Figure 2. The lateral region in fixed specimens of some species of Cophomantini: A, Hypsiboas pulchellus (). B, Hypsiboas raniceps (). C, Bokermannohyla pseudopseudis (). D, Hypsiboas albopunctatus (). E, Aplastodiscus perviridis (). F, Aplastodiscus perviridis (). G, Hypsiboas heilprini (). H, Hypsiboas punctatus (; Brunetti et al., 2012). A, B, lateral regions in species lacking sexually dimorphic skin glands (SDSGs). C, D, lateral regions in species in which SDSGs are discernible only after histological analysis. Note that, in A–D, variation in the colour and structure of the skin is independent of the occurrence of SDSGs. E, F, the lateral gland in most cases is discernible only upon careful comparison between males (E) and females (F). E, G, H, in those cases in which it is macroscopically evident, the gland presents two different morphologies: slightly distinct skin yellowish or cream-coloured, with individual glands visible under high magnification (E, G), or pale yellow individual glands clearly distinguished without magnification (H). Note that the gland limits are often difficult to define macroscopically; broken lines indicate the putative limits of the glandular area. Scale bars = 5 mm.
