Holotype, allotype, and morphotype, National Museum of Natural History, Smithsonian Institution, Washington D.C. 115698, 115699, 1156700 (male I, female, male II); paratypes, National Museum of Natural History, Smithsonian Institution, Washington D.C., Department of Zoology, Tulane University, New Orleans, Louisiana.Type Locality
Conchas Reservoir, 32 miles (51.2 km) northwest of Tucumcari on State Route 104, San Miguel County, New Mexico.Range
"New Mexico, Texas, Arkansas, Oklahoma, Missouri, and Kansas" (Reimer, 1969:55). To this may be added southwestern Colorado.Remarks
As stated in an earlier checklist (Hobbs, 1974b) and elsewhere, this crayfish appears to be indistinguishable from Orconectes (G.) virilis (Hagen). Until the relationships of these two species and O. (G.) nais (Faxon) become more adequately understood, the conservative recognition of the three seems advisable. Particularly does this seem prudent in light of Unger's (1978) having presented evidence that the three taxa are perhaps distinct and that O. (G.) causeyi is more similar to O. (G.) nais than to O. (G.) virilis. Unfortunately, his samples were quite limited both in quantity and in representing the range of the complex.References
