HOLOTYPE: 3, MEXICO: Guerrero: 2.1 mi NW of Cacahuamilpa [18.67484 ° N 99.5602 ° W], August 11, 1978, Plitt & Schaffner ( AMNH _ PBI 00184932 View Materials ). Deposited in the collection of the Instituto de Biología , Universidad Nacional Autónoma de Mexico, Mexico City, D.F. GoogleMaps

DIAGNOSIS: Recognized by body being more or less uniformly pale green to pale yellowish brown, hemelytral membrane with pale fuscous areas (fig. 4); vertex width subequal to length of antennal segment I; labium reaching or nearly reaching mesocoxa; width of pronotum greater than length of antennal segment II; metepisternum dorsal to evaporative area of scent gland without microtrichia; setae prominent. Similar to J. burserae , which shares several features of the male genitalia not found in other congeners, but distinguished by the darker green coloration and by the fuscous areas of the hemelytral membrane.

DESCRIPTION: Male: COLORATION: Generally pale yellowish brown and pale green. Head yellowish brown to green; antenna pale yellowish brown occasionally pale fuscous on segment III and IV; labium pale, dark fuscous apically. Dorsal surface of remainder of insect variably yellowish brown with dark green areas; membrane of hemelytron pale but usually with large areolar cell and area near margin of membrane pale fuscous. Pleural and sternal areas of body posterior to pronotum pale yellowish brown (teneral specimens with green tint). Legs pale, rarely with apex of hind femur fuscous. VESTITURE: Frons and vertex of head disc of pronotum, scutellum and corium with both erect and semierect setae; setae on antennal segments II–IV decumbent, length not longer than diameter of respective segment; semierect setae on tibiae longer than diameter of respective tibia; setae of abdomen longer and more dense. GENITA- LIA (fig. 36): Genital segment with bifurcate tergal process projecting from right side of midline on dorsal margin of aperture; tergal process flattened, truncate, with short Tshape projection on medial surface; ventro- posterior margin of capsule not modified. Left paramere C-shaped in dorsal view; with unmodified sensory lobe; diameter gradually expanded from base to mitten-shaped apex. Right paramere approximately equal in size to left paramere, diameter of paramere gently thickened at base, distal region curved dorsally with three long apical spines. Phallotheca cone shaped, 1/2 length of spiculum; aperture large, convoluted, open on dorsal surface; mesolateral margins of aperture with pair of medially directed pockets, left side of aperture with notch to accommodate basal spine of spiculum. Vesica with long, sinuate, trifurcate spiculum, base thick and sinuate, situated on dorsal surface of ductus seminis; apex of spicular trunk with long, medially serrate, needlelike branch on right side, middle and left side of apex with much shorter serrate or needlelike branches, middle of spiculum trunk with short, narrow branch [broken in preparation]; base of spiculum with narrow recurved branch.

Female: Color and vestiture same for male.

Female (n 5 13; average given first followed in parentheses by range): Length, 3.61 (3.36–4.00); width, 1.56 (1.38–1.76). Head length, 0.20 (0.18–0.24); width, 0.77 (0.72–0.82); vertex width, 0.33 (0.30–0.34). Length of antennal segment I, 0.28 (0.26– 0.30); II, 1.12 (0.98–1.27); III, 0.76 (0.74– 0.82); IV, 0.31 (0.26–0.36). Pronotal length, 0.66 (0.54–0.72); vertex width, 1.24 (1.06– 1.36). Cuneal length, 0.68 (0.62–0.74); width across base, 0.54 (0.43–0.60).

HOST PLANT: Unknown.

ETYMOLOGY: Named for its yellowishgreen coloration.

DISTRIBUTION: Known from three localities in northeastern Guerrero and southeastern Puebla (fig. 10E).

DISCUSSION: This is one of two species with green coloration. The other is J. burserae and a brief discussion of the similarities and differences is presented in that discussion. As with J. burserae , a few specimens appear to have lost of the green coloration and are more pale yellowish brown, which is probably the result of preservation. The majority of the specimens were taken in Guerrero; however, two females came from Puebla a few miles from where many J. burserae were collected.
