DIAGNOSIS: Recognized by the
large
size,
pale grayishgreen coloration
(fig. 11), the largely
pale antennal segment 1 and dark antennal segment 2
(fig. 18), the vesica with relatively short apical spines and no flange (fig. 30), and the preference for
Phacelia
as the host. Similar in size and coloration of the dorsum to
monardellae
(fig. 10), but that species with all antennal segments entirely black.
DESCRIPTION:
Male:
Large, elongate, rela tively slender; total length 4.75–5.05, length apex clypeus–cuneal fracture 3.19 –3.46, width across pronotum 1.03–1.40. COLOR ATION (fig. 11): General coloration, including most of venter and appendages, pale graygreen; membrane at most very weakly fumose, veins pale; antennal segment 1 always dark on tapered basal portion, remain der of segment lighter in color and with a pale apical annulus, segments 2, 3, and 4 castaneous (fig. 18); labium weakly infuscate; thoracic sternum dark; thoracic pleuron and abdominal venter variably infuscate; femora with some dark spots; dorsal tibial spines with tiny dark spots at bases; tibiae dark at femoral articulation. SURFACE AND VES TITURE: Dorsum weakly granular, smooth, weakly shining. Vestiture of dorsum composed of recumbent, pale, simple setae with darker suberect setae on pronotum and anterolaterally on hemelytra. STRUCTURE: Body elongate, nearly parallelsided; frons moderately tumid as viewed from above, clypeus visible; anteocular distance 1.3 times diameter of antennal segment 1; head projecting below eye by diameter of antennal segment 1; labium long, reaching beyond hind coxae onto abdomen. GENITALIA (fig. 30): Vesica sigmoid, body relatively heavy, base falling somewhat below base of secondary gonopore; posterior apical spine short, erect, extending only moderate distance past secondary gonopore, anterior spine much longer, slender, and angled just before midpoint; no flange.
Female:
Shorter and more strongly ovoid than male; coloration similar to male. Total length 4.17–4.23, length apex clypeus–cuneal fracture 2.92–3.01, width across pronotum 1.31–1.36.
ETYMOLOGY: Named for its occurrence on
Phacelia
spp.

(Hydrophyllaceae)
