Important Character

Acoustic signals are the main mode of communication in anurans (Duellman & Trueb 1994). Calls produced by anurans play an essential role during their reproduction (Wells 1977) and advertisement calls emitted by males are, in many cases, species-specific, representing an important character for species recognition (Abrunhosa et al. 2001; Forti et al. 2010). Thus, the formal description of advertisement calls is relevant for anuran taxonomy (Pombal Jr. et al. 1995).

A New Species

Adults and tadpoles of a new species of the genus Leptodactylus are described from southeastern Brazil. Leptodactylus thomei sp.nov. can be found amidst the leaf litter within cocoa plantations along the northern coastal region of the state of Espírito Santo. It can be distinguished from other species of the Leptodactylus marmoratus group by its advertisement call, which is described, together with agonistic calls, and compared to advertisement calls of other species of the group that occur in southern and southeastern Brazil. The systematics of associated populations is discussed.

The Central American frogs of the genus Craugastor consist of 113 species (Hedges et al. 2008; Frost 2011). Craugastor gollmeri (Peters) occurs in lowland to highland forests of central Panama, the Caribbean versant of western Panama and eastern Costa Rica, even extending into the Pacific versant in northwestern Costa Rica, within an altitudinal distribution range of 10–1520 m (Savage 2002). At some localities, C. gollmeri has been found to be an usual to common forest species, being primarily a diurnal species that inhabits leaf-litter on the forest floor (Ibáñez et al. 1995; Savage 2002). The snout-vent length (SVL) of adult frogs is 30–36.5 mm in males and 45–54 mm in females (Savage 1987). The males of gollmeri species group lack vocal slits and vocal sac (Savage 1987), and seem incapable of producing vocalizations (Savage 2002). Nonetheless, here we describe the vocalizations given by a male of C. gollmeri in captivity, considered to be advertisement calls (sensu Wells 1977). The role of advertisement calls in species recognition and reproductive isolation has been well established (Wells 2007), hence, the relevance of call characters in anuran phylogenetic and systematic studies (e.g., Hoskin 2004).

We describe a new species of the Bokermannohyla circumdata group from the Estação de Pesquisa e Desenvolvimento Ambi-ental Galheiro (EPDA-Galheiro) (19o 12′S; 47o 08′W), Municipality of Perdizes, State of Minas Gerais, a mid-altitudinal (~ 850m above sea level) riparian forest environment in the Cerrado of southeastern Brazil. Bokermannohyla napolii sp. nov. is alliedto the large-sized species of the group, diagnosed on the basis of adult morphology/morphometrics, and mainly vocalizations.Adult specimens of the new species are most closely related to those of B. luctuosa and B. circumdata, but can be differentiatedfrom the former by having distal subarticular tubercle of finger III bifid/divided in males, and finger IV bifid/divided in malesand females; and from both B. luctuosa and B. circumdata by a distinctive advertisement call structure. We also provide bioa-coustic data on seven other species of the genus, including previously unknown advertisement calls of B. circumdata and B. carvalhoi, and re-description of the advertisement calls of B. luctuosa, B. ibitiguara, B. nanuzae, B. sazimai, and B. hylax.

Reassessment of the advertisement call of topotypic Scinax squalirostris (Anura: Hylidae), with an acoustic evaluation of its occurrence in the Serra da Mantiqueira, southeastern Brazil. Scinax squalirostris (Lutz, 1925) is thought to occur along a broad range in South America. The values reported for calls of topotypes differ substantially among studies. Because vocalizations often play a key role in uncovering cryptic diversity, the call of S. squalirostris is herein redescribed based on a new sample of topotypes. The call of a population from Poços de Caldas, Minas Gerais state, is also described. Topotypic advertisement calls have a dominant frequency between 3970 and 4125 Hz; 13–15 notes emitted at a rate of 24–27/s; call rate of 67/min and duration of 0.52–0.61 s; mid-call notes having 6 or 7 well-defined pulses, and an intra-note pulse rate of 223–266/s. Calls of the Poços de Caldas population have dominant frequency between 4083 and 4358 Hz; 15–18 notes emitted at a rate of 32–34/s; call rate of 64/min and duration of 0.46–0.56 s; mid-call notes having 6 or 8 well-defined pulses, and an intra-note pulse rate of 252–312/s. The advertisement calls of these populations have some differences with each other, and are promptly distinguished from calls of morphologically similar species. Our data to topotypes are inconsistent with some previously reported. A more detailed study of the population from Poços de Caldas is required, and more marked differences may be found in populations more distant from type locality of S. squalirostris.

Advertisement Calls

Anuran calls are conspicuous, diverse and subject to sexual selection. Many types of calls are described, but the most commonly studied is the advertisement call (Wells 2007; Toledo et al. 2014). Advertisement calls in anurans are emitted by males and some females (Toledo et al. 2014), and have the function of attracting conspecific mates and repelling male competitors. Because the advertisement calls of many species differ by such a magnitude that they serve as premating species (Heyer et al. 1996), it has been demonstrated that advertisement calls play an important role in species recognition, reproductive isolation, and may reflect evolutionary relations among taxa (Wells 2007; Escalona et al. 2018).

What Matters

The study of anuran advertisement calls is very significant for it is an important premating premating mechanism. Herein we redescribe the advertisement call of Aplastodiscus arildae from an area near type-locality and describe the advertisement call of A. weygoldti comparing them to previously described advertisement calls of species of the genus Aplastodiscus. Both advertisement calls are simple, non-modulated calls, very similar to each other, but significantly different in what matters to call duration. We describe the first distress call registered for the genus, the distress call of A. arildae, that does not have rigid form and was only recorded for one individual. Some general notes of the genus Aplastodiscus are given.

Species Specific

AbstractAcoustic conspecific recognition depends on spectral and temporal call properties, but not all of these are necessary for species identification. To test the importance of the advertisement call's internote interval of the dendrobatid frog Allobates (=Epipedobates) femoralis, we conducted field playback experiments with modified conspecific calls and investigated phonotactic responses. Allobates femoralis males showed positive phonotaxis when calls with internote intervals varying up to ±60% of the population's mean were presented. No phonotactic approach was observed in response to modified advertisement calls containing internote intervals of the syntopic heterospecific leptodactylid frog Adenomera hylaedactyla. However, 26.7% of the A. femoralis males tested showed positive phototoxic when altered advertisement calls with internote intervals of the syntopic heterospecific dendrobatid frog Epipedobates cf. hahneli were presented. Our results show that only a combination of different acoustic call parameters provides correct species-specific recognition.

First Time

For the first time, the amplitude-frequency and temporal characteristics of the acoustic signals (the distress one and two types of advertisement calls) of the Crimean gecko (Mediodactylus danilewskii) were analyzed. The distress call is a rather long one (usually around 150–350 ms, but sometimes up to nearly 1 s), with a peak frequency of 6.86 kHz in both males and females. The upper harmonics of this type of signal lie in the ultrasonic region of the frequency spectrum. The short advertisement call has a different duration in males and females, namely, about 23 ms and 35–40 ms on average, respectively. The peak frequency of this type of signal is 4.82 kHz in both sexes. Some frequency parameters of the acoustic signals are characterized by lower values in males than those in females, despite the larger body sizes of the latter. E.g., 35% and 11% of the total distress call energy is below 4 kHz in males and females, respectively. The average value of the fundamental frequency of short advertisement calls in males and females is 1.75 kHz and 3.33 kHz, respectively, while the limits of variability of this parameter in representatives of both sexes almost do not overlap. The prospects of using bioacoustics for solving important issues of the Mediodactylus (kotschyi) superspecies taxonomy are discussed. We assume that the male long advertisement call, which is a sequence with a duration of 4 to 9 s consisting of 24–44 clicks with an average peak frequency below 4 kHz following each other at a rate of 6.4–9.1 clicks/s, will be most informative for these goals.
