Collection and habitat data. Adults were found in a mature hardwood forest with sugar maple ( Acer saccharum Marsh.), American beech ( Fagus grandifolia Ehrh.), white ash ( Fraxinus americana L.), and butternut ( Juglans cinerea L.), an old-growth northern hardwood forest with sugar maple and yellow birch ( Betula alleghaniensis Britt.), an old silver maple ( Acer saccharinum L.) swamp, an old-growth red pine forest, a mature red spruce ( Picea rubens Sarg.) forest, an old eastern white cedar ( Thuja occidentalis L.) swamp/forest, and old mixed forests. This species was captured in Lindgren funnel traps at all sites where these traps were used. Adults were also collected during an evening flight (between 15:00 and 18:00 h), and at an ultraviolet light. Adults were collected during April, May, June, July, and August. Distribution in Canada and Alaska. ON, QC, NB ( Campbell 1991a ). Casey (1898) used the number of antennal segments of the club to distinguish Sphindus trinifer ( three-segmented club) from Sphindus americanus (two-segmented club) in his key to the American Sphindus species. However, Downie and Arnett (1996) and Majka (2010) used size and other characteristics such as color to separate Sphindus americanus (1.5 to 2.5 mm in length) from Sphindus trinifer (1.7 mm in length). These characteristics are variable in these two species and are, therefore, unreliable for use in distinguishing these species. The specimens reported above all possess a three-segmented club, a character of Sphindus trinifer . The adults from New Brunswick are, on average, larger (ranging from 1.7 to 2.0 mm in length) than the 1.7 mm given for the type specimen of Sphindus trinifer (from Toronto, Canada) in Casey's original description. The specimens otherwise agree with the original description of Sphindus trinifer . Interestingly, Sphindus americanus was reported by Majka (2010) to be common and widespread in Nova Scotia. However, the specimen illustrated in his paper possesses a three-segmented club, a character of Sphindus trinifer . The Nova Scotia specimens should be re-examined to confirm their identity. Map 3.
