TYPE MATERIAL (EXAMINED): Orectoderus bakeri : HOLOTYPE: Male: [ USA: Colorado: Routt Co.] Steamboat Springs [40.485°N 106.83111°W], 2103 m, 11 Jul 1964, H.H. Knight ( AMNH _ PBI 00069008 ) ( USNM) . PARATYPES: [ USA: Colorado: Routt Co.] Steamboat Springs [40.485°N 106.83111°W], 2103 m, 15 Jul 1964, H.H. Knight, 1♂ (00096197) ( AMNH) .

Teleorhinus oregoni : HOLOTYPE: Male: [ USA: Oregon: Klamath Co.] Summit of Bly Mountain [42.40389°N 121.43611°W] 17 Jun 1934, Joe Schuh ( AMNH _ PBI 00068798 ) ( USNM).

PARATYPE: [ USA: Oregon: Klamath Co.] Summit of Bly Mountain [42.40389°N 121.43611°W] 17 Jun 1934, Joe Schuh , 1♂ (00121388) ( CNC) .

DIAGNOSIS: For coloration of hemelytra, see Orectoderus arcuatus ; males as well as females with pronotum bearing strong, erect, pale setae longer than diameter of first antennal segment; pronotum more rugose, not shiny; leπ paramere with anterior process not bearing distinct long setae on inner surface (fig. 6); common oviduct of female genitalia with sclerotized spots laterally (fig. 11). Similar to O. arcuatus in general aspect, vesica, and female genitalia, but distinguished by more rugose pronotum bearing strong, pale setae and anterior process of leπ paramere without distinct long seta on inner surface, as O. arcuatus (fig. 6) and in female by common oviduct with much smaller sclerotized spots laterally than in O. arcuatus and sclerotized rings of dorsal labiate plate more pointed apically (fig. 11); further the rather fuscous colored specimens similar to O. montanus but distinguished by the much stronger and erect pronotal setae in contrast to recumbent and fleecy pronotal setae in O. montanus , and vesica in O. montanus (fig. 5) much stronger than in O. bakeri (fig. 5).

REDESCRIPTION: Male: Total length 6.61–7.77, length apex clypeus-cuneus fracture 4.84– 5.42, width across pronotum1.36–1.64. COLORATION: Corium either brown with pale or reddish white band parallel to claval suture reaching apex of clavus or with pale band extending around inner apical angle of corium reaching to pale basal part of cuneus. SURFACE AND

VESTITURE: General aspect rugose and dull; pronotum and scutellum rugose and dull; pronotum with strong, erect, pale setae longer than diameter of first antennal segment. STRUC-

TURE: Labium reaching to mesocoxa. GENITALIA: Anterior process of leπ paramere without distinct long seta on inner surface (fig. 6).

Female: Total length 5.12–5.62, width across pronotum 0.94–1.10. COLORATION: Head, pronotum, mesoscutum, scutellum, and hemelytra brown-orange. SURFACE AND VESTI-

TURE: General aspect dull; pronotum bearing strong, erect, pale setae. STRUCTURE: Second antennal segment very strongly inflated distally (fig. 3). GENITALIA: Sclerotized rings of dorsal labiate plate rounded basally and apically; posterior wall with bifurcate interramal sclerites, distinctly pointed medially (fig. 11).

HOSTS: Artemisia cana , A. tridentata , Chrysothamnus viscidiflorus (Asteraceae) , Lupinus sp. ( Fabaceae ), and Purshia tridentata (Rosaceae) .

DISTRIBUTION: United States: California, Colorado, Idaho, Oregon, Utah, and Wyoming (map 1). Knight (1968a) mentioned that bakeri is a species occurring mainly at higher elevations.

DISCUSSION: Knight (1968b) described Teleorhinus oregoni based on two males from the summit of Bly Mt. in Oregon. He distinguished this species from all other known Teleorhinus species by its dull, opaque pronotum, the only character he proposed. He apparently placed it in Teleorhinus because of its rugose pronotum and scutellum, a main character of Teleorhinus , and the completely fuscous dorsal surface. The holotype and paratype, the only known specimens of T. oregoni , present the following characters for transferring oregoni from Teleorhinus to Orectoderus and for synonymizing it with bakeri : the dull, distinct trapezoidal pronotum, the strong, pale, erect pronotal setae, and the form of the vesica and the leπ and right parameres.

The vesica of O. bakeri and O. arcuatus is distinctly smaller compared to that in all other species of Orectoderus (fig. 5); bakeri and arcuatus are the only two species within Orectoderus in which the corium sometimes shows a red coloration.
