Herpetology Notes, volume 11: 405-408 (2018) (published online on 09 May 2018) New records of Glaucomastix cyanura and Ameivula nigrigula (Arias, De Carvalho, Rodrigues & Zaher, 2011) (Squamata: Teiidae) in the State of Bahia, Northeastern Brazil Karen Pinto-Silva1,* and Thiago Silva-Soares2 The family Teiidae Gray, 1827 is currently composed Sites, Rodrigues & Padial, 2016 to include the four of 157 species allocated in 19 genera, widely spread species of the former Ameivula littoralis group. throughout the New World, occurring from the Amongst these taxa are Glaucomastix cyanura and Neotropical region to North America (Krause et al. Ameivula nigrigula (Arias, De Carvalho, Rodrigues & 1985; Pough et al. 1998; Uetz et al. 2017). Amongst Zaher, 2011), two newly described species currently these genera, Cnemidophorus Wagler, 1830 which in known to few regions of Caatinga (Rocha et al. 2000; the past comprised a large amount of taxa distributed Dias et al. 2002; Arias et al. 2011a, b; Goicoechea et al. from the northern United States up to South America, 2016). Herein we present new records of these lizard was recently rearranged, and the South American species, extending their known distribution to different Cnemidophorus was divided into four complexes: C. directions, varying from ca. 80 to 160 km from the lemniscatus (Linnaeus, 1758), C. ocellifer (Spix, 1825), former known localities (see results and discussion for C. lacertoides (Duméril & Bibron, 1839), C. longicauda details). (Bell, 1843) (Wright 1993; Reeder et al. 2002, Giugliano During fieldwork on 28 February 2016 in the Serra et al. 2006). Harvey et al. (2012) in a taxonomic review do Palmeiral, municipality of Ipupiara, Bahia state of teiids allocated the species from C. ocellifer (Rocha, (11.831736°S, 42.484133°W; ca. 1028 m (Fig. 2) at Bamberg Araújo, & Vrcibradic, 2000) comprising 10 least six adult individuals of Glaucomastix cyanura species, and C. littoralis (Rocha, Bamberg Araújo, & were observed foraging on the litter and sand nearby Vrcibradic, 2000) comprising 4 species groups into rocky outcrops. A subadult specimen of G. cyanura Ameivula. Nevertheless, some authors do not accept (Fig. 1; MBML 3519), measuring 30.42 mm SVL was this new combination due to lack of phylogenetic collected and determined by T. Silva-Soares; deposited support (Cabrera 2012; Giugliano et al. 2013; Pyron at the Museu de Biologia Professor Mello Leitão. et al. 2013; Silva and Ávila-Pires 2013). Moreover, the Before this record, the species was only known from results of Goicoechea et al. (2016) did not support the two municipalities: the type locality in Morro do Chapéu phylogenetic relationship between Ameivula littoralis (11.550000°S, 41.150000°W; ca. 995 m), and Santo and Ameiva, hence, the authors proposed a new genus, Inácio, municipality of Gentio do Ouro (11.099857°S, Glaucomastix Goicoechea, Frost, De la Riva, Pellegrino, 42.716676°W; ca. 650 m), both located in Serra do Espinhaço state of Bahia, Northeastern Brazil (Arias et al. 2011a). Ameivula nigrigula was also found at Serra do Palmeiral, Ipupiara municipality (11.831736°S, 1 Museu Nacional, Universidade Federal do Rio de Janeiro, 42.484133°W; ca. 1024 m), occurring in sympatry with Laboratório de Herpetologia, Departamento de Vertebrados, Glaucomastix cyanura, collected and determined by Quinta da Boa Vista, s/nº, CEP 20940-040, Rio de Janeiro, T.
