 Description. Male. Head. Antenniferous tubercles small, armed with short spine slightly curved around base of antennal segment I; antennal segment I longer than 1.15 mm.   
Genital capsule. Posteroventral margin with broad, median convex shallow plate; lateral lobes rounded (Fig. 4). Paramere (Figs. 15–16).  
Dorsal color. Head, pronotum, scutellum, clavus, and corium dull yellow, with reddish brown punctures: antennal segment I bicolor, outer face black, inner face castaneous orange, segments II and III castaneous orange and IV black with basal joint and apical third dark orange; apex of tylus and jugae pale yellowish white; antenniferous tubercles and spine black to dark reddish brown; ocellar tubercle, postocular tubercle, head basally, and frontal angles black; humeral angles black; anterior and middle third of costal margin of corium yellowish white and apical third dull yellow; hemelytral membrane yellowish translucent with veins darker; connexivum yellowish white; dorsal abdominal segments black, except for dark yellow area around scent glands openings, and posterior margin of segment VII.  
Ventral color. Yellowish white; propleura, mesopleura, metapleura and abdominal sterna III to VII with a prominent black spot; abdominal sterna III and IV with an additional prominent black spot, set lateral to middle line and close to anterior margin; rostral segments black; apical third of rostral segment I dark yellow; coxae yellowish white with black spot; trochanters yellowish white; femora, tibiae, and tarsi pale orange; anterior and posterior lobe of metathoracic peritreme yellowish white.  
Integument. Head dorsally, pronotum, scutellum, clavus, and corium deeply punctate with small to large punctures; apical third of tylus, jugae, and connexivum impunctate; head ventrally, thorax, abdomen, male genital capsule and female genitalia with small, inconspicuous but definite punctures over entire surface; head dorsally, pronotal disk, pro-, meso-, and metasternum, middle third of abdominal sterna III to VII, male genital capsule, female genital plates, and upper border of connexivum densely clothed with erect to semi decumbent golden to silvery hairs; head ventrally, scutellum, clavus, corium, pro-, meso-, and metapleura, and lateral margins of abdominal sterna III to VII almost glabrous; antennal and rostral segments, and femora clothed with short to minute decumbent to erect silver hairs; tibiae and tarsi densely clothed with elongate silver hairs.  
Female. Habitus and color similar to male holotype.  
Genitalia. Abdominal sternite VII with plica and fissura; plica ‘U’ shaped; fissura almost reaching anterior margin of the sternite; gonocoxae I enlarged anteroposteriorly, in caudal view closed; paratergite VIII triangular, spiracle not visible; paratergite IX squarish, longer than VIII. Spermatheca. Receptacle spherical; duct heavy coiled; spermathecal duct with a large pumpkin-like dilation. Rostral segment I dark yellow with upper face black, and segments II to IV black; connexival segments VIII and IX and genital plates yellowish white; dorsal abdominal segments VIII and IX black; ventral punctures pale pink or yellowish white.  
Measurements. First male, then female (mm). Head length 1.24, 1.52; width across eyes 1.84, 2.08; interocular distance 0.96, 1.12; interocellar distance 0.64, 0.73; preocular distance 0.80, 0.89; length of antennal segments: I – 1.20, 1.36; II – 1.80, 2.00; III – 1.48, 1.52; IV – 2.04, 2.22. Pronotal length 2.44, 3.00; width across frontal angles 1.55, 1.80; width across humeral angles 2.84, 3.48. Scutellar length 1.24, 1.52; width 1.28, 1.58. Body length 11.18, 13.52.  
 Variation. i) Rostrum reaching anterior border of metasternum. ii) Rostral segment I pale yellow with or without black marks. iii) Rostral segments II to IV black or with dark orange or dark yellow longitudinal stripes. iv) Frontal and humeral angles black or dull yellow.   
 Differential diagnosis. Catorhintha sticta sp. nov., resembles C. lucida in general aspects; these species have the antenniferous tubercle armed exteriorly with a convoluted spine, thorax and abdominal sterna III to VII yellowish white with black discoidal spot, connexivum entirely yellowish white, and dorsal abdominal segments black with scars IV–V, and V–VI and posterior margin of male segment VII dark or pale yellow.   
 In C. sticta sp. nov. the external spine of antenniferous tubercle is shorter, not reaching antennal plate, ocellar tubercle black, antennal segment I bicolorous, inner face yellowish orange, outer face black to reddish brown, antennal segment IV black with basal joint and apical third dark orange, black discoidal spots at thorax and abdominal sterna III to VII conspicuously prominent, and posteroventral margin of male genital capsule with median convex shallow plate (Fig. 4). In C. lucida the external spine of antenniferous tubercle is elongate, touching or extending beyond antennal plate, ocellar tubercle, antennal segment I and IV, and rostral segments II to IV (apex of IV pale brown) pale yellowish orange, black discoidal spots at thorax and abdominal sterna III to VII smaller, and posteroventral margin of male genital capsule entire, not exposed at middle third (Fig. 5).   
 Etymology. From the Greek, ‘ stictos ’, meaning spotted, referring for the spotted ventral surface; adjective.   
 Habitat. Collected on Neea psychotrioides J. D. Smith (Nyctaginaceae).   
 Distribution. Mexico (Quintana Roo, Veracruz).
