Abstract

Tylobolus utahensis Chamberlin, the only representative of the genus occurring in the southwestern deserts, ranges from central Inyo County, California, to the western periphery of Kane County, Utah. This distribution roughly corresponds to the northern limit of the Mojave Desert ecosystem and is also shown by the milliped Piedolus utus Chamberlin (Spirobolida: Atopetholidae) and the centipede Theatops posticus (Say) (Scolopendromorpha: Cryptopidae). Tyhbolus fredericksoni Causey, ostensibly from Douglas County, Kansas, is designated a "nomen dubium" and disregarded pending collection of fresh material; Narceus gordanus (Chamberlin) is deleted from South Carolina and Tennessee. Tybbolus uncigerus (Wood) occurs north of the Columbia River in Klickitat County, Washington, and Hiltonius thebanus Chamberlin is referrable to Onychelus Cook in the family Atopetholidae.
