(Andaraí/BA): Duarte et al. 2010; Andrade et al. 2016 Pseudopaludicola sp. 1 (Andaraí/BA): Veiga-Menoncello et al. 2014 Holotype. Adult male (ZUEC 23521; Figures 2–3, call voucher) collected by F.S. Andrade and A.A. Giaretta in Andaraí (12°48’22.28” S, 41°19’59.47” W, 416 m a.s.l.), Chapada Diamantina, state of Bahia, Brazil on 26 November 2016. Paratypes. Thirteen adult males: ZUEC 23512–3, 23515, 23518–20, 23522, 23524–5, 23527–30; and five adult females: ZUEC 23514, 23516–7, 23523, and 23526, all collected with the holotype. Seven specimens: UFMG 4310–6, collected at Área de Proteção Ambiental Marimbus-Iraquara, Andaraí, state of Bahia, Brazil (12°45’46” S, 41°17’48’’ W, 326 m a.s.l.; ca. 6 km from the type locality) on 26 January 2010 by F. S. F. Leite. Additional specimens: Brazil: state of Bahia: municipality of Mutuípe: CFBH 29652 (adult male); state of Minas Gerais: municipality of Nanuque: CFBH 33235 (adult female). Diagnosis. Pseudopaludicola florencei sp. nov. is assigned to the genus Pseudopaludicola by having a hypertrophied antebrachial tubercle (see Lynch 1989, Lobo 1995). The new species is characterized by the following combination of characters: (1) small size (SVL 12.8–14.8 mm in adult males); (2) upper eyelids smooth, with no palpebral tubercles; (3) heel smooth, with no enlarged conical tubercle; (4) relatively short hindlimbs (tibiotarsal articulation just reaching the posterior margin of eye); (5) 11 pairs of chromosomes (2n=22; see Duarte et al. 2010); and (6) advertisement call composed of regular series of three-pulsed notes, emitted at high rate. Comparison with other species. Pseudopaludicola florencei sp. nov. is promptly diagnosed from the P. pusilla species group (see Lynch 1989), which includes P. boliviana Parker, P. ceratophyes Rivero and Serna, P. llanera Lynch, P. pusilla (Ruthven), and P. motorzinho Pansonato, Veiga-Menoncello, Mudrek, Jansen, Recco- Pimentel, Martins, and Strüssmann by its terminal phalanges knobbed; whereas the abovementioned species have T-shaped terminal phalanges or expanded toe tips (disks or pads). The tips of the phalanges of the new species are similar in shape to those of P. falcipes (Figure 2B in Cardozo & Suárez 2012). The new species is also distinguished from P. ceratophyes by having upper eyelids smooth; P. ceratophyes has upper eyelids with an enlarged palpebral tubercle (Lynch 1989). Pseudopaludicola florencei sp. nov. differs from P. boliviana and P. motorzinho also by the heel smooth, with no enlarged, conical tubercle on the heel (Pansonato et al. 2016). Pseudopaludicola florencei sp. nov. is distinguished from P. saltica (Cope), P. murundu Toledo, Siqueira, Duarte, Veiga-Menoncello, Recco-Pimentel, and Haddad, and P. jaredi Andrade, Magalhães, Nunes-de-Almeida, Veiga-Menoncello, Santana, Garda, Loebmann, Recco-Pimentel, Giaretta, and Toledo (P. saltica species group) by having relatively short hindlimbs; i.e., the tibiotarsal articulation reaches the posterior margins of eye in the new species, whereas it reaches the tip of the snout in the P. saltica species group. The chromosome number 2n = 22 distinguishes Pseudopaludicola florencei sp. nov. (as Pseudopaludicola sp. in Duarte et al. 2010) from P. mystacalis (Cope) (2n = 16); P. canga Giaretta and Kokubum, P. facureae Andrade and Carvalho, and P. atragula Pansonato, Mudrek, Veiga-Menoncello, Rossa-Feres, Martins, and Strüssmann (2n = 18); P. ternetzi Miranda-Ribeiro and P. ameghini (Cope) (2n = 20) (Duarte et al. 2010; Fávero et al. 2011; Cardozo et al. 2016). In addition, Duarte et al. (2010) highlighted that P. florencei sp. nov. has morphological polymorphisms in the chromosomes 7, 8, and 11, which distinguishes it from P. mineira. Moreover, these same authors stated that the two species are distinguished by polymorphisms in the heterochromatin distribution and by the NOR position in the pair 8, which was terminal in P. mineira and subterminal in P. florencei sp. nov.. Pseudopaludicola florencei sp. nov. is promptly distinguished from P. canga (Giaretta & Kokubum 2003; Pansonato et al. 2012; Carvalho et al. 2015a), P. giarettai Carvalho (Carvalho 2012; Carvalho et al. 2015b), P. hyleaustralis Pansonato, Morais, Ávila, Kawashita-Ribeiro, Strüssmann, and Martins (Pansonato et al. 2012), P. facureae (Andrade & Carvalho 2013; Carvalho et al. 2015a), and P. parnaiba Roberto, Cardozo, and Ávila (Roberto et al. 2013; Carvalho et al. 2015a) by possessing pulsed notes, whereas those species have calls composed of non-pulsed notes. Note structure (three non-concatenated pulses) distinguishes P. florencei sp. nov. from species with notes with concatenated pulses (= lack of interpulse interval; sensu Magalhães et al. 2014): P. mystacalis [12– 14 concatenated pulses; Pansonato et al. 2013], P. boliviana [3–6; Duré et al. 2004], P. ibisoroca Pansonato, Veiga- Menoncello, Mudrek, Jansen, Recco-Pimentel, Martins, and Strüssmann [3–12; Pansonato et al. 2016], and P. motorzinho [2–6; Pansonato et al. 2016]. The new species is distinguished from other congeners [values within square brackets] with notes with nonconcatenated pulses by the following acoustic traits: P. ternetzi has shorter note duration (108–166 [32–80] ms) and interpulse interval (22–92 [1–14] ms), higher note (223–297 [606–921] notes per minute) and pulse rates (18–32 [61–139] pulses per second), and lower peak of dominant frequency (4608–5599 [3516–4500] Hz) (Andrade et al. 2017b); P. ameghini has shorter interpulse interval [1–23 ms], and higher note [348–452 notes per minute] and pulse rates [40–56 pulses per second], and lower peak of dominant frequency [3141–4312 Hz] (Andrade et al. 2017b); P. atragula has longer note duration [300–700 ms], higher number of pulses per note (3–4 [9–36]), lower note rate [42–98 notes per minute], and lower peak of dominant frequency [3618–4264 Hz] (Pansonato et al. 2014). The three species of the P. saltica species group (P. saltica, P. murundu, and P. jaredi) vary highly the number of pulses in their notes (2–7, combined values; Andrade et al. 2016); on the other hand, the new species has very stereotyped three-pulsed notes (Figure 4A). Pseudopaludicola falcipes may have notes with two or three pulses, but those with two pulses are more common (83 %, n = 240 analyzed notes; Figure 4D). In addition, the new species can be significantly differentiated from P. falcipes by having longer note duration and interpulse interval, and lower pulse and note rates (Wilcoxon-Mann-Whitney Test: P P. mineira by having stereotyped three-pulsed notes (only two notes of an individual have four pulses; n = 320 analyzed notes), whereas the P. mineira has stereotyped two-pulsed notes (Figure 4C). This character and its longer note duration (108–166 [42–87] ms) distinguish the new species from P. mineira (Pereira & Nascimento 2004; present study). Pseudopaludicola pocoto has also stereotyped three-pulsed notes (Figure 4B); however, P. florencei sp. nov. is readily distinguished from P. pocoto by having a higher note rate (223–297 [100–184] notes per minute). Additionally, P. florencei sp. nov. differs significantly from P. mineira by its note rate; and from P. pocoto by having shorter note duration, internote interval and interpulse interval, and higher pulse rate (Exact Wilcoxon- Mann-Whitney Test: P P. florencei sp. nov. is larger than P. pocoto, and smaller than P. mineira and P. falcipes (P P. florencei sp. nov. and its closer related species (P. mineira + P. pocoto) and P. falcipes, with all its individuals classified correctly (Table 3). The DAPC also revealed substantial differentiation among the new species and its closer related species (Figure 5B), with a greater separation along axis 1 (LD1 = 78.6 %; LD2 = 19.4 %). Number of pulses per note (66 %), pulse (12 %), and note (12 %) rates mainly accounted for species separation along LD1 (Figure 5B). Number of pulses per note (44 %), internote (27 %), and interpulse (18 %) intervals mainly accounted for species separation along LD2 (Figure 5B). See also the similar results presented in the performed PCAs (Appendix 4). Description of the holotype: Body elliptic and broad (Figure 2A–B; Table 1). Head elliptical, slightly wider than long.

Ventral surface pigmented (with small black dots scattered) on throat, chest, and belly (ZUEC 23512–3, 23515–8, 23520, 23522–3, 23525–8, 23530). The specimen ZUEC 23520 has a brown vertebral line, and the specimens ZUEC 23512, 23514, and 23520 have white scattered blotches on dorsum. The specimens ZUEC 23512–4, 23516–7, 23519, 23521–5, 23528, and 23530 do not have dorsolateral stains on body, from posterior corner of eyes to the region of insertion of legs. The specimens ZUEC 23514, 23523–4, and 23529– 30 have a discrete tympanic ridge from behind the eyes to the proximal portion of the arms. The specimens ZUEC 23525–8 have white blotches on the region between the mouth corner and the insertion of the arms. The specimen ZUEC 23512 has a large black blotch on dorsum. The specimen ZUEC 23527 has two large black blotches in the posterior portion of the dorsum, slightly above the cloacal region. Females have a more robust body and no nuptial pads, vocal sac and vocal slits. Vocalizations. Pseudopaludicola florencei sp. nov. emits an advertisement call of variable duration that can be long (1.6– 22.4 s), consisting of series of three-pulsed notes (1–5 series of three-pulsed notes per call) that lasts 0.4– 22.4 s, separated by intervals of 103–561 ms (Figure 4A). Notes last 108–166 ms separated by intervals of 64–141 ms, and are released at a rate of 223–297 notes per minute; notes have a slightly increase in amplitude from the first to the second pulses (= midpoint of note), followed by a decrease in amplitude regarding the second and third pulses (see oscillogram in Figure 4A). Notes are composed of three non-concatenated pulses (Figure 4A); notes with four pulses were rarely found (only two notes of an individual). Pulses vary from 4–16 ms, separated by intervals of 22–92 ms, and are released at a rate of 18–32 pulses per second (Figure 4A). Dominant (= fundamental) frequency peaks are between 4608–5599 Hz; minimum frequency ranges 4005–5125 Hz, and the maximum frequency ranges 4996–6804 Hz. Notes present up to two harmonics; the second ranging from 8915– 10982 Hz (mean = 9834; SD = 525) (Figure 4A). Air temperature of recorded calls varied from 22 to 23.5 °C. Call quantitative traits are summarized in Table 2. An additional pulsed note was noticed shortly after four advertisement calls from two recorded males (Figure 6) and other males heard in the field. Regular notes can gradually gain pulses until they become this note type (Figure 6). This note (n = 10) has a duration ranging from 68–116 ms (mean = 83 ± 16), is composed of 7–14 pulses (mean = 10.9 ± 2.1), lasting 2–9 ms (mean = 5 ± 1), is separated by intervals of 0–22 ms (mean = 4 ± 1), and is emitted at rates of 93–157 pulses per second (mean = 134 ± 22). The dominant frequency varies from 4436–4823 Hz (mean = 4630 ± 158); minimum frequency ranges 3747–3833 Hz (mean = 3781 ± 34) and maximum frequency ranges 4996–5125 Hz (mean = 5060 ± 42) (Figure 6). Another emphasized frequency band may be present, peaking from 8398–8570 Hz (mean = 8488 ± 59). Distribution. Pseudopaludicola florencei sp. nov. is known from its type locality, and in the municipality of Mutuípe, state of Bahia, Northeastern Brazil, and in the municipality of Nanuque, state of Minas Gerais, Southeastern Brazil (Darío Cardozo pers. Communication; see Figure 1). Mutuípe and Nanuque are situated about 200 km southeast and 560 km south of the type locality, respectively. Natural history. The holotype and paratypes collected on November 2016 were recorded on the banks of a river that crosses the urban area of Andaraí. In this place, we observed hundreds of specimens of P. florencei sp. nov. occurring syntopically with Dendropsophus sp. and Rhinella granulosa. We also have some call recordings of the seven paratypes from Área de Proteção Ambiental Marimbus-Iraquara, which is a protected site. In the field, we heard and recorded the additional pulsed note abovementioned. In all our field recordings, males were isolated at their calling sites, without any close-range encounters. However, there were dozens of males competing for calling sites at that night; it was possible to observe several males interacting physically. In these interactions, some males jumped quickly over the calling males, but no fighting was observed. Etymology. The specific name honors Antoine Hercule Romuald Florence. Better known as Hercule Florence, a French artist, painter, polygrapher, and inventor, is acknowledged as the inventor of photography in Brazil in the 19th century. After his return from the Langsdorff’s expedition (from 1826 to 1829), Florence developed a system able to properly describe animal sounds, transcribing them into a five line music staff (Florence 1831, 1876; Toledo & Araújo 2017). Such method, termed as “Zoophonie” by Florence, was the first universal method of describing animal sounds and he is therefore designated as the “father of bioacoustics” (Vielliard 1993; Toledo & Araújo 2017). At least these two techniques (photography and zoophony = bioacoustics) are fundamental for species description nowadays (Köhler et al. 2017). Specifically, bioacoustics has proved to be efficient in clarifying the taxonomy of the genus Pseudopaludicola (as in the present study). Phylogenetic inferences and mitochondrial DNA divergences.
