DIAGNOSIS: Distinguished by the mostly yellow coloration of the appendages. Antennal segments I and II are pale, except for the brown base of segment I and apical one-fifth of segment II. The legs are predominantly pale yellow with dark brown to black on most of the basal portions of the femora, apices of the tibiae and distal tarsomeres (fig. 13). The structure of the right paramere and endosomal spicule will unequivocally distinguish the male (fig. 33A–C, I–L). The female of S. pallidicornis is difficult to separate from female S. breviatus with extensive pale coloration in antennal segment II. Additionally, the base of segment II in the female of S. pallidicornis is pale as compared to those of S. breviatus which often have segment II pale, but the extreme base and apex are black. Usually the pale portion of the appendages of the latter species are more orange-yellow as compared to the pale yellow of the former. Typically the trochanter and antennal segment I are pale in S. pallidicornis , the trochanter is dark and segment I has a black basal annulus in S. breviatus . Sometimes the distal portion of antennal segment II is diffusely darkened in female S. pallidicornis , the extreme base is not narrowly darkened; in female S. stygicus , segment II is pale yellow medially, with dark base and distal region. Additionally, the hemelytron in female S. pallidicornis is shorter anterior to the cuneal fracture and the width of the corium is somewhat narrower, as compared to female S. stygicus where the anterior portion of the hemelytron is longer and with of the corium is wider.

REDESCRIPTION: Male: Large, obovate, length 4.10–4.75, width 1.81–2.10 (pl. 2). COLORATION: Shining black; except pale yellow on antennal segments I (except for extreme base) and II, (except variable distal region), apex of coxa, trochanter, apical portion of femur, tibia except apex, and tarsomeres I and II. (fig. 13). VESTITURE: Sparsely distributed, short, suberect, brown setae. STRUCTURE: Frons striate; labium reaching middle of middle coxa; antennal segment II longer than head width; costal margin arcuate. GENITALIA: Tergal process: Long, basal width and apical points variable (fig. 33D, E). Endosomal spicule: Ventral lobe long, somewhat flattened (fig. 33A, arrow) or narrow (fig. 33B, C, arrow) marginal serration strong, restricted to apical region; dorsal lobe with lateral ramus long, flat distally, relatively wide, attenuate apically, marginal serration strong; base of lateral ramus sometimes curved (fig. 33A, B); medial ramus moderately long, marginally smooth (fig. 33A–C). Right paramere: Apical spines tightly grouped, moderately long, discrete, splayed, with basalmost spine about same width as others, not separated (fig. 33I–L, arrow); basal lobe with serrate region produced, not particularly constricted, strongly serrate on posterior surface (fig. 33I–L); sometimes basal lobe with several large basal spines (fig. 33K, arrow). Left paramere: Long; apex smoothly attenuate (fig. 33F–H).

Female: Large, ovate; length 4.20–4.60; width 2.00–2.24; costal margin strongly arcuate (pl. 2). COLORATION: Antennal segments I and II almost completely yellow, but with extreme base of segment I and extreme base and apex of segment II black. GENITALIA: As in species group except: First gonapophyses: Right greater than left at overlap. Second gonapophyses: Anterior medial surface strongly convex. Interramal sclerite: Posteromedial portion with flat plate abutting ovipositor bulb.

HOSTS: The majority of host records are from Asteraceae or Caprifoliaceae . Artemisia (with A. cana the only species-level record), Aster sp. , and especially species of Solidago are probably the breeding hosts for this species. However many specimens were collected on honeysuckle, Lonicera sp. and Symphoricarpos species (common snowberry, S. albus (L.) Blake, western snowberry, S. occidentalis Hook. , and coralberry, S. orbiculatus Moench ) across the northern portion of the distributional range of S. pallidicornis . I hesitate to suggest that the large number of occurrences on these woody perennials are just sitting records as the detailed biology of this species is essentially unknown; perhaps species of Caprifoliaceae are an essential component of its life cycle. Plant bugs are known to feed on flowers and pollen of nonbreeding hosts ( Wheeler, 2001); the single instance of Yucca glauca Nutt. (Agavaceae) is considered to be a sitting record.

DISTRIBUTION: A species of the Prairie Provinces and the upper Great Plains with a significant number of records in the Rocky Mountain cordillera of Colorado and an apparently isolated population in maritime Canada. Occurs as far north and west as the Peace River region of Alberta then east spanning the Prairie Provinces to western Ontario. In the upper Great Plains, it extends from the Canadian border south to Iowa, Nebraska, and Wyoming, and is found on the eastern front of the Rockies from Colorado north to Alberta. Known from only one locality (22 specimens, 2 collection events) in Cape Breton Island, Nova Scotia ( map 7 ).

COLLECTION SUMMARY: 439 specimens (58 % with USI numbers) from 191 collection events, with June records found in the southern plains localities and the remainder of specimens collected in July to August, as the latest record is from early September.

DISCUSSION: Variation was noted in the male genitalia of some males from Nova Scotia. In the endosomal spicule the lateral ramus in the dorsal lobe is sometimes twisted (cf. fig. 33B, C) and right paramere sometimes has accessory spines basal to the apex of the basal lobe (cf. fig. 33J, K). The structure of the tergal process in some males from Nova Scotia was more narrow basally and with small apical points than in other males (cf. fig. 33D, E). Such variation was not noted in specimens in the remaining distribution of S. pallidicornis . The apical spines of the right paramere in some S. pallidicornis are reminiscent of the condition found in S. breviatus , but upon close comparison the individual spines of S. breviatus are smaller, more distinct and more equal in length than those of S. pallidicornis .
