TYPE SPECIES: Rubeospineus truncatus   , new species.

DIAGNOSIS: Recognized by the small to moderate size (male total length: 2.30–3.34), pale orange and whitish coloration with anterior portion of the cuneus transparent, relatively short and stout J-shaped vesica (figs. 5, 10) with a field of small spicules dorsally on the left side of the vesical body, and a reticulate cuticular pattern on the relatively slender phallotheca (figs. 5, 9I). Similar in external features and coloration to Crassomiris   , Phallospinophylus   , Pygovepres   , Quercophylus   , and Rubellomiris   . Distinguished from all of them by the structure of the male vesica. The somewhat similar vesica in Crassomiris   with larger and more slitlike secondary gonopore, without spicules on the vesical body, and with the phallotheca shorter and stouter. Distinguished from Phallospinophylus   and Pygovepres   by lacking a patch of stout setae or a spiniferous process anterior to the genital opening on the left side of the pygophore.

DESCRIPTION: Male: Macropterous, size small to moderate (2.30–3.34), moderately elongate ovate. COLORATION (fig. 2): General coloration pale orange and whitish to pale reddish brown or yellowish. Head: Head whitish and orange or yellow to pale red, with five pale orange or brown paired transverse fasciae on vertex, clypeus often with brown paired lateral longitudinal stripes, mandibular and maxillary plates whitish or orange, buccula whitish; antennal segments 1 to 4 yellowish, sometimes with faint dark ring basally or/and subapically on segment 1; labial segments 1 to 3 yellowish, segment 4 suffused with brown. Thorax: Pronotum whitish, calli with transverse, laterally recurving pale orange band, posterior pronotal lobe often with large, paired, pale orange marks, mesoscutum pale orange with lateral margins whitish, scutellum pale orange proximally, distal and lateral portion whitish; pleura pale orange to brownish, with the margins of the pro- and mesocoxal cavities, the dorsal margin of the propleuron, and dorsal and posterior margin of mesopleuron lighter or whitish, evaporatorium often brownish. Legs: Whitish, base of fore coxa and to lesser degree of middle and hind coxa suffused with pale brown, femur distally with dark spots on anterior and posterior face, tibial spines with dark bases. Hemelytra: Corium including clavus and cuneus pale orange, corium proximally, often also on anterior rim, and area between vein R+M and medial fracture, small spot at posterior margin distal to apex of clavus whitish, cuneus with proximal crescent-shaped area whitish transparent, membrane translucent and slightly smoky. Abdomen: Venter yellowish white and orange with large areas suffused with pale brown. SURFACE AND VESTITURE: Dorsum and hemelytra weakly shining, covered rather densely with two types of long, slender, subadpressed setae, two types only differing slightly in their diameter (fig. 8F: black vs. white asterisks designate sockets of setal types). STRUCTURE: Head (fig. 5): Subtriangular in dorsal aspect, vertex wide, slightly convex and very weakly concave behind, clypeus slightly produced, mandibular plate not produced, maxillary plate sunken, buccal cavity large and ovoid, gula broad; eyes almost as high as head, only weakly emarginate posterior of antennal fossa, posterolateral margins contiguous with anterolateral margins of pronotum; antennal insertion contiguous with anterior margin of eye; antennal segment 1 short, segment 2 long, diameter similar to segment 1, very slightly increasing toward apex, segments 3 and 4 with diameter smaller than segments 1 and 2; apex of labium surpassing base of hind coxa. Thorax: Pronotum trapeziform, anterior margin slightly sinuate, lateral margins slightly convex, posterior margin slightly concave, anterior and posterior pronotal lobes weakly demarcated, calli weakly developed; metapleural evaporatorium as in fig. 6F. Legs: Slender, claws weakly curved, claw hairs present, parempodia setiform, pulvilli covering a little less than half of ventral claw surface (fig. 7F). Hemelytra: Subparallel, cuneus elongate triangular. Abdomen: Reaching to about apex of cuneus, pregenitalic abdomen to about costal fracture. GENITALIA (figs. 5, 9I, 10): Pygophore: Relatively large and broad, without ornamentation. Parameres: Right and left parameres typically phyline, right paramere with a pointed tip, left paramere with anterior process slightly shorter than posterior process and rather stout, body with setae on distinct tubercles and microchetae interspersed between setae (figs. 5, 9I). Phallotheca: Typically phyline, with apex moderately long and slender, cuticle of posterior side showing faint longitudinal ridges, anterior side a reticulate pattern (fig. 9I), ventrally with slitlike opening; Vesica: Relatively stout, J-shaped or slightly S-shaped, with a field of small spicules dorsally on left side of vesical body (fig. 10), secondary gonopore in subapical position, elongate opening of moderate size, facing left and fringed with a membranous lobe, gonopore sclerite present, slender, straight and elongate, vesical apex comprising either only a simple well-sclerotized spinous process or an additional proximal spine (fig. 5).

FEMALE (fig. 2): Coloration as in male or slightly paler, shape and size similar to male, or slightly larger and stouter, antennal segment 2 more slender, increase in diameter toward apex more pronounced than in male. GENITALIA: See description of type species, R. truncatus   .

ETYMOLOGY: Named for the orange-red general coloration from Latin verb rubere meaning ‘‘to be red, to blush’’, and the diagnostic field of spicules on the left side of the body of the vesica, after the Latin adjective spineus, meaning ‘‘of thorns’’, ‘‘thorny’’. The gender of the name is masculine.

DISCUSSION: A field of small spicules dorsally on the left side of the vesical body, one of the diagnostic features of Rubeospineus   , to my knowledge, has not been described elsewhere among North American Phylini   . This feature appears to represent an apomorphic character of this taxon.

HOLOTYPE: Male: USA: California: Santa Barbara Co.   : Upper Oso Campground off Rt 154, 34.55583 ° N 119.75389 ° W, 305 m, 7 May 1985, R. T. Schuh and B. M. Massie, Quercus agrifolia oxyadenia   ( Fagaceae   ), det. K. Nixon 1985, 13 ( AMNH _PBI 00060482) ( AMNH).

DIAGNOSIS: Recognized by the slightly Sshaped vesica, with small exterior spine in addition to the long acute interior blade (fig. 5). Distinguished from R. truncatus   and R. yosemite   also by the more contrasting reddish-orange and whitish color pattern, with the posterior pronotal lobe usually largely whitish.

DESCRIPTION: Male: Moderately elongate ovate; total length 2.30–3.17, length from apex of clypeus to cuneal fracture 1.35–2.26, width across pronotum 0.94–0.97. COLOR- ATION (fig. 2): General coloration pale reddish brown to pale orange. Head: Head pale yellowish or pale red, vertex often with five brown paired transverse fasciae and one additional brown mark at anterior rim of eye, clypeus often with lateral longitudinal stripes and apex brown, mandibular plate and buccula whitish; antennal segments 1 to 4 pale yellowish brown with base of first segment suffused with brown; labial segments as in generic description. Thorax: Pronotum whitish, with area of callus with transverse laterally recurving pale orange band, posterior pronotal lobe whitish with only faint paired paramedian pale orange marks, mesoscutum and scutellum as in generic description; pleura including evaporatory area largely dirty orange or suffused brownish, with margins of cavities of the pro- and mesocoxa, as well as dorsal margin of propleuron, and dorsal and posterior margins of mesopleuron somewhat lighter. Legs: As in generic description with tibia proximally pale. Hemelytra: As in generic description, with corium including clavus pale orange, reddish or pale brown with area between vein R+M and medial fracture often transparent, and with area between medial fracture and claval suture often whitish proximally. Abdomen: As in generic description. SURFACE AND VESTITURE: As in generic description. STRUCTURE: Head: Head including eyes, antennae, and labium as in generic description. Thorax: Thorax including legs and hemelytra as in generic description. Abdomen: As in generic description. GENITALIA: Pygophore, Parameres, and Phallotheca (fig. 5): As in generic description. Vesica: As in generic description, with small sclerotized exterior blade in addition to long interior blade also present in R. truncatus   and R. yosemite   .

FEMALE: As in generic description, shape and size similar to male, coloration as in male. Total length 2.66–3.20, length from apex of clypeus to cuneal fracture 1.79–2.26, width across pronotum 0.84–1.07.

ETYMOLOGY: Named for the two apical blades of the male vesica, from the Latin adjective bicorniger   (masc.), meaning ‘‘with two horns’’.

HOSTS: Recorded mainly from Quercus agrifolia Née   and Q. chrysolepis Liebm.   ( Fagaceae   ).

DISTRIBUTION: Occurs in Baja California Norte , Mexico, and in California in the United States. In California, the distribution ranges from the central Sierra Nevada   in Alpine and Tuolumne Counties to the Cleveland National Forest in San Diego Co., but extends also along the coast into the Los Padres National Forest in Ventura County (fig. 13)   .

DISCUSSION: Among the three species of Rubeospineus   , R. bicorniger   shows the most southern distribution, with the majority of records from the mountain ranges in San Diego and Riverside counties. Rubeospineus truncatus   is largely confined to the Coast Range north of San Luis Obispo County, with its northern limit extending to Oregon. Both species, however, have two records from the foothills of either the southern or central Sierra Nevada   , which may indicate that the two species are not entirely restricted to areas adjacent to the coast. The third species, R. yosemite   , is only known from Yosemite National Park.

It is interesting that the two species of Rubeospineus   for which host records are available, R. bicorniger   and R. truncatus   , use the same species of oaks as hosts, Quercus agrifolia   and Q. chrysolepis   . However, in the northern parts of its distribution, R. truncatus   was also collected on Lithocarpus densiflorus   ( Fagaceae   ) (fig. 13).

See discussions of Phallospinophylus setosus   and Pygovepres vaccinicola   n. comb. for comment on sympatrical occurrence of R. bicorniger   with these species. Rubeospineus bicorniger   is also sympatric with Q. gonoporospinus   in the ‘‘Green River Camp’’ area of Orange County.

HOLOTYPE: Male: USA: California: Del Norte Co.: 38 miles NE of Crescent City, 41.99003 ° N 123.72165 ° W, 560 m, 10 Jul 1979, R. T. and Joe Schuh, Lithocarpus densiflorus   ( Fagaceae   ), 13 ( AMNH _PBI 00059972) ( AMNH).

DIAGNOSIS: Recognized by the large, stout, J-shaped vesica with only one apical blade, with its apex truncate in caudal view (fig. 5). Also distinguished from R. yosemite   by the longer and stouter apical blade. Further distinguished from R. bicorniger   by the more uniformly orange coloration.

DESCRIPTION: Male: Moderately elongate ovate; total length 2.90–3.34, length from apex of clypeus to cuneal fracture 2.07–2.37, width across pronotum 0.98–1.19. COLORATION (fig. 2): General coloration pale orange and whitish. Head: Vertex whitish with five pale orange paired transverse fasciae, clypeus whitish with paired lateral longitudinal stripes, mandibular and maxillary plate whitish, buccula whitish; antennal segments 1 to 4 yellowish, often with faint dark rings basally and subapically on segment 1; labium as in generic description. Thorax: Pronotum whitish, calli with transverse laterally recurving pale orange band, posterior pronotal lobe often with large paired pale orange marks, mesoscutum and scutellum as in generic description; pleura pale orange to brownish, with margins of pro- and mesocoxal cavities, dorsal margin of propleuron, and dorsal and posterior margin of mesopleuron whitish, evaporatorium brownish. Legs: As in generic description with tibia proximally often suffused with brown. Hemelytra: As in generic description, with corium including clavus pale orange, anterior rim of corium proximally whitish, area between vein R+M and medial fracture often transparent. Abdomen: As in generic description. SURFACE AND VESTITURE: As in generic description (fig. 8F). STRUCTURE: Head including eyes, antennae, and labium as well as thorax and abdomen as in generic description; metapleural evaporatorium with peritreme large and area of mushroomlike cuticle as in fig. 6F, mushroomlike cuticle around mesothoracic spiracle weakly developed; legs slen- der, claws slender with pulvilli covering a little less then half of their ventral surface, parempodia setiform (fig. 7F). GENITALIA: Pygophore, Parameres, and Phallotheca: As in generic description (fig. 5, 9I, 10). Vesica: Jshaped, with only one slender apical blade, with apex truncate and slightly widened in caudal view.

FEMALE: As in generic description, somewhat larger and stouter than male, coloration paler than male. Total length 3.08–3.60, length from apex of clypeus to cuneal fracture 2.21– 2.43, width across pronotum 1.01–1.16. GENITALIA: Vestibulum slender and elongate, weakly curved, bursa colupatrix of medium seize, posterior margin with sloping indentation, sclerotized rings of medium size, slender (fig. 11).

ETYMOLOGY: Named for the blunt apex of the male vesica, from the Latin adjective truncatus   (masc.), meaning ‘‘cut off at the tip’’.

HOSTS: Collected mainly on Quercus agrifolia Née   , Q. chrysolepis Liebm.   , and Lithocarpus densiflora (Hook & Arn.)   ( Fagaceae   ).

DISTRIBUTION: Recorded from the Coast Range in California and Oregon, with one record each from Cleveland National Forest (San Diego Co.), the southern foothills of the Sierra Nevada (Kern Co.)   , and the foothills of the central Sierra Nevada (Calaveras Co.)   (fig. 13).

DISCUSSION: This species seems to be very close to R. yosemite   , but can be distinguished by the characters pointed out in the diagnosis.

Refer to discussion for R. bicorniger   , n.sp., or comments on distribution and host range relative to the other species in Rubeospineus   . Rubeospineus truncatus   was found at the same locality as Crassomiris anaticula   in Calaveras County, however, during different collecting events, and was collected together with Pygovepres vaccinicola   , n. comb.

Rubeospineus yosemite   , new species

Figures 2, 5, 13

HOLOTYPE: Male: USA: California: Mariposa Co.   : Yosemite National Park , 37.85 ° N 119.56667 ° W, 1201 m, 17 Jun 1928, E. O. Essig, 13 ( AMNH _ PBI 00079624 View Materials ) ( UCB). GoogleMaps  

DIAGNOSIS: Recognized by the slightly Sshaped vesica with only one apical blade, its apex pointed in caudal view (fig. 5). Vesica smaller than in R. truncatus   , its apex shorter and more slender. Further distinguished from R. bicorniger   by the more uniformly orange coloration.

DESCRIPTION: Male: Moderately elongate ovate; total length 2.98, length from apex of clypeus to cuneal fracture 2.10, width across pronotum 0.99. COLORATION (fig. 2): General coloration pale orange and whitish. Head: Vertex whitish with five pale orange paired transverse fasciae and mark on inner margin of eye, clypeus whitish with paired lateral longitudinal stripes and mark at base orange, mandibular plate whitish, maxillary plate and area surrounding antennal base orange, buccula whitish; antennal segments 1 to 4 yellowish, with faint dark subapical ring on segment 1; labial segments 1 and 2 yellowish, 3 and 4 hidden. Thorax: Pronotum whitish, with area of callus with faint orange transverse band, duplicature with large submedian pale orange marks, mesoscutum and scutellum as in generic description; pleura largely pale orange, with margins of cavities of pro- and mesocoxa, dorsal margin of propleuron, and dorsal and posterior margins of mesopleuron whitish, evaporatorium hidden. Legs: Whitish, base of forecoxa and to a lesser degree of middle and hind coxa suffused with pale brown, femur distally with dark spots on anterior and posterior face, tibia proximally pale. Hemelytra: As in generic description, with corium including clavus pale orange, anterior rim of corium proximally whitish. Abdomen: As in generic description. SURFACE AND VESTITURE: As in generic description. STRUCTURE: Head: Head including eyes, antennae, and labium as in generic description. Thorax: Thorax including legs and hemelytra as in generic description. Abdomen: As in generic description. GENITALIA (fig. 5): Pygophore, Parameres, and Phallotheca: As in generic description. Vesica: As in generic description, with only one rather short and slender apical blade, apex acute in caudal view, body of vesica slightly Sshaped and of moderate size.

FEMALE: Unknown.

ETYMOLOGY: Named for the type locality, Yosemite National Park   .

HOSTS: Unknown.

DISTRIBUTION: Only known from Yosemite National Park (fig. 13).

DISCUSSION: Only a single male is known for this species, which in external features appears to be indistinguishable from R. truncatus   . Given the very limited intraspecific variability of the vesica in R. truncatus   —all vesicae examined are J-shaped, rather stout, with a long and stout apical blade that is truncate in caudal view—the vesical characters described here for R. yosemite   justify the treatment of this unique specimen as the representative of a species distinct from R. truncatus   .
