Cylapocerus tucuruiensis Carvalho, 1989: 83 , Figs 7–8 (new species).

Cylapocerus tucuruiensis: CARVALHO & FROESCHNER (1994) : 489 (list); SCHUH (1995): 21 (catalog); GORCZYCA (2006b): 14 (catalog); SCHUH (2013) (online catalog).

Type material (not examined). BRAZIL: PARÁ: 1 J, “Tucuruí, Pará, BRASIL, 1979, M.Alvarenga col.” (Museu

Nacional, Rio de Janeiro, Brazil).

Material examined. VENEZUELA: AMAZONAS: 1 J 1 ♀, “Venezuela,T. F.Amaz., Cerro de la Neblina Basecamp,

140 m, 0°50′N, 66°10′W, 5 February 1985; Pyrethrin fogging of vine tangle; canopy of flood plain forest along Rio

Baria; R. Cocroft & W. Steiner” ( USNM).

Diagnosis. Recognized by the following combination of characters: antennal segment II as thick as segment I ( Fig. 55); pronotum broadly tinged with red laterally ( Figs 54, 55); corium with yellow patch medially ( Figs 54, 55); endosoma with three sclerites situated apically; sclerite es1 weakly arcuate, tapering; es2 nearly cylindrical, curved and tapering; es3 cylindrical, basally weakly curved ( Fig. 140 ); left paramere with sensory lobe strongly developed ( Fig. 141 ).

Most similar to C. amazonicus , C. antennatus , C. luridus and C. marginicollis in sharing antennal segment II thicker or as thick as segment I ( Figs 36, 38 , 43, 55). It can, however, be easily distinguished by the shape of the male genitalia.

Redescription. Male (composite description based on CARVALHO 1989 and the specimens mentioned below). Coloration ( Figs 54, 55, 65 ). Black with red, dark castaneous, and yellow areas. Head. Vertex dark brown, tinged with yellow; frons, clypeus, mandibular plate, and labrum dark brown black; frons tinged with yellow basally and basolaterally; gula, maxillary plate, and buccula yellow; antenna castaneous to black; segment III with yellowish annulation basally; labium black. Thorax. Pronotum dark castaneous to blackish, tinged with red laterally; collar yellow; humeral angle narrowly yellow. Mesoscutum and scutellum castaneous to dark castaneous, narrowly tinged with yellow apically. Thoracic pleura. Proepisternum dark brown; proepimeron yellow ventrally, red dorsally; remaining pleura black; posterior margin of mesepimeron yellow along entire length; metathoracic scent gland evaporative area yellow; peritreme fuscous apically. Hemelytron castaneous to blackish; corium with transverse, yellow patch medially; outer margin of clavus and inner margin of corium with yellow, narrow stripe along entire length; apical margin of corium and basal margin of cuneus yellow along entire length. Legs. Procoxa dark yellow tinged with red; meso- and metacoxae dark castaneous to dark brown, dirty yellow apically; remaining segments brown to dark brown. Structure, texture and vestiture ( Figs 54, 55, 65 , 146, 147 ). Dorsum covered with relatively long, semirecumbent and erect setae. Head. Antennal segment II thicker than segment I, gradually becoming narrower toward apex. Thorax. Pronotum covered with relatively long, erect setae; calli moderately developed. Scutellum covered with relatively long, erect setae; moderately convex. Hemelytron covered with moderately long, semirecumbent setae. Male genitalia ( Figs 140–144 ). Aedeagus ( Fig. 140 ). Endosoma with three sclerites (es1–es3) situated apically; es1 weakly arcuate, tapering; es2 nearly cylindrical, curved and tapering; es3 cylindrical, basally weakly curved. Left paramere ( Figs 141–143 ). Apical process thin, with both margins nearly straight, in lateral view apical process broadened basally and tapering; paramere body thin and straight in dorsal view; sensory lobe strongly developed. Right paramere ( Fig. 144 ). Apical process obtuse; paramere body broadened and arcuate at apical half, thinner and nearly cylindrical basally; basal process strongly developed, arcuate.

Female. Similar to male in structure, texture, and vestiture. Antennal segment II thinner than segment I, weakly broadened apically.
