Siphlophis longicaudatus Andersson, 1901

Distribution: Siphlophis longicaudatus is distributed in the Atlantic forests of southeastern and southern Brazil ( Lema, 1964; Prudente et al., 1998; Zaher & Prudente, 1999; Prudente & Feio, 2001; Alencar et al., 2009).

Habitat and time of activity: This moderate-sized pseudoboine (maximum SVL = 931 mm, female; this study) occurs mostly in forested areas ( Lema, 1964; R. Bérnils and F. Stender, unpublished data), although there is one record in an open area (Brazilian Cerrado; Alencar et al., 2009). There are only two available microhabitat records, one of an individual active on the ground ( Lema, 1964) and one on the vegetation ( R. Bérnils & F. Stender, unplublished data). There is only one record about time of activity, during the day ( R. Bérnils & F. Stender, unplublished data).

Feeding: Siphlophis longicaudatus seems to be a lizard specialist (N = 9, one Enyalius sp. , one Placossoma sp., 7 n. i.), although there are records of snakes as prey items (N = 3) ( Prudente et al., 1998; this study).

Reproduction: Clutch size varies from five to seven eggs (N = 6, mean = 6.0; R. Scartozzoni, unpublished data; C. Zatz, unpublished data; this study). The smallest mature female was 672 mm SVL (this study) and the smallest mature male was 624 mm SVL (this study) .
