Cicindela formosa gibsoni Brown, 1940

Cicindela formosa gibsoni Brown, 1940b: 182. Type locality: "Great Sand Hills, west of Swift Current, Sask[atchewan]" (original citation). Holotype (♂) in CNC [# 4885]. Etymology. This subspecies was named after Arthur Gibson [1875-1959], Dominion entomologist with a special interest in Lepidoptera . Gibson had no formal training but learned under James Fletcher and Charles Gordon Hewitt, both with the Department of Agriculture in Ottawa.

Distribution.

This subspecies, also known as the “Gibson’s Sand Tiger Beetle", is known from southwestern Saskatchewan (Wallis 1961: 38; Gaumer 1977: 216) and northwestern Colorado (Kippenhan 1994: 41). The record from “Alberta” (Bousquet and Larochelle 1993: 55) is in error; that from "North Dakota" (Freitag 1999: 26) needs confirmation; that from “Utah” (Erwin and Pearson 2008: 136) is probably based on intergrades found along the Green River (see Pearson et al. 2006: 84).

Note.

In his unpublished thesis, Gaumer (1977: 219) treated the Colorado population of this subspecies as a distinct subspecies of Cicindela formosa . This subspecies intergrades narrowly with the formosa form on all sides of its small range in southern Saskatchewan and along the Green River in northeastern Utah (Pearson et al. 2006: 84).
