中新网南宁11月4日电(邓振海 林亿群)广西壮族自治区林业局4日介绍，广西自然博物馆科研团队近期在国际知名学术期刊Herpetozoa(中文译名《爬虫》)上发表重要研究成果，正式确认在广西雅长兰科植物国家级自然保护区发现掌突蟾属新物种——雅长掌突蟾。
据悉，科研团队在雅长保护区开展综合科学考察期间，于溪流中发现一批形态特殊的蝌蚪。经持续追踪，团队于2025年4月在同一区域采集到成年个体标本。通过对标本的综合分析，团队确认该物种与已知掌突蟾属存在显著差异，符合新种认定标准，遂以其发现地“雅长”命名，正式确认“雅长掌突蟾”这一新种。
雅长掌突蟾体型娇小，体表布满锥状疣粒，趾侧有窄缘膜但无蹼，其最突出的特征为双色虹膜——上半部铜橙，下半部灰褐。该物种目前仅分布于雅长保护区海拔800米至1200米的常绿阔叶林溪流环境中，对水质要求极高，被视为生态系统健康的指示物种。
此次雅长掌突蟾的发现，进一步印证了雅长保护区作为生物多样性热点地区的重要地位，也为今后开展区域物种形成与演化研究提供了新方向。(完)
