This species is very similar to Bolitoglossa occidentalis and B. rufescens and is differentiated from them by having shorter limbs. These three belong to the subgenus Nanotriton, which differs from other Bolitoglossa subgenera by having a combination of a small size, a relatively short tail, fully webbed feet, and a shorter rounded third digit of their hand (Campbell et al. 2010).
The dorsal side of the species ranges from tan to reddish brown. The ventral side can either be cream in color with darker melanophores scattered along its surface to almost completely dark, though not as dark as the flanks (Campbell et al. 2010).
Distribution and Habitat
Country distribution from AmphibiaWeb's database: Belize, Guatemala, Honduras
Life History, Abundance, Activity, and Special Behaviors
As mentioned above, B. nympha is found within the forests of Honduras, Guatemala, and Belize, where moisture and plant cover are abundant (Anderson et al. 1999). They are commonly found on the leaves of banana trees less than a meter off the ground or under decaying plants and logs. They are also commonly found when they emerge after rain showers or during misty nights (Campbell et al. 2010).
Individuals from the genus Bolitoglossa are typically insectivorous and have diverse diets as generalists. Prey includes ants, beetles, grasshoppers, or arachnids (Anderson et al. 1999).
Many Bolitoglossine plethodontids, such as B. nympha’s close relative B. occidentalis, display a unique behavior called tongue projection. This mechanism enables the rapid-fire of their “mushroom-shaped” tongues to target their prey (Wake et al. 2000). Additional research is necessary, however, to confirm B. nympha has this mechanism.
Like other plethodontids, B. nympha has nasolabial grooves that assist in chemoreception. Pheromones and chemical signals produced by these salamanders are influential in their social behavior. While under-studied, chemoreception has the capability to identify conspecifics, attract mates during courtship rituals, and mark territory (Jaegar et al. 1993).
Little is known about the life history and reproduction of B. nympha. Based on current phylogenetic data, direct development has evolved numerous times within Plethodontidae and is found within all the species of tribe Bolitoglossini. The majority of the subgenera Bolitoglossa exhibit direct development, meaning they are oviparous, and instead of having a free-living larval stage, individuals hatch as adults after embryogenesis (Wake et al. 1996). With this phylogenetic evidence, B. nympha may be characterized similarly, but more research is needed.
An individual of the subgenus Nanotriton believed to be B. nympha was observed using its tail to assist in climbing after falling from its perch. After falling, the individual was able to use its tail to grab on to a stem and pull itself up. This mechanism could assist in preventing injuries from falling and potentially help the species escape predation (Brown 2020).
Trends and Threats
Possible reasons for amphibian decline
General habitat alteration and loss
Bayesian Inference on the mitochondrial DNA 12S ribosomal subunit gene placed B. nympha as a sister group to both the Nanotriton subgenera, which includes B occidentalis and B. rufescens, and the Mayamandra subgenera, which includes B. hartwegi, B. stuarti, and B. xibalba(Campbell et al. 2010). Another Bayesian analysis of mitochondrial DNA of 16S and cytb genes placed B. nympha as a sister taxon to B. rufescens with B. occidentalis as the next most closely related species (Rovito et al. 2012).
The species epithet, “nympha”, comes from the Latin word “nympha”, which ascribes to a female spirit that lives in the forest or woods (Campbell et al. 2010).
