The next use of the name was by LeConte and Horn (1876), who included with it a description and the species P. torpidus (LeConte) and P. aequalis (Horn). The name of this subgenus was thus made available by LeConte and Horn (1876). The subgenera Nomidus and Neopanscopus are both herein regarded as junior synonyms of Nocheles based upon their proposed phylogenetic relationships (Spanton 1992). Subgeneric Name. " Nocheles " is a Greek word meaning moving slowly, sluggish, in reference to the very slow-moving behavior of many Panscopus species as well as many other broad-nosed weevils. Diagnosis. Members of this subgenus are distinguished by the short scape not extending to the middle of the eye when next to head; five ventrites in females; and male apex of aedeagus slightly angular in shape with a slight medial acuity (Figs. 63–73). Included Species. Panscopus johnsoni, P. bakeri, P. longus, P. schwarzi, P. coloradensis, P. pallidus, P. ovalis, P. tricarinatus, P. bufo, P. abruptus, P. rugicollis, P. aequalis, and P. squamifrons.
