Type locality: "insula Sitkha [= Baranof Island, Alaska]" (original citation). Two syntypes in ZMH (Silfverberg 1987: 22) and MHNG (Marggi 2010: 186); a possible syntype in MCZ [# 5502]. Note. Lindroth (1963b: 287) designated a specimen in ZMH as lectotype but, according to Silfverberg (1987: 22), the specimen is not a syntype. In such case, the specimen loses its status of lectotype (ICZN 1999: Article 74.2). Distribution. This species is known from the Kenai Peninsula in Alaska (Lindroth 1963b: 288) south to northern Washington (Glesne et al. 2000: 89) and central Alberta (Maddison 1985: 113). All records prior to Lindroth (1963b) listed by Bousquet and Larochelle (1993: 132) need confirmation. Records. CAN : AB, BC (QCI, VCI) USA : AK, WA [CO, MT, NM, OR, UT, WY]
