HOLOTYPE: 3, MEXICO: Puebla: 5 mi SE of Izucar de Matamoros [18.54858 ° N

98.41242 ° W], July 20, 1984, Carroll, Schaffner, Friedlander ( AMNH _PBI 00184926). Deposited in the collection of the Instituto de Biología, Universidad Nacional Autónoma de Mexico, Mexico City D.F.

DIAGNOSIS: Recognized by head and antennal segments I and II yellowish brown, apex of clypeus dark fuscous to black, pronotum yellowish brown occasionally with variable fuscous coloration medially, hemelytron and abdomen primarily dark fuscous to black (fig. 3); vertex wider than length of antennal segment I; labium reaching or barely reaching mesocoxa; width of pronotum greater than length of antennal segment II; metepisternum dorsal to evaporative area of scent gland with microtrichia. Jornandes nathani is most similar to J. tehuacanensis , but antennal segments I and II of J. nathani are pale, whereas segment II is dark fuscous or dark on the base and apex in J. tehuacanensis . The eye of the male is conspicuously larger in J. nathani than in J. tehuacanensis .

DESCRIPTION: Male: COLORATION: Dorsum yellowish brown and dark fuscous to black. Head, yellowish brown with maxillary plate yellowish brown to fuscous, and extreme apex of clypeus pale fuscous; antenna pale yellowish brown; frequently segments III and IV fuscous; labium with segment I and IV dark fuscous, remainder yellowish brown. Pronotum yellowish brown, occasionally with fuscous coloration medially. Mesoscutum dark fuscous, sometimes paler laterally; scutellum dark fuscous to black. Hemelytron fuscous to dark fuscous with base yellowish brown, membrane usually pale medially, remainder fuscous. Legs pale yellowish brown with meso- and metacoxae pale fuscous basally, tarsi fuscous at apex. Meso- and metapleuron and sternum ranging from yellowish brown to dark fuscous with pale brown coloration primarily on mesopleuron. Abdomen dark fuscous to black. VESTITURE: Head, disc of pronotum, scutellum, and corium with conspicuous setae, the length of which about as long as diameter of the antennal segment II, pleuron of thorax almost devoid of setae, antennal segments II–IV with short decumbent setae; semierect spines on tibiae as long or longer than diameter of respective tibia; decumbent setae of abdomen longer and more dense. GENITALIA (fig. 27): Genital segment with pair of pointed tergal processes placed right and left of midline on dorsal margin of aperture, right process longer than, left process; ventroposterior margin of capsule flattened, flangelike, subgenital plate asymmetrically placed near left paramere fossa, moderately wide distally, distal to aperture of capsule. Left paramere C-shaped in dorsal view; shorter distally than in other species of Jornandes , diameter abruptly widened at expanded mittenlike apex, subapical dorsal margin of paramere protruding. Right paramere slightly larger than left paramere, T-shaped in lateral view; sensory lobe not modified; apex of paramere with large, pointed dorsal lobe and slightly shorter, pointed ventral lobe. Phallotheca subrectangular, subequal in length to vesical spiculum; aperture sinuate, widely open from base of right side across dorsal surface to apex and left of apex. Vesica with long, sinuate, bifurcate spiculum, base strongly sinuate, situated on dorsal surface of ductus seminis; trunk of spiculum wide medially, apex of trunk with somewhat recurved, needlelike, serrate branches; base of spiculum with flattened, truncate process.

Female: Color and vestiture same as for male.

MEASUREMENTS: Male (n 5 14; holotype given first followed in parentheses by average and range): Length, 3.44 (3.49, 3.20– 3.70); width, 1.56 (1.62, 1.50–1.70). Head length, 0.20 (0.21, 0.18–0.24); width, 0.90 (0.89, 0.86–0.90); vertex width, 0.34 (0.33, 0.30–0.34). Length of antennal segment I, 0.28 (0.27, 0.24–0.30); II, 1.20 (1.16, 1.06– 1.22); III, 0.90 (0.83, 0.76–0.90); IV, 0.40 (0.38, 0.34–0.42). Pronotal length, 0.64 (0.64, 0.62–0.68); width across base, 1.26 (1.29, 1.18–1.36). Cuneal length, 0.64 (0.66, 0.60– 0.70); width across base, 0.50 (0.52, 0.48– 0.54).

Female (n 5 20; average given first followed in parentheses by range): Length 3.32 (3.08–3.58); width, 1.70 (1.60–1.88). Head length, 0.23 (0.20–0.28); width, 0.87 (0.82–0.90); vertex width, 0.40 (0.36–0.42). Length of antennal segment I, 0.26 (0.24– 0.28); II, 1.06 (0.96–1.14); III, 0.73 (0.68– 0.84); IV, 0.38 (0.34–0.42). Pronotal length, 0.64 (0.60–0.70); width across base, 1.31 (1.22–1.38). Cuneal length, 0.59 (0.52–0.66); width across base, 0.55 (0.48–0.60).

DISCUSSION: Specimens from 6 mi E of Xochipala have the maxillary plate and much of the pleural and sternal regions of the thorax yellowish brown; these areas on specimens from other localities are fuscous to black. Jornandes nathani is one of six species having the scutellum and hemelytra dark fuscous to black and the pronotum a dull or bright shade of yellowish orange to yellowish brown. This species is most similar to J. tehuacanensis , which is also in the group. Both species share similarities in color and, importantly, the rather even distribution

of short decumbent but conspicuous setae on the scutellum and corium. The structure of the male genitalia of J. nathani is somewhat similar to that of J. rachelleae , especially the form of the vesical spiculum. J. rachelleae is also in this group of six species.

HOST PLANT: Unknown.

ETYMOLOGY: Name in honor of the second author’s son Eric Nathan.

DISTRIBUTION: Known from five localities in northern Guerrero and western Puebla (fig. 10D).
