HOLOTYPE: 3, Mexico: Oaxaca: 6 mi W of Tehuantepec [16.33333 ° N 95.32372 ° W], July 16, 1987, Kovarik, Schaffner ( AMNH _ PBI 00184934 ). Deposited in the collection of the Instituto de Biology , Universidad Nacional Autónoma de Mexico, Mexico City, D.F.

DIAGNOSIS: Recognized by head dark fuscous with pale yellowish brown on posterior margin of vertex and limited areas along eyes, pronotum and hemelytron dark fuscous to black, abdomen paler, antenna and legs yellowish brown (fig. 4); vertex width about equal to length of antennal segment I; eye sexually dimorphic being larger in the male; labium reaching mesocoxa; width of pronotum greater than length of antennal segment II; costal margins of hemelytron subparallel; setae on pronotum, scutellum, and corium conspicuous, about as long as diameter of antennal segment II; metepisternum dorsal to evaporative area of scent gland with microtrichia. Jornandes zapotecas is most closely related to J. jaredi and is separated from the latter by its smaller size and genitalic structure, especially with the smaller tergal process.

DESCRIPTION: Male: COLORATION: Generally dark fuscous to black with appendages, limited areas of head, yellowish brown. Head dark fuscous to black with carina of vertex, areas of frons along eyes, and variable pattern generally running from antennal base, along both sides of suture separating mandibular plate from maxillary plate paler; antenna pale yellowish brown, labium pale yellowish brown with apex dark fuscous. Thorax dark fuscous to black. Corium dark fuscous to black with restricted pale area at wing base, and membrane paler fuscous. Legs uniformly pale yellow, apices of tarsi pale fuscous. Evaporatorium pale fuscous. Abdomen usually dark fuscous but sometimes paler. VESTITURE: Prominent. Length of semierect setae on head, pronotum, and corium as long or almost as long as diameter of antennal segments; membrane sometimes with a few short setae. Setae on underside of abdomen slightly longer. GEN- ITALIA (fig. 38): Genital segment with short, smooth-margined, pointed tergal process located far right of midline on dorsal margin of aperture; ventroposterior margin of capsule with sharp notch on somewhat pointed ventral apex, subgenital plate moderately narrow distally, projecting dorsal to aperture of capsule. Left paramere C-shaped in dorsal view; sensory lobe not produced beyond diameter of paramere; diameter expanded to slightly expanded mittenlike apex. Right paramere size similar to left paramere; somewhat C-shaped; dorsal margin sinuate, body of paramere offset dorsally from base of paramere; distal region with small dorsally directed point. Phallotheca small, cone

00118212); scale 5 0.20 mm.

shaped, almost as long as vesical spiculum; aperture open widely on dorsal surface to narrowed apex. Vesica small; spiculum sinuate on basal half, thickened medially; length of distal recurved region 1/2 of spiculum body; spiculum somewhat concave subapically with serrate, sharply pointed apex; base wide, situated on dorsal surface of ductus seminis with produced sclerotized attachment to conjunctiva.

Female: Similar color and vestiture as male.

MEASUREMENTS: Male (n 5 4; those of holotype given first followed in parentheses by average and range): Length, 2.68 (2.59, 2.50–2.68); width, 1.00 (1.04, 1.00–1.10). Head length, 0.14 (0.14, 0.12–0.18); width, 0.70 (all); vertex width, 0.26 (0.25, 0.24–0.26). Length of antennal segment I, 0.22 (0.23, 0.22–0.24); II, 0.76 (0.77, 0.74–0.80); III, 0.58 (0.57, 0.54–0.60); IV, 0.36 (0.35, 0.32–0.36). Pronotal length, 0.46 (0.48, 0.46–0.50); width across base 0.84 (0.87, 0.82–0.90). Cuneal length, 0.46 (0.46, 0.44–0.48); width across base, 0.30 (0.31, 0.30–0.32).

Female (n 5 7; average followed in parentheses by range): Length, 2.76 (2.50– 2.94); width, 1.16 (1.08–1.20). Head length, 0.13 (0.10–0.16); width, 0.69 (0.66–0.72); vertex width, 0.31 (0.30–0.34). Length of antennal segment I, 0.23 (0.20–0.24); II, 0.77 (0.68–0.80); III, 0.59 (0.52–0.68); IV, 0.34 (0.28–0.38). Pronotal length, 0.54 (0.52– 0.56); width across base, 0.95 (0.90–1.00). Cuneal length, 0.45 (0.42–0.48); width across base, 0.36 (0.34–0.40).

DISCUSSION: The vestiture is very easily seen on specimens of this species. The vertex width is about equal to the length of antennal segment I. Jornandes zapotecas and J. jaredi have pale legs and antennae and long decumbent setae evenly distributed over the dorsum, especially on the scutellum and corium. This is one of the smaller species of the genus. Jornandes zapotecas is also similar in appearance to some small shining black Scalponotatus spp.

HOST PLANT: Ceiba parvifolia Rose ( Malvaceae , formerly Bombacaceae ).

ETYMOLOGY: Named for the indigenous people who inhabit the area.

DISTRIBUTION: Known from the type and an adjacent locality in southwestern Oaxaca (fig. 10A).
