Background information. For a summary of knowledge on this species see Brown et al. (2008c). An individual from near Chazuta (the locality of some of the paratypes) was included in this study’s phylogeny. The results support the classification of this population based on morphology as R. summersi ( Brown et al. 2008c) . See R. fantastica account for discussion of this study’s phylogenetic results and the results of Brown et al. (2008c).

Distribution. This species in known to occur within a small area of San Martín, Peru ( Fig. 19 ).

FIGURE 3. A consensus Bayesian phylogeny based on 1011 base pairs of aligned mitochondrial DNA sequences of the 12S (12s rRNA), 16S (16s rRNA) and cytb (cytochrome-b gene) regions. Thickened branches represent nodes with posterior probabilities 90 and greater, other values are shown on nodes. Taxon labels depict current specific epithet, number in tree, the epithet being used prior to this revision (contained in parentheses), and the collection locality. A. Top segment. B. Middle segment. C. Bottom segment of phylogeny.

FIGURE 4. Putative species tree for Andinobates, Excidobates, and Ranitomeya. Placement of species where molecular data were lacking (A. altobueyensis, A. viridis, A. abditus, A. daleswansoni and R. opisthomelas) was based on morphology. Andinobates altobueyensis and A. viridis were placed as sister taxa due to the absence of dark pigmentation on dorsal body and limbs and overall similar dorsal coloration and patterning. These species were placed as sister to A. fulguritus (sequenced) on the basis of similar dorsal coloration (bright green to greenish-yellow). Andinobates opisthomelas was placed in the bombetes group in a polytomy with A. bombetes and A. virolinensis (both sequenced) due to their similar advertisement calls and morphology, particularly their red dorsal pattern and marbled venter. Andinobates daleswansoni was placed as sister to A. dorisswansonae due to the absence of a well-defined first toe in both species. Andinobates abditus was placed in the bombetes group based on a larval synapomorphy which appears to be diagnostic of that group (wide medial gap in the papillae on the posterior labium). However, A. abditus was placed as the sister species to all other members of the bombetes group due to the absence of bright dorsal coloration and isolated geographic distribution. Andinobates abditus is currently the only species of its genus known to occur in the east-Andean versant, thus its placement remains speculative until molecular data become available.
