Redescription of the advertisement call of Aplastodiscus arildae (Cruz & Peixoto) and description of the call of Aplastodiscus weygoldti (Cruz & Peixoto) with general notes about the genus in Southeastern Brazil (Anura, Hylidae)
Abstract: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… Show more
“…(Cochran, 1955;Lutz, 1973;; among others). Some authors suggested a red-orange iris as a possible synapomorphy of the group (Carvalho-e-Silva and Carvalho-e-Silva, 2005;Orrico et al, 2006). However, we find that iris color varies among individuals of the same population; at the type locality of A. arildae, we recorded two individuals with coppercolored irises, whereas all other individuals had red irises.…”

“…Wells (2007) noted that calling from inside burrows, subterranean nests, and rock crevices can interfere with sound transmission, but in some species, the burrow facilitates resonance. In Aplastodiscus, only males of the A. albosignatus Group call from burrows, and these species have the lowest frequency of advertisement calls of all members of the genus (calls descriptions in Haddad and Sawaya, 2000;Garcia et al, 2001;Hartmann et al, 2004;Abrunhosa et al, 2005;Conte et al, 2005;Orrico et al, 2006;Zina and Haddad, 2006b). Lower frequency advertisement calls usually are associated with sound propagation over long distances, and the call of A. cavicola has the lowest frequency of all species in the A. albosignatus group (Abrunhosa et al, 2005).…”

“…Aplastodiscus is distributed mainly in the Atlantic Forest of northeastern, southeastern, and southern Brazil, and adjacent Argentina, with one species reaching gallery forests in the Cerrado biome in central-eastern Brazil (Frost, 2014). All but one species are green, with usually colorful eyes with hues of copper, orange, pink, red, violet, and white Peixoto, 1985, 1987;Garcia et al, 2001;Orrico et al, 2006). Aplastodiscus formerly was included in the genus Hyla Laurenti, 1768; because of the coloration of the frogs, they have traditionally been called " the green species" of Hyla of the Brazilian Atlantic Forest.…”
Green tree frogs of the genus Aplastodiscus occur in the Atlantic Forest and Cerrado biomes of South America. The genus comprises 15 medium-sized species placed in three species groups diagnosed mainly by cloacal morphology. A phylogenetic analysis was conducted to: (1) test the monophyly of these species groups; (2) explore the phylogenetic relationships among putative species; and (3) investigate species boundaries. The dataset included eight mitochondrial and nuclear gene fragments for up to 6642 bp per specimen. The results strongly support the monophyly of Aplastodiscus and of the A. albofrenatus and A. perviridis groups. Aplastodiscus sibilatus is the sister taxon of all other species of Aplastodiscus, making the A. albosignatus Group non-monophyletic as currently defined. At least six unnamed species are recognized for Aplastodiscus, increasing the diversity of the genus by 40%. A fourth species group, the A. sibilatus Group is recognized. Aplastodiscus musicus is transferred from the A. albofrenatus Group to the A. albosignatus Group, and A. callipygius is considered a junior synonym of A. albosignatus. Characters related to external cloacal morphology reveal an interesting evolutionary pattern of parallelisms and reversions, suggesting an undocumented level of complexity. We analyze, in light of our phylogenetic results, the evolution of reproductive biology and chromosome morphology in Aplastodiscus.

This study describes for the first time the female of Leptodactylus cupreus and provides new information concerning its geographical distribution, male's morphology and bioacustics. Leptodactylus cupreus, a poorly known species from the Brazilian Atlantic Forest, was originally allocated in the L. mystaceus complex of the L. fuscus species group. Based on morphological observations, we infer that L. cupreus should be in fact related to L. mystacinus, a species that, although assigned to the L. fuscus species group, is not assigned to the L. mystaceus complex. Therefore, we comment the phylogenetic relationships concerning L. cupreus, L. mystaceus and L. mystacinus.
