中国广西中部掌突蟾属(无尾目:角蟾科)一新种描述

A new species of Leptobrachella (Anura: Megophryidae) from central Guangxi, China

  • 摘要: 该文结合形态、分子和鸣声数据,描述采集自广西中部大明山国家级自然保护区的掌突蟾属一新种,命名为大明山掌突蟾(Leptobrachella damingshanensis sp. nov. )。基于线粒体16S rRNA基因片段构建的系统发育树显示新种与L. nahangensis和夜神掌突蟾(L. nyx)关系较近。新种鉴别特征:雄性体长33.6-34.4 mm;大腿基本背面具一对明显凸起的橘红色腺体;背部皮肤粗糙具橘红色疣粒和短纵肤棱;腹面乳白色,其边缘聚集乳白色凸起的疣粒;指间无蹼亦无侧缘膜;趾间具蹼迹和窄的侧缘膜;体侧具零星不规则小黑斑;虹膜双色,上部棕红色,逐渐过渡到下部为淡银色。基于16S rRNA遗传距离显示新种与其它同属物种的遗传分歧大于4.7%。目前仅知道该新种分布在广西大明山国家级自然保护区海拔在1000–1200 m的常绿阔叶林溪沟周边。

     

    Abstract: A new species of the genus Leptobrachella, Leptobrachella damingshanensis sp. nov. is described from central Guangxi, China, based on morphological, molecular, and acoustic data. Phylogenetic analyses using a 16S rRNA gene fragment indicated that the new species formed an independent clade close to L. nahangensis and L. nyx. However, the new species differs from all known congeners based on a combination of the following characters: medium size (snout-vent length (SVL) 33.6–34.4 mm in males); pair of distinct jacinth humeral glands on proximal thigh area; rough dorsal skin with sparse jacinth tubercles and several short longitudinal ridges; creamy white ventral surface with small, creamy white glands on throat, chest, belly, and ventral surfaces of thighs, becoming more concentrated near lateral margin; webbing and lateral fringes absent on fingers, toes with rudimentary webbing and narrow lateral fringes; flanks with small irregular black spots; iris bicolored, upper half copper, fading to silver in lower half. Uncorrected p-distances were greater than 4.7% between Leptobrachella damingshanensis sp. nov. and all homologous DNA sequences available for the 16S rRNA gene. The new species is only known to occur in the Damingshan National Nature Reserve, where it inhabits montane evergreen forests between 1 000–1 200 m a.s.l.
