HOLOTYPE: 3, MEXICO: Puebla: 4 mi W of Acatepec [19.03332 ° N 98.34485 ° W], July 26, 1973, Mastro & Schaffner ( AMNH _ PBI 00184929 View Materials ). Deposited in the collection of the Instituto de Biología , Universidad Nacional Autónoma de Mexico, Mexico City, D.F. GoogleMaps

DIAGNOSIS: Recognized by head pale yellowish brown to brown with maxillary plate, sometimes mandibular plate, and clypeus dark fuscous, antennal segments variable in color, pronotum yellowish brown with posterior margin usually paler, hemelytron dark fuscous to black with extreme base usually more or less yellowish brown, femora dark fuscous except at extreme apices, tibiae pale, hind tibiae fuscous at base (fig. 3); vertex clearly wider than length of antennal segment I; labium not reaching posterior margin of mesocoxa; width of pronotum greater than length of antennal segment II; metepisternum dorsal to evaporative area of scent gland with microtrichia. The overall color pattern is similar to that of J. genetivus , J. tehuacanensis , and J. nathani , although J. robustus is larger than the other species.

DESCRIPTION: Male: COLORATION: Generally yellowish brown and dark fuscous to black. Head pale yellowish brown to brown with maxillary plate, sometimes mandibular plate, and clypeus dark fuscous; antennal coloration rarely all dark fuscous, more frequently with segment I pale with fuscous areas at base and or apex, segment II often pale at base, fuscous apically; labium with segments I and basal part of II dark fuscous, segment IV dark fuscous to black. Pronotum yellowish brown, posterior margin of dorsum usually paler, lateral margin often with reddish tinge or reddish narrow line. Mesoscutum, scutellum, hemelytron, and abdomen dark fuscous to black, xyphus pale fuscous. Propleuron adjacent to coxa pale fuscous, dorsal area of mesopleuron yellowish brown, remainder of mesopleuron and mesosternum dark fuscous; metapleuron yellowish brown with pale fuscous areas, evaporatorium pale fuscous. Coxa and trochanter pale fuscous, femur dark fuscous often pale at juncture with tibiae, tibiae and basal tarsomeres pale, base of hind tibia and remaining tarsomeres dark fuscous. VESTI- TURE: Head and thorax, except for appendages, almost devoid of setae, corium with scattered short inconspicuous setae with longer setae on embolium; setae on antennal segments II–IV decumbent, not longer than diameter of respective segment; semierect setae of tibiae as long or slightly longer than respective tibia; decumbent setae of abdomen long and more dense. GENITALIA (fig. 31): Genital segment with bifurcate tergal process projecting from right side of midline of dorsal margin of aperture; main portion of process with short dorsal spine and long curved ventral spine reaching into aperture, base of process with two tubercles on dorsal surface of capsule; ventroposterior margin of capsule cleft; subgenital plate prominent, strongly protruding distally beyond aperture of capsule. Left paramere C-shaped in dorsal view; with broad, tumid sensory lobe; diameter of paramere wide, gradually expanded to mitten-shaped apex. Right paramere large, just twice as long as left paramere; diameter of paramere gradually thickened from base to medial region, shaft distal to middle, 1/2 as long as entire length of paramere, with strong spines on medial surface and pointed apex. Phallotheca cone shaped, 1/2 length of spiculum; aperture convoluted, open on right side with deep ventral notch and on dorsal margin, apex, and right margin. Vesica with one long, sinuate, needlelike spiculum, base situated on dorsal surface of ductus seminis; medial region of spiculum with several spinules; base of spiculum with short, flattened, truncate process.

Female: Antennal segment II usually dark fuscous apically, otherwise color and vestiture same as for male; lateral margin of pronotum less likely to have reddish tinge or line.

MEASUREMENTS: Male (n 5 8; those of holotype given first followed in parentheses by average and range): Length, 4.30 (4.29, 4.02–4.54); width, 2.00 (2.04, 1.94–2.12). Head length, 0.22 (0.22, 0.18–0.24; width, 0.98 (0.97, 0.94–0.98); vertex width, 0.42 (0.41, 0.40–0.42). Length of antennal segment I, 0.32 (0.30, 0.28–0.32); II, 1.26 (1.22, 1.12– 1.28); III, 0.94 (0.84, 0.72–0.94); IV, 0.42 (0.43, 0.42–0.44). Pronotal length, 0.74 (0.76, 0.72–0.82); width across base, 1.50 (1.49, 1.46–1.50). Cuneal length, 0.84 (0.82, 0.78– 0.86); width across base, 0.70 (0.70, 0.68– 0.72).

Female (n 5 9; average given first followed in parentheses by range): Length, 4.06 (3.70– 4.28); width, 2.06 (1.96–2.18). Head length 0.27 (0.24–0.30); width, 1.00 (0.98–1.04); vertex width, 0.47 (0.44–0.48). Length of antennal segment I, 0.28 (0.26–0.30); II, 1.20 (1.14–1.24); III, 0.79 (0.74–0.84); IV, 0.42 (0.36–0.46). Pronotal length, 0.80 (0.76– 0.82); width across base, 1.55 (1.48–1.62). Cuneal length, 0.68 (0.66–0.72); width across base, 0.74 (0.70–0.80).

DISCUSSION: The setae on the dorsum are sparse, short, and inconspicious except in the cuneal area of the corium. The hemelytral membrane is devoid of setae. Specimens are strongly shining and the sculpturing is easily seen. The maxillary plate is dark fuscous as is the case of many species of the genus; however, the band stretching over the maxillary plates and clypeus is sometimes obscured by the darker coloration on the mandibular plate and surrounding areas. Jornandes robustus is similar to J. rachelleae . The posterior margin of the mesepimeron and anterior area of metepisternum are yellowish brown, whereas these areas are fuscous to black in J. rachelleae .

HOST PLANT: Unknown.

ETYMOLOGY: Named for its relatively robust appearance.

DISTRIBUTION: Known from four localities in western Puebla near the border with Oaxaca and central Oaxaca (fig. 10B).

Jornandes sinaloa (Carvalho) , new combination Figures 3, 10A, 32

Rhinocapsidea sinaloa Carvalho, 1987: 232 , figs. 23–26 (orig. desc.); Schuh, 1995: 192 (catalog).

DIAGNOSIS: Recognized by uniform pale yellowish brown coloration over entire body except eyes; dorsum practically glabrous; vertex width greater than length of antennal segment I; labium not reaching mesocoxa; width of pronotum greater than length of antennal segment II; metepisternum dorsal to evaporative area of scent gland with microtrichia. Similar to J. cruralis and J. genetivus in the large body, parallel-sided costal margins, vesical spiculum with bifurcated terminal branches, long right paramere, and mostly spinose tergal processes (in J. cruralis ).

REDESCRIPTION: Male: COLORATION: Generally pale yellowish brown with areas on veins and apices of tarsi fuscous. Membrane as pale as remainder of hemelytron (fig. 3). VESTITURE: Sparse, short, suberect setae. Head and thorax, except appendages with short setae; scutellum and hemelytron almost devoid of setae, setae most easily observed on embolium and near anterior portion of clavus suture; antenna segment I pale, lacking subapical fuscous ring; semierect setae on tibiae about as long as diameter of respective tibia; decumbent setae of abdomen long and more dense. GENITALIA (fig. 32): Genital segment with short, spinose tergal process projecting from right side of midline of dorsal margin of aperture; ventroposterior margin of capsule with smooth notch, subgenital plate deep, not projecting beyond aperture of capsule. Left paramere C-shaped in dorsal view; sensory lobe not produced, diameter of paramere wide, gradually ex-

5 0.20 mm.

panded to wide mitten-shaped apex. Right paramere twice as long as left paramere; diameter of paramere thick basally and medially, distal region curved dorsally, spinose, attenuate to pointed apex. Phallotheca small, cone shaped, 2/3 length of spiculum; aperture ovoid, open at apex. Vesica small; spiculum stout, moderately sinuate, trunklike, base situated widely on dorsal surface of ductus seminis; distal region with narrow, bifurcate, recurved, serrate branches, longest branch reaching to about middle of spiculum; base of spiculum with small, narrow, pointed process behind ductus seminis on left side.

Female: Frons more broadly curved and body wider than male; otherwise color and vestiture same as for male.

MEASUREMENTS: Male: (n 5 3; average and range): Length, 3.83 (3.55–4.08); width, 1.48 (1.43–1.50). Head length, 0.24 (0.24–0.25); width, 0.90 (0.88–0.92); vertex width, 0.40 (0.39–0.40). Length of antennal segment I, 0.36 (all), II 1.20 (n 5 1), remaining segments of all specimens missing. Pronotal length, 0.74 (0.71–0.76); width across base, 1.24 (1.20–1.28). Cuneal length, 0.61 (0.56–0.64); width across base, 0.47 (0.45–0.50).

Female: (n 5 2; average and range): Length, 4.10 (4.00–4.20); width, 1.78 (1.70– 1.85). Head length, 0.29 (0.28–0.29); width, 0.91 (0.90–0.91); vertex width, 0.45 (0.44– 0.46). Length of antennal segment I, 0.36 (0.35–0.36); II, 1.31 (1.28–1.33); III, 0.88; IV, 0.38. Pronotal length, 0.79 (0.78–0.80); width across base, 1.38 (both). Cuneal length, 0.60 (0.59–0.60); width across base, 0.51 (0.50– 0.51).

DISCUSSION: Carvalho (1987) described this species based on four females and 39 males; we have examined the paratypes listed below. Although all features of the male genitalia are of similar form in J. sinaloa , J. cruralis , and J. genetivus , the uniform pale yellowish-brown coloration distinguishes J. sinaloa from its congeners. More closely related to J. cruralis than to J. genetivus by virtue of the serrate tergal process and dorsally projecting distal portion of the right paramere. Jornandes sinaloa has a small spine on the left side of the basal margin of the vesical spiculum, J. cruralis lacks this spine.

HOST PLANT: Unknown.

DISTRIBUTION: Known from two localities in southern Sinaloa and Sonora (fig. 10A).
