Bioacoustics of Chiasmocleis supercilialba

VARIATION: Some variation in color pattern was observed from photos of live specimens (pl. 8) and examination of a paratype (USNM 342862: fig. 35). The dorsum can be dark brown, to almost uniformly whitish (silver) and may show reddish blotches and white spots (when not entirely whitish). A wide white stripe is almost invariably present from the snout to past the eyelids, sometimes extending to the inguinal region (forming the split stripe). A very narrow dorsal white line commonly present, extending from the occipital region to the cloacal region. Dorsal surfaces of forearm yellowish, orange or red, while dorsal surfaces of hind limbs usually follow the general dorsal pattern. As reported by Morales and McDiarmid (2009) the shape and number of inguinal and lateral blotches (or spots) is variable, but commonly dark brown. Throat region with intense brown reticulation over a white (or cream-colored) background. Chest, belly, and undersurfaces of limbs with large, dark brown spots or irregular blotches (fig. 35, pl. 8D, F, H). CALL AND TADPOLE: The advertisement call of C. supercilialba was described by Morales and McDiarmid (2009) . Call consists of a fast series of multipulsed notes (mean note duration 31.0 ms; mean interval between notes 37.0 ms) with dominant frequency between 2985.8–3205.0 Hz. Number of pulses per note not given. Tadpoles are unknown.
