Brazilian Woodland Racer

distribution

Distribution. Found in Brazil and Paraguay, central portion of the South American open diagonal (Plt. 134 A). In Brazil, widespread in the Cerrado, with scattered records in open areas of Amazonia and upland areas of the Caatinga (Plt. 134 A), mostly at intermediate to high elevations (Plt. 134 B). Previous maps and taxonomy in Costa et al. (2013). Observed in the field in savanna (Valdujo et al., 2009).

Drymoluber brazili (Gomes 1918) Gomes 1918

Drymoluber brazili (Gomes, 1918) (Figs. 11.8 and 24.4) It was recorded for states of Piauí, Ceará, Paraíba, and Bahia. Occurs in altitudes between 334 and 1,100 m elevation. It was known from few localities in the Caatinga, but it seems to have wide distribution in the Cerrado region, to which it is considered endemic (Nogueira et al. 2011). This is a very rare snake, with few data on habitat use. Valdujo et al. (2009) report the use of typical cerrado savannas in Emas National Park, and Freitas and Silva (2007) report this species only to cerrado enclaves in Diamantina Plateau. Thus, this snake is probably associated to relictual savanna enclaves in the Caatinga region. The species has terrestrial habits, is diurnal, and feeds on vertebrates (Costa 2010).

description

About the type locality: In the 20 th century the Instituto Butantan often received snakes from several Brazilian localities, sent by collectors to the institute via the railroads that crossed some regions of the country at that time. Thus, the accuracy of localities of specimens from railroads (like the type series of D. brazili) must be treated with caution (Pereira et al. 2007). In the specific case of D. brazili, the Estação Ferroviária Engenheiro Lisboa (type locality), was located at km 555 of the Tronco-Catalão railroad, which, at the time of the collection of the holotype (September 1914) went from Campinas, São Paulo (- 22.09, - 47.05) to Ipameri, Goiás (- 17.72, - 48.15) (Giesbrecht 2009; Cavalcanti 2010). Although it is hard to identify the exact locality where the holotype of D. brazili was collected, we believe it really was in the proximities of the Tronco-Catalão railroad, since the road is located in areas with other confirmed records of the species (see map in Fig. 12). Similar locality problems exist with the paratypes that purportedly also are from rail stations. The Santa Eudóxia, Sampaio Vidal and Java stations, were part of a wide railroad network belonging to
