Discussion

Remarks. The larva named Pentaneurini sp. A and assumed to be A. (A.) basalis in Hamilton (1965) keys to A. (A.) aspera except that Hamilton gives an AR of 5.0– 5.7 while Roback (1985 Table 10) gives an AR of 4.5–5.2. A. (A.) aspera is listed in Roback (1985: 201) as present in Marion Lake.

Distribution

Distribution. The species is known from British Columbia to New Hampshire and south to Florida and California (Roback 1985: 201; Oliver et al.1990: 10; Hudson et al. 1990: 3; Spies 1999; Epler 2003, 2010; Caldwell 2009; Ashe & O’Connor 2009: 113).
