Diagnosis. This is a large uniformly purplish-black colored Bolitoglossa of the franklini species group (Stuart 1943), subgenus Magnadigita (Taylor 1944). We have assigned it to Bolitoglossa because it lacks a sublingual fold and to Magnadigita based on its reduced interdigital webbing, well-defined digits with broad tips, and its phylogenetic relationships according to molecular data. Molecular data shows that B. qeqom is the sister taxon of B. lincolni + B. franklini with high support (bootstrap proportion [BS] = 91, posterior probability [PP] = 1) with relatively large genetic distances from other members of this clade. Bolitoglossa qeqom differs from all other species of the sub-genus by its large adult size except from B. franklini Wake & Lynch 1982, B. lincolni Elias 1984, B. meliana Wake & Lynch 1982, B. omniumsanctorum Campbell et al. 2010 and B. tenebrosa Vásquez-Almazán & Rovito 2014. The new species differs from B. franklini, B. lincolni, B. meliana, B. tenebrosa, and B. tzultacaj Campbell et al. 2010 by having only one phalange free of webbing in digit III of feet and relatively longer legs with only one costal groove between adpressed limbs. Differs from B. franklini, B. lincolni, B. meliana, and B. tzultacaj (sub-adult) by having more maxillary + premaxillary teeth, and two phalanges free of webbing in digit III of hand. The new species can be distinguished from B. franklini, B. meliana, and B. tenebrosa by having fewer vomerine teeth, relatively shorter tail, and by having only one phalange free of webbing in digit III of feet.
