Orectoderus longicollis Uhler, 1895: 47 (new species); Van Duzee, 1916b: 42 (list), 1917: 368 (catalog, distribution); Carvalho, 1958: 175 (catalog); Knight, 1968a: 313 (discussion); Knight, 1968b: 64 (distribution, figure of head and antenna, diagnosis); Polhemus, 1994: 130 (distribution, host).

TYPE MATERIAL (EXAMINED): Orectoderus longicollis : Holotype: Male: [ USA: Colorado: Routt Co.: Steamboat Springs, 40.485°N 106.83111°W] Colo 1341 [Baker], Lupinus sp. ( Fabaceae ) ( AMNH _PBI 00068904) ( USNM).

DIAGNOSIS: Recognized by coloration of hemelytra with clavus almost entirely pale, brown only proximally (fig. 3); vesica strongly sclerotized with wide denticulate lobe (fig. 5); leπ paramere with anterior process rounded apically (fig. 6); female with small sclerotized spots beyond apex of sclerotized rings of dorsal labiate plate (fig. 11, arrow). Most similar to O. montanus in general aspect, vestiture, and vesica, but distinguished by claval coloration, length difference between anterior and posterior process of leπ paramere (fig. 6), inner surface of anterior process of leπ paramere without long seta as in O. montanus (fig. 6) and vesica with denticulate lobe, in lateral view, concave (fig. 5, arrow).

REDESCRIPTION: Male: Total length 6.00–6.66, length apex clypeus-cuneus fracture 4.46– 4.89, width across pronotum1.28–1.44. COLORATION: Pronotum black, slightly greyish; clavus pale, brown just proximally and with very narrow brownish band along claval commissure; corium brown with pale band parallel to claval suture reaching apex of clavus. SURFACE AND

VESTITURE: General aspect dull, rugose, and pubescent; pronotum and scutellum dull; dorsal surface clothed with pale setae; pronotum bearing fine, pale reclining setae shorter than diameter of first antennal segment. STRUCTURE: Labium reaching to mesocoxa. GENITALIA: Anterior process of leπ paramere without distinct long seta on inner surface (fig. 6); secondary gonopore with large denticulate lobe, in lateral view, concave (fig. 5, arrow).

Female: Total length 5.11–5.34, width across pronotum 0.91–1.09. COLORATION: Head, pronotum, mesoscutum, scutellum, and hemelytra greyish brown (fig. 3); ocher band along claval suture. SURFACE AND VESTITURE: General aspect dull with greyish appearance; head and pronotum dull; pronotum clothed with fine, golden, shiny setae shorter than diameter of first antennal segment. STRUCTURE: Second antennal segment just slightly inflated distally (fig. 3). GENITALIA: Sclerotized rings of dorsal labiate plate rounded basally and tapering apically; small sclerotized spots beyond apex of sclerotized rings of dorsal labiate plate; posterior wall with bifurcate interramal sclerites, rounded medially (fig. 11).

HOSTS: Symphoricarpos sp. ( Caprifoliaceae ), Lupinus sp. ( Fabaceae ), and Purshia tridentata (Rosaceae) .

DISTRIBUTION: United States: California, Colorado, and Wyoming (map 1) .

DISCUSSION: Uhler (1895) described this species from a single male from Steamboat Springs, collected by Baker on July 14. The specimen in the collection of the USNM labelled “Colo. 1341” fits Uhler’s (1895) indication. “Colo. 1341” is Baker’s code for “Steamboat Spring, Colorado ” (Tom Henry, personal commun.). Even though this specimen does not bear any type label, it is doubtless the holotype of O. longicollis .

Orectoderus longicollis is the only species within this genus with a pale clavus or, as Uhler (1895) specified it, with “clavus ivory white.”
