CSS selector for removing row hover background?

Which is the specific css selector to disable the hover background for the row on the gallery table?

I was able to disable the table cell's background with

div.view-node-gallery-gallery-item-views table.views-view-grid td:hover,
div.view-node-gallery-gallery-summaries table.views-view-grid td:hover

but an unable to identify the row. (...views-grid tr:hover was unsuccessful.)

Thanks in advance.
