Bipersona hottesi Knowlton & Smith 1936 = Eomacrosiphum nigromaculosum (Mac­ Dougall 1926)

E. nigromaculosum is a very distinctive species occurring on stems of wild and cultivated Rosa spp. in western N America. Apterae are bright red with black dorsal abdominal bands or patches, black SIPH held at right­angle to body, and black and yellow legs. We can find no significant differences between this species and the description of Bipersona hottesi, found on wild Rosa in Utah, other than the twisted cauda of the latter, so assume that this was an artefact of the mounting process.
