Diagnosis

Male imago. (1) Dorsal portion of turbinate eyes oval ( Figure 11A View Figure 11 ); (2) forewing hyaline ( Figure 11E View Figure 11 ); (3) marginal intercalary veins single ( Figure 11E View Figure 11 ); (4) hind wing hyaline; (5) costal process of hind wing rounded ( Figure 11F View Figure 11 ); (6) abdominal sterna white, with anterolateral brown mark in each segment; (7) forceps segment I wide at base ( Figure 11C View Figure 11 ).

Female imago. (1) Forewing with yellowish green pigmentation at C, Sc, R 1 areas and wing base ( Figure 11H View Figure 11 ) (only yellowish in alcohol); (2) marginal intercalary veins single ( Figure 11H View Figure 11 ); (3) hind wing with 13–15 cross veins, basal half yellowish green ( Figure 11I View Figure 11 ) (yellowish brown in alcohol) ( Figure 11J, K View Figure 11 ); (4) hind wing with costal process rounded ( Figure 11J View Figure 11 ); (5) abdominal sterna with one dark mark anterolaterally ( Figure 11L View Figure 11 ); (6) abdominal terga green (yellowish brown in alcohol).

Mature nymph. (1) Antenna with spines; (2) anterior margin of labrum medially with subquadrangular small emargination (fig. 4 in Nieto 2008), setae of distal margin of labrum long and pointed; (3) maxillary palp scarcely longer than galea-lacinia (fig. 8 in Nieto 2008); (4) glossa subequal than paraglossa; (5) forefemur ventrally with trifid setae (fig. 10 in Nieto 2008) (6) foretarsus ventrally with trifid setae; (7) hind femur with curved and pectinate setae near ventral margin; (8) cerci with spines in all segments (fig. 15 in Nieto 2008); (9) terminal filament with spines in all segments.

Forewing hyaline ( Figure 11E View Figure 11 ), C and Sc areas opaque; veins white; stigmatic area with three to four cross veins touching subcostal vein and three to four veins not touching subcostal vein; marginal intercalary veins single, except between veins R 1 and R 2; length of each intercalary vein 0.3–0.7 × distance between adjacent longitudinal vein; length of forewing about 2.6 × width. Hind wing hyaline ( Figure 11F View Figure 11 ); with seven to nine cross veins, one marginal intercalary vein; costal process rounded. Abdomen. Terga white; tracheation black. Sterna white, with anterolateral brown mark in each segment. Caudal filaments white. Genitalia ( Figure 11C View Figure 11 ). Forceps white, segment I wide at base; 0.3 × length of segment II; distance between base of forceps 0.2 × distance between lateral margins of forceps. Forceps segment III apically truncate, 1.8 × as long as wide; 0.1 × length of segment II. Posterior margin of subgenital plate with small rounded projection.

Comments

The nymphs of C. gonzalezi   and C. cruentus   sp. nov. are similar, they can be distinguished by differences in the distal margin of labrum, which in C. gonzalezi   is straight (fig. 4 in Nieto 2008) and in C. cruentus   sp. nov. it is rounded ( Figure 6B View Figure 6 ); the segments of maxillary palp in C. gonzalezi   are subequal (fig. 8 in Nieto 2008) whereas in C. cruentus   sp. nov. the second segment is shorter (0.6 ×) than the first ( Figure 6F View Figure 6 ); abdominal segments V, VII and VIII with two parallel pale bands in C. gonzalezi   (fig. 3 in Nieto 2008) whereas in C. cruentus   sp. nov. these pale bands are absent ( Figure 8A View Figure 8 ). The female natural colour is green ( Figure 11D View Figure 11 ), after fixation the body colour changed to yellowish.
