Scaphinotus angusticollis (Mannerheim, 1823)

Cychrus angusticollis Mannerheim [in Fischer von Waldheim], 1823: plate 46. Type locality: "insula Unalaschka [Alaska]" (Fischer von Waldheim 1824: 47), which according to Van Dyke (1944: 4) and Lindroth (1961a: 21) is likely incorrect; "Sitka [Baranof Island, Alaska]" selected by Van Dyke (1944: 4). Syntype(s) in ZILR, ZMH (Lindroth 1961a: 21), and SMTD ( Grämer 1960: 101). Note. This name is credited to Fischer von Waldheim by some authors (e.g., Bousquet and Larochelle 1993: 83). However, Fischer von Waldheim’s statement (1824: 47) "le Cychrus d’Ounalaschka [i.e. Cychrus angusticollis ] dont je dois la description exacte et un dessin élégant et fidèle à Mr. Le Comte Mannerheim" clearly points to Mannerheim as the author.

Pemphus angusticollis var. nigripennis Roeschke, 1907a: 167. Type locality: "Gualala, Mendocino Co[unty], Cal[ifornien]" (holotype label). Holotype (♂) in ZMUA (Boer 2002: 84). Synonymy established by Gidaspow (1973: 66).

Scaphinotus angusticollis olympiae Van Dyke, 1944: 5. Type locality: "Sol Duc Hot Springs [Clallam County], Olympic Peninsula, Wash[ington]" (original citation). Holotype (♂) in CAS [# 5343]. Synonymy established by Lindroth (1961a: 21).

Distribution.

This species ranges from Kodiak Island in the Gulf of Alaska to northwestern California, east at least to eastern British Columbia [see Gidaspow 1973: Fig. 2]. The record from Torrington, Alberta (Gidaspow 1973: 68) is probably based on a mislabeled specimen.
