The Advertisement Calls and Distribution of Two Sympatric Species of Chiasmocleis (Méhely 1904) (Anura, Microhylidae, Gastrophryninae) from the Atlantic Forest
The advertisement calls of Chiasmocleis cordeiroi and C. crucis are described for populations from the municipalities of Igrapiúna and Camacan, respectively, state of Bahia, Brazil. Both calls consist of multipulsed notes produced in series. Differences between the two calls are: dominant frequency, higher in C. cordeiroi (range 4500–4898 Hz; C. crucis range 4069–4435 Hz); note rate, higher in C. cordeiroi (range 6.20–7.46 s/note; C. crucis range 5.17–5.59 s/note); pulse rate, higher in C. cordeiroi (151.82–194.83 s/note; C. crucis range 125.30– 142.12 s/note); and the structure of the modulation patterns of the notes. Moreover, the advertisement calls of C. crucis and C. cordeiroi are more similar than the calls of all syntopic congeners. Furthermore, the current distribution of both species was extended.
