  We present 916 trigonometric parallaxes and proper motions of newly
discovered nearby stars from the United States Naval Observatory (USNO) Robotic
Astrometric Telescope (URAT). Observations were taken at the Cerro Tololo
Interamerican Observatory (CTIO) over a 2 year period from Oct 2015 to Oct 2017
covering the entire sky south of about +25 deg declination. SPM4 and UCAC4
early epoch catalog data were added to extend the temporal coverage for the
parallax and proper motion fit up to 48 years. Using these new URAT parallaxes,
optical and near-IR photometry from the APASS and 2MASS catalogs, we identify
possible new nearby dwarfs, young stars, low-metallicity subdwarfs and white
dwarfs. Comparison to known trigonometric parallaxes show a high quality of the
URAT-based results confirming the error in parallax of the URAT south
parallaxes reported here to be between 2 and 13 mas. We also include additional
729 trigonometric parallaxes from the URAT north 25 pc sample published in
Finch & Zacharias (2016) here after applying the same criterion as for the
southern sample to have a complete URAT 25 pc sample presented in this paper.
