Herpetology Notes, volume 14: 539-550 (2021) (published online on 18 March 2021) Checklist of the reptiles from the Cancão Municipal Natural Park, state of Amapá, eastern Amazon, Brazil Carlos Eduardo Costa-Campos1,*, Patrick Ribeiro Sanches1, Fillipe Pedroso-Santos1, Vinicius A. M. B. de Figueiredo1, Rodrigo Tavares-Pinheiro1, and Wirley Almeida-Santos2 Abstract. The distribution of the reptile species in the eastern Amazon region is still poorly known. Here we give a list of reptile species from the Cancão Municipal Natural Park, municipality of Serra do Navio, state of Amapá, Brazil. We recorded through active search a total of 57 species, including two turtles, one crocodilian, 30 lizards, and 24 snakes. Two species, Mesoclemmys gibba (turtle) and Pseudoboa coronata (snake), were new records for the state of Amapá. The number of species in forested and open area environments accounted for 62.5% and 37.5 % of total species sampled, respectively. Of the 57 recorded species, 42 were assigned as Least Concern according to the Red List of Threatened Species from the International Union for Conservation of Nature, and 15 have not been evaluated so far. Our findings complement the available information about the distribution and richness of species that compose the herpetofauna of Amazonia. Keywords.

Herpetofauna is particularly diverse in Brazilian In the state of Amapá, herpetological inventories are Amazon, with more than 375 species of reptiles (Ávila- concentrated on anurans (Queiroz et al., 2011; Pereira- Pires and Prudente, 2019). However, this number is Júnior et al., 2013; Araújo and Costa-Campos, 2014; likely underestimated due to the vast Amazonian extent Campos et al., 2015; Benício and Lima, 2017; Lima (6 million km2) and many areas that remain remote or et al., 2017; Silva-e-Silva and Costa-Campos, 2018; difficult to access and are still poorly known in terms of Costa-Campos and Freire, 2019). Due to the lack of their herpetofauna (Azevedo-Ramos and Galatti, 2002; information about inventories on reptiles in the region, Ávila-Pires et al., 2007; Ávila-Pires et al., 2010). we present here the reptile species list based on novel Despite the growing number of studies addressing the data through field expeditions to the Cancão Municipal geographic distribution and richness of the Amazonian Natural Park, municipality of Serra do Navio, in state herpetofauna (e.g., Ávila-Pires et al., 2018; Fonseca of Amapá, Brazil. Additionally, we briefly address the et al., 2019; Debien et al., 2019; Freitas et al., 2020; species conservation status based on the IUCN (2020) Frazão et al., 2020), the diversity of these taxa in the and new distribution records of some species. state of Amapá is still poorly known. The state of Amapá has about 72 % of its territory covered by Materials and Methods protected areas (Dias et al., 2016). The majority of the state is within a continuum of 12 conservations units Study area. The Cancão Municipal Natural Park and five indigenous lands, representing an area of great (CMNP), a National Park category (SNUC, 2000) created by municipality of Serra do Navio, comprises 370 ha of Amazonian forest in the northwest centre portion of the state of Amapá, Brazil (Figure 1). The climate of the region is classified as Equatorial (Am of 1 Laboratório de Herpetologia, Departamento de Ciências Biológicas e da Saúde, Universidade Federal do Amapá, Köpper-Geiger classification), with average temperature Macapá, Amapá 68903-419, Brazil. of 27.6 ºC and rainfall annual of 2,850 mm (Alvares et 2 Secretaria Municipal de Turismo, Prefeitura Municipal de al., 2013).

Map of the Cancão Municipal Natural Park, in the municipality of Serra do Navio, state of Amapá, Brazil. the study area: (1) Terra Firme trail at Cancão forest Mesoclemmys gibba (Schweigger, 1812), Paleosuchus (0.90275°N, 52.00497°W) and (2) River Amapari trail trigonatus (Schneider, 1801), Corallus caninus (0.9008°N, 52.0134°W). Three sampling events were (Linnaeus, 1758), Sibon nebulatus (Linnaeus, 1758), conducted by three people in each of the two sites. Each Dipsas variegate (Duméril, Bibron & Duméril, 1854), sampling event consisted of two periods of three hours Philodryas olfersii (Lichtenstein, 1823), and Bothrops between 0900h-1200h (day) and 1800h-2100h (night), bilineatus bilineatus (Wied, 1821) were observed and through visual surveys (Corn and Bury, 1990; Franco et photographed (but not collected). Specimens of the first al., 2002). Therefore, the sampling effort employed in three species were not collected because we did not each site totalled 54 person-hours (3 people × 6 hours have a collecting permit when they were recorded, while × 3 sampling events). Pitfall traps with drift fences and specimens of the other species escaped during sampling. incidental encounters were not used in the sampling. Voucher specimens (ICMBio/SISBIO #48102-2) Data Analysis. We performed three accumulation were deposited in the Herpetological Collection of curves for (1) lizards, (2) snakes, and (3) all reptile Laboratório de Herpetologia from Universidade Federal species (turtles, crocodilian, lizards, and snakes) in do Amapá (Appendix I). The species conservation a combined analysis using the sample-based method status was based on the IUCN (2020). The taxonomic (Gotelli and Colwell, 2001) through 1000 randomisations nomenclature applied herein follows Costa and Bérnils of an abundance matrix where each column represents (2018). a species and each row represents a sample. We used species richness estimator Jacknife1 to determine the Results expected richness of (1) lizards, (2) snakes, and (3) reptiles combined. This analysis was performed using We recorded a total of 57 reptile species in the study EstimateS v.9.1.0 (Colwell, 2013). Species richness area, including two turtles, one crocodilian, 30 lizards, was calculated using the Menhinick’s index using PAST and 24 snakes (Table 1, Figures 2–5). The number of software (Hammer et al., 2001). species recorded in forest only (considering water Voucher specimens. Specimens were anesthetised environments in primary and secondary forests), in with 5 % lidocaine, fixed with 10 % formalin, and open area only, and in both (forest and open area preserved in 70 % ethanol (Heyer et al., 1994).
