Abstract

A new species of the genus Rhinella is described from Canavieiras, southern State of Bahia, in the Atlantic Rain Forest of Eastern Brazil. Rhinella hoogmoedi sp. nov. is characterized by the medium size for the genus (SVL 39.4-52.1 mm in males), snout rounded in dorsal view, with a vertical apical ridge which gives a nearly mucronate aspect, and nearly acute in profile, antorbital and supra-orbital crests developed, parietal crest poorly developed, post-orbital crest large, forming a small lateral ledge, tympanum evident, vertebral apophyses not salient on dorsum, presence of a dorsolateral line of pointed tubercles on the external border of the parotoid gland, continuing along the lateral side of body to the groin, a rounded tubercle at the posterior corner of mouth, and vocal slits present. The new species is distributed from the State of Ceará to the State of Paraná, Brazil.

Natural History of Pseudoboine Snakes

“…Reproduction: Clutch size varies from four to 15 eggs (mean = 7.9 eggs, N = 13; Vitt & Vangilder, 1983;Pizzatto, 2005;Scott Jr. et al, 2006;this study) and this species presents a continuous reproductive cycle (Pizzatto, 2005). Pizzatto (2005) found a significant sexual size dimorphism in snout-vent length for B. maculata, where females attain larger body size than males.…”

“…Distribution: Boiruna maculata is distributed from central Brazil to central Argentina with records in Uruguay (Abalos et al, 1964;Lema, 1994;Zaher, 1996;Achaval & Olmos, 1997;Nogueira, 2001;Leynaud & Bucher, 2005;Briguera et al, 2006;Kacoliris et al, 2006b;Scott Jr. et al, 2006;Hartmann & Giasson, 2008;Ghizoni et al, 2009). It appears to be a rare snake in Central Brazil (França & Araújo, 2006).…”

“…The tribe is composed mainly of moderate-sized snakes (Pizzatto & Marques, 2002;Scott Jr. et al, 2006) and encompasses Microhabitat was considered as the position of the animal in the environment while active. We considered the following categories: terrestrial, arboreal, semiarboreal, and fossorial (cf.…”

Clelia rustica (Jan, 1863) (Serpentes: Dipsadidae): distribution extension

“…The genus Clelia contains 13 species, five of which occur in a variety of habitats in Argentina (Scott et al 2006). Clelia rustica (Cope 1878) was described from "Argentina" and it is widely distributed along northern and central areas of the country reaching central-east Chubut province in the south as well as southern Brazil and Uruguay; however, most voucher specimens have been collected along the lower Paraná and Uruguay River basins and in eastern Tucumán province (Scott et al 2006).…”

Unique specimens have been cited for Chubut (Atlantic coast, Scrocchi and Viñas 1990), La Pampa (Tiranti and Avila 1997), Mendoza (Giraudo and Arzamendia 1997) and Río Negro (Atlantic coast, Scrocchi and Viñas 1990) provinces.…”
