Cerambycinae

Batyle ignicollis ignicollis (Say, 1824)

Three adults of this bright red and black species were collected in southern Idaho, Cassia Co., 6 mi. NE Malta, 11-VIII-1953, on Atriplex confertifolia , T . B. O’ Connell. The reported range is Ohio , Missouri , and Texas westward to Colorado and Montana (Linsley 1962). The Idaho specimens represent a NEW STATE RECORD .

Callidium antennatum hesperum Casey, 1912

This species occurs in Oregon, Washington, Utah, Wyoming and several other states but has not been documented from Idaho ( Linsley 1964). Eighteen specimens were collected at several locations in Latah Co. including Paradise Ridge, 7-V- 1932, J. Gillett, (8); Cedar Mtn., 9-VI-1935, K. E. Gibson, (1); and Moscow Mtn., 7-IX-1965, M. M. Furniss, (1). These adults represent a NEW STATE RECORD for Idaho .

Callidium cicatricosum Mannerheim, 1853

Linsley (1964) records this species from Alaska to Oregon and the northern Rocky Mountains. Heffern (1998) included Idaho in the distribution of this species, apparently based on examination of specimens but without further information. We are not aware of other literature records from Idaho. However, its presence in the state is confirmed by 33 specimens collected in Boundary Co., Priest Lake, 6-VI-1986, Pseudotsuga menziesii, M. M. Furniss , (2); Latah Co., including 1.5 mi. N Kendrick, 3-III- 1970, reared Douglas fir, R. L. Penrose, (10); Moscow, 2-IV-1972, R. W. Portman, (6); Moscow Mtn., 10-VI-1931, P. Rice, (1); and Robinson Lake, 6-V-1955, W. F. Barr, (1); plus Clearwater Co., Pierce, 23-V-1929, W. E. Shull, (1); Kootenai Co., Beauty Creek, 2-VII-1975, D. F.

This species is known from British Columbia to Utah and Arizona ( Linsley 1964). Nine adults were collected in Cassia Co., 5 mi. SW Malta, 29-IV- 1968, on Juniperus, W. F. Barr. This represents a NEW STATE RECORD for Idaho .

Callimus cyanipennis (LeConte, 1873)

Linsley (1963) records this species (until recently placed in the genus Lampropterus Mulsant ) from flowers of Ceanothus and Prunus , with a distribution from Oregon to southern California. Two adults were collected in northern Idaho, Kootenai

Co., 2 mi. W Lataldo , 21-V-1970, W. F. Barr, (2). These specimens represent a NEW STATE RECORD for Idaho and extend the range northward for the species .

Clytus canadensis Hopping, 1928

This species is recorded from British Columbia and Alberta southward to southern Oregon and Colorado ( Linsley 1964). Heffern (1998) included Idaho in the distribution of this species, apparently based on examination of specimens but without further information. We are not aware of other literature records from Idaho. However, its presence in the state is confirmed by four specimens from northern Idaho, all collected in Latah Co. as follows: Moscow, no date (probably early 1900s), J. M. Aldrich (1); Moscow Mtn., 17-VII-1981, on Achillea, W. F. Barr , (2), University of Idaho Experiment Forest, Flat Creek, 2-VI-2004, P. M. Callahan, ex. Japanese beetle trap in topped Pinus ponderosae , (1).

Haplidus testaceus LeConte, 1873

Linsley (1962) notes that this species is a “typical Great Basin species.” A single specimen was taken in southwestern Idaho, Boise Co., Horseshoe Bend, V-1955, W. Roe. This represents a NEW STATE RECORD for Idaho .

Megacyllene robiniae (Forster, 1771)

This species is intimately associated with the larval host black locust, Robinia pseudoacacia L., and occurs throughout the eastern USA and Great Plains ( Linsley 1964). More recently, it appears to have spread, either naturally or through introduction, into areas where black locust has been planted as an ornamental such as into south-central Montana ( Hart et al. 2013) and Oregon (Westcott et al. 2006). Heffern (1998) included Idaho in the distribution of this species, apparently based on examination of specimens but without further information. We are not aware of other literature records from Idaho. However, its presence in the state is confirmed by adults collected in extreme northern and southern Idaho at Bannock Co., Pocatello, 19- VI-1968, R. L. Penrose, (3), Bonner Co., Priest Lake, 25-VII-1969, V. Maag, (1); Canyon Co., Nampa, IX- 15-1980, C. R. Baird (9); Latah Co., 2 mi. S Moscow, IX-15-2008, F. W.

Meriellum proteus (Kirby, 1837)

In western North America, this species has been collected in Alaska southward to British Columbia and Colorado ( Linsley 1964). Heffern (1998) included Idaho in the distribution of this species, apparently based on examination of specimens but without further information. We are not aware of other literature records from Idaho; however, its presence in the state is confirmed by a single adult collected in Latah Co., Moscow, Moscow Mtn., 1- VIII-1953, R. Abbott.

Molorchus longicollis LeConte, 1873

This species occurs from British Columbia to southern California ( Linsley 1963) and throughout western Montana ( Hart et al. 2013) but has not been reported from Idaho.

the state is confirmed by two specimens collected in Latah Co., Moscow , IV-1995, reared Picea abies, M. M. Furniss , (2) and representing a NEW LARVAL HOST RECORD .

Phymatodes nigerrimus Van Dyke, 1920

Linsley (1964) noted that this species was rare in collections. It has been recorded only from California. One specimen was taken in Latah Co., Moscow Mtn., 29-VI-1918, A. L. Melander. The specimen is in the entomology collection of Washington State University, Pullman. This singular specimen represents a NEW STATE RECORD for Idaho .

Phymatodes nitidus LeConte, 1874
