Lizards from the Alto Sertão region of Sergipe state, northeastern Brazil

Abstract We present the first detailed inventory of the lizard fauna of Alto Sertão region, west of Sergipe state, based on three field expeditions carried out by the authors and specimens deposited at the Herpetological Collection of Universidade Federal de Sergipe. The three inventories were carried out between 2010 and 2016, in the municipalities of Canindé de São Francisco, Poço Redondo, Monte Alegre de Sergipe, Nossa Senhora da Glória, and Porto da Folha. In total, we sampled 9,485 lizards of 19 species (10 families) of which 10 are new records for the study area. The most abundant species were Ameivula ocellifera, Tropidurus hispidus and T. semitaeniatus. Thirteen species were considered as widely distributed in Caatinga, five presented a relictual distribution and one was exotic. We suggest that future research focus mainly on non-sampled areas and should prioritize the municipalities of Gararu, Nossa Senhora da Glória and Nossa Senhora de Lourdes since they are localities with little or no sampling records.

摘要 本研究基于作者开展的三次野外考察以及保存在塞尔希培联邦大学（Universidade Federal de Sergipe）两栖爬行动物标本馆（Herpetological Collection）的馆藏标本，首次报道了巴西塞尔希培州西部阿尔托塞唐（Alto Sertão）地区的蜥蜴类区系详细名录。三次调查于2010至2016年间在圣弗朗西斯科坎迪德、红波索、塞尔希培蒙蒂阿莱格里、荣耀圣母城、福利亚港等市镇完成。本次研究共采集到隶属于10个科的19种蜥蜴共计9485号标本，其中10种为该研究区域的新分布记录。优势物种为眼斑澳菲沃蜥（Ameivula ocellifera）、糙鳞棘蜥（Tropidurus hispidus）以及半纹棘蜥（T. semitaeniatus）。本研究认定13种为卡廷加（Caatinga）干旱植被区广布物种，5种呈残遗分布格局，另有1种为外来物种。鉴于加拉鲁、荣耀圣母城以及卢尔德圣母城等市镇目前仅有极少甚至无采样记录，本研究建议后续研究优先聚焦上述未充分采样的区域。
