Background information. For a summary of current knowledge on this species see Brown et al. (2008c), with the exception of the following comments. Recently, E. Twomey rediscovered a population of R. fantastica   that exactly matched Boulenger’s description (identical to 3 of 4 types, Fig 15e View FIGURE 15 ) less than 20 km from Boulenger’s stated type locality. Two other populations of R. fantastica   are known to occasionally lack black crown markings (near Varadero, Loreto and near Yumbatos, San Martin), however both populations bear subtle differences and occur further from the presumed type locality (ca. 40 km NW and 55 km SW, respectively).

In 2008, Karl-Heinz Jungfer discovered a new population of this species in the Cordillera Campanquis near the Pongo de Manseriche, Loreto, Peru. Given its unique morphology and apparently disjunct distribution, we originally suspected that these frogs might represent an undescribed species. However, after performing phylogenetic analyses on sequences collected from these individuals, there is little phylogenetic support for this hypothesis and they appear to simply represent a northern population of R. fantastica   . Ironically, the discovery of this population (which is morphologically similar in appearance to R. summersi   ), further supports the classification of R. summersi   as a separate species from R. fantastica   . Based on our phylogeny, a population of R. fantastica   that occurs less than 30 km from a population of R. summersi   is most closely related to a population of R. fantastica   from Pongo de Manseriche. These two populations of R. fantastica   are separated by more than 250 km and several mountain ranges, versus less than 30 km and relatively contiguous habitat. This relationship could also be attributed to incomplete lineage sorting and should be further investigated.

The phylogenetic topology of R. fantastica   , R. summersi   and R. benedicta   differs from that published in Brown et al. (2008c). In this study, the lower Huallaga populations of R. fantastica   are sister to R. summersi   , which form a clade that is sister to R. benedicta   ; this entire clade is sister to the rest of the members of R. fantastica   . In Brown et al. (2008c), R. summersi   was sister to R. fantastica   (in which, R. fantastica   consisted of two main clades, one containing individuals from the lower Huallaga and an individual from Tarapoto and all individuals from lower Huallaga sister to all other R. fantastica   ) and both species were sister to R. benedicta   . To clarify these differences, we performed reciprocal topology tests (using Shimodaira-Hasegawa tests, Table 3); each study’s topology was tested on both datasets (note: samples not included in both analyses were left as they were in the unconstrained topology as much as possible). When using the current dataset, which contains fewer base pairs than Brown et al. (2008c), we found no statistical differences in either topologies (p = 0.491) suggesting they are equally probable. The differences in tree length (under Parsimony) were 1. However when using the dataset from Brown et al. (2008c), the Shimodaira–Hasegawa test rejected the topology observed in this study (p = 0.012), supporting the specific relationships observed in Brown et al. (2008c), with individuals from lower Huallaga being members of R. fantastica   ). The difference in tree lengths (via Parsimony) between these two tree topologies was 13. Thus, despite the topology of our phylogeny, we maintain that R. benedicta   is sister to a clade containing the sister species R. fantastica   and R. summersi   .

Even though these results support the specific status of the lower Huallaga individuals as R. fantastica   ( Brown et al. 2008c; Fig. 15 View FIGURE 15 ), this population’s phylogenetic status (and specific status) is not entirely clear. In other unpublished analyses (based on different datasets), these populations were observed sister to R. summersi   (as in this study), and based on morphology we cannot reject this possible relationship (that these populations are members of R. summersi   ). To clarify this, additional morphological and sequence data are necessary, using both mitochondrial and nuclear genes, and molecular data should be analyzed using coalescent-based phylogenies.

Distribution. This species is known to occur within the departments of Amazonas, Loreto and San Martín, Peru ( Fig. 20 View FIGURE 20 ).
