax. Pronotum. Pronotum with shallow punctation. Mesoscutum and scutellum. Scutellum convex.

Male genitalia. Aedeagus ( Fig. 56View FIGURES 51 – 60). Endosoma strongly membranous; DSS with very small length and width; other sclerites absent; ML nearly ellipsoidal, strongly developed, occupying most of endosoma. Right paramere ( Figs. 57–58View FIGURES 51 – 60). Paramere body: inner margin slightly sinuate; apical process: lateral view: moderately curved, rounded apically; dorsal view: left lateral margin distinctly sinuate, apex rounded, medial process distinctly developed, rounded. Left paramere ( Figs. 59–60View FIGURES 51 – 60). Apical process: lateral view: straight; dorsal view: relatively narrow, with subapical incision rather shallow, apex rounded.

Measurements. Holotype ♂: Body. Length 3.7, width 1.6. Head. Length 0.35, width 0.83, interocular distance 0.5. Antenna. Length of segment I 0.45, II 1.0, III 0.44, IV 0.68. Labium. Length of segment I 0.68, II –IV 1.63. Pronotum. Length 0.75, width of anterior margin 0.7, length of lateral margin 0.63, width of posterior margin 1.38.

Female. Unknown.

Etymology. The specific epithet is derived from the Latin “marmor” meaning marbled, and is used to denote the mottled coloration of the hemelytra.

Biology. Unknown

Distribution. Costa Rica (Cartago: Turrialba) ( Fig. 61View FIGURE 61).

Type material. Holotype ♂: COSTA RICA, Cart. Turrialba, CATIE, 26–29 Jun 1986, W. Hanson, G. Bohart (AMNH) ( Figs. 8View FIGURES 1 – 12, 19View FIGURES 13 – 22).
