TeNeBROIDeS cOLLARIS (Sturm, 1807) , New State Record

Fig. 3 View Fig

This unmistakable species is easily recognized by its combination of a depressed body with orange-red head and pronotum, and relatively smooth, black elytra ( Fig. 3 View Fig ). Prior to records presented here, the distribution of T. collaris was listed as “Eastern United States, Ontario, west to Michigan, eastern Texas ” by Barron (1971). The furthest northwestern US record documented by Barron (1971) was Alpena, Alpena County, Michigan, in the far northeastern portion of that state, while the furthest southwestern record was from Grayburg, Hardin Co., Texas. In Montana, this species is now known to occur in 12 counties in the eastern half of the state ( Fig. 2D View Fig ) and is represented by 41 specimens, all but one collected by Lindgren funnels. Available label data indicate that some funnels were baited with either EtOH or a combination of EtOH and alpha-pinene. The earliest records are from 1990 from both Carter and Rosebud counties.

County Records ( Fig. 2D View Fig ): Big Horn (1), Carter (13), Dawson (3), Garfield (2), Golden Valley (1), Musselshell (1), Phillips (2), Powder River (4), Prairie (3), Rosebud (2), Treasure (7), Valley (2).

Additionally, during the course of identifying trogossitid specimens in 2020 for the C. P. Gillette Museum of Arthropod Diversity, Colorado State University, Fort Collins, Colorado, USA, the author discovered a specimen of T. collaris collected from Larimer County, Colorado which constitutes a new state record. The specimen was collected from P. ponderosa in 1996 (D. Leatherman, in litt.). A second Colorado specimen was collected approximately 128 km south southeast of the Larimer County record in Douglas County from a Colorado Department of Agriculture Lindgren funnel baited with UHR EtOH and omega-pinene (C. Harp, in litt.).
