Amerizus oblongulus (Mannerheim, 1852)

Trechus oblongulus Mannerheim, 1852: 299. Type locality: "insula Sitkha [= Baranof Island, Alaska]" (original citation). Lectotype (♂), designated by Lindroth (1963b: 404), in MCZ [# 5560].

Amerizus crassicornis Casey, 1918: 165. Type locality: "Inverness [probably Inverness Passage], British Columbia" (original citation). Lectotype (♂), designated by Lindroth (1975: 122), in USNM [# 46899]. Synonymy established by Lindroth (1963b: 404).

Amerizus keeni Casey, 1918: 166. Type locality: "Metlakatla, British Columbia" (original citation). Lectotype (♂), designated by Lindroth (1975: 122), in USNM [# 46901]. Synonymy established by Lindroth (1963b: 404). Etymology. The specific name was proposed for the English clergyman John Henry Keen [1851 (or early 1852)-1950]. Keen was sent as missionary to the Haida Indian on the Queen Charlotte Islands for eight years (1890-1898) and a year later to Metlakatla, an Indian village a few miles northwest of Prince Rupert in British Columbia, for fourteen years. During those years, Keen collected extensively in the province and sent specimens to many museums and individuals, including Casey.

Distribution.

This species ranges from the Kenai Peninsula in Alaska (Lindroth 1963b: 405) south to “California” (Hayward 1897: 131) and to the Sangre de Cristo Mountains in northeastern New Mexico (Ball 1966b: 30). The record from “Mexico” (Hayward 1897: 131) is probably in error.
