Madoniella dislocata (Say, 1825)

NOVA SCOTIA: 54 specimens examined from Antigonish, Cape Breton, Halifax, Kings, Pictou, and Queens counties. The earliest record is from 1962 (Kings Co.: Berwick, 28.viii.1962, H.T. Stultz, ACNS). PRINCE EDWARD ISLAND: Queens Co.: St. Patricks, 14.vii.2002, C.G. Majka, red spruce forest, CGMC.

Newly recorded in Nova Scotia and Prince Edward Island. Scattered records from across the region ( Figure 7 ) [Specimens of M. dislocata from NB were not available for examination; consequently they are not plotted on the distribution map.]. In Point Pleasant Park, Nova Scotia, found in association with the galleries of Scolytinae feeding on red spruce ( Picea rubens ) and white pine ( Pinus strobus ). The most abundant scolytines found in these galleries (75% of individuals) are Hylurgops rugipennis pinifex , Trypodendron lineatum , and Polygraphus rufipennis in spruce, and Ips pini , and Pityogenes hopkinsi in pine (C. Majka, unpublished data).

Associated with bark beetles in oak ( Quercus ), juniper ( Juniperus ), cedar ( Thuja ) ( Cupressaceae ), hickory ( Carya ), pine ( Pinus ), hackberry ( Celtis occidentalis L.)

( Ulmaceae ), black spruce ( Picea mariana (Mill.) BSP.), butternut ( Juglans cinerea L.) ( Juglandaceae ), redbud ( Cercis ) ( Brassicaceae ), and other hardwoods ( Opitz 2002). Knull (1951) reported it as predaceous on Anelaphus villosus (Fabricius) (Cerambycidae) , Bitoma carinata (LeConte) (Colydiidae) , Chramesus hicoriae LeConte (Curculionidae) , Hylocurus sp., Scolytus muticus Say , S. rugulosus Ratz. , Pityophthorus dentifrons Blackman , P. consimilis LeConte , and Polygraphus rufipennis (Kirby) (all Scolytinae ).
