<paragraph pageId="0" pageNumber="1">The distiphallus of the eastern material examined here (Maryland male illustrated) deviates slightly from that of the holotype, being more sinuate with the apex angled ventrally, not with a relatively elongate, straight middle section and a distally pointing apex. The male from Colorado identified by Spencer illustrates an intermediate shape, suggesting that there is a continuum of morphology, although this variation should be re-examined following the collection of more material.</paragraph>
