Comment

In the Scinax ruber clade, Scinax rostratus group of Faivovich, Haddad, Garcia, Frost, Campbell, and Wheeler, 2005, Bull. Am. Mus. Nat. Hist., 294: 96–97. This species was known as Ololygon egleri (Lutz, 1968, Pearce-Sellards Ser., 10: 8), until Hoogmoed and Gruber, 1983, Spixiana, München, Suppl., 9: 371, noted that Hyla nebulosa Spix, 1824, is the oldest name for this species. Duellman, 1997, Sci. Pap. Nat. Hist. Mus. Univ. Kansas, 2: 21, commented on a population in southeastern Venezuela.  Bolivian record by De la Riva, 1990, Boll. Mus. Reg. Sci. Nat. Torino, 8: 281. Without comment, considered a junior synonym of Hyla albopunctata by Lavilla, 1994 "1992", Acta Zool. Lilloana, 42: 70. See De la Riva, Márquez, and Bosch, 1994, Bijdr. Dierkd., 64: 75–85, for advertisement call. De la Riva, Köhler, Lötters, and Reichle, 2000, Rev. Esp. Herpetol., 14: 37, provided the Bolivian citation. Lescure and Marty, 2000, Collect. Patrimoines Nat., Paris, 45: 164–165, provided a photo and brief account for French Guiana. Fouquet, Gilles, Vences, Marty, Blanc, and Gemmell, 2007, PLoS One, 10 (e1109): 1–10, provided molecular evidence that this is a species complex. See account for Surinam population by Ouboter and Jairam, 2012, Amph. Suriname: 180–181. See Cole, Townsend, Reynolds, MacCulloch, and Lathrop, 2013, Proc. Biol. Soc. Washington, 125: 415–416, for brief account and records for Guyana. Zimmerman, 1983, Herpetologica, 39: 235–246, reported on advertisement call, as Hyla egleri. See Barrio-Amorós, Rojas-Runjaic, and Señaris, 2019, Amph. Rept. Conserv., 13 (1: e180): 86–87, for comments on range and literature. Señaris and Rojas-Runjaic, 2020, in Rull and Carnaval (eds.), Neotrop. Divers. Patterns Process.: 571–632, commented on range and conservation status in the Venezuelan Guayana. Dubeux, Silva, Nascimento, Gonçalves, and Mott, 2019, Rev. Nordestina Zool., 12: 18–52, summarized the literature on larval morphology. See Dubeux, Nascimento, Lima, Magalhães, Silva, Gonçalves, Almeida, Correia, Garda, Mesquita, Rossa-Feres, and Mott, 2020, Biota Neotrop., 20 (2: e20180718): 1–24, for characterization and identification of larvae north of the Rio São Francisco in the Atlantic Forest of northeastern Brazil.
