| ABSTRACT The integuments of ten treefrog species of two genera from Scinaxnae - O. angrensis (Lutz, 1973), O. flavoguttata (Lutz & Lutz, 1939), O. humilis (Lutz & Lutz, 1954), O. perpusilla (Lutz & Lutz, 1939), O. v-signata (Lutz, 1968), Scinax hayii (Barbour, 1909), S. similis (Cochran, 1952), O. trapicheroi (Lutz & Lutz, 1954) and S. x-signatus (Spix, 1824) - were investigated using conventional and histochemical techniques of light microscopy, and polarized light microscopy. All integuments showed the basic structure of the anuran integument. Moreover, the secretory portions of exocrine glands, such as serous merocrine and apocrine glands, were found to be restricted to the spongious dermis. Lipid content occurred together with the... |

| During the intervals of February 1993 to January 1994 and November 1994 to February 1995, in the southern São Paulo state, we studied the breeding activity of Scinax rizibilis (Bokermann, 1964), the only known hylid species with oviposition in foam nests. The foam nests were constructed by female jumps, during the oviposition. The clutches contained 850-1250 eggs, which were almost black, except for the small clear vegetative pole. The construction of foam nest in S. rizibilis is unique among the other species with this characteristic. The complexity of a foam nest is intermediate, and egg development was faster when eggs were surrounded by foam. It is possible to recognize a progression from less developed structures, represented by the bubble nests of... |
