We present a list of 24 new blazar candidates selected in a search forpossible counterparts of spatial clusters of gamma-ray photons in the recent9Y-MST catalogue, at energies higher than 10 GeV and at Galactic latitudeshigher than 20 degrees. 13 of these clusters are also included the preliminaryrelease of the 4FGL catalogue of gamma-ray sources. The search for possiblecounterparts is based on the possible associations of the clusters with radiosources within a circle having a radius of 6 arcmin. We then investigated thepossible optical or mid-IR associations of these sources, checking if they showsome properties typical of new blazar candidates.
