We present two new massive clusters, discovered during the second phase of our MASGOMAS project (MAssive Stars in Galactic Obscured MAssive clusterS). The second phase of the project focuses on a systematic search of OB-type star candidates over-densities. We also present new near-infrared photometry (J, H, and K_S) and mid-resolution follow-up spectroscopy (H and K), obtained with LIRIS at ORM (La Palma), for the stellar content of the new massive clusters. With these data we have confirmed that Masgomas-1, the first candidate discovered by us, is a young and massive cluster, probably exceeding 10^4 {M}_{&sun;}, which hosts both an OB-type and an RSG populations. We have also determined the cluster distance and extinction, placing it in the Scutum-Centaurus arm, but far from the arm base (where RSGC1, RSGC2, RSGC3, Alicante 8 and Alicante 10 clusters are located), and closer to the Sun. For our second new massive cluster candidate (Masgomas-4), we have spectroscopically confirmed the presence of a massive stellar population, and photometrically detected a group of massive pre-stellar objects (Herbig Ae/Be candidates). With the estimated individual distances for the cluster massive stars, we have derived a single distance for both cores, confirming that Masgomas-4 is a single young cluster.
