Diplocheila obtusa (LeConte, 1847)

Rembus obtusus LeConte, 1847: 420. Type locality: «Longs’s Peak [Boulder County, Colorado]" (original citation). Three syntypes in MCZ [# 5706].

Diplocheila parallela Casey, 1920: 204. Type locality: "Homer [Champaign County], Illinois" (original citation). One syntype in USNM [# 47383]. Synonymy established by Lindroth (1954b: 136).

Distribution.

This species occurs from Cape Breton Island (Bousquet 1987d: 107) to south-central British Columbia, north to central Northwest Territories along the Mackenzie River (Lindroth 1969a: 948), south to eastern Washington, “Nevada” (Ball 1959: 82), the Sierra Blanca in south-central New Mexico (Fall and Cockerell 1907: 159), northwestern Texas (Oldham County, Foster F. Purrington pers. comm. 2010), “Missouri” (Ball 1959: 82), northwestern Tennessee (Stewart County, Foster F. Purrington pers. comm. 2010), and western Virginia (Hoffman et al. 2006: 24). The record from southern Louisiana (Summers 1874a: 80) is probably in error; that from “Arkansas” (Bousquet and Larochelle 1993: 209) needs confirmation.
