( Fig 7 B, 16B; Map 2)

Hylotrupes juniperi Fisher, 1915: 77

Material examined. 37 males, 44 females.

Holotype. Male ( USNM), examined; labelled “SantaCata/lina Mts/Ariz// Dec. 1/14 //Edmonston/WDColr// Juniperus /pachyphloca//12698/Hopk. U.S. //3// Hylotrupes / juniperi /Fisher/W.S.F.// Type /No.19129/ U.S. N.M. [Red label]”.

Diagnosis. This species can be separated from other species of Semanotus by the following combination of characters: color black; pronotum broadly round, with basal stalk forming a short pedicel between pronotum and elytra; antennae long, usually>1/2 elytra length in male, ≥1/2 elytral length in female; antennomeres 1, 3–5 short and stout, ~ 2X as long as wide, especially in male; elytra minutely punctate, moderately rugulose near base; wing vein r3 long; wing vein RP long; tibia with long, erect setae (“flying hairs”) greatly reduced in males, absent in females; basal apophysis of abdominal sternum VIII short, about the length of one lateral sclerite; basal apophysis of spiculum ventrale long, ~2.5X length of lateral apophysis; ventral lobe of aedeagus apically broadly rounded and evenly constricted, dorsal lobe of aedeagus broadly rounded.

Hosts. Juniperus osteosperma (=utahensis) (Torr.) Little (Utah juniper), J. deppeana (=pachyphloea) Steud. (alligator juniper).

Flower and Associated Vegetation Records. Thuja sp. (cedar).

Distribution. High elevation or arid areas of California, Idaho, Nevada, Colorado, Arizona, New Mexico and Texas.

Remarks. This species is structurally similar to S. amethystinus ; however, we noted several minor differences in wing venation and genitalia. This species also appears to breed in junipers rather than in cedars.
