The dipsadine Schneider, 1801 subsequently fixed in 10% formalin and preserved in currently contains six recognized : Pseudoboa 70% alcohol. The voucher specimen was deposited coronata Schneider, 1801; Pseudoboa haasi (Boettger, in the Herpetological Collection of the Universidade 1905); Pseudoboa martinsi Zaher, Oliveira & Franco, Federal do Amapá under the care of Carlos Eduardo 2008; (Duméril, Bibron & Costa Campos (Fied number CECCAMPOS 2507). Duméril, 1854); Pseudoboa nigra (Duméril, Bibron The specimen was identified using the following & Duméril, 1854); and Pseudoboa serrana Morato, morphological characters from Starace (1998): (1) Moura-Leite, Prudente & Bérnils, 1995 (Frazão et al., uniform reddish dorsum and white venter; (2) dorsum of 2017). Three of these species, P. coronata, P. martinsi head black with a complete white collar in the parietal and P. neuwiedii, occur widely in the Amazon region, region; (3) dorsal scale rows 17-17-17; (4) ventrals with P. coronata being the most widely distributed 1+184; (5) undivided subcaudals 98; (6) supralabials (Costa et al., 2015). 7/7, 3rd and 4th contacting eye; (7) infralabials 8/8, Pseudoboa coronata is a moderate-sized, generalist 4th contacting upper chin shields; (8) postoculars 2/2, species that exhibits both terrestrial and semi-fossorial preoculars 1/1; (9) loreal present; (10) temporals 1+2/ habits, diurnal and nocturnal diel activity patterns, and 1+2; (11) snout-vent length 500 mm, head length 24.77 the ability to tolerate disturbed areas (Duellman, 2005). mm, and tail length 226 mm (31.1% TBL) (Figure Lizards, , and small mammals are its primary prey 1). This species differs from its congeners by having (Gaiarsa et al., 2013). The distribution of P. coronata 17 dorsal scale rows and uniform reddish or reddish extends from coastal and Venezuela to central brown dorsum in both juveniles and adults (Zaher et al., Bolivia and , with many occurrences from Acre, 2008). Amazonas, Maranhão, Mato Grosso, Pará, Rondônia, This record of P. coronata represents the first record and Roraima states within the Amazon basin of Brazil from Amapá state, extending its known distribution by (Bernarde et al., 2013; Costa et al., 2015). Despite its 355 km (straight line) from the nearest previously known wide distribution in the Amazon basin, this species is considered rare in some Amazonian areas (Cunha and Nascimento, 1993). Herein, we report a new record of Pseudoboa coronata from Amapá state in the eastern Amazon of Brazil. The new record of P. coronata were made during a herpetofaunal survey in the municipality of Serra do Navio (0.90275°N, 52.00497°W), Amapá state, Brazil. One specimen was collected in terra firme forest and
