Ficinus sagittarius Distant   Figures 2, 6–9

Ficinus sagittarius Distant, 1893: 450   (orig. desc.); Carvalho, 1958: 62 (catalog); Carvalho and Dolling, 1976: 806 (disc. of type); Schuh, 1995: 109 (catalog).

DIAGNOSIS: Hemelytron with most of corium, cuneus, and base of clavus dark fuscous to black, remainder of clavus and usually an angulate spot immediately anteri- or to cuneus shining yellowish brown (fig. 2); metepisternum with microtrichia extending well dorsal to evaporative area of scent gland (fig. 6C).

REDESCRIPTION: Male: COLORATION: General body coloration dark fuscous to black with yellow markings. Head black, slightly paler in area of maxillary plate; base of antennal segment I fuscous, remainder yellowish brown sometimes darker apically, remaining segments pale yellowish brown to pale fuscous; labium pale yellowish brown, dark fuscous at apex. Pronotum uniformly black. Scutellum black. Hemelytron with corium including cuneus dark fuscous to black, clavus from apex of scutellum and angulate spot on corium reaching cuneal suture pale yellowish brown; membrane fuscous with distinct clear spotlike area at apex of cuneus. Legs, except for fuscous apices of apical tarsomeres, pale yellowish brown; hind femur of specimens examined from Oaxaca with apical half fuscous. Underside shining, dark fuscous to black, evaporatorium dark fuscous to black. GEN- ITALIA (fig. 7): Genital segment with bifurcate tergal process projecting from region slightly to right of midline on dorsal margin of aperture; medial lobe of process short and pointed, lateral lobe larger and hornlike; ventroposterior margin of capsule not modified, distal width of subgenital plate narrow, slightly projecting beyond aperture of capsule. Left paramere C-shaped in dorsal view; with slightly developed sensory lobe; diameter of paramere gradually expanded distally to wide, flattened mitten-shaped apex. Right paramere longer than left paramere; diameter thick basally and medially, distal region slightly attenuate to large, sinuate bifurcate apex. Phallotheca elongate, cone shaped, 1/2 length of spiculum; aperture convoluted, open on right side, dorsal margin, and apex, right margin with medial point and lateral flange. Vesica with one long, medially thickened spiculum, situated on dorsal surface of ductus seminis; distal region of spiculum bifurcate with recurved, strongly serrate branches almost reaching middle of spiculum; apex of process with S-shaped, somewhat flattened distal region; basal portion of spiculum approximately equal to length of sclerotized portion of ductus seminis.

Female: Similar to male in color and form. GENITALIA (fig. 8); right side of GP8 strongly produced, surrounded by cuplike left side; ventral surface of VLP broadly projecting into VUL; dorsal portion of IRL approximately twice as wide as ventral portion; otherwise as in generic description.

MEASUREMENTS: Male (n 5 20; mean followed in parentheses by range): Length, 4.98 (4.40–5.32); width, 1.27 (1.10–1.44). Head length, 0.22 (0.18–0.26); width through eyes, 0.91 (0.86–0.98); vertex width, 0.46 (0.42–0.48). Length of antennal segment I, 0.40 (0.34–0.44); II, 1.43 (1.28–1.56); III, 1.18 (1.02–1.30); IV, 0.50 (0.40–0.54). Pronotal length, 0.87 (0.82–0.96); width, 1.30 (1.14– 1.44). Cuneal length, 0.78 (0.68–0.82); width, 0.40 (0.34–0.42).

Female (n 5 20; mean followed in parentheses by range): Length, 5.26 (5.04–5.68); width, 1.43 (1.32–1.62). Head width, 0.25 (0.24–0.28); width through eyes, 0.97 (0.94– 1.02); vertex width, 0.52 (0.50–0.54). Length of antennal segment I, 0.41 (0.38–0.44); II, 1.47 (1.40–1.58); III, 1.17 (1.04–1.26); IV, 0.51 (0.44–0.58). Pronotal length, 0.93 (0.88–1.00); width, 1.34 (1.24–1.50). Cuneal length, 0.74 (0.68–0.82); width, 0.41 (0.38– 0.44).

DISCUSSION: The color pattern of this attractive species shows some significant variation on the hind femur. Specimens from the state of Oaxaca have the hind femur with dark fuscous coloration, whereas specimens from Guerrero and Morales have a uniformly pale hind femur. The elongate spot anterior to the cuneus varies in size and is occasionally absent. There is moderate geographical variation in the size of the male genitalia, most easily observed in length of the vesical spiculum and size of the bifurcate serrate apical region. The vesica of specimens from Guerrero is approximately 30% larger than of those from Oaxaca. The lectotype along with three paralectotypes were designated by Carvalho and Dolling (1976). These specimens are deposited in the Natural History Museum, London. Distant (1893) mentioned that his description of F. sagittarius   was based on six specimens; the whereabouts of two of these specimens is currently unknown.

HOST PLANTS: Both adults and nymphs of this species were taken on species of Ipomoea Roem and Schult   ( Convolvulaceae   ). This

small- to medium-sized tree grows commonly along stream beds found in these seasonally arid regions.

DISTRIBUTION: Known from 24 localities in Guerrero, Mexico, Morelos, Oaxaca, and Puebla at altitudes between 1,220 to 1,830 meters (approx. 4,000 to 6,000 feet) (fig. 9).
