description: Cylapocoris laevigatus Wolski sp. nov.
(Figures 6–7, 18, 35, 38, 50, 51–55, Table 1)
Diagnosis. Recognized by the following set of characters: dorsum dark castaneous (Figs. 6–7); posterior half of buccula and gula contrastingly yellow (Fig. 18); endosoma with medial lobe (ML) strongly enlarged (Fig. 51); DSS somewhat convex dextrolaterally (Fig. 51), right paramere with apical process in dorsal view ellipsoidal, with medial process moderately developed, rounded (Fig. 53); left paramere with apical process, in dorsal view, with dorsal and ventral margins weakly curved and shallow subapical incision (Fig. 55).
Most similar to C. castaneus in sharing an impunctate pronotum (Fig. 1). With C. castaneus, C. fulvus, C. marmoreus, C. simplex, and C. sulinus the present new species shares an endosoma with the strongly enlarged medial lobe (ML) (Figs. 23, 45, 56, 80, 85). It can, however, be easily distinguished by the contrastingly yellow posterior half of buccula and gula (Fig. 18) and the shape of the male genitalia (Figs. 51–55).
Description. Male. COLORATION (Figs. 6–7, 18). Mostly castaneous with blackish areas. Head. Mostly dark castaneous; vertex, frons, mandibular plates, basal half of clypeus, anterior half of buccula castaneous; vertex and frons with indistinct, narrow, brownish stripes laterally, each contiguous with inner margin of eye, originating from posterior margin of vertex and terminating on antennal insertion; apical half of clypeus and labrum dark red; maxillary plate dirty yellowish dark brown; posterior half of buccula and gula contrastingly yellow; antennal segment I mostly yellowish, with relatively broad, dark brown annulation somewhat beyond base and with narrow, dark red annulation at extreme apex; antennal segment II mostly black with dark brown basal one third and pale, yellowish or reddish annulation at extreme apex; segments III and IV mostly fuscous; basal half of segment III yellow; labial segment I dark reddish brown at basal one third, remainder of segment I yellow, tinged with red; segments II–IV yellow, slightly tinged with fuscous. Thorax. Pronotum. Castaneous except for somewhat paler, brownish humeral angles. Mesoscutum and scutellum. Entirely dark castaneous. Thoracic pleura. Proepisternum with ventral half yellow and dorsal half dark brown; proepimeron mostly dark brown with narrow, pale, dirty yellowish stripe along lateral margin of pronotum and with yellowish patch antero-ventrally; remaining pleura dark castaneous; scent gland efferent system reddish fuscous. Hemelytron. Castaneous with small, pale, dirty yellowish patch on clavus apically and inner angle of endocorium. Legs. Procoxa yellowish, slightly tinged with red or fuscous; meso- and metacoxae dark brown with relatively small, reddish yellow patch at extreme apex; remaining segments dirty yellowish, sometimes tinged with red. Abdomen. Dirty yellowish brown with large, reddish tinges. STRUCTURE, TEXTURE, AND VESTITURE (Figs. 6–7, 18, 35, 38). Head. Covered with long, dense, erect setae; antennal segment I covered with moderately dense, recumbent setae, basal one third slightly narrowed, remainder of segment cylindrical; segment II stout, thickened toward apex, slightly bicompressed at apical two thirds, segment II with basal one third covered with dark, rather dense, thick, erect and semierect setae becoming denser on remainder of segment, extreme apex (where segment is yellow) with shorter and adpressed setae; labium reaching middle of abdomen. Thorax. Pronotum. Impunctate, rugose. Mesoscutum and scutellum. Scutellum moderately convex. Hemelytron. Membrane with distinct, moderately dense vestiture near outer margin.
Male genitalia. Aedeagus (Fig. 51). Endosoma strongly membranous; DSS moderately curved, relatively long, with right margin convex medially; ML distinctly enlarged, occupying almost entire basal half of the endosoma; apical half of endosoma composed of three membranous lobes: one small, club-like, covered with small denticles apically; two other lobes distinctly enlarged. Right paramere (Figs. 52–53). Paramere body: inner margin distinctly sinuate; apical process: lateral view: moderately curved; dorsal view: ellipsoidal in outline; medial process moderately developed, rounded. Left paramere (Figs. 54–55). Apical process: lateral view: relatively stout, straight; dorsal view: subapical incision shallow; extreme apex relatively broad, weakly rounded.
Female. Similar to male in coloration, structure, texture, and vestiture.
Measurements. ♀/♂ (n=2, holotype measurements second): Body. Length 4.7/3.7, width 2.00/1.65. Head. Length 0.83/0.70, width 0.98/0.925, interocular distance 0.43/0.33. Antenna. Length of segment I 0.4, II 1.35/1.23, III 0.55/0.53, IV 1.0/0.85. Labium. Length of segment I 0.63/0.56, II 0.63/0.58, III 0.45/0.52, IV 0.65/0.48. Pronotum. Length 0.9/0.8, width of anterior margin 0.65/0.60, length of lateral margin 0.78/0.73, width of posterior margin 1.47/1.27.
Etymology. Taken from the Latin “ laevigatus ” (smooth, polished) and refers to the impunctate pronotum.
Biology. Unknown.
Distribution. Venezuela (Amazonas) (Fig. 50).
