[including S. agilis (Cruz & Peixoto) and S. argyreornatus (Miranda-Ribeiro)] of this species group occurring in the
Atlantic Forest of the State of Bahia in Brazil (Peixoto & Pimenta 2004; Pimenta et al. 2007; Pimenta & Carvalho-e-
Silva 2010). Moreover, the only tadpoles in these three species that have been described are those of S. argyreornatus
(Carvalho-e-Silva & Carvalho-e-Silva 1998). We describe herein the tadpole of S. strigilatus.

Although tadpole morphology provides relevant information for anuran taxonomy and systematics (see , only calls and adult morphology were evaluated in the description of this species. Herein, we describe and illustrate the external morphology and internal oral anatomy of L. oreomantis tadpoles and compare it with tadpoles of related species.

However, field studies showed that the iris color of F. erythrophthalmus could vary between yellow and red. To improve the recognition of these species we described the advertisement call of Frostius pernambucensis and Frostius erythrophthalmus and we tested if call characteristics are influenced by temperature, male size and perch height. We also report on a physical interaction between two males of F. pernambucensis and the associated vocalization, suggesting that F. pernambucensis has not a territorial call or encounter call. Comparing the advertisement calls, the call of F. pernambucensis was lower, shorter and with a smaller number of notes than the call of F. erythrophthalmus. Dominant frequency and fundamental frequency variation of the F. pernambucensis advertisement call were related to the male's size, while the call emission rate was related to air temperature. However, we could not find relationship among the acoustic characteristic of F. erythrophthalmus and male size or temperature.

The results reinforce one of the two species groups of A. albosignatus complex, which includes A. cavicola, A. ibirapitanga and A. leucopygius. Tadpoles of species of this group have anterior lip gap, three indentations in the posterior lip, labial tooth row formula 2(2)/4(1) and internarial distance greater than the distance between inner margins of the eyes orbits. For another group, in which A. sibilatus is included, we did not observe any characteristic in common. Tadpoles of A. sibilatus differ from those of other Aplastodiscus species by the dental formula variable 4(1,4)/7(1), 4(1,4)/6(1), 4(1,2,4)/6(1) e 3(1,3)/5(1).

Biota Neotrop. 10(2): http://www.biotaneotropica.org.br/ v10n2/en/abstract?inventory+bn02810022010. Abstract: We studied the richness and distribution of anuran species on different breeding sites at the Reserva Ecológica da Michelin (13° 50' S and 39° 10' W, approximately 90-400 m above sea level), Municipality of Igrapiúna, Bahia State, Brazil. The reserve includes fragments of Atlantic Rain Forest varying from 140 to 650 ha. Five types of environments were sampled: leaf litter inside forest fragments, streams inside forest fragments, dam on the edge of forest fragment, temporary pond inside forest, and temporary ponds inside banana and rubber groves along the eastern boundary of the reserve. We used active and passive sampling methods for surveys of amphibians, between March 2007 and December 2008. We captured 48 species distributed in 10 families (number of species in parentheses): Aromobatidae (1), Brachycephalidae (4), Bufonidae (2), Craugastoridae (1), Centrolenidae (1), Cycloramphidae (3), Hylidae (29), Leiuperidae (1), Leptodactylidae (3), and Microhylidae . Temporary ponds presented the highest number of species in reproductive activity (19 species in native forested areas, and 21 in plantation areas), while leaf litter presented the lowest (6 species). Two species were found in bromeliads (Phyllodytes melanomystax and P. luteolus). Twenty-two species were exclusive to fragments of forest, 11 were found only in anthropized areas (dam, and rubber and banana plantations) and 15 in both environments. Aplastodiscus cavicola and Dendropsophus giesleri had their geographic distribution extended to the State of Bahia. Phasmahyla timbo and Chiasmocleis cordeiroi known only from their type localities were found in the reserve.
