HOLOTYPE: 3, MEXICO: Michoacan: 22 mi NE of Arteaga [18.6927 ° N 102.1782 ° W],

July 31, 1988, elev. 3,000 ft [914 m], Ferreira, Schaffner ( AMNH _PBI 00094289). Deposit- ed in the collection of the Instituto de Biología, Universidad Nacional Autónoma de Mexico, Mexico City, D.F.

DIAGNOSIS: Distinguished by body dark fuscous to black, occasionally with paler coloration on vertex and mandibular plate, antenna pale, femora dark fuscous with apices pale, tibiae pale (fig. 3); robust in general appearance; vertex clearly wider than length of antennal segment I; apical two antennal segments about as wide as basal two segments; labium barely reaching mesocoxa; width of pronotum much greater than length of antennal segment II; metepisternum dorsal to evaporative area of scent gland with microtrichia.

DESCRIPTION: Male: COLORATION: Dorsum dark fuscous to black with paler areas on head and appendages. Head variable shades of fuscous, vertex often pale yellowish brown, with frons darker and clypeus dark fuscous, mandibular plate often more reddish than fuscous, maxillary plate darker; antenna pale yellowish brown; labium with basal segment reddish fuscous, remainder of labium pale yellowish except for dark fuscous apex. Thorax including hemelytron and abdomen dark fuscous to black. Coxae, trochanters, and most of femora dark fuscous to black, apices of femora, tibiae and tarsi pale yellowish brown. VESTITURE: Head, pronotum, sides of thorax, and hemelytron with sparse, decumbent inconspicuous setae; antennal segments with decumbent setae; setae on abdomen prominent and longer; setae on membrane of hemelytron visible on most specimens. GENITALIA (fig. 25): Genital segment with moderately long, smooth-margined, gently curved and pointed tergal process located just right of midline on dorsal margin of aperture; ventroposterior margin of capsule with small notch, subgenital plate small, not 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, medial lobe large. Right paramere size similar to left paramere; somewhat C-shaped; dorsal margin sinuate, slightly expanded basal portion offset laterally from insertion of paramere; distal region with small lateral and apical spines. Phallotheca small, cone shaped, almost as long as vesical spiculum; aperture open widely on dorsal and right lateral surfaces, narrowed to apex. Vesica small; diameter of spiculum base and body thickened; situated on dorsal surface of ductus seminis, with short basal process; distal region sharply recurved, minutely serrate with sharply pointed apex, length 1/3 of spiculum body.

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, 2.26 (2.27, 2.24–2.30); width, 1.52 (1.48, 1.44–1.52). Head length, 0.20 (0.20, 0.20–0.22); width, 0.80 (0.78, 0.78–0.80); vertex width, 0.38 (0.37, 0.36–0.38). Length of antennal segment I, 0.22 (0.21, 0.20–0.22); II, 0.78 (0.76, 0.74– 0.78); III, 0.56 (0.54, 0.50–0.62); IV, 0.30 (0.30, 0.26–0.32). Pronotal length, 0.60 (0.60, 0.58–0.62); width across base, 1.20 (1.18, 1.16–1.20). Cuneal length, 0.44 (0.47, 0.44– 0.50); width across base, 0.44 (0.46, 0.44– 0.50).

Female (n 5 20; average followed in parentheses by range): Length, 2.53 (2.44– 2.62); width, 1.61 (1.56–1.68). Head length, 0.22 (0.20–0.24); width, 0.82 (0.80–0.84); vertex width, 0.42 (0.40–0.44). Length of antennal segment I, 0.19 (0.16–0.22); II, 0.72 (0.70–0.78), III, 0.58 (0.52–0.62); IV, 0.30 (0.28–0.34). Pronotal length, 0.70 (0.64– 0.74); width across base, 1.27 (1.24–1.32). Cuneal length, 0.47 (0.44–0.52); width across base, 0.45 (0.44–0.50).

DISCUSSION: This species can be distinguished from most others by the reddish or reddish-fuscous coloration on the mandibular plate. The species is relatively ovate; the pronotum and especially the cuneus and wing membrane are relatively declivent, and the outer margin of the corium is strongly curved. The third and fourth antennal segments are subequal in length with the diameter of these segments about the same as first two segments. The cuticular sculpturation is easily visible.

HOST PLANT: Unknown.

00094248); scale 5 0.20 mm.

ETYMOLOGY: Named after the state from which nearly all the specimens were collected.

DISTRIBUTION: Known from two localities in southwestern Michoacan and a single specimen from southern Sinaloa (fig. 10A).
