Cis americanus Mannerheim, 1852

PRINCE EDWARD ISLAND: Queens Co.: St. Patricks , 16.vii.2002, C.G. Majka, Fomes fomentarius in coniferous forest, (4), CGMC .

Newly recorded in Prince Edward Island; previously recorded from New Brunswick and Nova Scotia ( Pielou & Verma 1968; McNamara 1991) ( Fig. 1 ). Lawrence (1971: 445) noted that, "This is an extremely variable, widespread, and polyphagous species, and it may represent a species complex." Specimens in the Maritime Provinces fall into the "typical northeastern" C. americanus geographic segregate with pronotum and elytra relatively dull, lateral pronotal margins narrower, elytral megapunctures smaller and less numerous than the micropunctures, vestiture denser, elytral bristles shorter, and size larger (corresponding to the synonymized Cis oweni (Hatch, 1962)) .
