In the paper [The minimal Lapacian spectral radius of trees with a given diameter, Theoretical Computer Science 410: 78-83], Liu, Lu and Shu (2009) determine the trees with minimal Lapacian spectral radii for the diameter belongs to {1, 2, 3, 4, n - 3, n - 2, n - 1}, respectively. This paper gives the unique graph with minimal signless Lapacian spectral radius among graphs with diameter n - 4. Furthermore as a corollary, we determine the tree with minimal Lapacian spectral radius among trees with diameter n - 4.
