Jornandes jaredi   , new species Figures 3, 10D, 23

HOLOTYPE: 3, MEXICO: Puebla: 13.3 mi NE of Tehuitzingo [18.35 ° N 98.2833 ° W, 1078 m], July 13–14, 1974, Clark, Murray, Ashe , Schaffner ( AMNH _ PBI 00184923 View Materials ).

DIAGNOSIS: Recognized by head dark fuscous to black, sometimes posterior margin of vertex and areas contiguous with eye brown; pronotum, scutellum, and hemelytron dark fuscous to black, abdomen paler, antenna and legs pale yellowish brown (fig. 3); vertex wider than length of antennal segment I; eye sexually dimorphic, larger in the male; labium extending to mesocoxa; width of pronotum greater than length of antennal segment II; margins of corium 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. This species is similar to J. zapotecas   ; both have pale antennae and legs. Along with J. albipes   , these two species have small, apically serrate, vesical spiculae. Jornandes jaredi   and J. zapotecas   have large tergal processes on the right side of the genital aperture that are absent in J. albipes   . The relatively dense vestiture of the dorsum also indicates a close relationship. The larger size (2.88–3.1633; 2.96–3.24 ♀♀) and fine structure of the male genitalia serve to distinguish J. jaredi   from J. zapotecas   (2.50– 2.6833; 2.50–2.94 ♀♀). Jornandes jaredi   is known from moderate altitudes whereas J. zapotecas   was taken primarily at sea level.

DESCRIPTION: Male: COLORATION: Dorsum dark fuscous with pale antennae and legs. Head dark fuscous to black with brown areas on vertex near eyes and sometimes on posterior margin of vertex; antenna pale brownish yellow with fuscous markings at base of segment I. Thorax including mesoscutum, scutellum, and hemelytron dark fuscous to black. Corium frequently paler at extreme base, membrane of hemelytron with pale area adjacent to apex of cuneus. Legs pale yellowish brown, base of mesocoxa slightly fuscous at base. Abdomen dark fuscous. VESTITURE: Frons and vertex of head, disc of pronotum, scutellum, and corium with conspicuous setae, the length of which about as long as diameter of antennal segment II, pleuron of thorax almost devoid of setae; antennal segments II–IV with short decumbent setae; semierect spines of tibiae as long or longer than diameter of respective tibia; decumbent setae of abdomen longer and more dense. GENITALIA (fig. 23): Genital segment with narrow tergal processes to right of midline of dorsal margin of aperture; ventroposterior margin of capsule with acute notch; distal width of subgenital plate narrow, dorsal margin of plate slightly projecting beyond aperture of capsule. Left paramere C-shaped in dorsal view; relatively short, sensory lobe minimally produced, diameter gradually widening to expanded mitten-shaped apex. Right paramere slightly longer than left paramere, Jshaped, sensory lobe evident with slight thickening; diameter attenuate toward narrow, pointed apex. Phallotheca conical, length subequal to length of spiculum, aperture ovoid on right surface. Vesica relatively short; trunk of spiculum sinuate, thickened medially; distal region recurved with one serrate, needlelike branch, reaching to 1/3 length of spiculum; base attached slightly to right of dorsal surface on right side of sclerotized portion of ductus seminis.

Female: Color and vestiture same as for male.

MEASUREMENTS: Male (n 5 20; holotype given first followed in parentheses by average and range): Length, 3.10 (3.06, 2.88– 3.16); width, 1.16 (1.13, 1.10–1.16). Head length, 0.16 (0.16, 0.14–0.20); width, 0.74 (0.73, 0.70–0.76); vertex width, 0.28 (0.28, 0.26–0.30). Length of antennal segment I, 0.24 (0.24, 0.22–0.26); II, 0.86 (0.87, 0.82– 0.92); III, 0.66 (0.65, 0.60–0.68); IV, 0.34 (0.31, 0.30–0.34). Pronotal length, 0.50 (0.52, 0.50–0.54); width across base, 0.92 (0.96, 0.92–1.02). Cuneal length, 0.54 (0.55, 0.52– 0.60); width across base, 0.42 (0.38, 0.36– 0.42).

Female (n 5 13; average given first followed in parentheses by range): Length, 3.11 (2.96–3.24); width, 1.24 (1.12–1.28). Head length, 0.17 (0.14–0.20); width, 0.73 (0.70–0.74); vertex width, 0.33 (0.32–0.34). Length of antennal segment I, 0.23 (0.22– 0.24); II, 0.85 (0.76–0.90); III, 0.64 (0.58– 0.64); IV, 0.33 (0.28–0.40). Pronotal length, 0.54 (0.52–0.56); width across base, 0.99 (0.92–1.04). Cuneal length, 0.53 (0.50–0.56); width across base, 0.43 (0.38–0.44).

DISCUSSION: With the exception of a few restricted pale areas, the body is totally dark fuscous to black with contrastingly pale legs and antennae. Most specimens show a pale fuscous area at the extreme base of the corium, which can best be seen from the side. The setae on the corium are longer and denser than in most species.

HOST PLANT: Unknown.

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

DISTRIBUTION: Known from five localities in southwestern Puebla, eastern Oaxaca, and southern Guerrero (fig. 10D).
