Mordellaria Ermisch, 1950

Mordellaria borealis (LeConte, 1862)

Adults were collected from a recently dead spruce ( Picea A. Dietr. ; Pinaceae ) tree in New York ( Felt 1906). This species was found breeding in maple ( Acer L.; Sapindaceae ) stumps in New York ( Felt 1906, 1924) and peach wood in Indiana (n = 2, Dolphin et al. 1972). Additionally, adults have emerged from loblolly pine logs, dead for six months to a year, in South Carolina (n = 1, Ulyshen and Hanula 2009; n = 6, M. D. Ulyshen, personal observation), new host record. Considering that this is a northern species ( Bright 1986; Downie and Arnett 1996), the record in South Carolina represents an extension of the known range and is a new state record.

Mordellaria serval (Say, 1835)

Two adults emerged from moderately decayed wood of hardwoods in Tennessee ( Ferro et al. 2012). Additionally, adults were collected on a cut jack pine ( Pinus banksiana Lamb. ) in Wisconsin (Lisberg and Young 2003b), ironwood (probably Carpinus L. or Ostrya Scop. ; both Betulaceae ) stumps and dead beech in Ontario ( Brimley 1951), and were beaten from dead branches of basswood ( Tilia L.; Malvaceae ) and hickory in Indiana (Downie and Arnett 1996).

Mordellaria undulata (Melsheimer, 1846)

This species was reported to emerge from elm ( Ulmus L.; Ulmaceae ) dead for more than three years ( Hoffmann 1942). Additionally, adults were beaten from dead hardwood branches in Indiana (Downie and Arnett 1996).
