description: <i>Jornandes rileyi</i>, new species Figures 3, 10A, 30 HOLOTYPE: &amp;female;, MEXICO: <b>Baja California Sur:</b> 14.4 mi E on Ramal a Los Naranjo [23.25661 <i>°</i> N 109.91648 <i>°</i> W, 1101 m], IX-16- 88, E. G. Riley, black light (AMNH _ PBI 00184928). Department of Entomology, Texas A &amp; M University, College Station, Texas. DIAGNOSIS: Recognized by body, including antennae and legs, shining reddish fuscous to black except for pale band extending across posterior margin of pronotum (fig. 3); frons rounded; vertex clearly wider than length of antennal segment I; labium reaching mesocoxa or slightly beyond; width of pronotum greater than length of antennal segment II; robust with costal margins of hemelytron curved; metepisternum dorsal to evaporative area of scent gland with microtrichia. DESCRIPTION: <i>Male</i>: COLORATION: Generally dark reddish fuscous to black with posterior margin of pronotum almost white. Corium appearing brown in translucent areas but dark fuscous or black as seen from side. Underside, antennae, labium, and legs reddish fuscous to black. VESTITURE: Head, pronotum, and corium shining with widely scattered, short, inconspicuous, darkcolored setae; setae on antennal segments II– IV semierect and not significantly longer than diameter of respective segments; decumbent setae on underside of abdomen denser and longer. GENITALIA (fig. 30): <b>Genital segment</b> with single small, pointed tergal process projecting from midline of dorsal margin of aperture; ventroposterior margin of capsule flangelike with medial cleft, distal width of subgenital plate narrow, projecting strongly dorsal to aperture of capsule. <b>Left paramere</b> C-shaped in dorsal view; without sensory lobe; diameter of paramere gradually expanded distally to mittenlike apex. <b>Right paramere</b> larger than left paramere; with long, narrow, strongly attenuate sensory lobe and paramere body, apices minutely serrate. <b>Phallotheca</b> elongate, cone shaped, equal to length of spiculum; aperture wide, open on right side, dorsal margin, and apex. <b>Vesica</b> with one long, medially thickened spiculum, situated on dorsal surface of ductus seminis; apical region of spiculum recurved, attenuate, strongly serrate, distal region almost 1/3 length of spiculum; base of spiculum with large process reaching to 1/2 length of main body of spiculum more distal to smaller flattened rectangular basal process. <i>Females</i>: Slightly larger than males; color and vestiture as for male. MEASUREMENTS: <i>Male</i> (n 5 2): Length, 2.40 and 2.70; width, 1.30 and 1.56. Head length, 0.24 and 0.26; width, 0.72 and 0.80; vertex width, 0.36 and 0.38. Length of antennal segment I, 0.24 (remaining segments missing). Pronotal length, 0.56 and 0.68; width across base, 1.10 and 1.30. Cuneal length, 0.48 and 0.52; width across base, 0.48 and 0.50. (AMNH_PBI 00118211); scale 5 0.20 mm. <i>Female</i> (n 5 4; those of holotype given first followed in parentheses by average and range): Length, 2.64 (2.74, 2.64–2.80); width, 1.80 (all). Head length, 0.24 (0.24, 0.20–0.25); width; 0.84 (0.83, 0.80–0.84); vertex width, 0.42 (0.42, 0.40–0.42). Length of antennal segment I, 0.28 (0.24, 0.22–0.28); II, 0.84 (single paratype, 0.80); III, 0.54 (holotype only); IV, missing. Pronotal length 0.80 (0.76, 0.64–0.80); width across base, 1.36 (1.34, 1.30–1.38). Cuneal length, 0.54, 0.54, 0.50– 0.58); width across base, 0.50 (0.50, 0.48– 0.50). DISCUSSION: The unique color pattern distinguishes this species from all others of the genus. The reddish fuscous to black pronotum has a whitish broad band along the posterior margin. Curiously, the same distinctive color pattern is exhibited by some specimens of <i>Scalponotatus albibasis</i> (Knight), which occurs in southwestern U. S. and northwestern Mexico. The typical <i>Jornandes</i> type of sculpturing is easily seen, whereas <i>S</i>. <i>albibasis</i> has a roughened dorsum. All specimens were collected into alcohol at light. No setae were present on the hemelytral membrane. This is the only known species of <i>Jornandes</i> occurring in Baja California Sur. A female was selected as holotype because it was better preserved than any of the three available males. HOST PLANT: Unknown. ETYMOLOGY: Named for E. G. Riley from Texas A&amp;M University who collected all the specimens of this species. DISTRIBUTION: Known only from the type series from Baja California Sur (fig. 10A).

Riley, black light, 1&amp;female; (AMNH_ PBI 00119110), 13 (AMNH_PBI 00118211) (CNC). 13 (AMNH_PBI 00094301), 1&amp;female; (AMNH_PBI 00094302), 13 (AMNH_PBI 00184787), 2&amp;female; (AMNH_PBI 00184788, AMNH_ PBI 00184789) (TAMU).
