Type species. Dendrobates reticulatus Boulenger, 1884   “1883”

Proposed sister group. Andinobates   gen. nov.

Definition and diagnosis. Unambiguous synapomorphies include: 5 nuclear and 16 mitochondrial synapomorphies (based upon the dataset used in this study, Fig. 3 View FIGURE 3 , Tables 2 and 3); distinctive pale reticulation on limbs and venter present ( Fig. 2 View FIGURE 2 c-i and Fig. 2 View FIGURE 2 h-i). Secondary losses of this pale limb reticulation appear to have occurred in R. yavaricola   and R. summersi   , some morphs of R. fantastica   , R. imitator   and R. sirensis   . Other features include: adult SVL less than 21 mm; adults typically brightly colored, often with bright yellow, red, or green dorsal coloration (either uniform, spotted, or striped); dorsolateral stripe, if present, extending to top of thigh (vs. not reaching thigh in Andinobates   ), ventrolateral stripe and oblique lateral stripe present or absent; Distinctive, bright coloration on throat present (usually yellow, orange or red); dorsal skin texture nearly smooth to weakly granular; head narrower than body; teeth absent; vocal slits present in males; finger I greatly reduced and shorter than finger II; finger discs II–IV greatly expanded; in adults disc on finger III at least two times wider than distal end of adjacent phalanx; thenar tubercle conspicuous (commonly vestigial, occasionally absent); toe discs III–V moderately expanded; toe webbing absent; median lingual process absent; larval vent tube dextral; larval oral disc emarginated; larvae without medial gap in papillae on posterior labium (known in all species expect R. cyanovittata   and R. ventrimaculata   , Table 4); scansorial; adults use arboreal phytotelmata for reproduction and deposit eggs away from or at edge of water in phytotelmata (Table 6); tadpoles deposited individually, typically by male; small clutches (2– 6 eggs, Table 6); vertebrae 2 and 3 unfused (known in R. amazonica   , R. toraro   sp. nov., R. imitator   , R. variabilis   , R. vanzolinii   , R. fantastica   , R. reticulata   and R. sirensis   ).

Distribution. This genus occurs within Amazonian rainforests of Brazil (States: Acre, Amapá, Amazonas, Pará, Rondônia), Bolivia (Department: Pando), Colombia (Departments: Amazonas, Caquetá, Putumayo (tentative), Vaupés), Ecuador (Provinces: Morona-Santiago, Napo, Orellana, Pastaza, Sucumbíos), French Guiana (Arrondissements: Cayenne, Saint-Laurent-du-Maroni), Guyana (District: Potaro-Siparuni) and Peru (Departments 1: Amazonas, Cusco, Huánuco, Junín, Loreto, Madre de Dios, Pasco, San Martín, Ucayali). Species within this genus occur between sea level and 1600 m, Fig. 9 View FIGURE 9 .

Remarks. Our definition of Ranitomeya   is essentially equal to the definition of Caldwell & Myers (1990) ventrimaculatus   group. The genus apparently diverged from Andinobates   approximately 14 mya during the mid-Miocene ( Santos et al. 2009).
