Rhinocylapidius vittatus: Carvalho 1955b: 221, 1957: 23 , 1981: 463, Fig. 3–6 View FIGURE 3 View FIGURE 4 View FIGURE 5 View FIGURE 6 ; Schuh 1995: 35, 1038; Gorczyca 2006: 73

Diagnosis. Recognized by having the following combination of characters: overall coloration of dorsum pale; head, pronotum, and hemelytron with contrastingly yellow, longitudinal bands ( Fig. 2 View FIGURE 2 Q–R); clypeus entirely dark; labrum without spines; anterior lobe of pronotum flattened and sparsely punctate, with row of punctures laterally, each bearing single seta, longer than those present on remainder of anterior lobe ( Fig. 16 View FIGURE 16 C); scent gland evaporatory areas contrastingly pale yellow; claw toothed subapically; endosoma strongly membranous, with single sclerite whose proximal portion capturing sclerotized part of ductus seminis inside endosoma dorsally ( Fig. 15 View FIGURE 15 B). Rh. vittatus is most closely related to Rh. pallescens in sharing a pale body. It differs, however, by body coloration, pronotum shape, the claw toothed subapically, and by the male genitalia.

Redescription. Female. COLORATION ( Fig. 2 View FIGURE 2 Q–R). Dorsum brownish with regular, relatively broad, longitudinal, yellow stripes. Head. Varying from yellow with dark, longitudinal stripes dorsally and laterally to entirely dark brown; clypeus entirely dark brown to blackish; mandibular plates brownish, yellow apically; buccula yellow, dark medially; gula yellow with darker areas; antenna yellow brown; antennal segment I yellowish basally, then darker, reddish or yellowish with reddish, longitudinal stripes, sometimes segment is entirely brown; segment II ranging from yellowish brown to brown; segment III and IV brownish; rostrum yellow with brownish areas. Thorax. Pronotum. Yellow with four dark, brown, sometimes almost black, longitudinal stripes medially and laterally. Mesoscutum and scutellum. Yellow with dark, broad, triangular patch terminated subapically, sometimes scutellum almost entirely dark, yellow apically. Thoracic pleura. Proepimeron yellow with broad, brown, sometimes black, longitudinal stripes, sometimes proepimeron entirely dark, brown; mesepimeron and metepisternum fuscous, almost black, sometimes paler dorsally; scent gland evaporatory areas pale yellow. Hemelytron. Brown with yellow, rather narrow stripes on corium and clavus; embolium yellow, sometimes brownish; cuneus varying from yellowish red to almost entirely reddish or brownish. Legs. Yellowish; coxa pale yellow, femur mottled with dark, small patches, slightly red apically; tibia yellow, sometimes tinged with red apically; tarsus yellow. Abdomen. Varying from yellow with darker areas to entirely brown. STRUCTURE AND VESTITURE ( Fig. 2 View FIGURE 2 Q–R, 16A–F). Head. Matte, covered with pale, reclining, moderately dense setae; frons rugose medially; gula covered also with several very long, protruding setae; segment III and IV covered with moderately dense, relatively long, semidecumbent setae; rostrum long, slightly reaching beyond abdomen apically. Thorax. Pronotum. Pronotal collar without setae; anterior lobe flattened, sparsely and finely covered with punctation, pale setae, and with row of thick setae laterally, longer than those present on remainder of anterior lobe; posterior lobe covered with short, fine, pale setae. Mesoscutum and scutellum. Scutellum flattened, slightly rugose, sparsely covered with pale setae. Thoracic pleura. Proepimeron covered with fine and sparse punctation anteriorly. Hemelytron. Covered with short, fine, dense setae; yellow bands on hemelytron slightly swollen. Legs. Forecoxa more shining than other segments; femora and tibiae covered with relatively short, semidecumbent setae; claw toothed subapically.

Male. Similar to female but distinctly smaller; inner surface of segment II covered with dense, almost protruding, minute setae curved apically.

Male genitalia ( Fig. 15 View FIGURE 15 ). Endosoma strongly membranous, with single sclerite whose proximal portion captures sclerotized part of ductus seminis inside aedeagus dorsally
