Blue straggler stars are exotic objects present in all stellar environmentswhose nature and formation channels are still partially unclear. They seem tobe particularly abundant in open clusters (OCs), thus offering a unique chanceto tackle these problems statistically.We aim to build up a new and homogeneouscatalogue of blue straggler stars (BSS) in Galactic OCs using Gaia to provide amore solid assessment of the membership of these stars. We also aim to explorepossible relationships of the straggler abundance with the parent cluster'sstructural and dynamical parameters. As a by-product, we also search forpossible yellow straggler stars (YSS), which are believed to be stragglers in amore advanced evolution stage. We employed photometry, proper motions, andparallaxes extracted from Gaia DR2 for 408 Galactic star clusters and searchedfor stragglers within them after performing a careful membership analysis. Thenumber of BBS emerging from our more stringent, selection criteria turns out tobe significantly smaller than in previous versions of this catalogue. OCs aretherefore not a preferable environment for these kinds of stars anymore. Inaddition, we found that BSS start to appear in clusters with ages larger thanlog(t) ~ 8.7 and are therefore absent in very young star clusters.The presentcatalogue supersedes the previous ones in several ways: membership assessment,number of stragglers found, and so forth. The new list includes 897 BSS and 77YSS candidates in 408 OCs. We expect this catalogue to be the basis for a newround of studies of BSS and YSS.
