NEW SYNONYMY.  DIAGNOSIS: Distinguished from other  flavipes-group species by the strong sexual dimorphism, the male subparallel sided and distinctly elongate posterior of the costal fracture and the female shorter with slightly arcuate costal margins (pl. 2); the completely black appendages including the antennal segments and femora, except for the pale yellow apices (fig. 13); the dense, long, suberect, silvery or golden vestiture; and the short dorsal portion of the dorsal lobe of the endosomal spicule (fig. 44C–H, arrow). The female of  S. longipenniscan usually be discriminated from female  S. flavipesand  S. pilosusby the yellowish pale apex of the femur, the yellowish or black tibia, and the black antenna and tarsomeres. In  S. flavipesthe tibiae and apices of the femora are more pale orange than yellow and antennal segments I and II are mostly pale yellow; in  S. pilosusantennal segment I and II are mostly pale and tarsomeres I and II are pale.  REDESCRIPTION: Male:Large, elongate; length 4.80–6.00, width 1.63–2.10 (pl. 2). COLORATION: Black; including antenna, femur except for narrowly pale yellow apex, tibia pale or dusky yellow to black (fig. 13). VESTITURE: Dense, moderately long, suberect, silvery simple setae; sometimes vestiture somewhat golden. STRUCTURE: Hemelytron elongate, costal margin subparallel. GENITALIA: As in species group except: Phallotheca: As in figure 44A, B. Endosomal spicule: Dorsal lobe with narrow dorsal portion usually as long or shorter than wide basal portion; serration of basal portion variable (fig. 44C–H). Right paramere: Subapical region short with variable number of small spines (fig. 43B–G). Left paramere: Distal portion short, with abrupt contraction at junction with paramere body (fig. 43A).  Female:Moderately large, obovate; length 3.50–4.50, width 1.60–2.08 (pl. 2). COLORATION: Tibia always pale yellow to pale yellowish brown. STRUCTURE: Costal margin slightly arcuate. GENITALIA: As in species group except: Vestibulum, anteroventral margin of anterior wall: Sclerotized medially, and sclerotized to lateral margins of bursa copulatrix. Ventral labiate plate: Strongly produced, moderately wide, triangular at base sometimes apex cleft. Second gonapophyses: Anterior medial surface strongly convex. Interramal sclerite: With dorsomedial region convex anteriorly and posteromedial portion with flat plate abutting ovipositor bulb. Interramal lobe: Basal (dorsal) insertion with membranous attachment, dorsomedial margin not produced as lobe.  HOSTS: The predominant breeding hosts can be adduced from sites in Nye County, Nevada, where intensive collecting was undertaken by R.T. Schuh and colleagues. In the southernmost portion of the range, specimens were taken in relatively large numbers from  Ericameria nauseosa,  Gutierrezia sarothrae, and  Tetradymia glabrata. This is the only species of  Slaterocoristaken on  Tetradymia. Other Orthotylinito partially utilize species of this widespread western plant genus are  Lopidea bullataKnight, 1923, and  Aoplonema rubrum Forero, 2008. Schuh (2008) discussed the host associations of  Beckocoris Knight, 1968, and  Nevadocoris Knight, 1968, two phyline plant buggenera that are more closely tied to  Tetradymiaspecies, than these Orthotylini. Host records from more northern portions of the range indicate that  Artemisia tridentatais probably the breeding host. Some specimens were taken on  Chrysothamnus viscidiflorusthroughout the distribution of  S. longipennis. Only two specimensoccurred on non-asteraceous plants, and these are considered to be sitting records.  DISTRIBUTION: This species is predominantly an inhabitant of the scattered ranges of the Great Basin in Nevadaand the intermountain west of Coloradoand Utah. The western limit borders the basin at the eastern slope of the Sierra NevadaMountains of California, stretching from Fresno to Shasta Counties. The northern limit of the range of  S. longipennisis apparently the northern extent of the Snake River Plain in Idaho. The eastern limit is found in the northwest quadrant of the ColoradoRocky Mountain cordillera ( map 10).  DISCUSSION: The right paramere shows limited variation from across the distribution of  S. longipennis. Minor differences in the conformation of the apical spines exist in males from California, Colorado, Nevada, Utah, and Wyoming(cf. fig. 43B–G). The structure of the dorsal lobe in the endosomal spicule is remarkably uniform, only the intensity of the marginal serration being variable. All individuals are recognizable by the relatively short region dorsal to the expanded base (fig. 44C–H).  Knight (1968)described  S. longipennisand  S. utahensisconsecutively, discriminating between them by overall size, coloration of the vestiture and tibiae, comparison of antennal segment II length to head width, and the structure of the right paramere. Examination of the holotypesdemonstrated that  S. longipennishas greater body length (5.60), pale vestiture and tibiae, longer antennal segment II (1.19), and the right paramere with four apical spines, while  S. utahensishas shorter overall length (4.80), dark vestiture and tibia, shorter segment II (1.02), and three spines on the right paramere. Kelton (1968)followed Knight and recognized  S. longipennisand  S. utahensison the same features, giving weight to overall size and coloration of the tibiae and vestiture. Another species,  S. knowltoni, was described by Knight (1970)based on three malesfrom Box Elder County, Utah, without reference to either of the former species; it was distinguished by black legs, moderately dense, suberect, brown vestiture, antennal segment II not longer than the head width, and structure of the right paramere. The holotypeand a paratypeof  S. knowltonihave body length of 3.98 and 4.80, antennal segment II length of 0.93 and 1.03, and right paramere with three and four spines, respectively. Examination of paratypesof  S. longipennis, the only one of these three species founded on a relatively large number of specimens, taken from one collection event, revealed variation in the tibial coloration, ranging from pale yellow, yellowish brown to brown. Specimens that fit the diagnosis of the three nominal species showed variability in overall size (4.80–6.00), antennal segment II length (1.03–1.30), tibial coloration, and number of apical spines of the right paramere (fig. 43B–G). The color of the dorsal vestiture ranges from pale silvery to darker golden. None of these characters are tied to a particular geographic region. In light of these observations, I propose treating  S. knowltoniand  S. utahensisas junior synonyms of  S. longipennis.   HOLOTYPES:  USA: Nevada: Nye Co.: Mercury, 19 M [ 36.660566 N 115.993616 W], 24 Jun 1965, H.H.
