NE of Tehuitzingo [18.35 ° N 98.2833 ° W,

1078 m], July 13–14, 1974, Clark, Murray, Ashe, Schaffner ( AMNH _PBI 00094249). Deposited in the collection of the Instituto de Biología, Universidad Nacional Autónoma de Mexico, Mexico City, D.F.

DIAGNOSIS: Recognized by large size; clypeus red or rarely fuscous, most of remainder of head and rest of body including legs yellowish brown to brown, scutellum darker than pronotum, antennal segment II uniformly dark fuscous, remaining segments dark fuscous with pale areas, hemelytron yellowish brown to fuscous (fig. 4); vertex clearly wider than length of antennal segment I; labium reaching or nearly reaching mesocoxa; width of pronotum greater than length of antennal segment II; corium somewhat hyaline; metepisternum with microtrichia extending dorsal to evaporatorium of scent gland.

DESCRIPTION: Male: COLORATION: Generally yellowish brown to brown with fuscous to reddish-fuscous areas. Head with vertex yellowish brown, frons brown or reddish brown, clypeus reddish to reddish fuscous, maxillary and mandibular plates yellowish brown; basal area of antennal segment I pale, fuscous apically, segment II dark fuscous, III and IV pale at base, remainder of segments dark fuscous; labium brown, dark fuscous at apex. Pronotum yellowish brown with area of calli reddish brown or almost orange. Mesoscutum yellowish brown; scutellum ranging from brown to dark fuscous. Corium ranging from yellowish brown to dark fuscous, paler toward costal margin and cuneal area; membrane fuscous. Legs with coxae and trochanters pale yellowish brown; femora yellowish brown, hind femur with fuscous area near apex on one specimen, tibiae yellowish brown, usually slightly fuscous basally, dark fuscous at apex, tarsi completely dark fuscous. Pleural and sternal areas of meso- and metathorax yellowish brown to dark fuscous, evaporatorium of scent gland pale or pale fuscous. Abdomen yellowish brown with varying degrees of fuscous coloration; discrete reddish brown marks on anterolateral margin of each sternite. VESTITURE: Head, pronotum, scutellum, and corium almost devoid of setae; pleural areas of meso- and metathorax, corium with

00094249); scale 5 0.20 mm.

sparse decumbent pale scattered short setae; setae on antennal segments II–IV decumbent, not longer than diameter of respective segments; semierect spines of tibiae as long or longer than diameter of respective tibia; decumbent setae of abdomen longer and more dense. GENITALIA (fig. 35): Genital segment with broad, triangular tergal process projecting from right side of midline of dorsal margin of aperture; apical portion of process with cuticular sculpturing and solitary seta; ventroposterior margin of capsule cleft; subgenital plate recessed, not protruding distally beyond aperture of capsule. Left paramere large, C-shaped in dorsal view; with broad, moderately produced basal tubercle on sensory lobe region; diameter of paramere gradually narrowed to middle, broadly expanded to large, round and flattened, mittenshaped apex, medial lobe narrower than lateral lobe. Right paramere large; diameter of paramere gradually thickened from base to sensory lobe region, narrowed to dorsally directed distal shaft; sensory lobe with small, pointed spine; shaft with several large spines; body of paramere with large dorsally directed, gradually attenuate lobe projecting from ventral medial surface. Phallotheca cylindrical, 1/2 length of spiculum; aperture broadly open on dorsal and right sides. Vesica with one long, narrow, bifurcate spiculum; in dorsal view ventral portion of bifurcation simple, without serration, shorter than multibranched dorsal half of bifurcation; base of spiculum broad, situated on dorsal surface of ductus seminis; basal process needlelike, slightly coiled.

Female: Color and vestiture same as for male.

MEASUREMENTS: Male (n 5 4; those of holotype given first followed in parentheses by average and range): Length, 4.72 (4.37, 4.08– 4.72); width, 2.06 (2.00, 1.88–2.10). Head length, 0.30 (0.25, 0.22–0.30); width, 1.08 (1.04, 1.00–1.08); vertex width, 0.54 (0.52, 0.48–0.54). Length of antennal segment I, 0.34 (0.34, 0.32–0.34); II, 1.34 (1.31, 1.22– 1.36); III, 0.90 (0.90, 0.82–0.98); IV, 0.36 (0.39, 0.36–0.44). Pronotal length, 0.88 (0.85, 0.82– 0.88); width across base, 1.66 (1.57, 1.50–1.66). Cuneal length 0.62 (0.61, 0.60–0.62); width across base, 0.76 (0.72, 0.66–0.76).

Female (single paratype): Length, 4.40; width, 2.40. Head length, 0.26; width, 1.12; vertex width, 0.56. Length of antennal segment I, 0.32; II, 1.28; III, 0.84; IV, 0.80. Pronotal length, 1.80; width across base, 1.72. Cuneal length, 0.72; width across base, 0.66.

DISCUSSION: This is the largest species of the genus. Four of the five available specimens are to varying degrees teneral, which may account for some of the variation given in the color description. The reddish to reddish-fuscous clypeus is a useful character in recognizing this species. The maxillary plate is not darker than the mandibular plate. The setae on the dorsum are short and inconspicuous; very few setae are present on the hemelytral membrane.

HOST PLANT: Unknown.

ETYMOLOGY: The name refers to the color variation exhibited by members of this species.

DISTRIBUTION: Known from two localities in southwestern Puebla and northeastern Guerrero (fig. 10E).
