Trinominatus

Bombus trinominatus Dalla Torre modestus Smith, 1861:153, examined, not of Eversmann, 1852:134 (= B. modestus Eversmann) trinominatus Dalla Torre, 1890:139, replacement name for modestus Smith, 1861:153 xelajuensis Asperen de Boer, 1992b:162 3 names

TAXONOMIC STATUS: The description of B. xelajuensis shows that this nominal taxon, known from a single location, diverges only slightly in colour pattern and morphology from the otherwise restricted and uncommon mountain species B. trinominatus. Therefore it seems most likely to be conspecific with B. trinominatus, with a slightly different colour pattern. From COI barcodes, these taxa appear likely to be separate species. More evidence is awaited. DISTRIBUTION: S Nearctic Region.
