PARATYPE: [USA] Wyoming: Park Co.: Yellowstone National Park [44.76667°N 110.23333°W] 20 Jul 1920 – 25 Jul 1920 [1925 in original description], A.A. Nichol, 1♂ (00096918) (AMNH).

PARATYPES: [USA: Colorado: Clear Creek Co.] Berthoud Pass [39.79805°N 105.77777°W] 3452 m, 17 Jul 1964, H.H. Knight, 1♂ (00096919) (AMNH). Orectoderus cockerelli: HOLOTYPE: Male: [USA: Colorado: Teller Co.] Florissant [38.94555°N 105.28916°W], Jul 1916, T.D.A. Cockerell, Potentilla fruticosa (Rosaceae) (AMNH_PBI 00068981) (USNM). DIAGNOSIS: Recognized by greyish aspect of pronotum (fig. 3), golden, shiny pubescent setae on pronotum and wide and strongly sclerotized vesica (fig. 5); most similar to O. longicollis in vesica and pronotum shape and pronotal vestiture, distinguished by its brown clavus and pale band parallel to claval suture; female with large sclerotized rings, pointed apically (fig. 11). In general aspect, vesica and vestiture similar to montanus, but distinguished by leπ paramere with long seta on inner surface of anterior process (fig. 6), and vesica with denticulate lobe, in lateral view, straight (fig. 5, arrow). REDESCRIPTION: Male: Total length 5.45–6.71, length apex clypeus-cuneus fracture 3.82– 5.00, width across pronotum1.23–1.48. COLORATION: Clavus brown with narrow pale band parallel to claval suture (fig. 3); corium brown with pale band parallel to claval suture usually ending just right before or slightly reaching apex of clavus. SURFACE AND VESTITURE: General aspect rugose, pubescent and faintly shiny; pronotum and scutellum faintly shiny; dorsal surface and pronotum bearing fine, pale reclining setae shorter than diameter of first antennal segment. STRUCTURE: Labium reaching to mesocoxa. GENITALIA: Secondary gonopore with large denticulate lobe, in lateral view, straight (fig. 5); anterior process of leπ paramere bearing distinct long seta on inner surface (fig. 6). Female: Total length 4.62–5.63, width across pronotum 0.91–1.09. COLORATION: Head, pronotum, mesoscutum, scutellum and hemelytra greyish brown (fig. 3). SURFACE AND VESTITURE: General aspect dull; head and pronotum dull; pronotum clothed with fine, pale setae. STRUCTURE: Second antennal segment just slightly inflated distally (fig. 3). GENITALIA: Sclerotized rings of dorsal labiate plate large, elongate, and pointed apically; posterior wall with bifurcate interramal sclerites, almost straight medially (fig. 11). HOSTS: Chrysothamnus nauseosus (Asteraceae), Symphoricarpos sp. (Caprifoliaceae), and Potentilla fruticosa (Rosaceae). DISTRIBUTION: Canada: Alberta, Saskatchewan. United States: Colorado, Idaho, Montana, Nevada, North Dakota, Utah, and Wyoming (map 2). DISCUSSION: The shape of the pronotum among specimens of Orectoderus montanus is slightly variable, but always more or less dis- MAP 2. Distribution of Orectoderus montanus. tinctly campanulate with the outer distal margin concave. Examination of the holotype and paratype of O. utahensis, holotype and paratype of O. salicis Knight, and the holotype of O. cockerelli (the only known specimen) suggests that these nominal species are the same as montanus. Their general aspect, vestiture, and second antennal segment do not show any differences, and I am therefore treating the first three as junior synonyms of the last, new synonymy. O. montanus, O. cockerelli, O. salicis, and O. utahensis were described in the same publication (Knight, 1968a). The last three species have not been discussed subsequently, whereas O. montanus was redescribed by Kelton (1980). For this reason, maintaining nomenclatorial stability, O. montanus is chosen here as senior synonym. SPECIMENS EXAMINED: CANADA: Alberta: Clarinda, 49.09566°N 111.74316°W, 960 m, 15 May 1952, L.A.
