We are undertaking a survey to establish an upper limit on the space density of cataclysmic variables (CVs) and related objects in the solar neighborhood through a proper-motion based approach. We start with the new Lépine-Shara proper motion survey, which is sensitive down to 40 mas/yr, and select CV candidates from this using NUV - V colors from GALEX and V - K colors from 2MASS. In our first exploratory spectroscopic run, using the 2.4m Hiltner telescope at MDM Observatory, we identified a single new CV, LSPM 03338+3320 In this presentation we give details on this new CV. Briefly, its orbital period is near 96 minutes, its spectrum shows the double-peaked Balmer emission lines characteristic of quiescent dwarf novae, and its V magnitude is near 18.2.
