Abstract: The geographic distribution of Sphaenorhynchus lacteus Sphaenorhynchus lacteus comprises Amazon and Orinoco basins of South America, Guianas, eastern Brazil and Trinidad. Herein, we report for the first time the occurrence of and of the genus for the state of Piauí.

The genus Sphaenorhynchus vegetation just above the surface of the water. It has also been found under the leaf litter in tropical rainforest, and Tschudi, 1838 is characterized by small tree frogs with snout sharply inclined posteroventrally in lateral view. The skin on pondsin seasonally in open flooded areas (La agricultural Marca et al land.. 2008). At night, this semi the dorsum is smooth, and that on the belly is granular; aquaticIn the frog available congregates literature, at permanent in Brazil or the semi-permanent species occurs the tympanum is indistinct. The pupil is horizontally elliptical. The hands and feet are webbed; males have a et al. 2009) and northeast (state huge, median, subgular vocal sac and nuptial pads on the ofin the Maranhão) north (Acre, (La MarcaAmazonas, et al Pará and Rôndonia states)et al. thumbs (Rodriguez and Duelman 1994). 2009).(Gordo 2003; Caramaschi [SphaenorhynchusThe genus is composed carneus of fourteen Sphaenorhynchus species, three of . 2008; Caramaschi dorisaethem with distribution Sphaenorhynchus associated to the lacteus Amazon (Daudin, basin (Cope, 1868); Sphaenorhynchus During field work Sphaenorhynchusin July 2010 in the lacteus municipality were found of botocudo (Goin, 1957) and underBarras, the state leaves of Piauí of Ipomea (4°14’40” asarifolia S, 42°17’40” W), adult and Sphaenorhynchus1800)], ten to the Brazilian bromelicola Atlantic Forest [ juvenile specimens of Sphaenorhynchus Caramaschi, caramaschii Almeida, Toledo, and Gasparini, Garcia, Lingnau, 2009; , about 200 m away Sphaenorhynchus Bokermann, mirim 1966; from the nearest temporary pond (Figure 1).

The vegetation is characterized by (Lutz andSphaenorhynchus Lutz, 1938); planicola (Lutz transitional vegetation composed of “Scrubs” from Bokermann,Sphaenorhynchus 1966; prasinus Bokermann, Sphaenorhynchus 1973; surdus and Lutz, 1938); Sphaenorhynchus Bokermann, platycephalus1973 and (Cochran, 1953)], andSphaenorhynchus one with unknown lacteus distribution [ frog characterized (Werner, by the 1894)] snout (Frost pointed 2010). in dorsal view, the (Daudin, 1800) is a small tree fingers one-half and the toes four-fifths webbed, dermal flaps present lateral to the cloacal opening but absent on the heels. The dorsum is uniform green with a dark brown canthal stripe, the belly and outer margins of the limbs are white, the ventral surfaces of the limbs are bluish green and the iris is pale creamy bronze (Rodriguez and Duelman 1994). This species is found in flooded plains, floating (especially Eichhornia sp.) in forest clearings, at forest Figure 1.
