Nova espécie de Hyla Laurenti do grupo de H. microcephala Cope (Amphibia, Anura, Hylidae) do nordeste do Brasil

Abstract

A new species, attributed to the group of Hyla microcephala Cope, 1886, is described. The new species is close to H. bipunctata Spix, 1824, and it is found in Quebrangulo, State of Alagoas, in Northeastern Brazil. The eggs and larvae are also described and some ecological information is added. The new species is compared with other species of the same group, and with species of closely related groups that occur in syntopy. With H. bipunctata, it shares the general form of the body, the yellow ventral coloration and the orange color of the thighs, but it is distinguished by the dorsal Paris-green coloration (beige in H. bipunctata), absence of a dorsal pattern, light red thighs, and ornamentation of the upper lip with two or three yellow stains instead of the characteristic aureolate of H. bipunctata. With H. elegans Wied-Neuwied, 1824, it also shares the general form of the body and the ventral and the thighs coloration, but it is distinguished by the smaller size, absence of a dorsal pattern and light red thighs. From H. oliveirai Bokermann, 1963, the new species is distinguished by the dorsal coloration, the ornamentation of the upper lip and larger size. From H. branneri Cochran, 1948, it differs by the presence of the stains in the upper lip (just one in H. branneri), absence of the dorsal pattern and green dorsal coloration, which is more intense. The tadpole of the new species is provided.
