We report the discovery of a young massive stellar cluster and infrared nebula in the direction of the CS molecular cloud associated to the IRAS point source 16132-5039 .
The analysis of the mid-infrared images from the more accurate MSX catalog , reveled that there are two independent components associated with the IRAS source .
The integral of the spectral energy distribution for these components , between 8.28 \mu m and 100 \mu m , gave lower limits for the bolometric luminosity of the embedded objects of 8.7 \times 10 ^ { 4 } L _ { \odot } 
and 9 \times 10 ^ { 3 } L _ { \odot } , which corresponds to ZAMS O8 and B0.5 stars , respectively .
The number of Lyman continuum photons expected from the stars that lie along the reddening line for early-type stars is about 1.7 \times 
10 ^ { 49 } s ^ { -1 } , enough to produce the detected flux densities at 5 GHz .
The NIR spectrum of the nebula increases with frequency , implying that free-free emission can not be the main source of the extended luminosity , from which we conclude that the observed emission must be mainly dust scattered light .
A comparison of the cluster described in this paper with the young stellar cluster associated with the IRAS source 16177-5018 , which is located at the same distance and direction , shows that the mean visual absorption of the newly discovered cluster is about 10 magnitudes smaller and it contains less massive stars , suggesting that it was formed from a less massive molecular cloud .
