Description. Male. Head. Antenniferous tubercle armed exteriorly with a small spine, convoluted and far from antennal plate; antennal segment I slender, longer than 1.15 mm.
Genital capsule. Posteroventral margin at middle third with short, raised plate, laterally convex ( Fig. 1 View Figs ). Paramere ( Figs. 9–10 View Figs ).
Dorsal color. Head, pronotum, scutellum, clavus, and corium dull yellow, with reddish brown punctures; antennal segment I dark reddish brown with inner face dark yellowish orange, segment II dark reddish brown, III dark reddish brown with basal joint dark yellow, and IV pale dark brownish orange with basal joint dark yellow; ocellar tubercle, postocular tubercle, head basally, and frontal angles of pronotum black to dark reddish brown; middle third of pronotal disk with pale yellow longitudinal stripe; apex of scutellum yellow; claval and corial veins pale yellow; hemelytral membrane yellowish translucid, veins darker; connexival segments III to VII dark brown to black with anterior third yellow; dorsal abdominal segments black.
Ventral color. Yellowish white; rostral segment I yellow with inner face black, and segments II to IV black; pro-, meso-, metapleura and abdominal sterna III to VII with prominent black discoidal spot; abdominal sterna III and IV with an additional black spot, lateral to midline and close to anterior margin; mesosternum yellow and laterally brown; coxae yellow with pale brown external spot; trochanters and femora yellow; tibiae yellow with distal third brown; first and second tarsomeres yellow with distal joint brown, and distal segment brown with basal joint yellow; genital capsule yellowish white with black mark at middle third; upper border of pleural abdominal sterna black with basal third yellow; abdominal spiracles yellow.
Integument. Head dorsally, pronotum, scutellum, clavus, and corium deeply punctate, with small to large punctures; connexivum impunctate; head ventrally, thorax, abdomen, male genital capsule, and female genital plates with small to large punctures; mesosternum impunctate; dorsal surface almost glabrous; ventral surface glabrous with middle third of mesosternum, metasternum, abdominal sterna III to VII, and genital capsule clothed with erect silver hairs; antennal and rostral segments and legs, clothed with short to long decumbent to erect silver hairs.
Female. Habitus and color similar to male holotype.
Genitalia. Fissura reaching anterior margin of abdominal sternite VII; plica ‘U’ shaped; gonocoxae I flat, triangular, inner margin barely overlapping, upper margin rounded. Antennal segment I entirely dark reddish brown; anterolateral margins of pronotum mostly black; apex of scutellum black; connexival segments VIII and IX black, with anterior angles yellow; dorsal abdominal segments VIII and IX black; punctures of pro-, meso-, metapleura, and abdominal sterna pale to dark pink.
Measurements. First male, then female (mm). Head length 1.40, 1.60; width across eyes 2.00, 2.04; interocular distance 1.00, 0.98; interocellar distance 0.52, 0.50; preocular distance 0.88, 0.88; length of antennal segments: I – 1.24, 1.26; II – 1.68, 1.72; III – 1.48, 1.48; IV – 2.40, 2.28. Pronotal length 2.68, 2.68; width across frontal angles 1.48, 1.60; width across humeral angles 2.96, 3.08. Scutellar length 1.28, 1.32; width 1.32, 1.36. Body length 12.12, 12.38.
Differential diagnosis. This species resembles C. semialba in having the antenniferous tubercle armed exteriorly with a convoluted spine, femora entirely yellow, thorax and abdominal sterna III to VII yellowish white with prominent black discoidal spot, and connexival segments VI and VII bicolorous, black with anterior third yellow.
In C. bellatula sp. nov., the external spine of antenniferous tubercle is shorter, not touching the antennal plate, antennal segment I and rostral segments I to IV black to dark reddish brown, and the posteroventral margin of male genital capsule has at middle third a short raised plate ( Fig. 1 View Figs ). In C. semialba the external spine of antenniferous tubercle is elongate, touching or extending beyond antennal plate, antennal segment I bicolorous with outer face reddish brown, and inner face dark yellow, rostral segments I to IV yellow (apex of IV black), and posteroventral margin of male genital capsule with broad, elongate and convex medial plate ( Fig. 3 View Figs ).
Etymology. From the Latin adjective ‘ bellatulus ’, meaning pretty, beautiful; adjective.
Distribution. French Guiana.
