HOLOTYPE: 3, MEXICO: Puebla: 14 mi N of Acatlan [19.00658 ° N 97.90422 ° W, 2262 m], August 12, 1978, Plitt and Schaffner, Taken on Bursera submoniliformis Engl.   , det. Oswaldo Tellez [19]’97 ( AMNH _ PBI 00184919 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 pale greenish to pale yellowish brown dorsally, antennal segments pale to pale fuscous, clypeus pale, underside including legs usually pale yellowish brown (fig. 2); pale semierect setae; vertex width subequal to length of antennal segment I; labium not reaching mesocoxa; width of pronotum greater than length of antennal segment II; metepisternum dorsal to evaporative area of scent gland without microtrichia. Similar to J. viridulus   , but J. burserae   is distinguished by the pale greenish or pale yellowish brown with the membrane of the hemelytron uniformly pale, whereas J. viridulus   is darker green and the membrane has pale fuscous to fuscous areas. The males of both species have similar genitalia with respect to the right paramere, phallotheca, and vesica, which are not found in the other spp. of Jornandes   .

DESCRIPTION: Male: COLORATION: Generally pale yellowish brown to pale green with few fuscous markings. Clypeus pale, antennal segments pale yellowish brown, sometimes pale fuscous; labium pale with dark fuscous apex. Remainder of body yellowish brown, frequently pale green; apical tarsomere dark fuscous, membrane of hemelytron pale. VESTITURE: Head, disc of pronotum, scutellum, and corium with semierect setae, most of which are longer than diameter of antennal segment II; pleural regions of thorax with sparse, short decumbent setae on antennal segments II–IV not longer than diameter of respective segments; spines on tibiae slightly longer than diameter of respective tibia; decumbent setae of abdomen longer and more dense. GENITALIA (fig. 14): Genital segment with broad, truncate, serrate, crestlike, medially placed tergal process on dorsal margin of aperture; ventroposterior margin of capsule smoothly notched, distal width of subgenital plate narrow, slightly projecting distal to aperture of capsule. Left paramere C-shaped in dorsal view; roughly of equal diameter, narrowed before expanded mittenlike apex. Right paramere approximately 1/4 longer than left paramere, elongate with sinuate dorsal margin of sensory lobe, distal half of paramere with truncate, spinose apex. Phallotheca conical, subequal in length to vesical spiculum; aperture open widely on middorsal surface to apex; left margin with notch to accommodate medial spine of spiculum. Vesica with long, sinuate, trifurcate spiculum, base sinuate; situated on dorsal surface of ductus seminis; apex of trunk of spiculum with long, needlelike branch on right side [broken in preparation]; middle of apex with short, recurved branch, needlelike branch just basal to apex of spiculum [broken in preparation]; base of spiculum with long, narrow recurved branch.

Female: Color and vestiture same as for male.

MEASUREMENTS: Male (n 5 20; those of holotype given first followed in parentheses by average and range): Length, 3.80 (3.82, 3.56–4.00); width, 1.46 (1.47, 1.42–1.52). Head length, 0.22 (0.20, 0.18–0.22); width, 0.80 (0.80, 0.78–0.82); vertex width, 0.32 (0.31, 0.28–0.32). Length of antennal segment I, 0.30 (0.29, 0.28–030); II, 1.08 (1.08, 1.02– 1.16); III, 0.80 (0.75, 0.68–0.82); IV, 0.28 (0.28, 0.24–0.36). Pronotal length, 0.66 (0.64, 0.60–0.66); width across base, 1.18 (1.20, 1.16–1.24). Cuneal length, 0.76 (0.74, 0.68– 0.76); width across base, 0.50 (0.49, 0.46– 0.52).

Female (n 5 20; average given first followed in parentheses by range): Length, 3.87 (3.00–4.10); width, 1.56 (1.46–1.64). Head length, 0.23 (0.20–0.24); width, 0.80 (0.76–0.82); vertex width, 0.34 (0.32–0.36). Length of antennal segment I, 0.29 (0.28– 0.30); II, 1.07 (1.04–1.10); III, 0.75 (0.70– 0.82); IV, 0.29 (0.26–0.34). Pronotal length, 0.64 (0.60–0.66); width across base, 1.25 (1.16–1.30). Cuneal length, 0.71 (0.64–0.78); width across base, 0.52 (0.50–0.54).

DISCUSSION: This species is similar to J. viridulus   . Characters common to both species include: usually some greenish coloration; lack of fuscous coloration on apex of clypeus, maxillary plate, and antenna; vertex width and length of antennal segment I more or less subequal; semierect setae on dorsum longer than those found on most species of the genus; and flattened corium.

It is probable that all specimens were pale green at the time of collecting, but some have lost the greenish tint in preservation. Five additional males, conspecific with the holotype, are excluded from the paratype series because of their poor condition due to alcohol preservation. This species and J. viridulus   are the only pale yellowish brown or pale green species known in the genus. The cuticular sculpturing is more difficult to see than in most species.

HOST PLANT: Bursera submoniliformis Engl.   ( Burseraceae   ).

ETYMOLOGY: Named for the plant genus from which some of the specimens were taken.

DISTRIBUTION: Known from five localities in southeastern Puebla and Guerrero (fig. 10B).
