DIAGNOSIS: Recognized by relatively small size, head dark fuscous to black but usually with brown coloration near eyes and occasionally across posterior margin of vertex; antennae and body dark fuscous to black, legs yellowish brown (fig. 4); antennal segment II with a few semierect setae slightly longer than diameter of segment; vertex clearly wider than length of antennal segment I; labium short, only reaching procoxa; pronotum smooth and strongly shining, width of pronotum greater than length of antennal segment II; metepisternum dorsal to evaporative area of scent gland with microtrichia. Jornandes xochilapensis is closely related to J. ater as evidenced by the shared tubular process on the medial surface at the base of the right paramere. But J. xochipalensis distinguished by the pale procoxa, whereas in J. ater the coxa is dark. The length of J. xochilapensis is almost a millimeter shorter than J. ater . The two species can also be separated by features of the male genitalia, especially the shape of the distal portion of the vesical spiculum and width of the opening of the distal portion of the left paramere.
DESCRIPTION: Male: COLORATION: Gennerally dark fuscous to black with pale legs. Head dark fuscous to black with areas along eyes and sometimes on posterior margin of vertex brown, area immediately above maxillary plate sometimes fuscous to brown; antenna dark fuscous; labium yellowish brown, apex dark fuscous. Remainder of body dark fuscous to black. Procoxa yellowish brown, meso- and metacoxae fuscous at base, yellowish brown on apical half; femora yellowish brown with a small pale fuscous area near apices; tibiae and tarsi slightly darker in color than femora. VESTI- TURE: Head and pronotum almost devoid of setae, scutellum and corium with scattered
00118201); scale 5 0.20 mm.
decumbent setae usually longer than diameter of antennal segment II; antennal segments II–IV with short decumbent setae and a few semierect setae clearly longer than diameter of respective segments; semierect spines on tibiae slightly longer than diameter of respective tibia; decumbent setae of abdomen longer and more dense. GENITALIA (fig. 37): Genital segment with moderately long, pointed tergal process located on midline of dorsal margin of aperture; ventroposterior margin of capsule with flattened flange, subgenital plate narrow distally, slightly projecting beyond aperture of capsule. Left paramere stoutly C-shaped in dorsal view; sensory lobe broadly produced; diameter of paramere constricted subapically; apex mittenlike, medial process of apex longer than lateral portion. Right paramere stout, similar in size to left paramere; sensory lobe sharply pointed dorsally; diameter of paramere equally thick distal to sensory lobe, terminating in small, dorsally directed apical point; extreme base of paramere with long, narrow, tubelike process reaching to base of sensory lobe. Phallotheca small, cone shaped, as long as 1/2 of vesical spiculum; aperture open widely from dorsal surface to narrowed apex. Vesica small; spiculum sinuate, thickened, and serrate medially with small recurved lobe; base situated on dorsal surface of ductus seminis, without basal process; distal region long, needlelike, length 2/3 of spiculum body.
Female: Color and vestiture as on male.
MEASUREMENTS: Male (n 5 4; those of holotype given first followed in parentheses by average and range): Length, 2.94 (2.79, 2.60–2.94); width, 1.14 (1.16, 1.04–1.16). Head length, 0.28 (0.29, 0.26–0.34); width, 0.66 (0.65, 0.64–0.66); vertex width, 0.34 (0.33, 0.30–0.34). Length of antennal segment I, 0.16 (0.17, 0.16–0.18); II, 0.64 (0.63, 0.58– 0.64); III, 0.54 (0.51, 0.46–0.54); IV, 0.24 (0.23, 0.22–0.24). Pronotal length, 0.52 (0.50, 0.48–0.52); width across base, 1.04 (1.01, 0.94–1.04). Cuneal length, 0.54 (0.51, 0.48– 0.54); width across base, 0.44 (0.41, 0.36– 0.44).
Female (n 5 4; average followed in parentheses by range): Length, 2.52 (2.40– 2.76); width, 1.25 (1.20–1.34). Head length, 0.26 (0.24–0.30); width, 0.64 (0.62–0.66); vertex width, 0.35 (0.34–0.36). Length of antennal segment I, 0.16 (all); II, 0.53 (0.48– 0.58); III, 0.41 (0.38–0.46); IV, 0.24 (0.22– 0.26). Pronotal length, 0.48 (all); width across base, 1.02 (1.00–1.12). Cuneal length, 0.42 (0.38–0.46); width across base, 0.38 (0.36– 0.42).
DISCUSSION: Jornandes xochilapensis is closely related to J. ater and is discussed in more detail there. Characters shared by both species include the body slightly flattened as seen from the side; the head and pronotum are highly polished; antennal segment II has a few long semierect setae; the labium reaching barely beyond the procoxa at most. The cuticular sculpturing on the corium is visible but not as prominent as on most other species of the genus.
HOST PLANT: Unknown.
ETYMOLOGY: Named after the town in the state of Guerrero where this species occurs.
