HOLOTYPE: 3, MEXICO: Guerrero: 10.3 mi S of Iguala [17.70023 ° N 100.36666 ° W], July 23, 1981 Bogar, Schaffner, Friedlander, taken on Mimosa polyantha Benth. , det. Oswald Tellez, 1990 ( AMNH _ PBI 00184925 ). Deposited in the collection of the Instituto de Biología , Universidad Nacional Autónoma de Mexico, Mexico City, D.F.

DIAGNOSIS: Recognized by head brown dorsally, maxillary plate usually dark fuscous, clypeus black, remainder of body and antenna dark fuscous to black, coxa, trochanter, and femur dark fuscous (fig. 3), tibia and tarsomeres frequently paler; 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; and metepisternum dorsal to evaporative area of scent gland with microtrichia. Similar to J. tehuacanensis in the entirely orange-brown head, female with pale medial annulus on antennal segment II; and male genitalia with small right paramere with spinose dorsal lobe, moderately long, Cshaped left paramere with wide apical notch, vesical spiculum bifid, with one long and one short serrate process, and genital aperture without tergal process.

DESCRIPTION: Male: COLORATION: Generally dark shining fuscous to black. Head with brown coloration; vertex, and frons brown, maxillary plate at least on ventral half dark fuscous, clypeus dark fuscous to black, antennal segments dark fuscous to black; labium with basal segment brown, segments II and III fuscous, apical segment dark fuscous to black. Pronotum highly polished dark fuscous to black, remainder of thorax dark fuscous to black. Membrane of hemelytron dark fuscous. Coxa dark fuscous; femora dark fuscous, brown at apex; apical half of tibiae frequently brown; tarsi brown to fuscous. Abdomen dark fuscous. VESTITURE: Head and thorax, except for appendages, almost devoid of setae; scutellum and corium with short and more evenly scattered decumbent setae; membrane of hemelytron usually with scattered decumbent setae; setae of antennal segments II–IV decumbent, about as long as diameter of respective segment; semierect black spines of tibiae longer than diameter of respective tibia; decumbent setae of abdomen long and more dense. GENITALIA (fig. 26): Genital segment without tergal processes, dorsal margin of aperture well-sclerotized, with dense bristlelike setae; 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; sensory lobe minimally produced, denoted by long setae; diameter of paramere wide, gradually expanded to mitten-shaped apex. Right paramere shorter than left paramere, densely covered with long setae; diameter of paramere thick basally; sensory lobe or anterior region with blunt, stoutly spinose tubercle, distal region relatively short, with blunt apex. Phallotheca rectangular, convoluted, equal to 2/3 length of spiculum; aperture small, restricted to crescent-shaped distal opening. Vesica with one moderately long, sinuate, needlelike spiculum, base strongly convoluted, situated on dorsal surface of ductus seminis; narrow distal region serrate; middle of spiculum with narrow spine; base of spiculum wide with small tubercle.

Female: Frons more broadly curved than male and antennal segment II pale medially; otherwise color and vestiture same as for male.

MEASUREMENTS: Male (n 5 20; those of holotype given first followed in parentheses by average and range): Length, 2.90 (2.87, 2.70–3.10); width, 1.38 (1.35, 1.30–1.40). Head length, 0.16 (0.19, 0.16–0.22); width, 0.70 (0.71, 0.68–0.71); vertex width, 0.36 (0.36, 0.36–0.38). Length of antennal segment I, 0.22 (0.21, 0.20–0.24); II, 0.90 (0.89, 0.84–0.92); III, 0.64 (0.66, 0.64–0.70); IV, 0.32 (0.31, 0.30– 0.34). Pronotal length, 0.58 (0.57, 0.52–0.62); width across base, 1.12 (1.08, 1.04–1.16). Cuneal length, 0.54 (0.53, 0.50–0.56); width across base, 0.42 (0.43, 0.40–0.48).

Female (n 5 20; average followed in parentheses by range): Length, 3.04 (2.86– 3.36); width, 1.53 (1.47–1.60): Head length, 0.23 (0.18–0.26); width, 0.75 (0.72–0.76) vertex width, 0.41 (0.40–0.44). Length of antennal segment I, 0.21 (0.18–0.22); II, 0.84 (0.80–0.90); III, 0.62 (0.60–0.68); IV, 0.30 (0.26–0.34). Pronotal length, 0.62 (0.60– 0.66); width across base, 1.16 (1.12–1.20). Cuneal length, 0.52 (0.48–0.52); width across base, 0.52 (0.48–0.56).

DISCUSSION: This species is easily recognized by having most of the body dark fuscous to black except for the brown vertex and frons. The coxa, mesepisternum, and the evaporatorium of the scent gland have pollinose areas consisting of a dense cover of microtrichia. Setae on the membrane of the hemelytra are more common than in most other species. The sculpturing of this species is easily seen on its shining corium and clavus. A number of features of J. mimosae are similar to J. tehuacanensis (see diagnosis).

HOST PLANT: Mimosa polyantha Benth. ( Fabaceae : Mimosoideae ).
