Abstract

We describe a new species of Leptophis (parrot snake) from the Cerrado ecoregion of Brazil. The new species, L. mystacinus sp. nov., differs from all other congeners in the following unique character combination: two Spectrum Green (129) to Light Parrot Green (133) dorsolateral stripes separated by a Buff (5) vertebral stripe, usually continuous onto the tail; loreal scale absent; postocular stripe Jet Black (300), wide and long (up 11 scales long onto nuchal region); maxillary teeth 21-25; ventrals 158-173; subcaudals 141-164; black spots on head absent; supracephalic plates of head not edged with black pigment; adult color pattern lacking dark oblique bands; keels absent on first dorsal scale rows; hemipenis unilobed, noncapitate, with undivided sulcus spermaticus, and first row of hemipenial body with four spines. Phylogenetic analysis of 16S mtDNA sequences indicate the new species is the sister taxon of L. dibernardoi, a species occurring in the neighboring Caatinga ecoregion.

巴西塞拉多一新种鹦鹉蛇，Leptophis（蛇纲：蛇科）。

我们描述了一种新的Leptophis（鹦鹉蛇）来自巴西塞拉多生态区。这个新种，L. mystacinus sp. nov.，不同于所有其他同属物种的独特特征组合如下：两条光谱绿（129）到浅鹦鹉绿（133）的背侧条纹，由一条浅黄色(5)椎条纹隔开，通常连续到尾巴；无局部尺度；毛后条纹喷黑色（300），宽和长（向上11鳞片长到颈部区域）；上颌牙21-25；腹侧158 - 173;subcaudals 141 - 164;头部无黑点；头的上片没有黑色颜料镶边；成人彩色图案缺乏暗斜带；龙骨在第一背部鳞片排上无；半阴茎不裂，无头状，具未裂的精沟，和第一排半阴茎体具四刺。16S mtDNA序列的系统发育分析表明，该新种是毗邻Caatinga生态区的L. dibernardoi的姐妹分类群。
