We announce the discovery of a new low-mass , pre-main sequence eclipsing binary , MML 53 .
Previous observations of MML 53 found it to be a pre-main sequence spectroscopic multiple associated with the 15-22 Myr Upper Centaurus Lupus cluster .
We identify the object as an eclipsing binary for the first time through the analysis of multiple seasons of time series photometry from the SuperWASP transiting planet survey .
Re-analysis of a single archive spectrum shows MML 53 to be a spatially unresolved triple system of young stars which all exhibit significant lithium absorption .
Two of the components comprise an eclipsing binary with period , P = 2.097891 ( 6 ) \pm 0.000005 and mass ratio , q \sim 0.8 .
Here , we present the analysis of the discovery data .
