Webster, coll. // Regenerating mixed forest, pitfall trap (1 ♂, RWC); same locality and collector but 45.8428°N , 66.7279°W , 14.IX.2004 // Mixed forest, small sedge marsh, in moist grass litter (1 ♂, 1 sex undetermined, RWC). Natural history. In NB, specimens were collected from a pitfall trap and from moist grass litter in a small sedge marsh in a mixed forest. One specimen from QC was captured in a Luminoc pit-light trap ( Klimaszewski et al. 2002 ); specimens from ON were collected in hedgerows beside soybean fields ( Brunke 2011 [thesis]). Little else is known about the biology of this species. Adults were found during May, June, and September. Distribution in Canada and Alaska. ON, QC, NB ( Klimaszewski et al. 2002 ; Majka and Klimaszewski 2008b ; Bousquet et al. 2013 ). Comments. Brunke et al. (2012) provided additional evidence supporting the concept that Tinotus caviceps and Tinotus trisecus Casey are distinct species. Figures 25-33.
