03D85941E36DBB1EFF4F6D3BFFC9FB38.taxon	description	In the original description, Spix (1824) does not mention how many specimens he examined, and only one was illustrated (Spix 1824, plate VIII, figure 4; reproduced in Fig. 1 A). Peters (1872) mentions only one specimen (“ badly preserved and discolored ”) in his study about the amphibians collected by Spix deposited in the Zoologische Staatssammlung München. However, two syntypes were reported by subsequent authors (Cochran 1955; Duellman 1977; Glaw & Franzen 2006) — both syntypes are now apparently lost (Duellman 1977; Glaw & Franzen 2006). It is important to note that Hoogmoed and Gruber (1983) suggested that it is likely that Spix used only one specimen and the second one was included after the ZSM catalogue was produced (between 1872 and early twenty century). Peters (1872) considered Hyla cinerascens as a synonym of Hyla albomarginata, justifying that the examined syntype was “ a very poorly preserved copy of H. albomarginata Spix ”. Lutz (1951 a; b [1949]), however, considered unlikely that Spix’s species was conspecific with the Atlantic Forest species H. albomarginata, and therefore treated H. cinerascens as a distinct species. Furthermore, this synonymy was considered doubtful by several authors such as Duméril and Bibron (1841), Lutz (1951; 1973), Bokermann (1966).	en	Sturaro, Marcelo José, Costa, João Carlos Lopes, Maciel, Adriano O., Lima-Filho, Geraldo R., Rojas-Runjaic, Fernando J.

03D85941E36DBB1EFF4F6D3BFFC9FB38.taxon	description	Duellman (1974), in his taxonomic reassessment of several Neotropical hylids, once again reviewed the status of the taxa mentioned above. He designated one of the syntypes of H. granosa as lectotype (BMNH 1947.2.12.99, from Canelos, Pastaza, Ecuador). It is worth mentioning that Cochran & Goin (1970) restricted the type-locality of Hyla granosa to Demerara Falls, Guyana, without indicating a lectotype. Only one of Boulenger’s specimens was collected at that locality (BMNH 1947.2.12.93). However, Duellman (1974: 8) explicitly designated a lectotype (BMNH 1947.2.12.99), and consequently, the type-locality of H. granosa became Canelos, Ecuador. When reassessing the status of H. granosa gracilis, Duellman (1974) concurred with Rivero (1972) that the taxon was to be considered a synonym of H. granosa, and consequently neither a synonym of H. punctata (as suggested by Cochran & Goin 1970), nor a subspecies of H. granosa (as suggested by Lutz 1951 a; b [1949], 1973). The status of most species was reviewed again by Hoogmoed (1979). Based on morphological, ecological, and acoustical evidence, he removed Hyla ornatissima from the synonymy of Hyla granosa. Hoogmoed (1979) did not comment on the status of H. cinerascens. A few years later, Hoogmoed and Gruber (1983), in a systematic review of Spix’s material, considered that Hyla granosa Boulenger, 1882 was a junior synonym of Hyla cinerascens Spix, 1824 but made the following remark: “ As H. granosa is a well-established name (Hoogmoed, 1979) it seems undesirable to replace it by a name which for a long time has been considered a synonym of a superficially similar species and of which the type has been destroyed. We therefore will propose the International Commission on Zoological Nomenclature to suppress H. cinerascens Spix, 1824 in order to stabilize the nomenclature of this taxon ”. The formal petition to ICZN was never submitted and the name Hyla granosa continued to be widely used for another 20 years, until Barrio-Amorós (2004) and Frost et al. (2006) used the name Hyla cinerascens for the taxon until then known as H. granosa. The use of H. cinerascens was widely followed and the name has become the standard for what was once known as H. granosa. The status of the species treated above has remained unchanged, except for generic reallocations. Faivovich et al. (2005) placed them in Hypsiboas, and Dubois (2017) corrected the generic name to Boana (by implication). As per our interpretation of historical literature, Boana cinerascens (Spix, 1824) is a valid name, and Boana granosa (Boulenger, 1882) and Boana granosa gracilis (Melin, 1941) are junior synonyms of it. Three recent expeditions to the Rio Negro and Rio Solimões regions (State of Amazonas, Brazil) of Amazonia yielded important material that allowed us to revisit the taxonomic issues mentioned above.	en	Sturaro, Marcelo José, Costa, João Carlos Lopes, Maciel, Adriano O., Lima-Filho, Geraldo R., Rojas-Runjaic, Fernando J.

Calls from one adult male (MPEG 40290) from PNJ, Novo Airão, Amazonas, Brazil (02 ° 18 ’ 04 ” S, 62 ° 28 ’ 07 ” W) and one adult male (MPEG 40282, neotype) from Tefé, Amazonas, Brazil (Fig. 8). Specimens were calling perched 3 m above the ground near the edge of the river. The call of the PNJ specimens consists of one to two notes (mean duration of 0.034 s, SD = 0.0016) separated by short intervals (mean inter-note interval = 0.11 s). The advertisement call has a mean duration of 0.19 s (SD = 0.05) with an average dominant frequency of 1814 Hz (SD = 96.99), mean rise time of 0.095 s (SD = 0.026), and mean frequency bandwidth of 1616.96 Hz (SD = 17.25) (Fig. 8). The call from Tefé consists of two to three notes (mean duration of 0.037 s, SD = 0.0019) separated by short intervals (mean inter-note interval = 0.12 s). The advertisement call has a mean duration of 0.26 s (SD = 0.080) with an average dominant frequency of 1874 Hz (SD = 127.31), mean rise time of 0.13 s (SD = 0.041), and mean frequency bandwidth of 1762 Hz (SD = 17.09) According to Hoogmoed (1979), Crawford & Jones (1933), firstly described the call of Hyla granosa as a medium-pitched “ pink ”, however for him this call was more similar to that of H. punctata and for him, specimens of both species were confused. He provided sonograms of calls of both species from Suriname, without comments on temporal or spectral parameters. Later, the advertisement call of Hyla granosa was described by Duellman (1978) as a two- to four-note call, usually: “ boop-boop-boop ”. The duration of the notes was 0.078 seconds and the average dominant frequency was 1390 Hz. Subsequently, De la Riva et al. (1997) described the call as a series of two to seven short notes that decrease in intensity, with one average dominant frequency of 1327 Hz. Calls from studies in Ecuador (Pareja et al., unpublished) show values close to those found by Duellman and De la Riva et al.; the dominant frequency varies between 1560.41 Hz up to 1839.50 Hz. Boana cinerascens from the Guyanes has a call of 1 – 2 notes with a dominant frequency between 1260 – 2500 Hz (Lescure and Marty, 2000). The call of Boana cinerascens differs from the other advertisement calls of the group: Boana jimenezi´ s advertisement call is composed of 3 – 4 notes with a dominant frequency at 3010 – 3488 Hz., and Boana punctata calls with 5 – 15 notes and a dominant frequency between 689 – 1540 Hz (Hödl, 1977; Lescure and Marty, 2000; Marquez et al., 1993; Señaris and Ayarzaguëna, unpublished data). Finally, the mating call of Boana sibleszi usually consists of one note, occasionally two, with the dominant frequency at 1680 – 2231 Hz. Information regarding the advertisement calls of the Boana punctata group are summarized in Table 1.	en	Sturaro, Marcelo José, Costa, João Carlos Lopes, Maciel, Adriano O., Lima-Filho, Geraldo R., Rojas-Runjaic, Fernando J.

03D85941E361BB0AFF4F6F1CF81AFCC4.taxon	diagnosis	Diagnosis. Based on the molecular phylogenetic analysis, Boana gracilis should be considered a member of the B. punctata group. Boana gracilis is diagnosed morphologically by the following combination of characters: (1) medium sized Boana (SVL males 33.7 – 37.2, mean 35.9 mm, N = 26); (2) snout truncate in both dorsal and lateral views; (3) skin on dorsum granular; (4) forearm slightly hypertrophied; (5) prepollex small prepollical spine not protruding out of skin; (6) mental gland present; (7) number of vomerine teeth up to 10; (8) lacking small tubercles on postaxial side forearm and supernumerary tubercles on hand; (9) round subarticular tubercles on fingers I and IV, by not having supernumerary tubercles on hands; (10) in life, dorsum predominantly yellowish-green with large yellow blotches, scattered reddish-brown dots (melanophores) and reddish-brown irregular blotches within the white blotches (most of the examined specimens), a reddish-brown transversal interorbital bar (expanded on eyelid); (11) in preservative, dorsum cream with large white blotches and scattered brown small melanophores, and brown irregular blotches within the white blotches (most of the examined specimens); a brown transversal interorbital bar (expanded on eyelid); (12) dorsolateral stripe absent; (13) subgular, single vocal sac. Comparisons with congeners in the Boana punctata group. Because of the phylogenetic position of this taxon, we limit the comparisons to species in the B. punctata group. We made the comparisons by direct examination of preserved specimens, photographs (especially for color in life) and / or the literature. Character states for the species under comparison are given in parentheses. Boana gracilis differs from B. alemani in dorsal color pattern (in preservative: cream with dark spots; color in life unknown) and its larger size (SVL 30.5 mm). Boana gracilis differs from B. atlantica in dorsal color pattern (in preservative: white with yellow dorsolateral stripes and sparse spots; in life: green with reddish brown dorsolateral stripes and sparse spots) and its smaller size (male SVL> 37 mm) (examined specimens and Caramaschi & Velosa 1996; Haddad et al. 2013). Boana gracilis differs from B. cinerascens by its higher number of vomerine teeth (up to 10 vs. up to six in B. cinerascens), by lacking small tubercles on postaxial side forearm (present), and supernumerary tubercles on hand (present), dorsal color pattern (in preservative: cream with scattered, very small, white spots; in life: green, with sparse small white spots). Boana gracilis differs from B. hobbsi in dorsal color pattern (cream with few and sparse dark brown spots and two dorsolateral dark brown stripes) and its small size (holotype B. hobbsi SVL = 42.5 mm) (examined specimen, and Cochran & Goin 1970). It differs from B. picturata (Boulenger, 1899) in dorsal color pattern (in preservative: cream with reticulate violet blotches margined by purplish red) and much smaller size (SVL> 47 mm in all examined specimens). Boana gracilis differs from B. punctata in dorsal color pattern (in preservative: cream with sparse white spots and, in most individuals, dorsal lateral white and red stripes) (examined specimens and photo of the holotype provided in Milto & Barabanov 2011). It differs from B. sibleszi in dorsal color pattern (sexual dimorphism [Hoogmoed, 1979], in life: green speckled by white or brown, with or without yellow dorsolateral stripes; in preservative: cream speckled by brown and a transversal brown bar between eyes), mental gland (absent) (Cole et al. 2013; Hoogmoed, 1979; Kok & Kalamandeen 2008; Rivero 1972). Boana gracilis and B. sibleszi are not sister species in our phylogeny (Fig. 5). Boana gracilis differs from B. jimenezi by the shape of the subarticular tubercles on fingers I and IV (bifid), by not having supernumerary tubercles on hands (present), by the presence of a mental gland (absent) and dorsal color pattern (in life: pale green with numerous small tan or reddish-brown chromatophores, with or without dorsolateral white stripes; in preservative: cream with numerous small chromatophores, with or without immaculate white dorsolateral stripes) (Señaris & Ayarzagüena 2006).	en	Sturaro, Marcelo José, Costa, João Carlos Lopes, Maciel, Adriano O., Lima-Filho, Geraldo R., Rojas-Runjaic, Fernando J.
