August 6, 1988, Ferreira, Schaffner, Taken on Heliocarpus terebinthinaceus (DC.) Hochr. , det. Oswaldo Tellez [19]’90 ( AMNH _PBI 00184922). Deposited in the collection of the Instituto de Biología, Universidad Nacional Autónoma de Mexico, Mexico City, D.F.

DIAGNOSIS: Distinguished by pronotum reddish orange and hemelytron brownish orange, hemelytron usually with fuscous areas, scutellum reddish brown to dark fuscous, all femora dark fuscous except pale at apices, antenna pale (fig. 3); vestiture sparse, setae scattered, decumbent; vertex clearly wider than length of antennal segment I; labium reaching or nearly reaching metacoxa; width of pronotum greater than length of antennal segment II; hemelytron somewhat hyaline; metepisternum dorsal to evaporative area of scent gland with microtrichia.

DESCRIPTION: Male: COLORATION: Dorsum reddish orange to brownish orange with pale to dark fuscous areas. Head with vertex yellowish brown and frons, gena and base of clypeus more reddish orange, apex of clypeus dark fuscous, maxillary plate sometimes slightly darker than mandibular plate; antenna yellowish brown, base of segment I and segment IV usually pale fuscous; labium with segment I and apex dark fuscous. Pronotum reddish orange to brownish orange, yellowish brown on sides, rarely with central portion black and broad lateral areas reddish orange. Mesoscutum brownish orange; scutellum partially to entirely fuscous to black. Corium brownish orange with variable areas of pale fuscous coloration, membrane dark fuscous, paler centrally. Coxa dark fuscous, trochanter pale but with some pale fuscous areas, femora dark fuscous, yellowish brown near apices; tibiae and tarsi pale. Prosternum pale, meso- and metasterna dark fuscous, pleural areas yellowish brown, evaporatorium fuscous; underside of abdomen dark fuscous, some specimens slightly paler anteriorly. VESTITURE: Body mainly with decumbent, scattered setae, pale in color and somewhat inconspicuous, almost as long or longer than diameter of antennal segment II; antenna with uniformly decumbent setae; underside with vestiture longer and more dense; a few specimens with a few setae on membrane of hemelytron. GENI-

00118203); scale 5 0.20 mm.

TALIA (fig. 22): Genital segment with relatively large, apically bifurcate, smooth-margined, tergal process located far right of midline on dorsal margin of aperture; ventroposterior margin of capsule with deep notch, subgenital plate asymmetrically placed to left of aperture, distal portion narrow, not projecting beyond aperture of capsule. Left paramere stoutly C-shaped in dorsal view; sensory lobe not produced beyond diameter of paramere; diameter expanded to deeply notched mittenlike apex. Right paramere slightly longer than left paramere; dorsal margin sinuate, distal region sicklelike, at right angle with basal portion of paramere, distal region long, attenuate to sharply pointed apex. Phallotheca small, subrectangular, subequal in length to vesical spiculum; aperture open widely apically. Vesica small; body of spiculum sinuate, thickened medially; distal region marginally serrate, recurved basally, projecting laterally, pointed apically, and with length almost as long as body of spiculum.

Female: Membrane of hemelytron uniformly dark fuscous otherwise color and vestiture as in male.

MEASUREMENTS: Male (n 5 4; those of holotype given first followed in parentheses by average and range): Length, 2.94 (2.98, 2.86–3.10); width, 1.78 (1.79, 1.76–1.82). Head length, 0.14 (0.14, 0.12–0.14); width, 0.88 (0.89, 0.88–0.90); vertex width, 0.42 (0.42, 0.40–0.44). Length of antennal segment I, 0.20 (0.22, 0.20–0.22); II, 0.86 (0.87, 0.84– 0.92); III, 0.68 (0.69, 0.66–0.72); IV, 0.36 (0.38, 0.36–0.40). Pronotal length, 0.70 (0.73, 0.70–0.74); width across base, 1.38 (1.42, 1.38–1.46). Cuneal length, 0.62 (0.63, 0.62– 0.64); width across base, 0.56 (0.57, 0.56– 0.58).

Female (n 5 5; average followed in parentheses by range): Length 3.10 (2.94– 3.20); width, 1.85 (1.76–1.90). Head length, 0.18 (0.18–0.20); width, 0.90 (0.88–0.92); vertex width, 0.45 (0.44–0.46). Length of antennal segment I, 0.21 (0.20–0.24); II, 0.89 (0.86–0.90); III, 0.65 (0.62–0.68); IV, 0.38 (0.36–0.40). Pronotal length, 0.74 (0.74– 0.76); width across base, 1.42 (1.38–1.48). Cuneal length, 0.58 (0.56–0.58); width across base, 0.60 (0.58–0.64).

DISCUSSION: The variable fuscous-toblack coloration on the scutellum and corium makes this species somewhat difficult to describe. The scutellum varies from reddish orange, as on the pronotum, to entirely dark fuscous to black. The color of the clavus is more or less the same as the pronotum, whereas the embolium and corium usually exhibit various shades, usually pale to fuscous. The dark fuscous membrane is occasionally pale medially. A few setae are on the membrane of several specimens. This is the only species known to occur in the state of Zacatecas.

We have excluded three specimens from the paratype series. A male from southern Sinaloa state conforms to the above description, has identical male genitalic form as the holotype, but the absence of specimens from intervening areas questions its placement in the species. The male from Michoacan has identical male genitalia as the holotype, but is damaged with the head missing and the pronotum is mostly black, unlike the mostly orange-red pronotal coloration as in the holotype and paratypes. A female from the same collecting event has similar pronotal coloration as in the male.

HOST PLANT: Heliocarpus terebinthinaceus (DC.) Hochr. (Tiliaceae) .

ETYMOLOGY: Named after the plant genus from which these specimens were taken.

DISTRIBUTION: Known from three collection events, the type locality, in southern Zacatecas, southern Sinaloa, and central Michoacan (fig. 10A).
