A new bumblebee species from a single location in highland Guatemala is described based on a type series of 10 queens and 21 workers. B. xelajuensis is morphologically very close to B. trinominatus and seems also rare and restricted to a small area. Differences in colouring are obvious, however. Triangular graphing of several characters indicative of body proportions for queens of B. xelajuensis and B. trinominatus supports their being two seperate species.
