Cylapocoris tiquiensis Carvalho

( Figures 12 , 22 , 36 , 61 , Table 1)

Cylapocoris tiquiensis Carvalho 1954: 508 , Pl. I, Fig. 5 , Pl. 2, Figs. l–2, 5 (n. sp.); Carvalho 1957: 28 (catalog); Carvalho & Gomes 1971: 485, 487 (diag., key); Carvalho & Froeschner 1987: 154 (list); Schuh 1995: 22 (catalog); Cherot & Pauwels 2000: 7 (list); Gorczyca 2006b: 28 (catalog).

Diagnosis. Recognized by the dorsal coloration pale, yellowish brown ( Fig. 12 ), the antennal segment II strongly thickened and contrastingly black at apical half ( Figs. 12 , 22 ), and the endosoma spinose (Carvalho 1954: Pl. I, Fig. 5 ).

Most similar to C. sulinus in sharing similar body size and pale coloration of dorsum ( Fig. 11 ). C. tiquiensis can, however, be easily distinguished by the uniformly yellowish brown dorsal coloration and the thickened and blackened apical half of antennal segment II ( Figs. 12 , 22 ).

Redescription. Male. COLORATION ( Figs. 12 , 22 ). Dorsal surface yellowish brown with castaneous areas. Head. Mostly blackish to fuscous with indistinct, yellowish tinges; antennal segment I and basal half of antennal segment II dirty yellowish, remainder of segment II black; segment III and IV dirty yellowish fuscous; labium dirty yellowish. Thorax. Pronotum. Yellowish brown tinged with fuscous at anterior angles and lateral portion of pronotal calli. Mesoscutum and scutellum. Yellowish brown. Thoracic pleura. Yellowish brown. Hemelytron. Yellowish brown. Legs. Yellowish with brownish areas. Abdomen. Yellowish brown. STRUCTURE, TEXTURE, AND VESTITURE ( Figs. 12 , 22 , 36 ). Head. Shiny, almost glabrous; antennal segment I somewhat narrowed at basal one fourth, remainder of segment I cylindrical; segment II covered with dense, semierect setae, with basal half almost cylindrical, apical half distinctly thickened; segment III and IV thin, covered with long, protruding setae; labium thin and long, reaching apex of abdomen. Thorax. Pronotum. Punctation indistinct, shallow. 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. Legs. Tarsi two-segmented; pretarsal claw not toothed subapically.

Male genitalia (from Carvalho 1954). Aedeagus (Carvalho 1954, Pl. I, Fig. 5 ). Endosoma spinose, theca present. Left paramere (Carvalho 1954, Pl. II, Fig. 2 ). Curved; ended by a hook-like process, beset with setae on dorsal surface.

Measurements. ♀/♂ (based on Carvalho 1954 and the AMNH specimen, holotype measurements second): Body. Length 4.0/3.6, width 1.5/1.5. Head. Length 0.7/0.6, width 0.8, diameter of eye in dorsal view 0.18. Antenna. Length of segment I 0.5/0.4, II 1.1/1.0, III 0.7, IV 0.8. Labium. Length of labium 2.4. Pronotum. Length 0.7, width of posterior margin 1.2.

Biology. Unknown.

Distribution. Brasil (Amazonas), Peru (Tambopata) ( Fig. 61 ).

Type material. Allotype ♀: Amazonas, Brasil, Taracua, 6–49, JCM Carvalho col; Allotype [reddish label]; Carvalho to Drake Coll. 1993 (USNM) ( Figs. 12 , 22 ).

Additional examined specimens. 1 ♀: Peru: Tambopata Reserve, 30 km SW Puerto Maldonado, IX/19-X/10/ 84; 12º12’S, 69º16’W Trop[ical] Moist F[o]r[e]st., D.A. Grimaldi; reared from fungus: Auricularia (AMNH); 1 ♀: Tiquié, Amazonas, JCM Carvalho Col. 1949 (USNM).
