Compared to other members of Bolitoglossa, B. aureogularis is moderate sized with a slender build. The snout-vent length of the holotype (48.8 mm) is almost equivalent to those of B. splendida (a geographic neighbor), B. pesrubra, B. subpalmata, and B. gomezi (all Talamancan species). It has a narrow head and relatively short, rounded snout with small nostrils; eyes are also small and do not extend beyond the margins of the head. Its nasolabial protuberances are not pronounced. It has moderate webbing on its hands and feet, more extensive on the latter, with well-differentiated digits (Boza-Oviedo et al. 2012).
Its coloration is seen in both adults and juveniles (Boza-Oviedo et al. 2012).

Life History, Abundance, Activity, and Special Behaviors
Based on mtDNA phylogenetic analysis, B. aureogularis is most closely related to B. robinsoni, which represents a previously unknown clade that is well supported and consists so far of only these two species, which are strikingly different in morphology and coloration. B. aureogularis occurs in the north and west of eastern Costa Rica while B. robinsoni to the south and east into western Panama (Boza-Oviedo et al. 2012). In contrast to the slender B. aureogularis, B. robinsoni, is robust and larger (45 - 63 mm) in snout-vent length, with large protruding eyes. B. robinsoni has yellow speckling throughout its dark body (Bolaños and Wake 2009).
