Ceracis thoracicornis (Ziegler, 1845)

NOVA SCOTIA: Cumberland Co.: Amherst , 1.ii.1988, J. Ogden, bracket fungus, (7), NSNR ; Guysborough Co.: Malay Lake , 1.16. vii.1997, D.J. Bishop, red spruce forest, flight-intercept trap, NSMC ; Kings Co.: Wolfville , 1.ii.1988, J. Ogden, bracket fungus, JOC ; Kentville , 15.xi.2002, D.H. Webster, on Populus, DHWC .

Newly recorded in Nova Scotia and the Maritime Provinces as a whole ( Fig. 1 ). Orledge and Reynolds (2005) left it in the ungrouped category of ciids. It is one of most common, widespread, and polyphagous species of ciids in eastern North America . In the northern part of its range, and on various species of fungi, it is often found co-occurring with Cis horridulus , C. striolatus , C. fuscipes , C. pistoria , and Octotemnus laevis ( Lawrence 1967) .
