Figures 1 , 3 , 6–11 , 12

TYPE SPECIES: Crassomiris fatisco , new species.

DIAGNOSIS: Recognized by the small to moderate size (male total length: 2.73–3.21), the orange or orange and whitish coloration with anterior portion of the cuneus transparent, with a triangular area between costal margin and claval suture whitish (fig. 1), the short and stout phallotheca, stout and large Jto C-shaped vesica, and the large and slitlike secondary gonopore (figs. 3, 10). Most similar in coloration and external structure to species of Phallospinophylus , n.gen., Pygovepres , n.gen., Quercophylus , n.gen., Rubellomiris , n.gen., and Rubeospineus , n.gen., but differs from all of these by the combination of male genitalic features.

DESCRIPTION: Male: Macropterous, size rather small to moderate (2.73–3.21), elongate ovoid. COLORATION (fig. 1): General coloration orange or reddish orange and whitish. Head: Head pale orange or pale orange and

whitish; antennal segment 1 yellowish to pale brown, sometimes with subapical and basal ring darker, segment 2 yellowish to pale brown, and segments 3 and 4 pale brown; labial segments 1 to 3 yellowish white to yellow, segment 4 suffused with brown. Thorax: Pronotum either uniformly whitish to pale orange or pale orange and whitish; pleura either rather uniformly pale orange or pale orange with dorsal rim of propleuron and rim of procoxal cavity, dorsal margin of mesepisternum and posterior margin of metepimeron whitish. Legs: Whitish or yellowish with base of coxa slightly infuscate, pale brown spots on femur and tibial spines with dark bases. Hemelytra: Corium including clavus and cuneus mostly pale orange, with proximal area of roughly triangular aspect between R + M or medial fracture and claval suture, basal portion of clavus, and sometimes costal margin whitish, and small white spot at posterior margin of clavus distal to apex; cuneus with proximal crescent-shaped portion whitish; membrane pallid to translucent smoky brown. Abdomen: Venter whitish or orange, often suffused with brown. SURFACE AND VESTITURE: Dorsum weakly shining, covered rather densely with two types of simple, slender, subadpressed setae of moderate length, one type more slender (white asterisk) than other (black asterisk) (fig. 8). STRUCTURE: Head (fig. 3): Subtriangular in dorsal aspect, slightly wider than long, vertex wide, slightly convex and very weakly concave behind, clypeus slightly produced, maxillary plate slightly sunken, buccula short, buccal cavity large and ovoid, gula short; eye more than 3/4 height of head, size moderate, only weakly emarginate posterior to fossa, posterolateral margins contiguous with anterolateral margins of pronotum; antennal insertion contiguous with anterior margin of eye; antennal segment 1 short and slender, only very weakly widened toward apex, segment 2 long, similar in diameter as segment 1, diameter slightly increasing toward apex, segments 3 and 4 with diameter smaller than segments 1 and 2; apex of labium surpassing base of abdomen. Thorax: Pronotum trapeziform, anterior margin slightly sinuate, lateral margins slightly convex, posterior margin slightly concave, anterior and posterior pronotal lobe not demarcated, calli indistinct; metapleural evaporatorium with mushroomlike cuticle area triangular (fig. 6), mushroomlike cuticle around mesothoracic spiracle well developed. Legs: Slender; claws slender, claw hairs present, with pulvilli covering a little more than one-half of ventral claw surface, parempodia setiform (fig. 7). Hemelytra: Costal margins of hemelytra weakly convex, almost subparallel. Abdomen: Stout, reaching to between the middle and the posterior margin of the cuneus, pregenitalic abdomen usually not reaching costal fracture. GENITALIA (figs. 3, 9, 10): Pygophore: Large in comparison with pregenitalic abdomen, broad and short, without ornamentation. Parameres: Right paramere typically phyline (fig. 3), left paramere with anterior process short and knob-shaped, posterior process relatively long and slender and with a number of small holes apically (fig. 9A). Phallotheca: Short and stout (figs. 3, 9B), ventrally with slitlike opening. Vesica: J- to C-shaped, body stout and heavily sclerotized, secondary gonopore subapical, long and narrow, slitlike, gonopore sclerite indistinct, one straight or slightly curved apical blade (figs. 3, 10).

FEMALE: Coloration sometimes somewhat paler than in male, more ovoid body, of about same size as male or slightly larger, antennal segment 2 more slender, increase in diameter toward apex more pronounced than in male. GENITALIA: See description of type species Crassomiris fatisco .

ETYMOLOGY: Named for the solid vesica in the males of this genus, from Latin adjective crassus, meaning ‘‘thick’’, ‘‘dense’’, or ‘‘solid’’, combined with the generic name Miris to emphasize its systematic position within Miridae . The gender of the name is masculine.

DISCUSSION: External features and the rath- er simple, stout vesica in Crassomiris , n.gen., somewhat resemble those in Rubeospineus . However, species of Crassomiris do not have a field of spicules on the body of the vesica, which is diagnostic for Rubeospineus ; the vesica of Crassomiris species is much stouter, the secondary gonopore is distinctly larger and more slitlike, and the gonopore sclerite is indistinct. Furthermore, the stout, short phallotheca and the much shorter vestibulum in dorsal view in the female set Crassomiris species apart from those of Rubeospineus .

HOLOTYPE: Male: USA: California: Tulare Co.: NE of Springville on Bear Creek Rd near Scicon, 36.21394 ° N 118.7716 ° W, 700 m, 23 May 2004, Schuh, Cassis, Schwartz, Weirauch, Wyniger, Forero, Quercus wislizenii A. DC. (Fagaceae) , det. K. Nixon 2004, 13 ( AMNH _PBI 00094810) ( AMNH).

DIAGNOSIS: Distinguished from C. fatisco , n.sp., by the orange or reddish orange and whitish areas not clearly delimited (fig. 1), and the apical spine of vesica in lateral view without subapical ventral notch, but with dorsal indentation, twisted toward the left side, and in caudal view shaped like a duck’s head (fig. 3).

DESCRIPTION: Male: Macropterous, size rather small, elongate ovoid; total length 2.73–2.92, length from apex of clypeus to cuneal fracture 1.90–2.09, width across pronotum 0.89–0.99. COLORATION (fig. 1): General coloration orange to reddish and whitish. Head: Either rather uniformly pale orange or whitish with five paired orange transverse fasciae on vertex and posterior margin of head orange, orange mark on inner rim of eye, paired longitudinal lateral stripes on clypeus, maxillary plate and gena in part including area surrounding antenna orange; antennal segment 1 yellowish, sometimes with very faint subapical and basal ring darker, segment 2 yellowish, and segments 3 and 4 pale brown; labium as in generic description. Thorax: Pronotum including duplicature, mesoscutum, and scutellum rather uniformly dirty whitish to pale orange, sometimes calli with a somewhat darker orange transverse band and sometimes duplicature with submedian patches orange; mesoscutum either uniformly pale orange or pale orange medially and whitish laterally; scutellum either uniformly pale orange or pale orange anteriorly and whitish posteriorly; pleura either rather uniformly pale orange or pale orange with dorsal margin of propleura as well as rim of coxal cavity, dorsal rim of mesepisternum and posterior margin of mesepimeron whitish. Legs: Pale with base of coxa slightly infuscate, pale brown spots on femur, tibial spines with dark bases. Hemelytra: As in generic description. Abdomen: Venter orange, in parts suffused with brown. 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: As in generic description. Vesica: As in generic description, with apex of apical blade strongly turned toward left side and dorsally abruptly narrowed apically, in caudal view shaped like a duck’s head (fig. 3).

FEMALE: As in generic description. Total length 2.81–2.82, length from apex of clypeus to cuneal fracture 1.96–1.97, width across pronotum 0.95–0.96.

ETYMOLOGY: Named for the slightly duckhead-shaped apex of the male vesica in caudal view; from Latin anaticula (fem.), meaning ‘‘little duck’’.

HOSTS: Specimens were recorded from Q. douglasii H. & A. and Quercus wislizeni A. DC.

DISTRIBUTION: Recorded only from California, where the species occurs in the foothills of the Sierra Nevada , in Calaveras, Kern, Madera, Mariposa, and Tulare counties, at elevations ranging between approximately 500 and 1000 meters, with a single specimen recorded as far north and west as Mendocino Co. (fig. 12).

DISCUSSION: The specimens so far recorded imply that the distribution of C. anaticula does not extend as far north as that of C. fatisco (fig. 12). Overlap of ranges of distribution for the two species in the genus Crassomiris occurs in the Sierra Nevada , but here C. anaticula appears to be restricted to the foothills, whereas C. fatisco often occurs in higher elevations. However, in Mariposa Co. , the two species were recorded together from two collecting events in relatively low elevations (around 600 meters), with different hosts at one site ( Q. wislizeni for C. anaticula and Q. douglasii for C. fatisco ), but the same host at the other site ( Q. douglasii ). Nevertheless, the available data seem to imply that C. fatisco is distributed in higher latitudes and altitudes than its close relative C. anaticula . This fact is also reflected by the host range of C. anaticula compared with that of C. fatisco . Crassomiris anaticula is known from Q. douglasii and Q. wislizenii , both of which occur on the lower slopes (below approx. 1500 meters) of the Sierra Nevada and the inner Coast Ranges ( Munz & Keck 1959), whereas C. fatisco occurs on, apart from Q. douglasii , Q. garryana and Q. kellogii , both of which occur in higher altitudes and latitudes (fig. 12).

Crassomiris anaticula may occur sympatrically with other orange oak bugs. At one locality (NE of Springville on Bear Creek Rd, Tulare Co.), C. anaticula and Phallospinophylus setosus were recorded from the same host, Quercus wislizenii , and from another locality (Mokelumne Hill, Calaveras Co.) the two species were recorded from two collecting events that were a week apart. Crassomiris anaticula is sympatric with Pygovepres vaccinicola at all its localities from Mariposa Co. , some in Tulare Co., and one in Kern Co., where the two species were sometimes collected from the same species of Quercus .

In Madera and Mariposa counties, California, C. anaticula may occur sympatrically with the very similar, but slightly smaller Rubellomiris mariposa , n.sp. Specimens examined during this project were collected on the same date on the same host ( Q. douglasii ). Crassomiris anaticula is also recorded from the same locality as R. truncatus , in Calaveras Co., however, from different collecting events.

ETYMOLOGY: Named for the bottle-opener shape of the apex of the male vesica; first person singular, from Latin verb fatiscere, meaning ‘‘to open,’’ used as an apposition.

HOSTS: Recorded mainly from Quercus douglasii H. & A., Q. garryana Dougl. , and Q. kellogii Newb. , with some specimens collected on Cercocarpus and Purshia .

DISTRIBUTION: Recorded from Oregon (Benton, Douglas, Jackson, and Josephine counties) and the northern counties of California (Humboldt, Lassen, Modoc, Shasta, Trinity), but also extends south to Kern Co. along the Sierra Nevada , mainly at higher elevations (fig. 12).

DISCUSSION: See C. anaticula for discussion of the range of distribution and hosts of the two species in the genus Crassomiris . Crassomiris fatisco was collected at the same localities as Pygovepres vaccinicola (Knight) in numerous places in Oregon and Lassen and Mariposa counties in California. Crassomiris fatisco also occurs sympatrically with Rubellomiris mariposa , n.sp., in Mariposa Co. , where the two species were collected on Q. douglasii .
