DIAGNOSIS: Recognized by antennal segment I being primarily yellowish brown, with head, remaining segments fuscous to dark fuscous, anterior 2/3 of pronotum yellowish brown with remainder whitish or pale, scutellum and adjacent areas of clavus dark fuscous to black, corium pale with prominent dark fuscous band more or less parallel to claval suture from embolium to inner corner of cuneus, apex of cuneus dark fuscous, legs mainly pale yellowish brown (fig. 3); eye large in male; antennal segment I more or less subequal to vertex width; antennal segment II linear, about as long as width of pronotum; labium short, reaching procoxa; metepisternum dorsal to evaporative area of scent gland with microtrichia. Base coloration, but not pattern, similar to J. ceibae . Distinguished by the color of the scutellum: J. susanae has a dark scutellum whereas in J. ceibae it is pale. Jornandes ceibae and J. susanae also share certain male genitalic features (see discussion of J. ceibae ).

DESCRIPTION: Male: COLORATION: Generally boldly patterned with yellowish brown, white, and black. Head yellowish brown to brown; clypeus dark fuscous except at base, maxillary plate fuscous; basal antennal segment of head with some pale fuscous spots or partial rings especially at apex, remaining segments dark fuscous; labium pale brown with both base and apex dark fuscous. Pronotum with anterior 2/3 yellowish brown, remainder whitish or pale. Mesoscutum pale brown, scutellum dark fuscous to black. Corium pale with dark fuscous areas consisting of a broad band on clavus immediately adjacent to scutellum and another broad band along radial vein area that begins at emboliar suture and extends posteriorly to cuneal suture and membrane; emboliar area pale brown; cuneus whitish with apex dark fuscous; membrane pale with margin fuscous forming a band on apex of membrane, areolar veins dark fuscous. Legs pale brown with a pale fuscous spot near apex of hind femur; tarsi dark fuscus apically. Propleuron pale brown, paler pos- teriorly; mesopleuron and sternum shining dark fuscous; metapleuron pale brown with evaporative area dark fuscous; underside of abdomen pale brown with fuscous to dark fuscous areas especially behind metacoxa. VESTITURE: Head and thorax, except for appendages, with very short, mostly decumbent setae, those of corium more or less evenly distributed, sparse, setae not longer than diameter of antennal segment II; setae on antennal segments II–IV not longer than diameter of respective segments; semierect setae of tibiae about as long as diameter of respective tibia, decumbent setae of abdomen long and more dense. GENITALIA (fig. 33): Genital segment with short, but broadly projecting tergal process from midline of dorsal margin of aperture, entire margin or process minutely serrate; ventroposterior margin of capsule with acute notch, subgenital plate asymmetrically positioned toward left paramere fossa, distal portion projecting dorsal to aperture. Left paramere C-shaped in dorsal view; sensory lobe slightly produced, paramere with moderately wide diameter, gradually expanded to wider mitten-shaped apex, beyond subapical constriction. Right paramere three times as long as left paramere; diameter widest at base, sensory lobe with long, narrow, smooth, apically pointed process; remainder of paramere, long, tubelike with uniform diameter throughout, apex broadly rounded with surface on minute spinules. Phallotheca subrectangular, sinuate, length equal to length of spiculum; aperture wide, open from middle of right side to broadly open apex. Vesica small; spiculum stout, sinuate, and trunklike, base situated widely on dorsal surface of ductus seminis; base of spiculum without process; distal region greatly expanded, dorsal margin with row of spinules and narrow, serrate, subapical spine.

Female: Color and vestiture same as for male; sometimes antennal segment II broadly pale except at base and variable distal region.

MEASUREMENTS: Male: (n 5 20; holotype given first followed in parentheses by average and range): Length, 3.46 (3.54, 3.36– 3.82); width, 1.48 (1.53, 1.46–1.60). Head length, 0.22 (0.22, 0.18–0.26); width, 0.92 (0.91, 0.88–0.94); vertex width, 0.28 (0.28, 0.26–0.32). Length of antennal segment I, 0.30 (0.33, 0.30–0.36); II, 1.18 (1.22, 1.14– 1.32); III, 1.02 (0.99, 0.94–1.12); IV, 0.48 (0.47, 0.42–0.56). Pronotal length, 0.58 (0.61, 0.56–0.64); width across base, 1.22 (1.22, 1.16–1.26). Cuneal length, 0.60 (0.61, 0.56– 0.62); width across base, 0.48 (0.50, 0.46– 0.54).

Female (n 5 20; average given first followed in parentheses by range): Length, 3.60 (3.46–3.82) width, 1.65 (1.56–1.84). Head length, 0.22 (0.20–0.24); width, 0.89 (0.86–0.90); vertex width, 0.34 (0.32–0.36). Length of antennal segment I, 0.33 (0.30– 0.34); II, 1.23 (1.16–1.34); III, 0.97 (0.88– 1.06); IV, 0.49 (0.42–0.52). Pronotal length, 0.64 (0.60–0.68); width across base, 1.30 (1.24–1.48). Cuneal length, 0.61 (0.56–0.64); width across base, 0.53 (0.52–0.56).

DISCUSSION: The attractive color pattern found in J. susanae is unique among members of the genus. It is similar to that of J. ceibae in that the coloration (off-white and dark fuscous) is the same although the patterns are somewhat different. The head has a color pattern that is similar to that of J. cruralis and several other species and that consists of a fuscous band running from the anterior margin of an eye, along the maxillary plate, across the apex of the clypeus, and around to the other eye. Jornandes susanae is one of a few species in which antennal segment I is subequal in

length to the width of the vertex. In addition, it is one of three species having antennal segment II subequal in length with the width of the pronotum. The sculpturing of the corium is easily seen; the setae on the corium are short and sometimes the hemelytral membrane has two or three setae. The medial tergal process, sinuate vesical spiculum, narrow apical notch of the left paramere of the male genitalia are shared with J. ceibae ; however, the wider tergal process, the wider medial region of the vesical spiculum and elongate right paramere are diagnostic of J. susanae .

HOST PLANT: Unknown.
