FIGURE 7 in A new species of Allobates (Anura: Aromobatidae) from the Tapajós River basin, Pará State, Brazil
FIGURE 7. Comparisons of advertisement calls of Allobates magnussoni with those of similar species by means of 5 s long oscillograms (upper graphs) and sonograms (lower graphs). (A) Continuous emission of single notes split by regular silent intervals, the most frequent call arrangement sampled for A. magnussoni at the species type locality in Parque Nacional da Amazônia (PNA), Pará State, Brazil (INPA-H 32962, 16.8 mm SVL, recorded at 24.4°C). (B) Emission of note-pairs split by regular silent intervals, an alternative call arrangement produced sporadically by a few males sampled in PNA and in Treviso, an additional location on the east bank of the Tapajós River (unvouchered male recorded in PNA at 24.5°C). (C) Call formed by the continuous emission of a single note, produced by a male recorded in Treviso (INPA-H 10108, 15.5 mm SVL, recorded at 23.0°C). Note similarity with calls presented in (A). (D) Advertisement calls of one Allobates flaviventris male recorded at Fazenda Experimental Catuaba, in Acre State (18.2 mm SVL, recorded at 25.0°C). Note shorter intervals between consecutive note-pairs and between notes in the same pair, when compared to those emitted by A. magnussoni (B). (E) and (F) Advertisement calls of two Allobates brunneus males recorded at the species type locality in Chapada dos Guimarães, Mato Grosso State. Notes produced continuously by A. brunneus (E) are shorter and emitted at higher frequency bandwidth when compared to those produced by A. magnussoni (A, B); the former also emits calls in short trills formed by 6–11 notes at air temperatures above 28°C (F). (G) Advertisement call of Allobates crombiei recorded at the species type locality at Cachoeira do Espelho, on the east bank of the Xingu River (17.6 mm SVL, recorded at 25.5°C). (H) Advertisement call of Allobates masniger recorded in PNA (18.2 mm SVL, recorded at 24.3°C) where it occurs syntopically with A. magnussoni.

FIGURE 11. Distribution of Allobates magnussoni and position of type localities of morphologically similar species in genus Allobates in northern South America. Yellow stars: (1) Allobates magnussoni's type locality, defined as Parque Nacional da Amazônia, on the left bank of the Tapajós River, south of the city of Itaituba, Pará State, Brazil.

White dots correspond to permanent sampling sites subject to anuran surveys both by our research group and by Programa de Pesquisa em Biodiversidade (detailed information on location of sampling sites and biological surveys available at http://ppbio.inpa.gov.br) where the new species has not been detected.
FIGURE 10 in A new species of Allobates (Anura: Aromobatidae) from the Tapajós River basin, Pará State, Brazil
FIGURE 10. Evolutionary relationships among Allobates magnussoni and other species of Allobates occurring in Brazil and across the Guiana Shield region, in northern Amazonia as inferred from an unrooted maximum likelihood phylogenetic tree based on a 481bp fragment of the 16S rDNA mitochondrial gene.

FIGURE 9 in A new species of nurse-frog (Aromobatidae, Allobates) from the Madeira River basin with a small geographic range
FIGURE 9. Waveforms (upper graphs) and sonograms (lower graphs) of advertisement calls of Allobates bacurau and three cryptically colored Allobates distributed in forests on the east bank of the middle and lower course of the Madeira River, Amazonas State, Brazil. In comparison with advertisement calls of A. bacurau, A. grillisimilis emits shorter (<0.5 s long) note trills; emission of notes by A. caeruleodactylus is continuous (i.e. notes are not arranged in discrete trills) and silent intervals between notes are longer than the ones in the calls of A. bacurau; A. masniger also emits notes continuously, but at a lower frequency bandwidth. Calls of A. grillisimilis, A. caeruleodactylus and A. masniger recorded in 2008 in Borba (04°26'03" S, 59°37'25" W), north of Manicoré.
