03DA87E8FFE4FFCCF5CD8EC3BECCFAD3.taxon	discussion	Remarks. This diverse genus is superficially similar to many genera within the Callidiini including Xylocrius, Hylotrupes, Callidium, Ropalopus, and Pyrrhidium in that they share a similar habitus and have a pronotum that is variously sculptured. They differ from these species in that the front coxae are divided by a narrow prosternal process, tarsal claws are simple, the femora only slightly clavate and apical antennomeres dorso-ventrally flattened.	en	James Hammond, H.

03DA87E8FFF8FFD0F5CD8DABB8EAF80A.taxon	discussion	Remarks. The mandible in the type specimen A. canadensis has only a remnant of the median mandibular tooth, with wear marks visible on the molar surface of the mandible. This species is very similar to S. litigiosus, however, the overall habitus is longer and narrower, is often lighter colored and usually smaller in size. The elytral sutural flying hairs in this species tend to be longer, giving the elytra a somewhat pubescent keeled appearance. Eastern forms are relatively easy to separate as they tend to be smaller and more dull brown in color. In the west, this species is often larger than eastern forms, and is confused with teneral or lighter colored specimens of S. a. basalis due to the elytra sometimes having lighter banded or spotted areas of color, however the characters in the key should separate the two species. There is a distinct population of this species in higher elevations of Wyoming and Colorado. The antennae tend to be longer in this population, but the elytra still tends to be longer and narrower and the coloration is more similar to eastern forms. Some specimens also have unusual bi-colored femora.	en	James Hammond, H. E., Williams, Daryl J.

This species can be separated from other species of Semanotus by the following combination of characters: color dark brown to black, rarely with tibia, tarsi and basal antennomeres lighter, rarely abdomen orange; elytra yellow (rarely) to orange (usually) except for black maculation on the humeri, one pair of median moderate to large black spots and apical 1 / 3 of elytra; elytral pubescence entirely dark, coarse, decumbent to recumbent, obscuring the surface somewhat making the elytra appear somewhat dusky grey; elytral humeri with patch of long, decumbent white setae which extends along humeri from base to about middle of elytra; overall antennal length short, especially in female; antennomeres 1 – 3 short, with dense field of contrasting pale colored setae on anterior surface; clypeus deeply impressed and curved or with medially acute posterior margin, which forms a ‘ Y’ shape with median frons groove; ventral pubescence white to grey, semi-erect to decumbent, coarse, long, dense, surface of ventrites usually obscured.

03DA87E8FFFEFFD7F5CD8B1AB8D1FE0A.taxon	discussion	Remarks. This species is probably the most difficult of all Semanotus to identify as it can be easily confused with S. a. basalis, as they share a similar coloration. The ground color of this species is often duller with a matte finish that may be due to a thicker wax layer on the cuticle to assist with dessication in hot environments (however, no significant microsculpture was noted). Whereas, most specimens of S. amplus tend to have a very shiny, lustrous appearance. The females of this species have notably shorter antennae, which barely reach the middle of the elytra. The ventral pubescence is very dense usually obscuring the sternites. Antennomeres 1 – 3 have a distinct area of long, white, semi-erect to decumbent setae especially on the dorsal surface, whereas most specimens of S. amplus have shorter, white, decumbent setae that encircle the antennomeres. The elytral punctation of S. conformis also tends to be less foveate and more widely separated than S. amplus.	en	James Hammond, H. E., Williams, Daryl J.

03DA87E8FFFDFFDBF5CD89F3B8FEFE69.taxon	diagnosis	Diagnosis. This subspecies can be separated from other subspecies of S. amplus by the following combination of characters: head, pronotum, and abdomen dark brown to black; antennal scape light to dark brown, usually contrasting with remaining antennomeres which are light brown to orange; femur dark brown and contrasting with tibia and tarsomeres which are light brown to orange; elytra light to dark orange, rarely red, with small to medium round to ovoid median black spot, 1 / 3 of apex black; elytral disk pubescence unicolour black, somewhat decumbent; ventral body and leg pubescence white to grey, moderately dense and long, usually not dense enough to obscure surface; elytral base and humeral angle orange, humeral angle short, usually less than ¼ of elytra making the elytra appear flat and wide. Hosts. Libocedrus decurrens (incense-cedar), Thuja plicata (western redcedar), Juniperus occidentalis (western juniper), J. scopulorum (Rocky Mountain juniper), Sequoia sp. Flower and Associated Vegetation Records. Pinus sp., Chaemycparis nootkatensis (yellow cedar), Abies sp. Distribution. Southern California north to central British Columbia, Pacific Coast east to continental divide. Remarks. There seems to be a color cline in this subspecies, with southern populations tending to be lighter orange and northern populations becoming dark orange to almost red. Also, specimens from Libocedrus and Thuja tend to be dark orange with dark grey highlights, whereas, specimens from Juniper tend to be a lighter orange. In California this species may be bivoltine, as there appears to be two distinct adult activity periods, one from March to early May, and another from late August through to mid-September.	en	James Hammond, H.

This subspecies can be separated from other subspecies of S. amplus by the following combination of characters: elytral disk usually distinctly bicolored with basal 1 / 3 light brown to red and apical 2 / 3 dark brown to black; elytral humeral angles usually light brown but occasionally markedly darkened similarly to S. a. basalis; antennae are dark brown to black.

03DA87E8FFF1FFDFF5CD887ABBABFE52.taxon	discussion	Remarks. This subspecies tends to be the most characteristic form among subspecies of S. amplus. The coloration is fairly distinctive in that it ranges from completely black to the basal 1 / 3 of elytra orange to red and the apical 2 / 3 black. The legs and antennae generally are entirely black, however, there is variation in this character. The punctures in the apical ½ of the elytra tend to be closer together than in the basal pale area, with slightly more foveate punctures which gives the surface a somewhat wrinkled appearance. We examined one series of specimens (9 males, 11 females) reared from Sequoia sempervirens, March 24, 1920, from Falls Church Virginia. The specimens all had the same Hopkins Number [Hopk. U. S. 16160 a], however, there was no collector information. We presume that these specimens were either collected from a transplanted tree, nursery stock, arboretum, or a log, that originated from the west coast and was shipped to Virginia.	en	James Hammond, H.

03DA87E8FFF7FFE3F5CD881ABA94FF72.taxon	discussion	Remarks. The allotype of this species is housed at the Essig Museum (EMEC) and not at the California Academy of Sciences (CAS) as was published in Giesbert (1993), and the Florida State Collection of Arthropods (FSAC) has a series of paratypes. The holotype (a male) is listed as being at the CAS, however, this species is not listed in the primary type catalogue database. A male specimen of the melanic form of this species has been intercepted by APHIS in Pharr County, Texas on fruit of Phaseolus vulgaris from Honduras (label data, USNM). Coloration in this species is highly variable, ranging from all black, to bicolored, to maculate with no noticeable differences in morphology.	en	James Hammond, H. E., Williams, Daryl J.

This species superficially resembles S. litigiosus, however, it lacks the median mandibular tooth, the row of setae along the elytral suture are more sparse and rather indistinct, the legs are much longer and much less clavate, and the appendages and abdomen are much lighter in color, contrasting with the head and prothorax. A single specimen of this species was intercepted in British Columbia from a wooden box containing mandarin oranges from Japan, and was sent to the United States for identification.	en	James Hammond, H.
