Results of new radar images obtained from the Arecibo Observatory for portions of the southern hemisphere of Venus are reported. The images show that the upland of Phoebe Region contains the southern extension of Devana Chasma, a rift zone extending 4200 km south from Theia Mons and interpreted as a zone of extension. Alpha Regio, the only large region of tesserae within the imaged area, is found to be similar to tesserae mapped elsewhere on the planet; it covers a smaller percentage of the surface than that observed in the northern high latitudes. Themis Region is mapped as an ovoid chain of radar-bright arcuate single- and double-ring structures, edifices, and bright lineaments. On the basis of the present analysis, the southern hemisphere of Venus is interpreted to be characterized by regions of mantle upwelling on a variety of scales, upwelling and extension, and localized compression.
