Type material. HOLOTYPE: J, ‘ FRENCH GUIANA, 38 km SE Roura on Kaw rd, 256 m, 04°34′214″S-052°09′556″W, m. v. light , 4.xii.2002, J. E. Eger’ ( UNAM) . Paratypes: 1 J 2 ♀♀, same label data as holotpe ( FSCA, UNAM).

Description. Male. Head. Antenniferous tubercle armed externally with a small spine, convoluted, and far from antennal plate; antennal segment I medium size, shorter than 1.10 mm, and relatively slender.

Genital capsule. Posteroventral margin with broad sinuate middle plate, laterally convex ( Fig. 8 ). Paramere ( Figs. 17–18 ).

Dorsal color. Head, pronotum, and scutellum dull yellow with reddish brown punctures; antennal segment I with outer face reddish brown and inner face pale yellowish orange, segments II to IV pale yellowish orange; ocellar tubercle, postocular tubercle, head basally, frontal angles, anterolateral borders and humeral angles black; middle third of pronotal disk with dull yellowish longitudinal stripe; apex of scutellum yellow; clavus and corium dull yellow with reddish brown punctures; claval and corial veins paler; hemelytral membrane yellowish translucid, veins darker; connexival segment III yellow, and IV to VII yellow with posterior half or posterior third brown; dorsal abdominal segments black with scars IV–V and V–VI dark yellow.

Ventral color. Yellowish white; rostral segments I to IV yellow (apex of 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 discoidal spot, lateral to midline and close to anterior margin; mesosternum yellowish white and laterally shiny pale orange; metasternum yellowish white and laterally with brown spot; anterior and posterior lobe of metathoracic peritreme yellowish white; coxae yellow with external pale brown spot; trochanter, femora, tibiae, and tarsi shiny yellowish orange; pleural abdominal margins II to IV yellow, V to VII yellow with posterior half or posterior third pale brown; genital capsule yellowish white with black spot at middle third.

Integument. Head dorsally, bucculae, pronotum, pro-, meso-, metapleura, scutellum, clavus, and corium deeply punctate with small punctures; connexivum impunctate; head ventrally (except bucculae), pro-, meso-, metasternum, abdominal sterna, genital capsule, and female genital plates impunctate or scattered with tiny punctures inconspicuous; dorsal surface almost glabrous; ventral surface glabrous except mesosternum, metasternum, middle third of abdominal sterna, genital capsule and female genital plates 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 visible, ‘U’ shaped; gonocoxae I triangular, inner margin raised, not overlapping, upper margin rounded. Antennal segment IV dark orange with basal joint pale yellowish orange; anterior lobe of metathoracic peritreme pale brown or yellowish white, posterior lobe yellowish white; connexival segment III yellow with posterior third black; connexival segments VIII and IX black with anterior angle yellow; dorsal abdominal segments black; pleural abdominal margin III yellowish white, IV to VII yellowish orange with posterior third black to pale brown; and genital plates yellowish white.

Measurements. First male, then female (mm). Head length 1.34, 1.44; width across eyes 1.88, 1.90; interocular distance 0.98, 1.00; interocellar distance 0.50, 0.54; preocular distance 0.80, 0.81; length of antennal segments: I – 1.02, 1.04; II – 1.60, 1.60; III – 1.40, 1.40; IV – 2.16, 2.24. Pronotal length 2.48, 2.64; width across frontal angles 1.52, 1.56; width across humeral angles 2.80, 2.94. Scutellar length 1.20, 1.28; width 1.22, 1.32. Body length 10.46, 11.68.

Differential diagnosis. Closely related to C. bellatula sp. nov., described above. Both species recorded from French Guiana have the antenniferous tubercle armed exteriorly with a convoluted spine far from the antennal plate, 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. tumula sp. nov., the antennal segment I is bicolorous with outer face reddish brown and inner face pale yellowish orange, antennal segments II to IV yellowish orange, rostral segments II to IV yellow (apex of IV black), and the posteroventral margin of male genital capsule with broad sinuate middle plate ( Fig. 8 ). In C. bellatula sp. nov. the antennal segments I to IV and rostral segments II to IV are entirely black to dark reddish brown, and the posteroventral margin of male genital capsule at middle third with short, raised plate ( Fig. 1 ).

Etymology. From the Latin ‘ tumulus ’, meaning raised, referring to the stout spine raising on male fore trochanter; adjective.

Distribution. French Guiana.
