Narceus americanus (Beauvois, 1817)

Shelley, Rowland M. & Snyder, Bruce A., 2012, Millipeds from the eastern Dakotas and western Minnesota, USA, with an account of Pseudopolydesmus serratus (Say, 1821) (Polydesmida: Polydesmidae); first published records from six states and the District of Columbia, Insecta Mundi 2012 (239), pp. 1-17 : 4

Narceus americanus (Beauvois, 1817)

Published Record. Minnesota: Lyon Co., no further locality ( Shelley et al. 2006).

New Records. None.

Remarks. Aside from this record, Narceus has never been reported from Minnesota, although localities in Wisconsin and Iowa ( Keeton 1960; Watermolen 1995a, b; Shelley et al. 2006) indicate occurrence in the southeast along the Mississippi River. Shelley et al. (2006) thought that it might represent an allopatric population and suggested occurrence in the eastern fringe of South Dakota, which still seems plausible though we did not encounter the milliped. Gonopodal, cyphopodal, and somatic illustrations are available in Keeton (1960), Shelley (1978, 1988, 2002b), and Filka and Shelley (1980).
