Plagiognathus moerens Reuter, 1909: 80 (n. sp.). Chaetophylidea moerens: Knight, 1968: 33 (n.

comb.).

DIAGNOSIS: Recognized by the medium to large size, linear pattern of coloration with exocorium and clavus mostly opaque, pale, olive­colored, contrasting with dark endocorium (fig. 10), pronotum varying from entirely black to totally pale (olive), antennae entirely black (fig. 17), dorsal vestiture of recumbent, black, bristlelike setae, and surface of dorsum weakly polished (fig. 10). Linear pattern of coloration similar to lineatus (fig. 9) and shoshonea (fig. 13); easily distin­ guished from those species by the black, bristlelike setae on the dorsum and by the distinctive structure of the male genitalia (fig. 28), the vesica lacking a flange and with very long, evenly attenuated apical spines.

REDESCRIPTION: Male: Elongate­ovoid, moderate to large size; total length 3.84– 4.96, length apex clypeus–cuneal fracture 2.81–3.66, width across pronotum 1.23–1.46. COLORATION (fig. 10): Background coloration of dorsum deeply castaneous to blackish with longitudinal, opaque, pale (olive) areas; posterior margin of vertex pale at least at midpoint, sometimes across entire width, posterior lobe of pronotum often pale, costal margin of hemelytra dark or pale, exocorium almost totally pale, clavus pale except narrowly along scutellum and claval commissure, cuneus pale; corium narrowly pale adjacent to extreme base of membrane; membrane fumose, veins demarcating small cell and angle between posterior margin of small cell and posteromesial margin of cuneus pale; antennae entirely castaneous to black (fig. 17); labium castaneous; venter entirely castaneous, metathoracic scent­gland evaporatory area sometimes partially pale; coxae dark, except occasionally pale at articulation with trochanters; trochanters dark; fore­ and middle femora weakly infuscate, hind femur heavily infuscate; tibiae weakly infuscate, hind tibiae sometimes more strongly so, spines of fore and middle tibiae without dark bases, spines of hind tibiae with small dark bases; tibiae dark at articulation with femora. SURFACE AND VESTITURE: Dorsum weakly granular, smooth, moderately shining. Vestiture of dorsum composed of nearly erect, black, bristlelike setae. STRUC­ TURE: Lateral corial margins weakly convex; frons distinctly tumid, clypeus visible from above; anteocular distance 2 times diameter of antennal segment 1; head projecting below eye by about 1.5 times diameter of antennal segment 1; labium reaching slightly beyond apex of hind coxae. GENI­ TALIA (fig. 28): Entire vesica very long, body of vesica relatively stout and strongly curving, more or less J­shaped, base of vesica falling slightly below level of secondary gonopore; apical spines long, of similar length, tapering gradually from gonopore to apex; no flange on vesica.

Female: Body shorter and more strongly ovoid than in male; pronotum and hemelytra more extensively pale than in male. Total length 3.84–4.96, length apex clypeus–cuneal fracture 2.81–3.66, width across pronotum 1.23–1.46.

HOSTS: Amsinckia spp. (Boraginaceae) , Phacelia spp. (Hydrophyllaceae) , and other herbaceous annuals.

DISTRIBUTION: From Idaho and Washington in the north, south through California and into Arizona.

DISCUSSION: Knight (1968) placed moerens Reuter in the new genus Chaetophylidea on the basis of its bristlelike vestiture. The vestiture is a generally variable attribute in Plagiognathus , and the situation in moerens certainly falls within the total range of variation. Because other attributes of moerens , including the male genitalia, fall well within the range of variation seen for the genus as conceived in this paper, I am treating Chaetophylidea as a junior synonym of Plagiognathus .

Plagiognathus monardellae , new species Figures 10 , 17 , 28 HOLOTYPE : Male : ‘‘[ USA] CALIFORNIA: Siskiyou Co. , 6.9 mi S of Medicine Lk. on

Powder Hill Rd., 19 July 1985, collectors GM Stonedahl and JD McIver, ex: Monardella odoratissima (Labiatae) ’’. Deposited in the American Museum of Natural History.

DIAGNOSIS: Recognized by the moderately large size, pale grayish­green coloration (fig. 10), black antennae (17), relatively small eyes, ovoid body form, form of the male genitalia (fig. 28), and the preference for Monardella as the host. Similar in size and coloration of the dorsum to phaceliae (fig. 11), but that species with antennal segment 1 almost entirely pale and the remaining segments at most moderately infuscate (fig. 17). Also possibly confused with flavidus and guttatipes on the coloration of the dorsum, but those species with largely pale antennae.

DESCRIPTION: Male: Moderately large; total length 3.95–4.30, length apex clypeus– cuneal fracture 2.68–2.87, width across pronotum 1.11–1.15. COLORATION (fig. 10): General coloration, including most of venter and appendages, pale gray­green or yellowgreen; membrane weakly fumose, veins pale; antennae black (fig. 17) except for pale apical annulus on segment 1; apex of labium infuscate; thoracic sternum dark; abdominal venter variably infuscate; femora with some dark spots; dorsal tibial spines with small dark spots at bases; tibiae dark at femoral articulation. SURFACE AND VESTITURE: Dorsum weakly granular, smooth, weakly shining. Vestiture of dorsum composed of recumbent, pale, weakly golden, simple setae with some darker suberect setae on pronotum and anterolaterally on hemelytra. STRUC­ TURE: Body ovoid; frons moderately tumid as viewed from above, clypeus visible from above; anteocular distance 1.3 times diameter of antennal segment 1; head projecting below eye by 1.6 times diameter of antennal segment 1; labium reaching to near apex of hind coxae. GENITALIA (fig. 28): Vesica more or less J­shaped, body relatively slen­ der, base falling well below base of secondary gonopore; posterior apical spine elongate, slender, straight, very weakly angled relative to body of vesica, anterior spine smoothly curving and only slightly longer than posterior; flange developed, terminating at level of base of secondary gonopore.

Female: Shorter and more strongly ovoid than male; coloration similar to male. Total length 3.70–3.93, length apex clypeus–cuneal fracture 2.57–2.73, width across pronotum 1.11–1.20.

ETYMOLOGY: Named for its occurrence on Monardella spp.

HOST: Monardella odoratissima (Lamiaceae) .

DISTRIBUTION: Known only from the type locality in Siskiyou County, northern California.
